Improvements to core_xy #209

Closed martinbudden closed 2 years ago

martinbudden commented 2 years ago
  1. Better default parameters
  2. Changed plain_idler_offset to work in x and y, to facilitate larger idler pulleys

This example uses 25 tooth idler pulleys - they have larger and wider bearings than 20 and 16 tooth pulleys and are hence more durable. CoreXY

Is there a bit of the green belt missing?

martinbudden commented 2 years ago

If you zoom in you can (just about) see that the green belt is hidden behind the blue belt.

Here's the same setup from a slightly different viewpoint CoreXY2

Looks like the test needs updating to put the screws in the right place.

OK fixed now. Turns out this revealed a minor bug in the corexy y_carriage plain pulley position, which I've also fixed.
