I have a new Creality Ender 3.
I suspect that I have not adjusted the eccentric nuts correctly, on the X-axis head carriage mounts.
Even after a glass bed upgrade, using the Level Corners routine of the TH3D firmware, I can get the head to scrape…

How many times can you re-flash the Marlin firmware to a RAMPS 1.4 board before it degrades the ROM?
First of all I'm working with a Folger Tech Prusa i3 kit, if that makes a difference. Also I believe the Arduino is a Mega 2560.

What's a good way to secure bushings in a 3D printed part?
I'd like to secure bushings in 3D printed parts. They would be used for a drilling jig. I've seen heat-set inserts, but they've all had threaded interiors. The best idea I can come up with is printing the plastic hole several thousandths of an inch…
