Finally configured the laser printer I found on the side of the road. I’m guessing either the PCB or the motors are damaged since the machine basically has a mind of its own. Sometimes, the Y-axis controls need to be inverted, and other times, the x-axis controls need to be inverted. I think I found the sweet spot this time though. (Maybe this was on my part too since I barely know the $ commands)
My pen plotter can now:

• Move in the direction told WITHOUT triggering an alarm
• Successfully Home itself (It would go to the other end and make the most gruesome sound)
• Move the actual distance shown (Would move 0.8mm and think it moved 1mm). - Doesn’t send power to z axis! (Doesn’t have one).
• Recognize soft limits and restrict its movement if the code goes beyond the machines size.

I’m barely getting started with this too. Now, I need to send it some G-code and see how it writes. Also, I need to make a custom pen holder to mount the pencil/pen. Gonna have to use Thinkercad. Also gotta figure out how I’m gonna get it to translate words into G-code, but it’s 1 step at a time.
