Thank you both, I have read some of the manual, but was watching some utube clips by the Guru Brew and he explains it really well and I think I am getting to understand things more, re pin numbers and setting up that to mach3, anyway I have fitted the switches and hoping to wire them up this afternoon once I have finished refitting the pcb and the 4pin plug and socket I will start to set it up again, I have forgotten Everything I manager to do in 2016 before my operation stopped me doing anymore hopefully I can refer to the U tube clips to go forward, if I get stuck then I hope I can ask on here again
