matth added a comment to T8820: TAZ Pro - extruder not spinning.

I repeated it several times July 17th, then of course it doesn't repeat when I brought it in today. While it was repeating for nozzle 1, it may have been occurring for nozzle 2 as well. In T8648, I mentioned how I was repeatedly getting "Extruder x Filament Error" messages prior to the heat runaway. At every error, I would confirm it wasn't stripping out and indeed extruding correctly, yet would still give the error when resumed. When I would disable the runout sensor and resume the print, it would complete the print without extruding from that nozzle for the rest of the print.

I made it in freecad, with a height to make it need 2 layers. In cura, I load it in twice and have each nozzle print each one. Been using it since alpha to determine z-offset height.

The idler tension would not be intentional. That would be my bad, probably from when I had to dismantle the tool head in order to remove filament that had broken off and couldn't be extruded out. That may explain my true positives with extruder 1, but obviously not the false positives with extruder 2.

I've been getting a lot of filament runout errors lately, and I know it's because of the filament reels. I have a different machine (a current beta) and am still running into this error. Each time it's because a reel is caught or conflicting with something; the filament is super taught and would be stripping in the tool head if I resumed it. Each time I fixed the error by unreeling some filament to create some slack.

Maybe it's just personal preference, but when I load in filament, I prefer to use the "change filament" menu to preheat the nozzle and have it auto-extrude until I'm satisfied with the extrusion. It's also easier to preheat to the desired temperature with a single button press.

For my machine, firmware 77 made it a lot worse. I've run the calibration more than 10 times in a row and have been getting very inconsistent results for the z offset. My min and max values so far have been -0.29 and 1.32, and even if I dismiss the extreme outliers I still have a very wide range of results, which then would require more testing to find the ideal z offset.

I'd also like to add that Jeff and I have gotten very different results from running the calibration test multiple times. While the x and y offsets are fairly consistent, the z offset has a much bigger range. One calibration put the z offset at 0.24 and produced some poor prints, while another calibration put it at -0.01 and produced far better prints. Running the calibration multiple times in row, making sure the nozzles are clean each time, produces a wide range of z offset measurements.
