General Mach Discussion / X axis stopped working
« on: February 06, 2010, 01:14:02 PM »
I have been running Mach3 with Dell 800 for 3 months on a 4 axis machine. The X axis stopped working suddenly.

I have checked the LPT port motor output pins for voltage. Y, A, and B look the same. DIR 0-5V, Step 0-50mV. Y, A, and B work. X stopped working. DIR shows 0-5 v Step shows 80mv -130mv at the port pin. DRO moves but no motor movement.

I have verified the X axis wiring and motor are good on the other axis.

I have check the LPT port with a printer and it works.

The strange thing is if I swap the Step and Dir pins in the setup I get good voltage readings. (but my driver board can't use it like that).

Thoughts appreciated.

(I would like to get some sleep.)

Would you care to share how you use the pwm to control hot wire heat? I have a controller board without documentation. I have managed to get everything working but the pwm output.

I am unable to see the pwm out of the demo Mach 3. I am about to purchase Mach 3 but I would like to know that it will output pwm for heat control of a hot wire.



I'm new to Mach 3 and cnc in general. I'm building a CNC foam cutter.

Does the demo Mach 3 software output pwm? I have tried to set it up but don't see it. Everything else (motors, etc) are working great.
