cnc router x axis starting before y axis finished when pocketing ?

Thanks for the extraordinarily detailed response Jazz, it's very helpful and has given me much to study and experiment with.

By the way, the pockets in the pictures are 150mm by 30mm, 3mm deep and cut with a 6mm compression bit from the Cutter Shop in Fareham. The Gcode was generated in Vectric Cut 2DPro and run by Mach3 to my 1220 x 850 (with 2.2Kw spindle) router which was made by RNR Designs in Stockport.

If you Zip up the file and attach it I will take a look. Vectric posts are notorious for spitting out segmented arc's. I believe there may be a post-processor that is available which uses G2/3 arc moves so it might be worth taking a look at which post you used.

Thou to be honest any properly setup router should easily handle cutting what looks like a 10mm radius at 3mtr/min. Who set up the motor tuning, you or RNR.?
I don't know this company or the router but if it's built stiff enough and properly setup then it should easily handle cutting at those feeds.
