Also, you still have probe tripped messages in your log file (F7 Utility, F9 Logs, F1 Errors) YOU DID DISCONNECT AND REMOVE IT FROM THE INPUTS CORRECT?

Marty, The Avanexpress DB25 Breakout Connectors should arrive tomorrow. Unfortunately, house guests arrive at the same time so it might be a few days before I can make the change. Since I have no plans to control my VFD from CNC12, I'll just remove the existing circuit. Without this functionality, i...

I would remove that opto board you have on the end of the DB25. Acorn takes care of this. Since there are 5 inputs on the DB25, you can have something coming back on the DB25 Replace with a standard DB25 breakout board like this: Avanexpress DB25 Breakout Connector D-sub Breakout 25 Pin Connector F...

Rick, Could you please just post a current picture of your control cabinet showing Acorn here. So you disconnected your home sensors and the fault still occurred? What is still connected to the inputs and outputs of Acorn? Could you please also post a current fresh report. What kind of drives are y...

I meant to say that I have only seen the fault when the spindle was on. Details of my hardware are at https://rick.sparber.org/ma.html#CNC. The VFD is optically connected to the breakout board which connects to the parallel port. I just disconnected my home sensors and turned off those inputs in Aco...

Yes. No joy.

Gary,

I believe so: https://rick.sparber.org/VFD_Noise_Reduction.pdf

At the present time, Centroid hardware does not control my VFD although paths are present. They are optically isolated.

Ah, so the 327 fault is not from the CNC12 program but from the PLC inside the Acorn. That helps narrow my search for the root cause. I have only seen this fault when the spindle motor is running. I unbolted the VFD from the wall and moved it as far away from the Acorn and PC as possible. None of it...

With the spindle motor off, I did not have any problems for about 150 lines of code. With the motor running and under load, I got the 327 fault again. I have attached a screen shot plus the latest Report. I then made the change that Marty suggested and it failed at line 43 with the same 327 fault. I...

Marty, I have tested the probe since installing 4.65. I had previously set Part 0 and then power cycled. Then I measured the location of part 0 wrt Home and it was off by 4 thou on the X axis, 8 thou on the Y axis and 5 thou on the Z axis. My home switches are magnetic proximity switches. Murphy is ...
