Mach 3, Win 10, smoothstepper, Gecko 540, BOB cs25, proximity sensors. Size 48" x, 36" Y, 7" Z. Two steppers driving the Y axis.
I built this CNC aproximately 17 years ago and use it all the time but now I will soon be 85 and with memory not as good as it used to be, so I need to build some safety procedures into the CNC. I really would like to have a mentor that could give me accurate suggestions, rether than several users giving me their opions.
I am using Proxcimity Sensors (PS) on X-, X+, Y-, Y+, Y slave, Z+ and moving metal near each one causes the Leds on each related input pin to light and go into a reset state, hitting reset twice removes that state.
I have watched several YT's and I am unsure about positioning the gantry as to how close to the positive stop and the indication point.
Let me describe how I think it should be set. Move the gantry aproximately 1/16" from the positive stop, then very slowly move the PS closer until the cnc senses it and secure the PS at that point. Is this the proper procedure, if not please tell me the proper method?
Concern: I sometimes very slowly drive the Gantry into the left and right Y axis positive stops to make sure the gantry is in a square state, I set the positive stops with this in mind. Will I still be able to do this with the PS setting I described above.
Thank you
