High-Speed Printing Using ODrive

[HebigT]

Not my printer, but wanted to share Vez3D's ODrive set-up on a corexy printer.

ODrive is a BLDC controller which can drive 'lower'-cost bldc motors via several input methods, including Step/Direction.

Vez3D is using it as part of the benchy speed boat challenge.

Here's a long video going over the configuration for a printer:

And an example print (~30sec):

The motor current must be very high, but it's quite impressive.
