Re: [Emc-users] 8255 driver
The so-called "pci_8255" driver in emc is *only* for the futurlec card with 3 8255 chips and a tiger-320 PCI bridge. It will not work without modification on any other type of card. (and according to user reports, not even that card works when any of the ports are set to input mode) Jeff - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

These "HALFILE ="'s will list the .hal files that are part of the initialization for starting your configuration in EMC2. One of these files will have "loadrt somedriver and_options" in it.

Re: [Emc-users] Step Direction Timing Page
John, I have run 3 of these on a mill without any major issues.the only problem I have found is that some of the revixsion of the controller pcb used opto isolators witha limiting resitor in series with led in the opto. this tends to cut down the highest speed you can run at. my fix on these was to bypass the resistor. later pcb used transitor which works beter. Unfortunatly when my old pc dies i lost my configs, but my top speed was limited to aprox 200mm/m on a 1mm pitch screw and 200 step/rev steppers. With timing, I didn't change any of the timing from the defaults in the sherline mm config. hope it helps. Jason Cox PS I can try to dig up a config file if you would like..

Re: [Emc-users] Running on a G4 MAc (new world)
Stephan, I am just working on the RTAI kernel at the moment under Ubuntu 8.04. Unfortunatly the last patch was on a 2.6.20 kernel and so I have to work out a patch for 2.6.24. My plan is to setup 2.6.24with a rtai kernel for a x86 and then port the powerpc rtai kernel patches in over the top. I hope this will give the least work as all the changes for the rtai common stuff will be in.

Re: [Emc-users] Overriding limits
Robert, I remember reading somewhere that you could have homing switches and travel beyond the homing switch. But even better would be to change the limit switches such that you do not loose 3 inches. Or just create a second machine configuration with manual homing. I've still not installed my limit switches so that's what I am using. But be aware: sometimes jogging goes beyond the programmed extends that I specified with stepconf.

There are lots of things that you can ignore at 4A but will bite you at 40A. If this was 180V DC instead of 90, I would go farther and say flat-out that an SCR based drive would make more sense than an H-bridge, but the low voltage changes things just a little. Some of the issues that need to be considered to decide between an SCR based drive and a MOSFET H-bridge: Torque ripple - H-bridge will be best, a three phase SCR drive will be good, a single phase SCR drive will produce some ripple. Whether that will affect your part finish or cause vibration will depend on the motor and the machine. Motor insulation life: The H-bridge produces fast-rising voltage edges which may or may not stress the motor winding insulation. Older motors are more likely to have problems. On the other hand, 90V is so low (I'm used to 480V stuff) that it is probably a non-issue. Input issues: Kirk didn't say what his available line voltage is. Four HP is a LOT for 120V single phase, regardless of the drive technology. On 240V single phase its not so bad. Three phase is ideal of course. SCR drives do not have large internal capacitors that need to be charged on startup - H-bridge drives do. In fact the dealing with the caps and their inrush current is one of more difficult challenges if you scale up a small H-bridge drive.

Re: [Emc-users] Off Topic, DC Spindle Motor
I have a Rivett lathe that uses a motor generator to supply the DC for the motor. That's a PITA. I have a rotary converter to generate the three phase to drive the motor generator to create the DC for the motor. When I was in the motor shop getting the commutator on the motor reworked, I spoke to someone there about what I was using the motor for. They had an off the shelf solution that took 120 or 240 (I forget which it was or whether it could work on either) in and generated DC for both the field and armature windings of a DC motor. It seemed to have variable speed control and was intended for this application. I believe the price was between $100-$200 dollars. (My motor is a 2HP.) I decided not to go that way because the lathe has a very nice bidirectional rheostat/reversing switch that I wouldn't want to replace right now. Also, the lathe doesn't get heavy use. If I ever convert to CNC, I'll look at that. Someone on some list suggested that DC motors have much better torque/horsepower curves than a corresponding 3ph motor with a VFD. That's another reason to stick with the DC motor.

Those who home to the part instead of using offsets will never use the touch-off button, and will home multiple times per session. Those who home the machine and then use work offsets will home each joint exactly one time, and then use the touch-off button. It's impossible to make both sets of people happy. Personally I'd like home and unhome to be side by side in a menu somewhere, since I use the second approach. I'd also like to see 'home' grayed out if you are already homed, and 'unhome' grayed out if you are not homed.

This discussion wandered a bit from the original. The problem starts with the placement of the home button next to jog which means it is easy to have the mouse wander when one is jogging while watching an edge finder. Ask me how I know. ;-) I believe the real fix here is to move 'home' someplace where homing is a more deliberate move rather than occasionally being accidentally triggered. I've always thought that the 'natural' location for the jogs was at opposite ends of the axis location. neg on the left and pos on the right. In the same fashion is is possible if one is careless (in a hurry) to exit Tkemc because the edit and exit are close to each other. > Dave - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

That is the "hobby" approach - there's nothing wrong with it really, but full size CNC machines would never do things that way. You lose the benefit of soft limits, as well as anything else that depends on knowing actual machine position. For example, screw error compensation only works if you know where you are on the screw. Homing the machine to a different spot for every job makes that impossible. > After playing with offset coordinate systems a bit I decided to change > the way I do things and set the Sherline up to use soft limits.

A move in > MDI would go right up to the limits with no complaints. It's a matter of personal preference really, but for convenience I'd be inclined to put the reference marks somewhere near the middle of travel. Then you don't spend time jogging all the way over to one end. I like my machine zero near the center of the travel anyway (for X and Y), but if you prefer machine zero near one end you can still put your reference marks in the middle - just set the HOME value in your ini file. For example, if zero is at the far left, and your reference mark is at 4", then set HOME to 4.000. When you jog to the mark and hit home, the machine position will immediately be set to 4.000. (Disclaimer - I'm not at home, and I haven't tested this. You might have to set HOME_OFFSET as well. If you try it, use a small value like 0.1" first, so if it decides to rapid by that amount when you hit home no harm will be done.) > I ran into in interesting quirk in Axis that didn't show up in Tkemc. > With home set to 0.0 and the minimum axis limit set to 0.0, as soon as > I homed all three axes the x axis would show as beyond limits.

Setting the soft limits 1 mm > outside the desired range also eliminated this issue. We've had debates before, about whether the exact limit position is the end of the places where you are allowed to go, or the start of the places where you aren't allowed to go. It's kind of like arguing about how many angels can dance on the head of a pin. The home position should NOT be at either extreme of travel. If you want the limits to go from zero to whatever, use a non-zero HOME. If you want HOME to be zero, use MIN_LIMIT that is less than zero and MAX_LIMIT that is more than zero.

Re: [Emc-users] "Un-Homing" an axis
I (now) understand the other side of the soft limit issue. I'd suggest though, that soft limits is the wrong way to save the table on the milling machine. I might rename soft limit to safety limit. You should NEVER hit the limit switch because if you do it at high speed, you can run right over it. The safety limit would prevent hitting the limit switch. I would then add a new soft limit that is soft in the sense that the user can move it to wherever he wants. He could replace the tool, touch the table, and then push a button saying set Z- soft limit. Similarly for Z+, X+, X-, Y+,Y-. That would be a some more work for the developers, but I think it would provide the desired functionality. Of course, one could imagine a facility that let the user manually run the tool around all of the clamps, chucks, fixtures, etc and set protective limits for them.

This is currently how override limits (for jogging off a limit switch) works, when the right and left limit signals are separate. If both ends are tied to one input, of course EMC can't tell which switch it's on, so it must allow jogging both ways. Here is some back-and-forth about this. You can see I have argued with myself about it over three years.

Re: [Emc-users] Problems configuring stepper machine
Aaron I use the MSD542 drivers with EMC2 with no problems, (but I don't have access to my ini file at the moment). The data sheet from www.motioncontrolproducts.com is a bit terse.

Missing steps could be due to velocity / acceleration settings (you need to test these in the stepper config wizard when you can), also check the coupling between your motors and leadscrews.

Re: [Emc-users] "Un-Homing" an axis
I believe that the way is *should* work is that overriding limits should override both hard and soft limits. Compared to overriding hard limits, overriding soft limits is harmless. For additional protection though, overriding limits should allow jogging only *away* from the limit that has been hit. That would solve the problem very nicely, I think. Of course, I have no idea about how difficult this might be to implement. :-) Ken Kenneth Lerman Mark Kenny Products Company, LLC 55 Main Street Newtown, CT 06470 888-ISO-SEVO 203-426-7166 - Original Message - From: "John Thornton" <[EMAIL PROTECTED]> To: "Enhanced Machine Controller (EMC)" Sent: Friday, May 02, 2008 8:26 AM Subject: Re: [Emc-users] "Un-Homing" an axis > You would think that a jog override for soft limits would be nice.
