Does this work? I keep getting no feed rates specified as an error. Trying to use this with the Gradus M1 Pro. I'm not using the Estlcam CNC controller with this setup. (Maybe it works? Maybe it doesn't? I've no idea. If I try it will it brick the board if it doesn't?) Using 2D mode. I switched to Chilipepper from grbl panel and it just touched all the holes followed by drilling one hole where the outer outline of the object should have started. My unemployment is preventing me from spending a bundle on this and I like estlcam's price. I could buy it and something like this ... https://amazon.com/gp/product/B07CG8GKTB ... which would keep costs down. But I'd rather just use this with the Gradus M1 Pro that I have. Any tips for using estlcam with either the Gradus M1 Pro or with an OX CNC?
