Fitted new mother board and heat mat and it does not print

Hello, first post!

I am quite new to 3D printers so please bear with me and my question.

I have a Reprap Mendel 3DP03 3D Printer.

A while ago the heat bed malfunctioned and caused one of the cables to burn damaging the connoctor between the main bored and power supply

So I have fitted a new mother board and heat mat but the printer just will not print a single thing, I have checked the levelling, the extruder, the software and nothing will get it printing.


Please, does anybody have any idea what the problem could be here??

Thank you in advance!

did you upload the firmware to the motherboard?

Ahhh...this could be it. How is that done exactly?

What board you have? There is different firmwares for each board . but basic way is to download the Arduino IDE and the firmware from It's source, connect the board to the IDE and flash the firmware.

RepRap Pro has a verry detailed guide how to do evrything ,you have thier mandel 3 Right?
