Have you tried it ?? Do you have another PC to test with or another  lpt port ?

Can you check the PMW with a volt meter ??  The higher the % the higher the voltage ?

OK then Check the output voltage from the g540 to the controller while running IS it drooping as time passes or does it remain steady ?? IF drooping then check the out voltage from the controller to the G540. It is steady or drooping. If steady then the problem maybe G540 IF drooping it maybe the controller Power supply drooping under load. IF needed install an outside PS to power up the G540 VFD voltage input.  Wallwarts are cheap. Just make sure it has enough capacity so it does not droop.

Follow the voltage trail,

Can't you just follow the voltage level feeding the controller. Check the voltage level feeding the Controller. IF the voltage level is not constant follow it all the way back to the source.  What is feeding the logic to control the speed in teh G540 is it step/dir or PMW.  Check those levels coming out of Mach3 to the G540. I can't see that being able to droop to zero. (But never say never) The G540 just takes those values and converts to 0-+10 which is feed from the controller. The controller seems to be the culprit Check for a steady level voltage that feeds the G540 . IF the voltage level at that point is steady then it points to the G540 ?

You should not have to STOP in the middle of a job to adjust tool height. Get it all right from the start and it will do as told and be correct.

Each tool can be set for height offset in the tool table. Start with the longest tool as the Master tool. Set Master tool as ZERO tool height then offset all other tools from the master. When you start the job SET the master to the top of material as Z0.000. Then everything should work out fine. At tool change each tool will COMP itself with the (G43 Htool#) call.

Program the Machine to move to a spot out of the way then add M01 to the Gcode.  Mach3 will Wait untill you press the Cycle Start button again then resume running the Code.

Caution : this is a software PAUSE it does NOT mean the machine cannot restart on its own.

Also make sure the Hz is set correct for the motor and RPM.

It was ART and Scott (;-) With M4 still changing at the core level Don't count on it unless Scott wants to take a stab at it. HUM I remember more people working on it. Maybe it was the Xbox controller.

Goto Port & Pins then spindle setup. Bottom center .

You may want to talk with MachMotion about teh delays. Some are set to protect the VFD.  Some drives cannot take full reserval at full speed. It will blow the final out of it from BackEMF.

You need to remember that the Shuttle plugin was NOT written by artsoft. It was written by an individual who kindly donated to the Mach3 family.

If memory serves me, (;-)TP
