Bad pictures yes. 2nd x axis rail not in use atm.
But it will have one. Y axis both rails in place.
Well its different, it will be interesting to see it cut :applause:
Well she moves real smooth. But it's nowhere near put together. It's literally clamped down.Quote:

From the look of your sprockets and chain you'll not be doing anymore cycling...😁

The tricky thing with chain drives is that the smaller sprockets give you terrible cogging and the larger sprockets give you enormous travel per rev requiring expensive low backlash gear boxes to get any king of resolution.
Totally get that! Been doing countless searches on Sprockets and sizes to see what method would be best to resolve travel distance to rotation. Thinking i'd use some sort of gearing to compensate.Quote:

If you are serious at this you could design in Fusion360 it is free for hobby use, a big learning curve but it has CAM built in so you could use for generating the gcode later on.
There are plenty of tutorials on it. like https://www.youtube.com/playlist?lis...Alt9yzBIp84sD8
