The right extruder on my Artist-D stopped working. So I first looked at typical issues such as a plugged-up nozzle. Once I was sure it was not any of those, I decided to determine if the stepper motor was turning. Unfortunately, I needed to start taking things apart to see the stepper motor spindle with an enclosed hot end. (Once I had it apart, I realized that I could look through the side grill to catch the stepper motor spindle.)
It ends the carriage that holds the hot end assembly is attached to the hot end unit with four screws and is accessible to disassemble. Just unscrew the two adjustment knobs, one you press to release the extruder gear to load filament and the second that holds in the nozzle. Take out the four screws, and the unit drops out.

Well, I plugged the ribbon cable back in, went to the front panel, and verified the stepper motor was not turning. So now it could be the cable, the adapter board, the cable from the adapter board to the stepper motor, or the motor. I thought I would be smart and try it on the left side, which was working. BAD IDEA. As soon as I powered on the unit, I saw the cable begin to smoke. Fortunately, I caught it in time, and when I reattached the left side, it still worked. So now I know the pin assignments on the left side and the right side is different. Interesting.
Ok, I am a lucky guy, and YouTube (Google) sends me a bit, a tiny bit, of money for the ads that run on my channel. So I dug into the MakeWithTech bank account and ordered a new right extruder and all new cables from JG Maker. Ordering was easy. Know I we will see how long they take to get from the warehouse to the Midwest of the USA.
I report back what I learn.
You may be asking why didn’t I replace the extruders with a third-party extruder. I want to keep my Artist-D close to stock to do videos that make sense for the broadest number of people.
