Disabling heater timeout.
I came across the guide "Starting out tips for the Palette 3 Pro". I had previously been using my P3Pro with my Tronxy Crux 1 but wasn't getting consistent results. Finding the guide and seeing that the Mini is "officially" recognized by the P3Pro I decided to give it a try. sometimes a direct drive isn't always the best and greatest.Anyhoo, after setting up my printer according to the guide and setting up P2PP in PrusaSlicer I gave it a whirl. My results were pretty darn good.
UP until the last 45 mins of the print. I had fallen asleep so I wasn't near the printer when the P3Pro started chewing on the end of the filament in input 1 and it was complaining that the filament had run out and paused the print. Unfortunately the Mini had shut down the heaters. Normally this would be ok, but the bed cooled and after about 10 minutes into the resumed print, the purge block broke free of the bed. OK, I guess I could babysit the last 30 minutes or so, but then the main print came unstuck shortly after. So for a print that was I would say about 98% consistent with the result I was going for ended up failing with about a half hour left. :-(The only adjustments to make it "perfect" was to change my Load Offset by a couple of millimeters. I couldn't find the stock 57cm tube so I cut one of the longer ones down. With my tremor and older eyes I was off by a couple mm. No biggie, just a few stray color runs in the print.
It was the auto timeout of the heaters that really did the print in. When the bed cools the print obviously can be easily pulled free. Is there a way to disable the timeout? Maybe just on the bed so there is at least some still safety on the hotend to prevent a fire?
RE: Disabling heater timeout.
How long was it out of filament for?
I have a stock MINI+ with filament sensor. My filament ran out on an 18 hour print. Normally, when this happens, it pauses, beeps, and keeps the heaters on, both hotend and bed. However, in this case, it ran out sometime during the day, and it was probably around 5 hours before I got back to a message stating that due to inactivity, the hotend heater had been disabled. But the bed heater was still running, and the bed was being maintained at the printing temp.
I acknowledged the message, the hotend heated back up, I inserted new filament, it purged, then resumed printing. My print finished with zero issues.
RE:
This "feature" just blows! Do you know how annyoing it is when you have a 22+ hour print fail at %80 becasue you didn't catch the filament chanmge within the 30minutes? The print ultimately fails now becasue the bed cooled and the part came loose from the bed and moves around under the head.
So much wasted filament just cant be ignored these days with costs the way they are! I can understand timing out the hotend, but the bed?
Is this becasue I am running through a mosaic palette pro 3? A spool bound and didn't feed at the PP3, but the Prusa Mini still had filament in it's extruder.
