GTM32 Pro vb after Firmwareupdate Headbed and Hotend problem

Post by GeMo » Sat Sep 19, 2020 4:36 am

After updating firmware from my GTM32 PRO VB, Prusa I3 M201, from V1.0.01 to V1.0.04 I have some problems. By the way, the manuels to update bootloader and update firmeware are excellent and with the update itself with stsw-link I have no problems.
But now headbed and hotend are not working. I tried it via LCD und USB. LCD shows 0 0 after selecting PLA with 200° and headbed with 70°. Then I send the g code M109, but without success.
Then I disassembled hotend and headbed and stand alone they are working.
Then I downgrade back to V1.0.01 but now I have the same problems with this firmware.
What can I do?

The support of Geeetech told me, that a thermistor on the motherboard has get an error by flashing process. Witch thermistor could it be? Can I solder a new one? I do not know, where I can get a similar new board (GTM32 Pro VB).
Can anyone help me?
