Sorry but just before I posted Doddy had said that his knowledge of Mach3 was rusty as he used other systems, I then wrote my post out giving all the information as to what had happened, or so I thought, then after that he came back with more suggestions which I carried out.
It's alright for you to have another go at me, I probably asked for it, (I don't think,)
You are a very helpful chap but a bit touchy and prone to being abrupt.
What you need to understand is that you know what you are talking about, I am trying my best to just learn how to use a machine I have had for at least 3 years that cost me in excess of £1100, but due to illness and health problems I am only just trying to get to grips with.
I have looked at other BOB's and know they cost £8 upwards, but room to fit another BOB that may be larger is tight and would mean me moving things in the control box, more technical problems for me, then I would need to know how to connect everything as the connections are different to my existing one.
Therefore if its all the same to you I will try to get the Bob repaired.
I will stay on this forum but hey honestly you don't have to reply to my posts or help me, if there is no one else that can then that's fine, I will succeed I assure you.
As an aside it didn't show limit exceeded,but was showing an emergency stop activated, due to the Bob being faulty and not switching XYZ 5volt to 0 Bolton pins 10 11 and 12, so again you made me look like a complete Pratt again.
Thanks for all your input though
