Hi,

did you rename your compiled script to extension *.lua?
When you look at the samples from scripting manual then the package path contains only patterns with ?.lua

I just received this drive and have found that the problem is with the fact  that these controllers will only control 3 drives at once.. X/Y/Z, X/A/Z but, not 4 physical axis can be used.. Sad I do not believe there is an adjustment or fix that can be done..  *sorry*..

45a @140v seems high. Is that the old drive spec or from the motor?
Don

The existing drives are rated 30A.  The constant stall current is 11.3A, peak 65A.  The machine can do 400 IPM rapids.  Coming to a stop from that speed can blow a drive.  The existing drives are Servo Dynamics.  They sell for $1400 each.

Sparky3i,
I am now back to cutting the medallion.
This cut in to finish what stopped 2 weeks ago.
its a 7+ hour cut and it still cutting past the 4 hour mark.
I am using v63 on this cut with V3383.
We only have Steppers with no feedback so you differ with your servos.
I have tried to use steps of .0025mm (2 Pulses exact) = .0001" and it seems to be OK, but reverted back to .01mm (8 Pulses exact) good enough for our hobby mill.
You might want to manually calculate the pulses, do you get an even number Steps Per X your Step Distance.
Thanks to Rufi hard work all is looking good, I will be testing V3390 as he has posted the Plugins.
Regards,
Mauri.

My motors are electro craft e703. The motor spec says max peak 45a but max cont 9.6a. The old drives were 15a fets. They run fine with these. Of course my machine is smaller around 3500 lbs.

So far pretty easy. I am only running motor encoders now and plan to add the linears later. I like the limits going thru the drives to allow easy use of the encoder's index for homing. 45a @140v seems high. Is that the old drive spec or from the motor?

Thanks for the heads up.  The amps might be a little low for my motors.  I sent them a question to see if there drive can run my motors. 
How easy was it to tune the drives?  I had a heck of a time with Gecko servo drives.

Hi,
either. Ethernet is fastest and has better latency performance. Ethernet is transformer isolated as
standard, USB can be isolated but need to be specified. Whether galvanic isolation is important is
a moot point.

I would recommend that if you buy one that you get one that has a Mach4 ready plugin in addition to
a Mach3 plugin. At this time the manufacturers whom offer cheap ($100-$200) Mach4 ready external
controllers are Warp9,PMDX, PoKeys and CNCdrive. All of these companies have been around a while
and all enjoy a good rep for backup. You need to read and interpret the specs and weigh those against
your requirements/expectations to make a choice. The good news is that any of them are pretty damn
good. Avoid the cheap-no-name stuff, the forum is littered with posts of people trying to get these
pieces of junk running.

I am trying to put 4 arcs on my piece of 1" x .625" OD brass round. I have no idea how to use this wizard. Does anyone know how?

I have been playing around with machdrives and like them so far. The have dual encoder support. David over there is one of the greatest in customer support.
