I’ve finally gotten around to upgrading my Shapeoko 2, and everything seems to be working. But the “logic” mode never provides power to the spindle.
In a brief attempt to troubleshoot, I bypassed the controller altogether and jumped the logic contacts with a bit of wire, and even that doesn’t work. So I figured there’s a dead relay or whatnot.
Taking the power supply back apart, I see the relevant MOSFET assembly has a contact that isn’t soldered but that’s just the heat shield and I assume irrelevant?
I’m just a software guy, can someone who’s a little more EE help me diagnose this? Asking Inventables to just send another part is a last resort, since they take a long time to get here to Europe.
