We have a 2017 Shapeoko 3XXL CNC Machine. We recently ordered a BitSetter and a BitZero 2.0. The instructions we found on line mentioned updating the GRBL file on the bios of the Shapeoko circuit board, ours is a v2.4d. We did that. Our new version is GRBL V1.1f. Now that we have done that we can’t get the Homing process to work. Machine (Router) or Z Axis’s wants to go down hard on our board and not up. We’ve tested the limiting switches and they seem to be fine.
Could we have made a mistake updating our GBRL file on the Shapeoko Circuit board? We saw a note that we didn’t catch earlier about not updating the GRBL file if you have Homing Switches. We didn’t think that applied to our machine, but now we aren’t sure. Are our limiting switches actually Homing switches? Do we need to go back to the version of the GRBL file we had earlier? How can we find the old GRBL file for our machine and the instructions? The machine did work fine until we flashed BIOS on Circuit board.
Did you send the machine configuration? Usually when your z axis goes the wrong way it is the config. Hook up usb cable and power on Shapeoko and connect but do not initalize. Go to settings and choose config. Go to second tab and turn off bitsetter. You can leave bitrunner on if you have one. Go back to first tab and send configuration with z type. After congig is sent then initalize. After you are sucessful with initalization you can turn on bitsetter and config position.
Guy is most likely correct.
Rewriting your firmware means the board doesn’t know anything anymore, so you are now in the “I have a brand new machine” position in the Shapeoko lifecycle and need to reconfigure everything.
