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, is there still a need to buy the relay board?
Update: I cut the cable from the VFD to the BOB at the BOB end and ran the program. I got the fault in under 2 minutes. Too bad, that sure would have been a nice fix.
Thanks,
Rick
What does "CUT" the cable from VFD to BOB mean.
Did you UNPLUG THE DB25 from Acorn and run the program?
Marty
Marty,
I literally cut the cable at the BOB with my dykes.
Maybe I misunderstood your intent wrt unplugging the DB25. It was my understanding that you were looking to see if any other faults appeared. Since I don't get any faults while running the program if the VFD is off, I figured there was nothing to see.
Rick
Earlier in your thread you said the spindle was off and you still got a fault. I asked for clarification. Was the VFD off as well or just the spindle not commanded to run.....
UNPLUG the DB 25 cable. Just run the Acorn and CNC12 in bench test mode. Run your program WITHOUT that Mach3 breakout board attached. (do not use that breakout board any longer with Acorn)
I would never CUT a cable, disconnect it maybe...
In a nutshell, get rid of that breakout board. With only your Acorn and the Estop button wired to Acorn itself (usually input 8 is assigned) run the program and see if you get a fault. You might read the Acorn installation manual and start from scratch. The manual is relatively new. It will walk you through benchtesting, testing the spindle output, basically confirming that the CNCPC and CNC12 are OK. Then using the schematic I posted, start wiring your acorn to one stepper driver and one motor and get them moving. Then add the second and third drives and motors. Then add your home switches. Testing things along the way and watching your error logs.
Using the DB25 for your drives and Acorn for your inputs and outputs is the way to go moving forward. (Order that relay, it is inexpensive. Provide +24VDC to in and then wiring each relay's terminal to each output on Acorn. Acorn SINKS the voltage to turn on the relay.
