Guitar tuners are used to tension the system and to adjust the tilt of the gantry.
The gantry can't get accidentally tilted.
I do have plans to kit this printer. I am shooting for the end of the month.
I plan to only make a few a month.
It's understandable I suppose. You've got some lucky students, man. You should really look into getting some kind of manufacturing partner to turn out a steady line of kits though. Ideas get taken a lot more seriously when they've got sales numbers attached.Quote
I am trying to balance my day job with this without taking away my time to design and build crazy things.
I have hacked together a Marlin branch for my machine. I don't claim that it is a general solution but I would be glad to share it. I would spend more time on making the firmware handle generic transformations but ARM chips seem to be the future and Smootieware is good at that already.
Would it be so bad to move the Z rails and bearings to the other side of the gantry?
Then the pulleys could move out further toward +-X.
The string forces wouldn't be in the same plane as the guide rails, but not far away.
