Hi all,
After a long time away from all things CNC i've finally got back into it and have become so pre-occupied that my wife reckons i'm having an affair CNC.
Any way I was drilling a grid of holes in the bed today to take hold down bolts and hit a few issues:
1. I was getting few random limit switch faults. I have used shielded cable for all steppers and for the VFD, but not for the limit switches. Could this be the cause???
2. I was doing simple plunge movements into the MDF bed in a 100mm x 100mm grid with an 8mm router bit fitted to the spindle (its all i've got at the moment). There is enough flex in the gantry that you can see it move and it results in an elongated hole instead of a round one.
Does anyone have any tips on how to stiffen the gantry. it is 150mm by 50mm by 2mm RHS tube
