VC 12, mach3, smoothstepper ESS, Gecko 540, BOB a nice smooth running machine.
I'm 84 and have used my DIY 36x48" linerar bearing, ball screw CNC for over 15 years, primarly cutting 2D and V carve plaques very simple, no homing, soft limits, needed until I do, set Zero in the center and go.
Recently I was doing a resurface of the bed and gave it a cut size slightly larger than the bed and it hit the Y++ stops, and the right Stepper connector coil broke then it reversed direction to the - direction and because of my machine size I have two Y axis stepper drivers, and the YSlave side kept driving forware until I hit the ES, skewing the Gantry, I fixed all of that but I need to have some built in protection for this forgetful old man to protect the machine.
I watched several methods of control, and settled on two Priximity Sensors for wach axis and YSlave and only the top of the Z travle. I developed a little circuit board for all the axis with an out voltage of 4.78 VDC. Conned it ti the input pins however, thats as far as I have got It doesnt react exactly on all axis like I think it should.
Mach has so many screens and sub screens I cant figure it out.
A year or so ago I had my CNC PC die, and even with a backup I couldnt get it going again after hours of guessing and struggling.
I posted my problem and was contacted to have a tech connect to my PC and within 30 seconds of looking around he found the problem and I was back in business.
I have trid to solve this problem by contacting the BOB manufacture several times, describing the issue, and him not understanding, and saying its not worh his time for a $29 BOB.
I really need one person to see for themselves what the settings are and how it is reacting, not four or five novices leading my down the winding paths full of side trails.
SO, LOL after all that Is there someone that can connect to my CNC and get me on the right path. to having a safe and accurate CNC.
If you got this far thank you so much
