Ok so Im trying to fix a Shapeoko 2 for my college as a final project in my CNC class. Somehow the school got it a few years ago the class at the time put it together but never got it working. Since I have experience with 3D printers it turned into my class project.
After allot of troubleshooting it seems GRBL was overwritten or corrupted on the Arduino so I reinstalled 0.9 from their Github using xloader. Im running the Universal Gcode Sender and I’m using the setting as found here. https://wiki.shapeoko.com/index.php/Grbl_Configuration I tried Candle Gcode viewer and got it to connect but it does nothing aside from that. Anyway, for now, I’m just using the UGS for testing.
So I can connect to the Arduino and I can jog the axis stepper motors but they just vibrate is if they are drastically underpowered. Z is disconnected from the screw so it can turn freely and it just buzzes. The other axis is connected but they moved free’ly manually so its not a binding issue. On the UGS I can see the steps counting up or down as I jog the axis but again they just vibrate and dont move at all.
I checked the troubleshooting guide and it might be my computer, Its just a tablet so it may have an underpowered USB. I also have the screwed up mouse control but the PCB’s are all insulated on the router. The entire machine is basically new and has never run a single part but I suppose there could be something wrong with the drivers or power supply. Any sugestion on what next to try would be great. Thanks.
