Galil / Re: Which Galil to use??
« on: December 18, 2012, 05:39:47 PM »
If the drives will accept +-10v command signals or Step and Dir signals, any of the recent Galils will work.  I like to stick with the Ethernet controllers.  21x3, 41x3, 21x0, 22x0, 40x0, etc...  Just get on with enough axes to run your machine + one more to drive your spindle (if you so desire).


Galil / Re: Upgraded to win7 on PCI system - now weird VFD behavior

Wow...  That is a weird one!

All the check box does is control whether or not to use a JG command or an OF to run the spindle.  It does no other magic.  

I assume that your spindle does not use an encoder.  If that is the case, then the KP, KI, and KD parameters for the axis driving the spindle all need to be set to 0 and burned with the BN command.  Otherwise, you need to have proper PID values to use an encoder.

Maybe your previous card had the PID set to zero and you new one doesn't.  That is the only thing I can come up with.

Check and see if you can increase your Ethernet card's transmit buffers.  A lot of the new computers are coming out with cheesy settings on the transmit side (Expecting more downloads than uploads, apparently).  I had the same thing happen on my D2700 Atom board.  Also, make sure that "Interrupt Moderation" is turned off, if you have such a setting. 

Simply put, what you are experiencing is simply not being able to send data to the Galil fast enough.

Yeah, I'll second the vote for the 2160.  Both controllers use the 100pin cable.  But the PCI 1842 card will need a much LONGER cable than the 2160.  Also, with the 2160, you don't have to worry about special drivers.  I'm just a big fan of the Ethernet controllers.

Sounds like the encoder on your Y motor is wired backwards.  Swap the A & B signals and see if it holds.

You have it correct.  Map Mach Output 1 and 2 signals to Galil Output 1 and 2 in ports and pins.  Then use MODCMD and SGND as your 0 to 10v reference.  Then check the "Spindle is 0 to 10v" in the Galil plugin config.

For disabling the drives, I would wire the Galil AMPEN circuit to operate a Solid State Relay.  Shunt the AMC disable circuit to ground through the output side of the SSR.

You will have to configure the plugin to match your AB system.  One thing you can do it fire up Camsoft and then go into a Galil terminal to see what all it sets up on the Galil.  PID values (KP, KI, KD), motor types (MT), etc...  One other important thing to take note is the CN value.  Then configure the plugin to match those values by firing up Mach and going into the terminal to see what the settings did.

Unfortunately, the gantry homing is not working correctly at this time.  So you are not alone.  :(  The problem is that neither Kenny nor I have a gantry machine to test on to get it working.


Galil / Re: Galil I/O Questions (17xx/18xx)

1.  For swapping the amp enable from high to low or vice verse, take a look at: http://www.galilmc.com/support/appnotes/optima/note1415.pdf
2.  You have 8 uncommitted outputs on your 1740.  Outputs #1-8.  Just map the mach mist signal to one of those pins in "ports and pins".  No matter what voltage you choose on the outputs (depends if they are opto isolated on your ICM), I would use it to drive a solid state relay to control your pump circuit.
3.  Wire your estop to to the Galil Abort input.  See the docs on your ICM and controller for how it should be wired.
4.  This depends on your servo amps.  If the have an an enable circuit, then wiring them to the amp enable outputs on the Galil would be sufficient.  The plugin sends SH to enable the amps and MO to disable the amps.  However, you may want to wire a contactor into your estop circuit to kill main power when in estop.  
5.  Yes.  Limits for homes is possible.
6.  The aux encoder inputs are just for the A and B encoder signals.  Hooking up just a plain encoder is pretty easy.  However, if you are using one of the available MPG pendants that have an axis choice switch and an increment selector, then there is a little more to it.  The encoder signals go to the same pins on the aux encoder input, but you will need to route the selector switches to inputs (and you only have 8).  Then you have to write a brain to take those inputs and tickle mach the right way.  It gets complicated.  :(
