@gloomyandy Fair Enough. It may be a few days before I'll have access to the printer again, but I'll be sure to post a video when I do.
Also, we have been using the BLTouch to collect a "control" mesh, but since then the physical bed has been adjusted, so we'll have to do it again. Initially however, it seemed the SZP's results were pretty far off the BLTouch. I wonder if that is solely because of the PEI over the top of the steel sheet. There has been discussions that we may try to replace the printer bed to a more compatable material.
We'll also try the shorter cable as well as finding a better mount for the sensor board. cleaning up the wiring might prove difficult as it wasn't our team that did the wiring in the first place. so I'll leave it as a last resort.
Thank you for your help!
