Hi rustyolddog

I am vary happy! Your tipp to install those capacitors worked out well. Now my cnc milling machine does as it should!
Many thanks for your support and have a nice Sunday.
Regards
Martin

If you say 0,01, do you mean uF, pF or nF for the capacitors?

Hi Rustyolddog as a matter of fact I'm using shielded cables separately for switches and motors. But still facing this certain problem. As mentioned before I will try with capacitors and see what happens (or not!?). But now as not an electronic specialist where exactely do you put the capacitors in? Ground is clear but than where would I have to hook up the other leg of capacitor. Maybe you can explaine oer send me a sketch by email! Thanks anyway

Hi rustyolldog I'm very happy having found someone who was facing the same problem. That's the reason for why I placed this message in this forum. Next week I will get me some capacitors and try all over again. The result I will report to the forum and as well to Dave Rigotti who supllies those driver boards.
Thanks a lot for your help so far and have a nice day.
Kind regards
Martin

Thanks Hood for your input. Yesterday evening I tried this but it didn't change anything. But as you may have seen rustyolddog runs the same driverboard and he might have the solution with the capacitors.
Anyway thank you for helping!

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
