Yep I'm still here. Just been debating and waiting on parts.
so i've been dicking about with my moch up as i learn better in the physical.

So then i had my Y Axis working. I used a toothed belt after someone asking why not.
Now i know why not. Me! I'm soooo lazy. A chain can be a length or a loop real easy. Belt not so much.

Then I worked on my X axis movement.
Had to get creative as no coupling have turned up so far! Annoyed YES!

But i had hit the weight limit for the cheapy motors i had. :(
No drama

All is not lost.
