having some issues printing ABS
1. print bed takes forever to heat up. and actually doesn't hit target temp of 110c. mine maxed out at 107c. 95-110 is the suggested bed temp for ABS. my print was warped on the face that was attached to the print bed. it didn't lift the edges but the face has a slight radius
2. printer back to stopping during a print. With PLA i was able to ruin a 9+hour print. with no problems except running out of filament(obviously my fault). but with ABS its down to about 2 hours of printing then stops.
thinking the print stops is due to something over heating from the bed being maxed out. going to try it at 95 but still expecting a stoppage being so close to the max for the bed and the length of print
@Chris D, I've just gone through several ABS+ prints, with several failures (6-7). The print I did went for 4-5 hours and the best settings I've found are:
- Extruder @ 240 º C
- Heated Bed (new one) @ 80 º C
- Temperature offsets in Octoprint set to +/- 5 º C
- Miniature bulldog clips to hold the flexplate to the new bed (that things slippery)
Print stuck to the bed like glue. Sadly, when getting the prints off, the bed actually split while flexing. I'm guessing the high temps made the Print Surface sticker go brittle.
If you want the detailed version, see your other post: https://www.forum.makertech3d.com/forum/general-discussion/printing-stops
another issue that came up with the flex plate the the printing surface that adheres to the flex plate ended up with quite a few bumps. my guess is small air pockets they were all over the print surface. they were especially bad were the print was.
i had thought of the overheating controller or power supply. was trying to figure something that enclosed above the base but below the bed rails. haven't been able to come up with a quick and easy fix here. so it may take a little engineering. anything i can think of about triples the footprint of the printer. might be able to attach something to the bed rails but the larger mass would slow printing down for qualities sake. idk still mulling it over
Printer in an enclosure? ABS hates airflow and that causes warping, that would also allow the bed to get warmer. Always ran my ABS at bed temp of 80 previously, that’s as hot as my old printer would go, no warping. For that I just used a cardboard box. Not the safest thing to do, but for that printer the controller was separate and could be outside this box. At the bed temperature you’re going for and an enclosure, the built in controller may overheat.
