It may indeed be servo lag.  Set the Galil Feature "off on error" and set the following error threshold to something like .100"  If the drive motor trips off, then you need to tighten up your PID loop.

Galil / Re: Spindle speed control w/2280 & VFD
« on: January 05, 2010, 11:22:28 PM »
Mike,

Theoretically, you would set up your pulley ratios in Mach and use the spindle axis in the Galil plugin to output +-10v to control both speed and direction.  But...  I have not tested this at all.  My spindle uses and encoder and it is not using pulleys (motor speed == spindle speed), so that's a pretty simple setup.  Until I can mock up a VFD spindle, I can't say how the plugin will react.  But the code is meant to do as I described.  It's just not proven out.

Galil / Re: Galil and parallel port

Unfortunately, no.  :(

But you can run an MPG off the Galil.  And use it's I/O.  It you need more I/O, you can use a Galil RIO via ModBus.

Servos or Steppers? 

If steppers, you are losing steps. 

If servos with encoders on the motor, something mechanical is slipping.  For servos, the Galil gets it's feedback from the motor encoders.  If the numbers are right, then the motor shaft went through all of it's paces.  But the screw may not have!  Check your couplings and/or pulleys for slippage on the shafts.

Galil / Re: Galil controller compatability (what works with the plugin)

Jim,

You will never notice the ASCII processing.  As it turns out, it's not an issue at all.  You want SmartTERM.  It comes with the Version 7 drivers.  Don't use GalilTools-lite.

Mach SDK plugin questions and answers. / Re: PLUG IN WRITERS

I'm writing a Mesa plugin right now.  It's finished, just needing to be tested out on a real machine.  I'm building up a Mini-Mill to test with.  7i43 USB board with analog daughter cards to control analog Yaskawa servo drives.

Galil / Re: Where to get 100 pin cable?

100 pin cable: http://cyberresearchuniversity.net/store/cables-wiring/pc-computer-cables/scsi-cables/CBSCSI_10003_4229.2.htm

That's the 3ft. cable.  They also have 6 and 9 ft. cables.

This is cheaper than going the Galil 2900 ICM route, but you will have to forgo the opto-isolation option and HI/LOW amp enable features that the Galil ICM provides.

Galil / Re: Galil + G31+ Mach3
« on: October 09, 2009, 08:39:50 PM »
Yes, the plugin on the download page is what you need.  As I fix problems, I put it out there so that new users get the most current plugin. 

Yes, all of the latch inputs of the moving axes.  "G31 X10 Y5 Z0" is perfectly legal Gcode.  So you would want to capture the positions of all of the axes if the probe hit!  This also makes probing to a file work as you will get XYZ records for a point cloud.  Just hooking up the Z latch would only give you a Z point.

Get the newest plugin off of the download page.  Then you have to connect all of the latch inputs of any Mach defined axes.  All of them.  If you run XYZ, then Xlatch, Ylatch, and Zlatch should be used.  If you are only moving X and Y, then Xlatch and Ylatch should be wired.  You loose these latch inputs as general inputs, but it's the only way to reliably probe with the Galil.
