Sorry I should of said I had all axis moving via pc keyboard and was very slow
Before i changed the numbers jazz gave me I realised the 800microstep I said it was set to was way out as the drivers only go to 512 according to manual so I thought I'd go into protuner and double check but I plugged into the x axis drive when powered up and since then the motor didn't have power to it but the green led is on the drive
Next day I then plugged the cable into the z axis driver and couldn't communicate with pro tuner so checked the connections and noticed this had happened

What do you mean by a P between driver case and pc?

Im sorry to be confusing
