Tool failed during print

Phaedrux

@jumpedwithbothfeet said in Tool failed during print:

MCU temperature: min 37.5C, current 87.2C, max 87.4C

That is pretty toasty. Is this an enclosed printer?

jumpedwithbothfeet

@Phaedrux yes it is but only passively heated, water cooled hot end, Im trying to figure out a way of water cooling the board as a fan won’t cut it! And I’m guessing the board rear side is where the heat gets transferred like the main board?

jumpedwithbothfeet

Update, found a crimp that had gone bad on the part cooling fan (ground side) this maybe partly to blame, but doesn’t solve the hot cpu issue, could it cause the memory issue?

Phaedrux

does it still get hot like that without the bed heater and extruder heater going and the enclosure open?

jumpedwithbothfeet

@Phaedrux so essentially the printer turned on but not running a print? I’ve not tried it, I’ll turn it on and report back

@Phaedrux the temperature increased from 23.3 degrees to 31.4 over an hour.

I guess that eliminates a failed component getting hot and cooking the rest of it. The driver chip and it's supporting electronics would be the main source of heat on the board.

Can you try running a print without the enclosure sealed to see if it stays cooler/lasts longer?

jumpedwithbothfeet

@Phaedrux I’ve just run a 1hr print door wide open the MCU crept up consistently during the print it was 25 degrees at the start, 68.5 just before finishing so it’s getting warm, I’ll sort out a 2 hour print tomorrow to see if it continues to climb or plateaus again with the door open.

@Phaedrux just about to finish a 3 hour print, the temp with the door open reached 73.1 so still fairly toasty! I’m gonna try it again with the cable cover off see if it makes a difference….

No difference with the cover off!
