I have entered the modern era with a 3D printer. In particular, it’s an “Original Prusa i3 MK3,” kit version. Assembling the kit was not complicated or confusing, but it was a serious test of my limited dexterity and took about 20 hours of focused work.
Nevertheless, the printer is assembled and working, and in case it ever helps anyone, problems with X-axis length errors and XYZ calibration can possibly be resolved by loosening the screws holding the back-plate on the extruder assembly. That plate puts pressure on the X-axis bearings and can cause your extruder to not slide as far as it should on the X axis. If your Auto Home check is correct in Y but not X, maybe look into this.
Below are some pictures of my first couple results and some videos showing the printer in action.
Wow, this is amazing!! What all can you make with this printer. Can’t wait to see it.
Finally, you bought a 3D printer, that exciting Kyle!
