Remora - ethernet NVEM / EC300 / EC500 cnc board

Hmm, the Remora step generator is blind to any scaling. It just receives a step frequency command from LinuxCNC (Remora component). So I'd be thinking somthing to do with the trajectory, axis and joint configuration.

Hi Scott,
Thank you for looking at this redundant joint/axis aspect.
I'm using two EC300s, updating one to the latest working status and holding the other as a back-up, in case I need to revert.  I will try again, deleting the redundant axes when flipping the EC300s next (I need to get the spindle trigger wheel signals working, index + 60 tooth).

Is there someone who can give me a answer on this questions? Thanks a lot in advance.

Hello, I have HLTNC AC Servos and would like to use them with the EC500 on Remora. The question is, which config can I use as a base for this? (Is it the closed loop config?)  Unfortunately, I can't find any information on this and would be very grateful if you could help me out or give me a tip.Here is the link to the motors used (z comes with a brake) and the link to the manual.

 Thank you very much in advance.

    

I'm going to get a ABZ encoder for the spindle. I'll jumper the pins straight to the IC, bypassing the optocouplers and run from an aud1200 as rbobey1989 has explained in previous posts. would a cheap encoder from AliExpress like the one in the link be ok ? 600ppr or 1000ppr? (Max spindle speed 3000rpm)

Is there an update to get the NVMPG working on the EC500 with remora?

The drive manual shows pulse and direction inputs, so it should be able to work with an EC500. 

NVMPG is working on the EC300 and EC500.

Hi, I'm currently trying to get the NVMPG up and running.

Which nvmpg.c file should be used for the EC500 CPP firmware?I have been trying with this version, but I only get error messages when I attempt to compile it using
When I start LinuxCNC, I receive an error message stating that the nvmpg.so file is not found in /usr/lib/linuxcnc/modules/.
