      @andywm said in Deliberately slowing down heater warm-up:

      I'd do what @jens55 suggested - oh wait, I already have! (although I chose a DC UPS).

      and

      That is to say, run the bed from the mains and the rest of the printer from the UPS. That way, in the event of a power outage, the UPS will keep the printer running for much longer because the bed has by far the biggest current draw. And it'll take some time for the bed to cool.

      I'd also fit a thermal cut-out if the bed doesn't have one (although if it was me, I wouldn't use a bed heater that is so over powered).

      @phaedrux said in A Bed Leveling Quandary:
      In my case - even linear guides can be bent ☹

      My heightmap looked the same as the last picture.

      I first had to screw my x-axis tight in the middle, then attach it to the outside with a hair-ruler with a slight bend against the delay - the rest is done by mbc (mesh bed comp.)

      That would be direct from the shop on this site. I'll wait until you're all back in hours on the 2nd.

      I've not quite got it to print yet, I hit the stop after about 20 seconds, but with your settings MarMed I didn't notice any violent lurching like before. So within any luck… That's that sorted.

      Did notice something now that grinding is gone, there is another grinding from the extruder stepper. The stepper can't seem overcome the pressure holding the fillament in place from the feeding mechanism without having an external force assist it from above. So... I probably have that a little too tight.... So the extruder issue was mechanical after all. (my extruder mechanism is new to me, I bought a Flexion kit along side the Duet. Probably should have taken one thing at a time.)
