Centroid Community CNC Support Forum

Outputs on the CNC are not switched by an relay, they are switched with the software and can switch an relay. You like to make simple things complicate...😉 It's not about making things complicated - I didn't think I had enough wire to the motor (which has a custom cable I had cut short to reach the...

I just pulled 24V from the acorn into the relay NO terminal and I'm feeding that to the motor. It's all up and running now. Had to rejigger a bunch of my wiring to get it to reach the relay board but it's working: https://www.youtube.com/watch?v=dhT1MtVoKG4 Yes, I'm aware of how bad that pulley is. ...

I agree with not wanting to deal with the PLC stuff right now, especially since I'm still coming up to speed on Acorn as a whole. However, the wiring was cut to fit the distance to the Acorn board, not the relay board, so this poses some challenges. I may be able to flip the relay board so the relay...

Confirmed with Teknic that I need the enable pin set up for this because it is disabled by default on startup. The software enable in the MSP software ignored hardware input when being used.

so then Outputs 1-4 (relays) and DB25 pins 1, 14, 16, 17 are always linked together? It seems to be this way, testing with a voltage tester. I wired up the enable and direction pins to the DB25 breakout, but the behavior is the opposite of what I'd expect: The Teknic motor is coming up enabled by de...

I need to send 5-24V signals to the Direction and Enable pins on a Teknic Clearpath motor. Looking at the wizard, the only thing I can find that looks right is VFDDirection and VFDEnable. I don't have a VFD but this seems like the functional equivalent. If I assign VFDEnable to an output in the wiza...

I have an email in to Teknic support, but I'm hoping someone here might know. I'm sure I'm missing something simple. Motor is CPM-MCPV-2311S-ELN and I'm controlling it from an Acorn. This is the spindle for my micro-lathe. Acorn outputs 0-10V, but the motor requires PWM input. I am running the 0-10V...

Ok, I got this working. It was, um, operator error. Basically, after bench testing I made up some DB9 connectors that will live underneath the slant bed for the lathe (it's a small Sherline lathe) so that I can easily remove it if I ever need to. I screwed up the wiring in one end of the DB9 connect...

Here's a report, if that helps.

Ahh. Thanks. Ok so I swapped the ALM +/- wires and now it's coming up with the correct lights on PLC diags and on the board. One problem solved. The home switches were already wired correctly, I shouldn't have included it in the list of things connected to +24V in OP, as that was incorrect. However,...
