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,...

Green indicates that the circuit is closed. So if the driver's Alarm signal is set to normally closed, the indicator should be green until an alarm is triggered. So, why is the PLC diagnostic showing it as red, regardless of the setting for the alarm output on the driver (NC or NO)? Also, the behavi...

First, I'm running 5.08 still - I will be upgrading to the 5.1 beta soon, but I just want to get the basics working first. I tested the X and Z stepper motors for my lathe individually on the bench and they worked fine. That was about a month ago. I now have everything wired up in the machine, but I...

Yes. They say the only way to do it is with the voltage->PWM converter, either the one they sell or another. But others have wired it directly into the Acorn's DB25 connector, with success. Since I have a voltage to PWM converter board that meets Teknic's specs I'll probably cram that into the box a...

I'm using a Teknic MCPV motor for a lathe spindle. I also have an MCVC but I think they're functionally equivalent for my purposes. This is not the same as an SDSK motor that takes pulse and direction signals. I have read through this thread at least 5 times: https://centroidcncforum.com/viewtopic.p...

great info, once finalized, please post latest working configurations and maybe a video demo. and i will gather and compile info into a Tech Bulletin and create a centroid schematic for others to use in the future. Was a tech bulletin on this ever made? I could only find one for SDSK motors. Trying...

This was my (pre-caffeinated) thought. So does that mean I don't need the resistor at all in this case? If so, would I be better off wiring it like they outline, so that the LED power is controlled by the button, or would it be better to wire the LED directly to the USB-BOB's 5V and COM, and then tu...

Ok, another wiring question: the cheap latching buttons I have (which I already have and want to use) have integrated LEDs that can either be always on, or can light when pressed. I want them to show the state of the button, because these are low profile and there's not much travel in the button - i...
