Mr Graham, thanks for your help. I checked the recommended settings and everything seemed fine. I then reinstalled the mach3 programme and redid all the settings. Now I'm getting the 4th to move with the x-axis key. Is it possible to have the 4th operating independently?
Another issue I would like some assistance with is accuracy. the steps were done using the auto function in mach3, I did it for 10mm /1cm however, when I send a file to cut I'm off by 25mm less than my desired size. The manufacturer settings are way off I'm using aspire to generate my G-code. is there anything I am overlooking here.
