ToM Extruder Relay Fix
-
- Created on Jan 8, 2011
First this not my best work by far. I am staying in a hotel and have limited resources to be able to build this properly.
Some of the new owners of ToMs have been experiencing problems with the extruder motor failing after a short time. I was able to see that the problem is related to glitches on the extruder controller board possibly due to the power supply.
As a work around until MBI develops a proper fix, I have added this relay board to the output of the EC board. As a result I have been able to print several objects with out issue.
