A transient voltage problem
created by the welder arc start cycle has been slowing the machine build progress. I know there is a solution but not being strong in electrical engineering has left me poking in the dark for answers. One of my Linkedin connections, Michael Fitzpatrick suggested contacting his friend David McQuate at Clear Stream Technologies for assistance.
David rode across town yesterday on his Easy Racer recumbent bike to examine the machine.
After studying the driver board schematic and the machine he made several suggestions.
He suggested adding this circuit to the limit switches to stop the voltage intrusion.
Hopefully this will turn a corner in the design and the pace will pick up.
