leadscrews and threaded rod Prusa I3
Posted: Sun Jan 28, 2018 5:41 am
Hello all, I'm hopeful someone here will be able to help.
In my first venture into 3d printing I've bought and assembled one of the Prusa I3 kits. I was having a lot of problems with the Z axis refusing to move.
On removing the threaded rods I found they were bent leading to the Z axis seizing up.
I've bought and fitted couple of leadscrews which has sorted out the movement problem, however the threads per inch on the leadscrew is very different - one revolution of the M8 threaded rod gives a lot less vertical movement than an 8mm leadscrew.
I'm guessing I need to change something in the software somewhere to re-calibrate the movement?
Can anyone please point me in the right direction?
