General Mach Discussion / Table crashed now motor runs full speed. What to troubleshoot next?

« on: June 26, 2016, 05:50:46 PM »

The table crashed. I think it might have been what caused the issue. Anyway now the X axis motor runs full speed ahead. The Y table moves just fine, but X rapids absolutely insanely fast and does not stop if i let go of jog. Even a single "step" and it takes off.

I've made sure I was in inches units, I double checked and changed acceleration and velocity settings and tried turning them down. It works but it still wont stop and eventually speeds up to same speed before I hit reset.

I've power cycled everything, the "DRO" is receiving feedback from the encoder on the motor so I don't think that's it I have no idea what to check next. Feedback on both of them is funny though it steps through "thousandths" instead of inches even though the steps per unit is correct and just worked the other day. The only think I can think of is it is a bad interface card?

Any help would be appreciated. Running mach3 demo, with a Galil 1820 driver and brushed servo motors.

Galil / Galil DMC 1820 Setup - Cannot figure out how to make motors move!

« on: June 15, 2016, 07:36:23 PM »

I've got a Galil DMC1820 motion controller and the computer that ran it before has died so I'm trying to get this thing setup in Mach3 on a new computer.

It's run into a ICM-1900 which breaks out all the controls and pushes it out to the XY table which is run by a MCG Brush type servo amplifier model DMC 12D.

When power is on the controller holds the servo position so that you cannot move it so I know everything is "wired" correctly, but no matter what I do with mach3 I can't figure out how to get anything to turn.

The Galil plugin has been used, the computer recognizes the PCI card, and Galil drivers are installed. The card has been selected in Mach3, along with the index checkboxes. I do not know how to configure the motors as none of the "pins" are the same as in the ICM-1900. Most of the pins are in the ~80 range.

Any assistance would be appreciated. I'm running Mach3 on windows XP with the demo program. It is just controlling an XY table for a laser so I am using the plasma module.

Thanks!
