many thanks thats handy to know i don't mind paying a little extra when its worth it. I am still having trouble deciding how to do this x axis and wether i did the right thing going for rack and pinion as i think it is proving a little tricky to fit it all in with the gear box and tensioning system. something keeps telling me i should maybe look back into belt drive as it gives more flexibility on were you can put stuff. If it was bet drive i could easily mount the motor above the x axis like in the picture or have it stationary on one end of the main frame.
