GT2560 rev B Spare controller card

[Mikael_Moran]

Hi!

Where can i buy an extra controller card, GT2560 Rev B ? Mine has burned suddenly ? Or can i use the GT2560 Rev A card ?

Normal，the mainboard works well, the motherboard does not appear burned, you should first check your power supply and cable is normal.
If you need to replace the motherboard, you need to tell me your model at first.

Hi.

Sorry i forgot to post the model of my printer, it is a Mecreator 2

The cables look fine, no short as i can messure, same as for the voltage from the power supply. I think all started with the y-driver board that get overheated, and burned, and then that short, burned the motherboard. I checked the stepper, and it works fine.

Attached a picture of the board.

The motherboard seems to be burned down because of a short circuit on driver board A4988

I was on my way to try a new driver, but then i saw that the motherboard also was burned, so i newer did that. It happened under a print. I have newer encountered any problems before that.

OK.You should contact the related sales staff and let them send you a new board.
By the way,you should also ensure the driver board A4988 works well before printing.(Test the voltage of A4988 before you start printing,normal is 0.8-1.2V)
