I guess I assumeed that connect to Norbert goccapy pins would do this and the gui buttons at the same time, guess I need to do them both.

You need to forget about the gmocappy pins. I don't use them and it works.

You do need to be on the jogging tab or it won't work. Thats what I use my yellow button for. TO always select that tab.

Dunno about the Guru bit. But did you need to be on the jogging tab? Was that the key?

Like you said, forget netting with the GUI buttons. Although I then did that as well in parallel, just to see if you can have the screen buttons follow the INCR switch. But that is probably pointless.

I used it to tune my servos, but I thought here that the encoder had no output, so it seemed easier to hook up the toy osci.

when your chasing threads on a lathe the first passes can be a little deeper but as more of the cutting tool makes more contact as you get deeper the depth of cuts should be smaller. something else too remember is with steel it takes more force to cut than softer material so going a bit slower on the RPM would have probably helped with these small lathes.

it looked like the shaft was sticking out quite a bit and with small shafts if it pushes to much the work wants to climb up over the tool like it did before the job got sideways on you. one thing you can do to avoid this is to center drill the end of the shaft and use a live or dead center to support the end of the shaft. this will keep the work from climbing over the tool and bad things from happening the next time around.

machine looks good though.
