Building a 3D Printer, RepRap Mendel Prusa2 by craynerd
raynerd:
Hi, thanks for the posts guys.
The prusa has been a little ignored over the last few days but I have had a good few hours with it last night.
Despite my best efforts at machining a coupling, I found the thread was unscrewing while the motor was moving. I could have tapped the coupling for a grub screw on the threaded end but I decided to give the plastic couplings a try and they seem much better. I think consequently my z wasn`t moving.
I`ve also been using M92 g code to set the e-steps on the fly and observing the differences - this has been better.
Got some pretty good prints of bearing holders last night.
I`ll post more pics and progress soon. Once again, thanks for the interest.

Cracked it...finally!
If anyone makes one, learn to tune the E step on the fly with M92 E .... with G-code!!!!!!! Two night work sorted in 5 minutes.
Also, I`d got a wierd copy of Marlin. I`ve moved over to Sprinter now.
Z axis was out by a mile... now it is square my prints look v good!
Here is a case for my new Raspberry Pi!!

Nice one, Chris; raspberry on the front and sort of raspberry coloured, too :clap:
I'm often stuck for a box to house some electronic project; being able to make your own custom ones must be a real boon.

Grand job Chris, might get you to make one for me if your board :)
PS

Hi Chris,
Super job! :thumbup:
Is the rest of your post in some sort of Cypher?
