No thats a valid point and taken on board.I have made this machine myself and was cutting out some letters when it keeps going in to trip or reset mode.And it has only happened since putting on the limit switches so it is down to that i think.I only wanted to finish the letters before i delve in deaper can you suggest any particular wire i can use for this project.
many thanks for you comments

I dont have any other device connected to it no printer no scanners nothing.Because i have re routed all my wires can having the power cable too close to the stepper motor wires cause any trouble of any kind
thanks for your reply

Hello all i do hope someone can help me on this problem i have only just started having

I have recently made my self a form of workbench to house my cnc router on the top of it and placed my PC and my stepper motor drivers and power supply below on a shelf
So I can slide a clear Perspex door across to stop dirt from entering now since I have made this and placed all my equipment in it my PC starts up fine and when I start my mach 3 everything is great but as soon as I turn on the steppers my PC slows right down as if a program is taking up all the bandwidth
My mouse moves very very slowly across the screen.Is there any idea that you can think of which will cause such a problem.
I have looked in the windows task manager and the only program I have running is mach 3 which is only a few percentage of my total bandwidth

ps i am running xp mach3 cut 2d and nothing elase
