Does anyone who knows GRBL well know of a board/controller that will support homing all 5 steppers on the lowrider? So it will have 5 stepper drivers and end stops?

Your best bet it the grbl esp board for the mpcnc. If you have any doubts, ask Bart on his build log slack.

This is still more work than the rambo from Ryan. And it’s $40 plus you need 5x drvs and an esp32.

Do you have to have a slack account to contact Bart on there? I have questions but slack seems to be a paid service

I definitely don’t pay, and I don’t think you have to. I am just not sure how you get invited… Let me ask that over there and I’ll get back to you.

Thank you Jeff!

I’m wondering if maybe I got the link after ordering something… Not sure if the intention is a public space or not. But I know Bart is pro open source and community, so I am guessing it is ok.
