So my mate who wired up my panel popped round :)
Multi meter came out and a quick decision was the PNP proximity limits I had were wrong ,they did actually need to be NPN-tried 2 he bought with him and all good :) pass as to whats the difference! so theyre on order:)
Moved onto the spindle which I was having real problems with as well ,trying to get the speed control working was a challenge!
The ST-V2 bob is a strange beast it turns out! what with the limits being right but actually wrong the spindle wouldn't keep it's speed ,it just kept dropping off???
So after trying just about every combination of pins and reverse settings we got to minimum and max speed% in the UCCNC software.
It was 10% min 100 MAX.
Set it to 100% minimum and 10% max and all good!!!!!! can't figure it out but speed control is working well and powers on and off fine.
Any ideas as to why are very welcome :)
2 steps nearer to a first proper run woohoo!!!
