Switchwinder X1

I followed some other guides to convert my Sidewinder into a Switchwire a while ago. But the motor mounts and the upper idlers aren't in the correct place. The belts run to close to the gantry. This design should fix that.

Conversion of the Y-Axis to linear rails is inspired by: https://www.printables.com/model/175809-artillery-sidewinder-x1-y-axis-linear-rail You can also keep the v slot wheels.

I have converted my Switchwinder to most of this design. The only thing remaining are the linear rails for the y-axis.

You can reuse the stepper motors, but I bought new ones from Stepper Online (17HS19-2004S1).

You will not reach the speeds or accelerations of the Switchwire. Everything here is bigger and heavier, espacially the bed (even more so for me and the aluminium bed that I have installed).
