Is the "Reheat finished" dialog box confirmation necessary? I would prefer if it just immediately resumed printing.

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.

So @anolen witnessed the issue and was able to identify the problem and apply a fix. She'll be able to describe it better than I can, but from what I understand my errors came from a faulty wire for nozzle 2 in the tool head. I will test to confirm the fix, and then move on to testing big reels.

It seems to happen most often when the toolhead is on the right when it is z homed. If it were to home the x to the left before homing the z, I believe that would help prevent the issue. Perhaps not completely, but it would help

matth added a comment to T5813: Filament holder location change.

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.

I was thinking of a printed part that would attach to a top extrusion through which the tubes would be fed through. Similar to zip ties, just with a fixed location. I can try some ties for now.

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.

I've had this problem come back. I update to .91, so I factory reset and ran a few calibrations. Ran it over 10 times and have gotten results that are all over the place. Looking back on my notes, .88 produced good calibrations, so it's either the current firmware or my machine.

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.

matth added a comment to T5204: Inconsistent results - 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.
