Hello All,
I just finished building the RigidBot but after two successful prints the nozzle stopped heating up. I'm not sure how to diagnose the problem. All of the axis controls still work, and the extruder fan is running but the heating element is cool. I have a multi-meter, but I'm a noob with electronics so I don't really know what to check for or how to use it. I'm thinking I should check to see if there is current going to the heating element first, any ideas on how to do this properly?
Thanks
