More Mendel Problems

The problems continue... The new hot end parts arrived, and were fine, but i couldn't get the old heater resistor out of the heater block. So i ordered a new cartridge heater, which is the replacement for the resistor. I fitted that this morning and wired it up. heating up the hot end, I saw the temperature reach 150C or so then drop back. Measuring the cartridge heater found it to be 350k, so essentially open circuit. I'll have to get a replacement...

Looks like the new Duet electronics that are on the Fisher printer can be retro fitted to the mendel, so I'll see how that goes and maybe do a retro fit later. That'll solve the problems I'm having installing host software on older hardware.

Mendel Problems

The problems with the 3D printer continue. After yet another overheating problem the filament just won't come out of the hot end properly. I've ordered some replacement hot end parts so will try that. I'll then examine the ones that don't work very well.
Maybe it's old damp filament?
