ToM Extruder Relay Fix

thingiverse

The provided text is not my finest work due to limited resources in a hotel setting. However, I have identified an issue with ToMs' extruder motor failing, which seems to be related to glitches on the extruder controller board possibly caused by power supply issues. As a temporary fix until MBI provides a proper solution, I added a relay board to the EC board output, enabling successful printing of several objects without complications. The required parts for this workaround can be purchased at Radio Shack and should be assembled according to the attached schematic, while being cautious about diode and capacitor polarities. Please refer to the provided cautionary notes as well.
