I’ve been trying to find what each connector on the controller does and the pin mapping as in FAN2 = PA3 stuff. Has anyone at Sovol released this information?
It’s in the SV08 repo in github:
SV08/Motherboard/MCU_PIN_definition.pdf at main · Sovol3d/SV08 (github.com)
I found three PDF files but none of them show the actual mapping as in:
J1.1=+5
J1.2=PA1
J1.3=GND
If you look at the way BTT maps their controller boards along side of each connector it shows which pin is what, easy to follow., hard to screw up.
I just want to know the mapping for the XYZ stop pins and what voltage they are using on any connector (+5 or +24), I can always break out my Fluke voltmeter but it would be nice if they provided a detailed pin map.
I just added a USB A to USB C cable to the USBX2 where the camera is plugged into(after I removed the heat glue gunk), I need another MCU added to control a chamber heater and a CPAP exhaust fan, another new cable routed to replace the filament sensor cable with 4 wires instead of three allowing me to use the BTT SFS V2.0 since Klipper now supports filament pulse detection. .

Does not show which pin is which value of all ports
e.g. Filament Detraction PE9; Danger to assume, Blue smoke, could maybe try a multi meter but tat is a big job just to find which pin is +5v which one is the signal and which is ground
The other problem with using an Voltmeter is pull-up resistors, with a pull-up resistor a pin shows what ever voltage that is applied to the pull-up…
