UCCNC allows to set softlimits to give more safety to the system. Unfortunately the configuration needs always a lot of configuration steps until it runs. I’ve written some easy macros and modified the defaultscreen of UCCNC to make it very easy and comfortable.
You need UCCNC in version 1.2x (here I use 1.2020 from free-download
www.CNCdrive.com
;of course you need a license from Stepcraft or CNCdrive if you want to operate UCCNC!!!).
Also you need a XHC-HB04 from ebay:

(it's my German post but there's a link to ebay...)
How to do:
Rename your original “Defaultscreenset.ssf” file to “Defaultscreenset-original.ssf”.
- Place the attached macros to the macro folder of UCCNC.
- Place the attached screen to the “screens” folder of UCCNC.
- Click on “Configurations” and then on “General settings”. Click on “configure plugins” and
- click on the configure of “XHC-HB04 pendant”. Make the changes as you see in the attached screenshot with exception of the Macro7 (it’s not necessary for the softlimits).
- Now APPLY settings and SAVE settings.
- Now restart UCCNC and you should see a modified RUN screen (upper right corner).
Withyour remote now go to the most left back position and press MACRO-1 button. You will get a short response from the x/y motors.
Now go to the most allowed right front position and press MACRO-2. Same response…
Now press MACRO-3. On the RUN screen the LED (Softlimit active) should now be GREEN.
Check with your handwheel if the softlimit is working.
Info about my setting: on the y-axis the “DIRECTION POSITIVE” is enabled (“checked”).
I did not add a macro or modified the macros for the Z-axis. You are free to do!
Hope it runs and I didn't foget any info you need. So come back with questions, I will help.
