We're building a new machine and we've run into an issue where we need to have the motors connected in such a way that our X- and Y-axes are flipped. We need the torque from the Y1 and Y2 drivers on the two NEMA23 X-axis motors, and we need our two NEMA17 Y-axis motors to connect to the single X driver. Right now, we have to very carefully check our placement before we start a cut, so it's a little nerve wracking. I assume that it's just a change in the GrblHAL firmware and a re-flash and that should be it, but I figured the best place to ask is here. Thanks in advance!
You can use Y2 for X as well if you want to: set X to Ganged: See http://svn.io-engineering.com:8080/?driver=ESP32&board=BlackBox X32 This will use X for X1, and Y2 as X2. Y and Z does their own as usual.
