General Mach Discussion / Home Limit Switch problems Mach3 with HobbyCNC Pro
« on: October 20, 2007, 08:46:29 AM »
Hi everyone
This year I bought myself the HobbyCNCPro kit and a 3D milling machine.
As operating SW I decided to by Mach3 from Canada. A very useful
Software, off course!
Now everything went perfect until I wanted to set up the home/limit
switches. I'm using them as follows: Xhome/X-- and X++ in series as
well as Yhome/Y-- and y++ in series. At Z axis I'm using Zhome and Z++.
This means I have on X and Y 2 switches in series and in Z 1 switch.
Now according to the Mach3 manual I've set up and activated all inputs.
If I'm looking at the diagnostic page I see the LED lighting up but
nothing happens. Even more I get the message that a limit switch is
triggered. So I disabled all switches and operate the machine with soft
limits. That works but I would like to use those switches.
I use NC switches and all have the same ground at HobbyCNC Pro and I
use the pins 10 (X) 11(Y) 12(Z). At Mach3 active low is not activated.
I own an older version of the 4AUPC Choper Driver kit. If I connect the
same kind of switches there (with or without power on) Mach3 recognises
the switch an stops immediately. May there be a problem with the length
of the cablings. My Maschine has travel in X 950mm and in Y 650mm. The
longest cable may be (Z) over 2m. I'm using shielded cables with .14mm2.
Does anyone have an idea where I would have to look at.
I appreciate all your efforts.
Kindly
Martin Steiner
