    Excellent - what did you change it to?
    Changed to 20mm supported rails on the long axis - 1100mm, shorter axis (700) 16mm , Z (300) 16mm. Chai seems to be a good guy and altered the order on my request. The primary use for the machine is to cut hardwoods for guitar bodies and the secondary use is for carbon/glass fibre and light (6060) alloy. Aiming for a cut area of the machine of approx 900 x 600. My initial calcs for the maximum static deflection on the long axis, assuming a 30kg carriage of 0.12mm. The supported rail should stiffen this - but I could be wrong.

    Thanks for the link - I'll examine this in more detail tonight
