Hi
I have just set up a Chinese 6040 cnc( i know its cheap but i just want to try it out,so far i'm hooked  ), it all seems to work great but when i loaded my g-code (from aspire ) the job was 23" x 9" but it cut it out approx half size?
I've been through the set up a couple of times and used the setting that came with the cnc ( which were brief to say the least!  )
Can any one give me some idea of what might be wrong and how to fix it.

Cheers Tony 

I'm just guessing but, check your steps per unit distances, put tape measure on the table and command a move along it, see if its close to accurate or what.

Hi John
Thanks for the advice, had a ply around with the steps per unit and got it sorted 

Cheers Tony
