Ran into a strange problem with my shapeoko 3 (which I bought in January 2015) where I created a simple square 1" x 1" x 0.1" in Carbide Create and using Carbide Motion it cut a 2" x 2" x 0.2" on wood. I’m using Carbide Create build 313 with Motion v3 build 368. The dip switches are for 1/4 step (using NEMA 23 motors) and $100-$102 set to 40.
Using MDI in Carbide Motion, when I type y25.4 it moves 2 inches instead of 1 in.
Looks like there were some other advancements while I was inactive- like homing switches which will allow me to upgrade to grbl 1.1 and the shapeoko upgrade z-axis plate. If there’s any other changes, let me know as I’m putting my cart together now.
Thanks! Will email - one symptom I’ve noticed is that if I turn off my Dewalt router, the CNC reboots itself. Fortunately, it doesn’t happen when I power it on or while running. I presume this is due to EMI?
Also can try routing the power cord as far away from any other wiring as possible. Mine goes out the right hand side of my machine, opposite the stepper wiring. I haven’t tried this, but others here have tried and been successful in adding a 3 wire power cord to the Dewalt. Extra wire (ground) goes to the Dewalt case.
