Galil / Re: Galil 2133 or DSPMC/IP Motion Controller?
« on: April 24, 2010, 02:43:14 PM »
E-stop should be wired to the Galil ICM "abort" signal.  Mach will detect E-stop through the plugin. 

For a VFD type spindle drive, the plugin uses the Galil OF command (offset) to "adjust" the offset of the voltage on the analog output from 0 to 9.998 volts.  The plugin only controls the analog output voltage.  The rest of the required outputs (spindle on, clockwise, counterclockwise, etc...) are setup in Mach and are routed through the Galil plugin (if desired) as normal output signals.  The plugin operates this way IF the check box for an encoder on the spindle is NOT checked.

Mach does not send Galil commands.  The Plugin does.  Mach does not read the data record either.  That is also a plugin function.  It is the plugin's job to read the Galil data record and report the information back to mach.  Conversely, Mach tells the plugin what it wants output and the plugin's job is to make it so via the Galil commands.

Enable debugging in the plugin and a GalilDebug.txt file will be created.  You will see all of the Galil commands that the plugin sends to the controller.

Sounds like you don't have the FTDI drivers installed.  You need the one from their website and not the one that comes with Windows.

If you select "new topic", it starts a topic in the forum.  In this case, the Galil forum.  This will let you start your own topic.  You need to be where the list of topics are to do this (up a level).  Meaning not inside a topic like here.  But if you are reading a topic (like this one), either the quick reply or the "reply" button will let you post

No, not at all.  Put it up on the download page if you want. 

The USB version seems to work best.  The UDP on the Ethernet version can get hung up occasionally on a crowded network.

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
« on: January 05, 2010, 11:11:03 PM »
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)
« on: December 07, 2009, 10:39:53 PM »
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.
