Remora - ethernet NVEM / EC300 / EC500 cnc board
Category: Computers and Hardware
Sure, when I did this, I uploaded the unmodified
nvem-full-config.txt
- from the Remora repo.
Reading the upload script, it looks like it makes a copy of what I feed into it and writes it to this config.txt file? Comparing the two documents showed them as identical.
Contents of the file to sense check:
Something else worth mentioning, I had read that the 4/5/6 axis boards used the same hardware, and that Remora doesn't care which version of the board you get. I bought a 4 axis version as the others were more expensive for seemingly no value add if used with Remora. I did use my multimeter and could trace the 5 and 6 axis step/dir pins back to what looks like a buffer IC at least. Hopefully I don't have some later version of the board that has additional locks in place.

Something else worth mentioning, I had read that the 4/5/6 axis boards used the same hardware, and that Remora doesn't care which version of the board you get. I bought a 4 axis version as the others were more expensive for seemingly no value add if used with Remora. I did use my multimeter and could trace the 5 and 6 axis step/dir pins back to what looks like a buffer IC at least. Hopefully I don't have some later version of the board that has additional locks in place.

In fact, with torque control, I don't think Linuxcnc is up to the task, you should choose OMRON..... PMAC controller.

Usually, the controller with a position closed-loop, the generation of following errors, and the PID controller of the upper computer, has little to do with it, because the position loop can be adjusted in the drive. At the same time, the following error = the maximum feed speed is proportional to the position loop gain

You should get the vendor's ethercat definition, which provides the scaling function....

Oh so those are now all in one file?
There were 3 back then, quick start, documentation and integrator's manual.
I recall thinking "how is this software under 5MB in size while documentation is nearly 30MB???"
Good times.
