@cardoc: i didn’t get to test the sv08 macros.cfg - i found the problem instead. the green cable of the can-bus cable from the mainboard to the aux buffer feeder was crimped so badly it slipped just out while checing the wiring again. the plugs are micofit 3.0 mm 4 pin - wich i do not have around, and i found no way to get the pins out of the plug to solder the wire back on 
i ordered some plugs and cable at ali, and wait for the replacement cable from sovol to arrive.
Can you email @sovol3d about this with pics please.
hello. yes of course - and i did over a week ago, your ref. no. is PBID007941122
