Ya it's entirely random where it goes though, and I've had it happen, then reset the printer and restart the gcode and have it print without it doing this.Tim wrote:It sounds more like deliberate behavior. The Z-probe, like any endstop switch, is only active at certain times, which doesn't include during printing. The endstops aren't even checked during printing; if they were to report false positives, nothing would happen. For probing, the Z-probe does its thing, saves the results, and then the rest is just doing calculations based on the Z-probe results and does not involve the Z-probe itself any more. What you describe sounds more like the slicer has inserted some sort of action for a nozzle wipe or something. If it's in the g-code, then the travel points should show up in a g-code previewer.goopyplastic wrote:I noticed some weird behavior on my machine. It will auto probe, then while printing the nozzle will go off randomly to different spots on the bed far away from the print somewhat slowly, then it drifts back to where it started and keep on printing. It will keep do this randomly it's pretty bizarre. I think it might be combination of bad sensor and running at 5v, going to order a replacement and try the voltage divider. Anyone else ever see anything like this?
I was thinking something like a flaky sensor might give it really weird probe results and the the computed plane might have a weird spike or something. I realize it's unlikely but probably worth trying. I'll post up the gcode see if someone notices anything, but the movements are not in the preview on s3d.
