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!

Welcome to the forums, sorry to hear about your issue.

1) I take it the power supply is still good?
2) Is this a direct replacement board from the manufacturer?
3) Any and all software updates install/configured?
4) Does your computer "see" the printer or were you leveling manually?

I think a few facts would help. When you say you can't print, what do you mean ?

Can you home axes ? Can you extrude ? Or can't you even do that ?
