LinuxCNC-RIO - RealtimeIO for LinuxCNC based on FPGA (ICE40 / ECP5)

I'll have a go at a fresh pull, or git checkout your updated work. I'm so worried to over-write anything though, not because I doubt any of you beyond incredible talent and knowledge, but because the existing version I've rooted for is flawless. Spi W5500 + gowin that is. I actually made quite a few parts before leaving, Nothing to regret having jumped in!!

Always good to keep updated and in the loop anyway, so I'll do that. You sound good man, good vibes, Keep it up!

Gitano's creativity is great. Doesn't look Cult'ish enough though, he needs a tattoo + blink one of his eye and it's sorted

I finally gave up. I have spend hours and hours trying to find out why my motor stall. I even contacted the manufacture of the drives and motors with no success. I replaced all wires,motors, drives, added ferrite cores,.... There is almost nothing I have not tested.

I am convinced it has nothing to do with the Rio software. But the tang vs parallel port makes the difference. The signal after the BOB comes out with less noise when I run it from the parallel port as when I have the tang connected. I don't know why and I don't know why my DM332T don't make an issue either way, but the Microkinetics does.

I will order a new drive, but that opens up a new can of worms and I may upgrade directly to servo drives...

Hi, I'm not to familiar with the background of your issues (from a quick glance there's a hundred posts to decipher, it's overwhelming), but have you posted a concise and consolidated schematic, wiring installation and pictures of your entire set-up here or anywhere else?

Without that I highly doubt anyone (here at least) will be able to remotely assist. Although the noise issue you seem to be having has nothing to do with RIO let alone Linux CNC.

Ruling out RIO and Lcnc is easy, outputs can easily be probed while running a simple gcode program.

If I'd have to do it all over again I'd start with that incredibly simple yet super powerful starter kit. github.com/multigcs/rio-tangbob

So damn simple, and simplicity RULES. Not much can go wrong here.

Yeah, you are probably right. But I think even then remote troubleshooting is pretty difficult. I may open up another thread in the forum. But right now I need a break and look for something else. Still need to get Modbus working for my spindle. Will be starting with that soon.

I changed the Y Axis motors back to the Nema 23 with the DM332T driver. 3200 Microsteps/rpm and I can go up to 6000mm/min without an issue.
Handwheel xhc-whb04b-6 is working as well.

Now I am focusing on getting Modbus and the spindle to work. This is the last thing I need to run the mill with the Tang. Can someone confirm that this wiring is correct for the Max485?
