How to home the slave sensor?

Greetings from Denmark.
Hi every one.
I have recently finished my cnc router and could use some help.
Have not been able to home my gantry automatically.
I am running with MACH 3 and NVUM V2 usb interface.
All 3 axes have their own home sensor and in addition the slave also has. Has two steppers on Y axis. (A as a slave). Everything moves perfectly and home everyone works too. First Z, then Y and finally X. The problem is that the system does not look at A home sensor. I have manually moved A axis about 10 mm further away from home, but when I try to home Y then the gantry does not straighten so it is at a perfect 90 * angle.
In the diagnostics screen I can see all 4 home sensors separately.
What am I doing wrong?

Kind regards Laszlo

You are doing nothing wrong, you just have wrong controller.
AFAIK NVUM/NVEM controllers don't support squaring with slaved axis.
Get rid of that controller and buy a decent one like ESS.

I have never used this controller but most other controllers you would need to set the home switch input for A and Y-axis even though you are slaving them, have you done this.?

Or better still one that uses UCCNC software like the AXBB-E or UC300 so you're not stuck with ancient mach3 or buggy mach4, plus you'll get decent technical support which you won't with an ESS.!

Thank you so much!! i will check ESS out!

Hi
Yes i did but the system only react to the Y and not the A sensor.

Would be a mistake, the UCCNC and AXBB-E or UC300 from here knock the spots off the ESS and Mach3/4. Much easier to set up and far better software, also cheaper.

Thank You!
I have to use Mach 3 because my "teacher" has the same program.
I'm a beginner!
Which of the two controllers is best for Mach 3?

Both the controllers I linked to can use both Mach3/4 or UCCNC software. The ESS can only use mach3 or 4.

UCCNC works just like mach3 but is much more stable and doesn't crash or do crazy things as mach3 does. Mach4 is full of bugs and I wouldn't touch it with a barge pole.
I have used mach3 for nearly 20yrs and I can tell you with 100% guarantee that UCCNC is far far superior. The controllers are also better than the ESS and the support is second to none unlike that of Warp9 who makes the ESS.
