Too hot to handle
Good idea in principle and managed to physically assemble and get up to temperature. Yay!
Sadly there is a technical hitch...
190C melts solder.
The wires fell off.
There were sparks.
My hot end is cold again.
P.S. Ouch, fuck, bugger, ouch...

If you don't have crimps how do you make firebricks?ReplyDelete
Been there, done that. If you've got some terminal blocks sitting around, you can cut off the plastic covering and use the metal inner to connect wires to terminals in a non-heat-sensitive way.ReplyDelete
Or try some lead free solder it melts at a much higher temp.ReplyDelete
Tried that too. :-)ReplyDelete
Anyway, new hot end is working fine.
Latest issue is stepper controllers over heating when I try and print ABS.
