[Emc-users] Home vs false limits
I am trying to write some gcode to carve a reasonable version of the spindle locker grizzly wants $90 for. But since I am using some g92 x0 y0 z0's in order to establish the center points of the circles that need cut, I find its impossible to re-run the code after stepping to where it miss-behaves, usually with a G2/G3 error, which forces me to manually re-execute all the motion code up to that point from manual entries in the MDI screen. What I need is the command line to use in the gcode file, right at the top, which will reset ALL the co-ordinate systems to the current G53 (machine) values. But all my reading of the user manual has not made me aware that there may be a gcode to do that. This call, FWIW, should be a null operation if the machine has not been homed. Is there such a beast? I am wearing out my new machine with the (run it up the post to the orginally homed positions) g53 g0 x0 y0 z0 (then zero it so the next moves can be absolute) G92 x0 y0 z0 (run it back to the center point of the currently being cut, circle) g1 f20 x#_target_x y#_target_y z#_target z ( now, make the next moves all be relative to the current position. G92 x0 y0 z0 MDI command chain, followed by running it back to where it came from, possibly with a different y location when it gets there.

There are 2 oword WHILE loops in this program. Each has an obypass test so the whole thing will be skipped while I troubleshoot the other. The machine has beem homed and is sitting at a DRO reading of x0 y0 z0 on entry to the program. Thats near the center of the xy travels, and about an inch down from the top of the post. Inside the IF for each loop, is a G10 L2 P1 X0 Y0 Z0 (to restore the homed co-ords to G54) G92 X0 Y0 Z0 (to make sure its not off a 0.0001) G1 F40 x(center of workpiece) y(offset to put tool at center of THIS circle) Z-8.828 (which is about 5 thou above the top surface of the workpiece as presently mounted) G92 x0 y0 z0 (subsequent motions s/b absolute moves from the present location as it has moved by the line above) Next move is a g1 f10 z-0.025 Error is move exceeds negative limit on axis 2 The machine is sitting at the homed position nearly 9 up the post and the DRO says everything is at 0,0,0,0. But while I can move it anyplace in its envelope, the code can't lower it 25 thou? ? ? Since it doesn't physicly exceed the negative limit, and I can then run it by hand, downward at least another 1.25 by the time I hit the minimumas set in the ini file for axis 2, I have no other choice but to believe that the interpreter is NOT checking the present position against the value in the machines own G53 map. No clue what its checking with, but the .ini files limits are not being hit. I can put this file, messy as it is because I've now been fighting with this for 2 full days now, on my web page if someone else wants to swing a mad cat, or a 4 foot oak 2x2 at me. Its on the Mill-stf page as 'make_spndle_lock.ngc' at the address in the sig. Thanks. Cheers, Gene Heskett -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Re: [Emc-users] Axis Drive Options
Hi John, I would first consider belts - more practically steel reinforced urethane timing belts made specifically for linear motion. (Perhaps they have Kevlar or Aramid now also..) I'd contact Gates Belts. They have a free engineering service that will take in all of your information and spit out some recommendations. There are some belt profiles designed specifically for linear motion drives. I think they are called the AX profiles, but I may have that wrong. The Gates guys would know. I've seen belts used in auto plants to transfer heavy transmissions parts and castings using linear belt drives at ridiculous speeds inside of cages (in case the parts come loose) - 24x7. I have also seen them used in press loaders that shuttle the parts so fast, that they are difficult to see. If they are properly sized they run for a very long time before requiring maintenance.

Re: [Emc-users] Axis Drive Options
Yea, I do prefer timing belts and used that on my plasma that goes up to 600 IPM on Nema 23 steppers. I did under size them at first for the X axis. Good thing precision is not an issue so I don't have to use the round tooth (expensive) belts the square tooth belts are good enough for this application.

Both of these, from what I've looked at with a scope, appear to be rs232
based, at about 9600 baud when I measure a bit time. The latest
purchase is an LCD, and has a home on a legacy computer in the basement.
The other is a 20 yo crt, with a db9 output that if I checked the baud
rate, its been forgotten because it was a decade ago.
I should look at fleabay see if they have any more, preferably in a 22
tv screen format like I am using on the new mill. Samsung tv, with a
failed tuner, still a good monitor though.

screens not all of us have. The only 2 I have are ancient grocery
store POS units I've no clue how to interface that with linux.

Many of these are a reprise of the power of open source
software.
I'm not surprised. :-)

[Emc-users] Axis Drive Options
I'm looking for some options for driving an axis at a maximum rate of 3000 IPM across a distance of 8' for the metric crowd that's 75 meters/minute for 2.5 meters. I don't need very accurate position and there are no cutting loads sorta like a big plasma gantry upside down. I do need encoder feedback to fire solenoids on the fly at various intervals. I'm thinking a jack shaft with either chains or belts to move the axis. JT -- ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
Re: [Emc-users] Axis Drive Options
Acceleration needs to be 10-20 times maximum velocity I'd think. Actually the gantry will be about 100 lbs as a rough estimate.

How fast are you going to accelerate? If the gantry weighs very much the acceleration/deceleration forces will be pretty large.

Re: [Emc-users] Tormach's Unexpected Benefits Of LinuxCNC
It's only a surprise if they release 'their' version of what is Open Source Software LinuxCNC to the rest of the world. Which I suspect they won't so it's really just a marketing ploy.
