Thanks guys.
But now i've got multiple problems. They are as follows.
1. Motors sound like they are randomly skipping beats as the axis moves up and down.
I assume this means that the motors are missing steps and that probably led to no 2.
2. I tried to cut my first part today - (A dust guard attachment to attach my hoover to), and the result is wildly off what was it was supposed to be. I mean like between 3-5mm errors across the piece.
Circles not circular etc. A complete waste of time...
Just to say - I have lost count of how many times i have set calibration across all axis with "set steps" and an accurate ruler, and it seems reasonably accurate in Jog Mode.
When you run gCode the head seems to wonder. It certainly never returns to 0,0,0 in the work co-ords.
3. Machine Co-ordinates won't zero as mentioned previously.
Could it be the HyCNC 125 USB board that is causing the inaccuracies and skipping, or is it more likely to be the stepper drivers?
Is it a set-up thing. I have spent all week on it and have got nowhere. Trying all kinds of settings.
I have these tb6600 drivers, and i have tried several mirco step options - 1/16 and 1/8th...
I have also adjusted the ampage pot up and down which made no difference.

Thanks for any help you can give me to get started....
Best Regards
