Heat Runaway after switching extruder
Closed, ResolvedPublic


This is with firmware .144. Steps to reproduce:

  1. power on machine
  1. hit temperature, set both nozzles to 230 C
  1. before it gets to 230, hit menu -> change filament, then nozzle 2
  1. after a minute or so, it'll say it has a heat runaway and then reset. When it comes back nozzle 1 will be around 260.

So, seems that the printer will keep heating nozzle 1 with no limit while it is switched to nozzle 2. If you let it reach 230 before step 3, there won't be a runaway.

I haven't been able to reproduce this in .149, so may be already resolved.
