[Emc-users] Mesa 5I25 Stepping when linuxcnc is not running
Hi, Today I converted a mill form parport to 5I25, using 5i25_r990x2.bit bitfile. Everything was running good. Having a mesa card, I wanter to increase the speed. When I closed linuxcnc, X and Y ran into the endstops at full speed. Thinking of watchdog problems, I removed the pet function from the servo thread. The hal pin indicates the watchdog has bitten, and I get no steps. But when I exit linuxcnc I get steps in X and Y. Rebooting shows that the steps are generated as soon as I press the power button, and do not stop until I start Linuxcnc. I already tried reflashing the bitfile. As far as I can see the watchdog should bite when linuxcnc is not running, switching outputs to high impedance. The drives are connected via 330R and an 6N137. http://www.uhu-servo.de/UHU_PCB_3_13.pdf There is no way they can move on high impedance input. They stop moving when I pull the cable from the mesa card. The same setup rund without problems using the parport, apart from a few steps generated during bootup. I have another mill with a similar setup, but with a chargepump. A chargepump will fix this, but anyway, the mesa card must not output steps when Linuxcnc is not running… Rene -- HPCC Systems Open Source Big Data Platform from LexisNexis Risk Solutions Find What Matters Most in Your Big Data with HPCC Systems Open Source.

Re: [Emc-users] New trajectory planner merged into LinuxCNC's development branch
The new TP behavior is on by default in master. If you have no TP settings in your [TRAJ] section - linuxcnc defaults to. ARC_BLEND_ENABLE = 1 ARC_BLEND_FALLBACK_ENABLE = 0 ARC_BLEND_OPTIMIZATION_DEPTH = 50 ARC_BLEND_GAP_CYCLES = 4 ARC_BLEND_RAMP_FREQ = 100 I have cut and pasted some info from Robs post on the forum - helps explain each setting -ARC_BLEND_ENABLE = 1 Turn on new TP. If set to 0 TP uses parabolic blending (1 segment look ahead.) Default value 1. -ARC_BLEND_FALLBACK_ENABLE = 0 Optionally fall back to parabolic blends if the estimated speed is faster. However, this estimate is rough, and it seems that just disabling it gives better performance. Default value 0. -ARC_BLEND_OPTIMIZATION_DEPTH = 50 Lookahead depth in number of segments. To expand on this a bit, you can choose this value somewhat arbitrarily. Here's a formula to estimate how much depth you need for a particular config: # n = v_max / (2.0 * a_max * t_c) # where: # n = optimization depth # v_max = max axis velocity (UU / sec) # a_max = max axis acceleration (UU / sec) # t_c = servo period (seconds) So, a machine with a maximum axis velocity of 10 IPS, a max acceleration of 100 IPS^2, and a servo period of 0.001 sec would need: 10 / (2.0 * 100 * 0.001) = 50 segments to always reach maximum velocity along the fastest axis. In practice, this number isn't that important to tune, since the lookahead rarely needs the full depth unless you have lots of very short segments. If during testing, you notice strange slowdowns and can't figure out where they come from, first try increasing this depth using the formula above. If you still see strange slowdowns, it may be because you have short segments in the program. If this is the case, try adding a small tolerance for Naive CAM detection. A good rule of thumb is this: # min_length ~= v_req * t_c # where: # v_req = desired velocity in UU / sec # t_c = servo period (seconds) If you want to travel along a path at 1 IPS = 60 IPM, and your servo period is 0.001 sec, then any segments shorter than min_length will slow the path down. If you set Naive CAM tolerance to around this min length, overly short segments will be combined together to eliminate this bottleneck. Of course, setting the tolerance too high means big path deviations, so you have to play with it a bit to find a good value. I'd start at 1/2 of the min_length, then work up as needed. -ARC_BLEND_GAP_CYCLES = 4 How short the previous segment must be before the trajectory planner consumes it Often, a circular arc blend will leave short line segments in between the blends. Since the geometry has to be circular, we can't blend over all of a line if the next one is a little shorter. Since the trajectory planner has to touch each segment at least once, it means that very tiny segments will slow things down significantly. My fix to this way to consume the short segment by making it a part of the blend arc. Since the line+blend is one segment, we don't have to slow down to hit the very short segment. Likely, you won't need to touch this setting. -ARC_BLEND_RAMP_FREQ = 20 This is a cutoff frequency for using ramped velocity Ramped velocity in this case just means constant acceleration over the whole segment. This is less optimal than a trapezoidal velocity profile, since the acceleration is not maximized. However, if the segment is short enough, there isn't enough time to accelerate much before we hit the next segment. Recall the short line segments from the previous example. Since they're lines, there's no cornering acceleration, so we're free to accelerate up to the requested speed. However, if this line is between two arcs, then it will have to quickly decelerate again to be within the maximum speed of the next segment. This means that we have a spike of acceleration, then a spike of deceleration, causing a large jerk, for very little performance gain. This setting is a way to eliminate this jerk for short segments. Basically, if a segment will complete in less time than 1 / ARC_BLEND_RAMP_FREQ, we don't bother with a trapezoidal velocity profile on that segment, and use constant acceleration. (Setting ARC_BLEND_RAMP_FREQ = 1000 is equivalent to always using trapezoidal acceleration, if the servo loop is 1kHz). I had considered making the RAMP_FREQ into a time instead, but it seems like the idea of a cutoff frequency is more intuitive, at least to a controls engineer. expanding further You can characterize the worst-case loss of performance by comparing the velocity that a trapezoidal profile reaches vs. the ramp: # v_ripple = a_max / (4.0 * f) # where: # v_ripple = average velocity loss due to ramping # a_max = max axis acceleration # f = cutoff frequency from INI For the aforementioned machine, the ripple for a 20Hz cutoff frequency is 100 / (4 * 20) = 1.25 IPS. This seems high, but keep in mind that it is only a worst-case estimate. In reality , the

Re: [Emc-users] Feed control
It was interesting help in all aspects. World is theater and people actors. So we all play some role. It did not discourage me. Why? Less than 7 month ago The United States Government could not find smart contractor to make gov. health care web to work properly. We are talking about The United States Government! Order to build such web looks like was given about a year -12 month ahead of time. The result – was disaster – nothing was working right. Question is why smart people around of word did not react and help to The United States Government? Or maybe they did!! Or probably they set similar respond that I got. Why not? Sounds like a comedy story, but very probable one. Who was the contractor for the US Government – big software company – and it was not for FREE for sure. Another fact. In State of Oregon, Government of State of Oregon contracted similar job- similar web for health care to ORACLE -- http://www.oracle.com/index.html-- who does not know it??? Own by famous Lawrence Joseph Larry Ellison - http://en.wikipedia.org/wiki/Larry_Ellison And after spending many millions – web for Oregon still did not work right—Gov. of State of Oregon decided to abandon all work that was done by ORACLE and joint the federal gov medical web. 1--- “You are a bottomless pit of a sense of entitlement.” 2 “Please, use your grey cells to understand” 3“giving a man a fish versus teaching him, how to catch a fish.” 4“demanding a free consultation, and then not taking the medicine he prescribes for you! What was that you were saying about logic and common sense?” 5“What you are doing now is not working.” 6“for what you want to do and then ask for bids for the work.” 7“help your are all wasting their time and are obviously frustrated.” 8-“ask for bids for the work.” 9“I think you should control your anger. Never seen anybody calling you stupid or brainless. Neither seen anybody being disrespectful to you.” Just look remarkable statements above. Did United State government received similar because of web for health care? This is not LinuxCNC this is major web creation. Much More companies it web creation business Why ORACLE could not do it? Maybe same people that address angry e-mal to me can share their valuable opinion with Larry Ellison /ORACLE--about why web for State of Oregon could not be fix? A lot to learn from this e-mail.

Re: [Emc-users] .pit file extension
Rick, More information about the original controls might help. Many people on this list have used regular CNC turning centers. Exact make and model of the original control and the lathe would be a good start. Do you have any manuals for it now? Often the service or electrical manual will have ladder diagrams for the PLC portion of the control. If we don't have what you need on this group, you could pose a question to the Practical Machinist CNC forum, where someone is likely to have the exact manual you need or could otherwise get you information on your machine's turret operation. -- Ralph From: Rick Lair [r...@superiorroll.com] Sent: Thursday, June 12, 2014 10:51 AM To: emc-users@lists.sourceforge.net Subject: Re: [Emc-users] .pit file extension Thanks Guys, The first thing I found was Frhed on a Google search for hex editor, and it work fine, opened it up and now I just have to be able to decipher it, way over my head.

Re: [Emc-users] Ball Screw Drive?
On Thursday 12 June 2014 17:09:45 rayj did opine And Gene did reply: A general question on using two motors in this situation. I'm using steppers, so I'll frame the question for them. Assuming identical motors and driver boards, is it possible to wire both driver boards to the same output from the breakout board. Example: run the wires from the BOB X-axis step pin to the step input for 2 drivers and the X-axis direction pin to dir input on both drivers? Power, watch dog, etc. wired as necessary for safe operation. Generally speaking, Not before a good, gantry is square, home has been achieved. Why? Because there are going to be residual mechanical sync errors between the two motors that will push one or both to be slightly out of sync with the other when powered down, that, coupled with the fact that most stepper drivers power up at what they think is the home/index position, and the motors will turn to the nearest position from where they are, making it possible that they are a major portion of a full step out of sync just from being powered up. How far out of square the gantry is depends on your gear ratio's of course. The ideal situation would seem to be a switch on each end of the gantry, that when it is just closed, would stop the driver on that side while allowing the other side to continue looking for its switch. And I would like to see a counter that would stop it and advise the operator there is a potential square error if it counts to 1 or 2 more than the driver is microstepping. Something in the drive on one end or the other may have slipped. Such a warning might save you from making 20 parts, all of which are out of square. Once this synced state has been achieved, then it might be feasable to drop to one stepgen. But since you had to have two to home properly, you may as well go ahead and use both. 2nd question: Is there a glossary/dictionary of terms/acronyms used regularly on this list. I have a hard time figuring some of them out. I'm thinking of LCNC/machining terms, specifically. TIA ISTR there is a glossary in the various pdf manuals, last couple of pages are where I'd check. I hope this is helpful Raymond, but someone else here may have a better idea.

It looks like the mechanical drawbacks of trying to use 1 motor may be outweighing the configuration issues in Linuxcnc. My opinion is the most stable way to do it is with a drive shaft in the middle that has two cogged pullies or sprockets at each end and a matching cogged pulley or sprocket at each end of the long ballscrews. Run two belts or chains at each end, one to each side. If the motor is double shaft it could be put in the center of the drive shaft under the table to further reduce torsional flex. Or if the current setup is using one chain or belt connecting the ballscrews at one end, with the other ends free, just duplicate the connection at the other end. That should help some but not as much as keeping any one piece of the drive system as short as possible. I am still in the stage of working out plans and strategies to propose to my superiors.

Re: [Emc-users] Ball Screw Drive?
A general question on using two motors in this situation. I'm using steppers, so I'll frame the question for them. Assuming identical motors and driver boards, is it possible to wire both driver boards to the same output from the breakout board. Example: run the wires from the BOB X-axis step pin to the step input for 2 drivers and the X-axis direction pin to dir input on both drivers? Power, watch dog, etc. wired as necessary for safe operation. 2nd question: Is there a glossary/dictionary of terms/acronyms used regularly on this list. I have a hard time figuring some of them out. I'm thinking of LCNC/machining terms, specifically.

Re: [Emc-users] Ball Screw Drive?
I wondered if that might be a problem. I'm thinking I could use a manual pulse generator to square it up at startup and have a set of home switches that could be touched off on as necessary to assure that the system is still square. If it isn't then the operation would be stopped and it could be manually squared again. It is my understanding that the usual cause of missed steps is heavy loading of the motor. Assuming this is minimized, I think this might be a viable system. Keep in mind that this a hobby setup, so other things besides pure economics drive the decisions.

Power, watch dog, etc. wired as necessary for safe operation. Generally speaking, Not before a good, gantry is square, home has been achieved. Why? Because there are going to be residual mechanical sync errors between the two motors that will push one or both to be slightly out of sync with the other when powered down, that, coupled with the fact that most stepper drivers power up at what they think is the home/index position, and the motors will turn to the nearest position from where they are, making it possible that they are a major portion of a full step out of sync just from being powered up. How far out of square the gantry is depends on your gear ratio's of course. The ideal situation would seem to be a switch on each end of the gantry, that when it is just closed, would stop the driver on that side while allowing the other side to continue looking for its switch. And I would like to see a counter that would stop it and advise the operator there is a potential square error if it counts to 1 or 2 more than the driver is microstepping. Something in the drive on one end or the other may have slipped. Such a warning might save you from making 20 parts, all of which are out of square. Once this synced state has been achieved, then it might be feasable to drop to one stepgen. But since you had to have two to home properly, you may as well go ahead and use both. 2nd question: Is there a glossary/dictionary of terms/acronyms used regularly on this list.

If it isn't then the operation would be stopped and it could be manually squared again. With a box in the data line so you could do that manually, it ought to be doable. It is my understanding that the usual cause of missed steps is heavy loading of the motor. Assuming this is minimized, I think this might be a viable system. Two ways to lose it actually. Accelerations that exceed what it can do are one, and heavy loading would be the other, both coming into more obvious play when the motor voltages are less than 30 volts. Even 30 volts rules out using the single chip drivers as that is about the point where they let out all the smoke don't work any more. Keep in mind that this a hobby setup, so other things besides pure economics drive the decisions. Here, I have just 2 machines, an old HF micromill with the LMS bigger table kit, 4 axis's, running on a medical grade (for whatever thats worth) 28 volt 12.5 amp supply. And a 7x12 lathe running on a home made supply making about 38 volts and 5 or so amps. Both are using the 2M542 driver, up to 4.2 amps 50 volts. The difference in PSU voltage translates to the lathe being able to move at 3 or 4 times the mills speed, with the mill getting stally when I ask it for 15 ipm. The lathe with the additional 10 volts can move the X at a little better than 60 ipm. That 2M542 driver seems to be bulletproof, when I threw out the A-3977 based single chip drivers because yet another had blown, I bought a spare, and 2+ years later it is still in its packing box in a drawer of the tool chest. Careful shopping on ebay can probably buy them at about 50 bucks a driver.

On 12 Jun 2014, at 02:34, Todd Zuercher zuerc...@embarqmail.com wrote: The machine is one that has had a problematic (under engineered drive train) from the get-go. It is an 8 spindle gang router for wood carving, with a 12ft long gantry that has about 5ft of travel (Y-axis). Even though the X is on a 12ft gantry it only has a little over 3ft of usable travel. X and Z both currently use 0 backlash lead screws (these are showing some age) and I want to replace them with ball screws, with a shorter pitch and instal better fixing blocks (what is there now is pretty el cheapo and is adding a lot of backlash). When reducing the pitch, you can have a higher thrust. Mainiainting the same speed means you’ll have higher RPM. When designing the fixing bearing construction there’s deciding which side of the spindle to fix, an which to slide. The spindle is not only about the ratio, the geometry (diameter) of the spindle and it’s lengths have a great influence I’d advice doing some calculations on buckling and vibrations for the spindles max RPM and thrust. most vendors have example calculations. My hope is to reduce backlash, reduce friction, and increase mechanical advantage, in the hope of improving acceleration and stability. The changes on the Z will change the encoder resolution from about 8K counts/inch to about 10K, X will go from about 4.5K to 10K. this all sounds relatively simple so far. That leaves the problem child Y axis. It has a helical rack and pinion (~2 inch diameter pinion) on each end of the gantry connected together by 2.5 inch diameter torsion tube. The drive is on the outside and consists of a large fine toothed timing belt pulley (about 8 inch diameter on the pinion shaft) and a very very small one on the servo motor (less than .75). Tooth count on the big one is 212, and I can't see the little one to count it right now it might be as small as 14 teeth. Regardless what the actual ratios are, a 2000 count (8K quad) encoder on the motor gives about 7.5K count/inch. Other than the step motor esque gearing, I think my biggest problem is belt squirm on the ultra small motor pulley. I think a would be happy with +-0.001 inches accuracy and satisfied with +-.002 The machine is all aluminum construction so is far from heavy duty, but it isn't some light hobby job either. All the servos are 850oz/in. (I think I'll have to check the numbers to be sure). I was considering just putting a ball screw on just one side of the gantry and leaving the racks and pinions alone (still connected). I know it kind of still leaves the far side to flop around, but it's doing that already (torsional flex is a bitch ain't it). yes it is :) Especially because you want the nut of the spindle to be parallel with the axis. If you have forces other than pure couple, then the life of the ball nut is reduced. I had thought about using 2 90 deg gear boxes, but their expense and fear of backlash has me shying away. I may be best just biting the bullet and going the 2 motor route. - Original Message - From: Bas de Bruijn bdebru...@luminize.nl To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Wednesday, June 11, 2014 1:52:55 PM Subject: Re: [Emc-users] Ball Screw Drive?

Hi Todd, could you elaborate a little bit on the actual setup? Do you want to rotate the nut on the gantry, or do you want to rotate the spindles on the frame beneath? Either way, if you want to use 1 motor, then position it in the middle so elasticity (I roughly calculate 3 feet in 1 meter) over the 4 meters is equal on both sides. Otherwise you will have one of the nuts/spindles lagging w.r.t. the other one. What is the torque you expect? and the tolerance you expect to mill? What kind of finish (part/component quality) are you after? - 2 90 degree gearboxes with a shrink collar could be used. with a gearbox in the middle. - Another way could be to put bevel gears on the end of the spindle and drive that with 1 axis (again, motor in the middle). - or you could use an eccentric plate construction. A motor with an eccenter who drives 1 plate. That plate is held in place by 3 executers. Then you put an executer on both spindels/nuts and when the eccentric plate starts to move the spindle/nut will be rotated. You’ll have a bad time fighting vibrations :) you’ll need to counterbalance it so I guess it gets a little bulky. To get the idea: something like this, http://www.google.com/patents/US2342251 or http://www.google.pl/patents/US4260301 -- Todd Zuercher
