Sounds like it could be caused by an electrical noise issue.

Relays can produce current surge and voltage spikes also the contacts can arc producing electrical noise.
VFD's if not properly connected and the cabling shielded produce wide band noise from DC right up into the RF spectrum.

Are you using a relay or VFD for your spindle control ?

Rusty,

I agree with Hood, swap your axis so that your rotary becomes Axis A (4). This way you can easily zero the rotary and check it's position or view the program limits etc.

Klaus is very modest about his excellent programs. 

Here is the link to MachProfile and other useful programs  http://www.kd-dietz.de/index_eng.htm

Hope that doesn't have any subliminal meaning (like the WD40 perhaps) this is a family forum.

Do you have any other suggestions for why the driver test doesn't run then ?

Jeff is quite right, we are all over the place but we are all joined up with little wires and communicate with each other just like a breakout board and set of gecko's. 

Seriously though Eric, we are all here to help you, just ask away.

Generally if the driver test does not run then the drivers are not installed. Try downloading the latest version of Mach and re-installing, this should solve your problem.

Mark,

Not many people seem to be using Mach3 for foam cutting so there is not much of an information database. This thread may be of interest to follow http://www.machsupport.com/forum/index.php/topic,15968.0.html

Show"N"Tell ( Your Machines) / Re: The Laser Project.

« on: December 06, 2010, 05:46:43 AM »

Ntlaser,

Mach3 will output a PWM signal which is linked to the spindle speed setting and I have found it is easiest to configure it so that S100=10% power and S1000=100% power then just add the appropriate S commands to your program as required. Your laser will have to automatically insert the 'tickle' pulses as necessary because these are not sent out by Mach3. You will also have to incorporate a method of switching the laser on/off and various methods are available.
Personally I prefer manual control of the power setting but I intend to incorporate auto/manual into the controller I am currently working on and keep all my options open.

What is the make and model of your machine ?
