IGood ideas. I had originally thought about tape but the screen brackets are there to stiffen up the front so wanted a more rigid joint. Although with that much tape it would probably be ok..
Maybe I should do some tests on some tape.

I do the orient at 200 RPM. Or maybe 100. The spindle turns smoothly. I tried adding extra time to make sure it was turning at a stable speed. The key thing here is how it zeros exactly 90, 180, 270 degrees from where it should sometimes. I didnt even go any further with it. I know the signals are ok and I know centroid wont help so I sucked it up and replaced the VFD with a C2000 that will do the orient itself.cncsnw wrote: ↑Tue Nov 02, 2021 1:36 pmDoes the problem only show up when the spindle has been running at comparatively high speed?ashesman wrote:After a fair bit of testing, I am pretty sure there is something gammy in Centroids spindle encoder zeroing function M150.
Try adding logic that ensures the spindle speed is below around 2000 RPM before you call M150.
Another option would be to plug weld them from the back.
I did plug weld all the others from the back with TIG. The mark on the outside is minimal but still probably noticable. I was hoping to powder coat it so can't use any fillers on the outside. I also can't get down the sides of the screen to weld unfortunately.tblough wrote: ↑Tue Nov 02, 2021 7:31 pmAnother option would be to plug weld them from the back.
In my single experience with this so far, ferrites on the HDMI cable did not help, but ferrites on the spindle motor power wires (just below the VFD) did help.First the screen is not 100% happy when the spindle is running. Occasionally it loses signal from the PC for a few seconds. A bit of interference going on on the HDMI cable I guess. It wasn't a problem until the screen was in the control panel. Time for some extra earth wires and ferrites on the cables.
Good tip. I will go to town with the ferries! Unfortunately there is a few meters of HDMI cable running alongside all the motor cables as there is only one way to get cables out of the cabinet.
