Re: Broken Thermistor killing the GT2560 V3.0 board

Hi, thks for the solution, but since I managed to fry 2 boards.... ...at the one board your solution might help, but on one board frying the chip did not only throw off the T0 readings but grounded T1, so I have a permanent -14°Celsius :) Ah and nice that you are showing the shematics.... they are w...

Re: Broken Thermistor killing the GT2560 V3.0 board

Hi, after a few days root cause analysis I found the reason: At some heater cartridges the wire insulation is not firm, moving to far and revealing the bare wire. If this wire touches the hotend, 24V voltage is applied to the hotend even when the extruder is not heating. No if the thermistor breaks ...

Re: What kind of nozzle is on A10M?

Hi, Be aware of two things: A10 and A10M using different nozzle types! A10 using M6 thread A10M using M7 thread (but not standard MK10!) take care which M7 nozzle you are buying!
