Hey guys, I’ve had my shapeoko 3 for about a year but have recently started having random disconnect issues. I thought maybe it was my laptop so a buddy came down and we connected his tablet to it, still disconnecting.
Now, after connecting his tablet. Nothing is working right. Homing is going front right and grinding(because there is no limit switch on the front). Can someone please help? I’m thinking it’s something in grbl settings from the research I’ve done but it won’t initialize or anything.
How do I get to the grbl settings to check?
I’m running carbide motion version 640. And it’s the belt driven z.
I’ve tested the limit switches and they all work according to the led lights on the control board
Does that then allow initializing? If not, power down and slowly, gently move the machine to the center of motion for each axis, power up and connect to the machine and go to Settings | Debug — are any switches stuck on? If so, investigate.
Static electricity is the main reason for disconnects. With the weather turning cold the humidity is going down across a good part of the country. The second culprit of disconnects are the brushes on your router. On Makita/C3d you only get about half the new length before they need to be replaced. The wire is relatively short and when the wire gets extended the brushes start arching and making electrical noise.
So double check your grounding and replacing the brushes is very easy.
Alright, I figured out a few things. While trying to figure out what was going on….the y1 and y2 plugs to the controller were swapped(I bought the unit second hand) so I’m guessing when the person I bought it from put it together they ran the y1 to the wrong motor and just corrected by swapping at the controller instead of having to pull wires back through the loom. That corrected the homing front instead of back.
As far as the disconnects…. While trying to figure out the homing issue, if I turn the machine off but leave the usb connected to my laptop, I was able to move the machine manually along the axis’. When sliding it along the x axis at a certain point you can hear it disconnect and reconnect. So I’m thinking a break in a wire somewhere? I didn’t think about the brushes but I’ll check that too. I have the carbide 3d router.
