Hi,

I somehow have troubles with my Linuxcnc setup. I use linuxcnc together with a NVEM Board with a RT1052 on it and the Remora-RT1052-cpp. When I do normal milling I usually don't see any problems. But with complex 3D surfaces all of the axis somehow drift away. It's not much but after 15 minutes of milling it's about 0.1mm. I'm quite sure that the problem are not the motors or the drivers. I also have the correct setup (setup and hold times) for my motordrivers, I even checked them with an oscilloscope and they are fine. With the oscilloscope I could also see, that the problem is not an EMI Problem, the signals (STEP/DIR) are not noisy at all.
Is it possible, that there is a problem with the Stepgenerator? I use the (almost) latest firmware 3.13 but from what I've seen the changes after 3.13 where not related to the Stepgenerator.
If not what else could cause this problem?

Thanks Clemens

Thank you very much for the firmware! It loaded to the board without problems. I will try it out.
