Well I feel a right plonker!
Saturday morning I started my quest to find out what was going on with my machine, first thing moved my home switch wiring to another BOB only to find the the LED's were still flashing on the diagnostics screen.
So another check of the voltages and everything checked out ok until I checked the opto relays I was using to switch the 24v to 5v, 5 volts going in 2.3volt coming out ! So straight to the BOB removed the wires from one of my home switches and linked it out, solid LED on the screen.Removed the opto's replaced with some 24v relays problem solved.
Now the missing step saga,all the time I have been checking the problem I have been using the same G code program, I had checked the code and everything looked good, when I was running the tests with my plunge gauge there was no sign of any missing steps(differnet code), I went back to my cam program I had used for creating the code and found that I was trying to move the tool 17mm a sec! I know the machine would only achieve it's max that is set on the motor tuning page, but never the less I thought this might be the problem,I adjusted my toolpath paramaters and created the G code loaded it into the machine, NO MORE MISSED STEPS
It just go's to show how a series of events can send you down the complete wrong track, I had convinced myself it was the new computer. I will look on this as part of the very steep learning curve we all embark on when we set out down the home cnc route.
Thanks Hood for your help and anyone else who chipped in with advice.
