So this works fine on my UpBox+. But got a cheap 2ndhand Upbox and when i run Gcode through it, the bed temperature gets to the target so 65deg say then jumps to 70 odd then back to 64/65 deg. This is all via an M190 S65 command in gcode. But it never triggers that it has got to temperature and to carry on with executing the rest of the gcode. M140 commands seem to do nothing.
Took the back off and the bed cable was slightly want seated with one end out by 3 mm or so… Thought that might fix it but no…
Anyone any ideas?
Manual bd heating gets to about 80deg c then can jump up to 93deg c then back to 80. Never gets to ABS temps needed.i.e. 110
Note this is all with the latest up studio. I might drop back a few versions see if that helps.
