Well, I’m finished with all my axes… sort of. I kinda mighta sorta installed my X axis on backwards. (!!) The belt that drives the extruder is on the front, while the gears are on the back. I’ve thoroughly inspected it and consulted my trusted advisor (thanks John) and I really don’t think it will be a bigger problem than telling the software that things are reversed.
Worst case scenario, something about it just doesn’t work and I will have to partially disassemble the printer and switch the axis around. It wouldn’t be the end of the world.
