If you have read my last post on the Cupcake CNC, you would have heard of my firmware woes.

Basically, what has happened was that I fried the boards (both the motherboard and extruder controller) during hotplate reflow soldering. It seems that the AUD$10 hotplate was simply too crap and the temperature spiked high enough to damage something (I never got round to desoldering the microcontrollers and testing each one).

In the end, I shelled out more cash to get replacements, figuring that if I ever repaired the boards, I could put it towards building a Mendel.

After receiving the new parts and testing that everything was fine, I proceeded to build the plastruder (plastic filament extruder), and will continue the rest.

Lets see how things turn out from here.
