  1. Re: UCNCV4 usb cnc controller board with opto isolation and relays and offline functi

    Probe or Tool Sensor?

    There is a wealth of information at https://planet-cnc.com/blog/?category=obsolete. I use the Lower (-) Z limit. The Tool Sensor I have, has the probe switch and an...

    Hi Berin,

    I added a consew clone to my taig, and ended up re-rewriting the FW on the STM8 to do PWM to V curve adjusted to the isolated V-V converter I bought. I also added an RPM sensor, but...

    Berin - You Rock! I now have PWM and VSO working. On to wiring in a Servo motor!

    Thank you so very much.

    If I can hep you trouble shoot the 4 Axis HW let me know.

    Awesome!

    What is not working is the PWM and VSO on connector N).

    I have the SWITCH G) to the TOP and the SW configured to use OUT3. I can see the signal on the ST8 pin 24 (PC7...

    berin,

    I have this controller but the stm8s903k3t6c was left not programmed. Do you have a ST-link that you can read the programs and EEPROM data out and post the hex file?
