Been there, done that, got tears all over the T-shirt. There's quite a saga in the archive here of problems I've had with the spindle causing spurious tripping of limit switches when using a cheap Chinese BoB and LinuxCNC via a parallel port. I'm still not entirely sure where in the chain from BoB input to PC motherboard the problem really was. The shiny new AXBB-E controller and UCCNC software installation running via Ethernet have been faultless so far.
