I think it's a matter of bin firmware. Scott has so far set the bin on about 3 axes. But then I don't think there will be a problem to add another 3 (it doesn't matter in the bin). I have a worse problem now. I have limit switches PNP / NC, tool sensor NC and 3D touch probe NPN / NO

Not far off Domi with the custom config ability. Then your problem will be solved

If it were a network issue LinuxCNC would go into E-Stop before triggering a following error. It's the way the communication logic works. Your following errors are most likely caused by your joint configuration. Your joint max velocity needs to he higher than the overall max velocity so that a joint can try to catch up the following error. Take a look at the example INI file. I've tuned that one to get some good speeds without ferrors.

 

I've tried about everything, 3 different pc's with low latency, a lot of different settings includings yours but still get the following errors at random moments. Tomorrow I'll try the lpt port to exlude the nvem or my config.
 

Right now I assume the different amount of axis just means more connected breakout pins. Is that correct?
The current firmware supports 6 axes (joints) and should run on the 3, 4 and 5 axis versions as they appear only to be limited by the original firmware and maybe the mystery chip. It would be interesting to find out if the 3 axis version has the same physical connections as a 6 axis. There is a $20 dollar difference for the same hardware maybe?

Alright then. I think I will go for the 5 axis one and hope for the best

Also buy a 6-axis version and take a picture of the chip you used (hardware on the motherboard). I think it will be the same. My opinion. I think it will be limited to software. I also have a 4axis board. And I don't think they would use two longer ones. But I don't care about firmware, so I can't confirm that.

I've tried with a bob on the lpt port and that works good, then tried the nvem again with the same settings and the following error appeared again. Even when I lower the velocity at half the speed. I can't imagine it would be that slow. Tried a different power supply already a 12v and a 15v, I assume that that would be enough. Is there anything else I could try? I was thinking about maybe I could to connect it by SPI to exclude the ethernet chip? Could I upload one of the other Remora firmwares to run some gcode without the steppers connected?

Please share your config files so that I can have a look. Thanks
