John's Alu Profile build

[Evengravy]

The Z axis came with three optical sensors inside, I kept one in there as upper homing limit switch and reused the other two as home/limits for the Y axis, one each side. For mounting I machined a carrier from Delrin/Acetal. I'll probably replace this with aluminium at some point soon.



The plates which mount between the Y axis bearing blocks and the gantry were modified to fit a piece of aluminium L profile, this moves into the optical switch when homing.



For mounting the Gantry to the ballscrews on the Y, I had a local company weld me up some brackets to my design.



They made a bit of a balls of it to be honest, It's not square and I had to rework it by hand a lot. I can't weld so I didn't have much option, I really should learn to. Since I'm replacing these chinese ball-screws with ground screws from TBI I'm not going to sweat it just yet. Once the parts are here I can redesign this part and the motor coupling for each.

I'm using LinuxCNC 2.8 for this with kins, if anyone wants me to upload my .ini and .hal files let me know. It's working well so far.
