Remora - ethernet NVEM / EC300 / EC500 cnc board

I had two lines missing in the hal:
#spindle DAC 0-10 control

net spindle-cw remora.output.00
loadrt pwmgen output_type=1

output.00 is OT1 on the EC300 and if I'm not mistaken the EC500 and NVEM also.

I looked again at my config and i see some unnecessary crap so ignore this message

zelo, make your stepgen maxaccel higher than your regular max accel

Thanks for the hint, already did that but haven't updated repo yet.

I noticed that following joint error happens a lot when moving with encoder wheel on nvmpg even that gcode results in much higher speeds. For now I limited jog speed to 40mm/s.

Okay. I'm officially lost. I can't get the stepper motors to work normally. Everything else works or would work with a few configuration changes if the movement was resolved. With the ec300-rt1052.txt configuration, the steppers have the grinding sound you can hear in the linked video.



I disconnected the shaft coupler, it's not a mechanical problem and it occurs on all axes. Since I can't find an ec300 specific DMA configuration, I modified the ec500-rt1052-DMA.txt configuration and used the settings appropriate for the dm556 driver. There is no movement at all with this configuration.

BSOD on the video I see your shaft is moving on motor side. Tighten your motor - ball screw coupler.

Oh you did it on purpose. My ADHD kicked too fast .

I would check if your timings are properly set in remora config.txt for your driver. You can check my repo since I use similar one DM556T.
I would limit velocity and acceleration on all axis to small one like 10mm/s, reduce microstepping, and increase amperage rating. Basically make everything easy to decrease amount of reasons that it can fail.

Sometimes I get similar sound when the position is oscilating, but that's usually when it flips between two microsteps.
Does the grinding sound keep going when you home that axis?

Also ensure that your logic voltage level is set correctly on DM556 driver if it have switches for that. I know newer DM556T have one.
