hey, nice work. Printed all parts, assembled with an E3D, fits perfect !
But, you don't say anything about any change to any firmware... I know, several versions are used out there, no doubt. I use marlin on my kossel/rostock and search for the point where to add or uncomment lins to activate it.
What firmware are you using, are using you other guys out there ?
What changes are needed for getting it working ?
Can you post some examples ?
