Galil / Re: X,W home problems

« on: September 02, 2010, 11:01:26 AM »

Well still no luck with the new plugin.
It does the X fine, but gets stuck with the W and then I can't move off because it is still on the limit switch of the W axis.

I am posting the debug file.

Galil / Re: X,W home problems

« on: September 01, 2010, 10:59:00 PM »

PM Sent.
I was looking at the old software's source code and it used the find edge galil command.
The procedure would sent the speed low, unlock the X and W, use find edge to stop on the limit switches (squaring the gantry) and then move off the switches even slower with find edge again, and relock the X and W.

I was thinking of writing a program into the galil card then calling it with a plugin message with a VB button if nothing else worked.

Galil / X,W home problems

« on: August 31, 2010, 04:55:23 PM »

I am trying to get a large machine that is a rack and pinion drive with encoders & scales on all axis's.
The X and W are slaved together, but when I use the home routine I can't get them to square even with the square settings.

The home and lower limit switch are the same, so I am using the limits as homes.

The problem is that it will home the X side and move off the switch, but then it stays on the limit on the W side and nothing happens.

Is it possible to write my own galil code for the home sequence?
I have the code from the old software, so I want to use the same galil commands to home the machine.

Thanks
Dave.

General Mach Discussion / Estop with limits

« on: August 31, 2010, 09:49:58 AM »

Is it possible to NOT have the Estop activated when a limit switch is hit when jogging?

I would prefer it to just not allow me to move in that direction anymore.

Thanks

Thanks.

I am trying to get a temp wiring bypass from the old controller to the new one with mach so I can test this out soon, so I will let you know how it works out either way.

It sounds like it will work pretty good.
Are you able to make it so that the clamp will activate as soon as the X and Y distance to go reach 0, and then they deactivate when the Z has retracted to a set value? And possibly a time delay between the turn off and the start of the next XY movement?

I know I am asking alot, but would I be able to get the source to the plug in? I want to learn how to start making them as well. 

Thanks.

I have mapped the output#1 to a relay on the PLC and I cannot see it unclamping at the bottom of the stroke. It seems to stay clamped from the start of the hole till the retract is finished.
But I don't have motors hooked up yet to fully see how it plays together.

Well I think I have a working brain program for this.
I took 3 values, Xtogo Ytogo Ztogo
Made them all have a =0 check
Inverted the Ztogo = 0 check
Then did a AND on all 3 and route it to Output #1

So it is basicly If (Xtogo and Ytogo = 0) AND (Ztogo is not 0) then clamp the bed.

It looks like it is working in simulation, but do you see any problems with it?

They pause it for breaks because the drilling we do can go really wrong really fast in no one is watching.

I think brains should run fast on my system since it is using a galil motion card on ethernet and a Click PLC with modbus for the outputs, so no printer port.

I have the card and plc all setup with mach but I havent connected it to the servo amps since I want to get all the motion clamps and tool change setup first.

All the operators here are used to using single block to pause after the current hole to go for break.
It works well with our DOS and Fanuc controllers.

But when I test this with mach is will pause the hole, but then when you resume with a cycle start, it will just use the drilling feed rate to position to the next hole and not drill it. And then continues with this positioning and not drilling.
