Yay! Finishing up in the hardware department. Got the belts on, motors mounted, and wiring with parallel splices installed for X & Y axes. Took off the disastrously bad universal mount I printed the first time (Hatchbox: Not Even Once), and installed the one I reprinted with GizmoDorks PLA (passable, and Amazon delivered it next day). Here’s a helpful tip: superglue the nuts into the tool holder nut traps, so you don’t spend a half hour trying to screw in the tool mount and instead knocking the nuts out over and over.
Now I’m trying to get the laptop talking to Marlin on the RAMPS board, to see if I can make something move!
