				Hi all 
 This is my first post.
 I use do make my PCBs with mach 3 rev2.031 and every thing was working fine.
 today I switch to 060 but feeddrate was reducing gradually from 254mm/min to 50 mm/min (or 10"/min to 1.9"/min) after 5000 program lines.
 then I reinstall mach 3 rev2.031 and every thing returns to normal again.
 is there any explanation.
 here I attach 2 nc pcb files one in inch and another in mm (same problem with both)
 thanks

				Hi:
 
 Havent seen that before. Does the commanded feedrate DRO also lower?

				Hi Art , Brian
 thanks for your reply
 commanded feedrate DRO (function 2018) is not changing
 it is either 254mm/min (metric)  or 10"/min (Imp.) all time.
 it is (function 2013) that lower gradually with program lines until machine stop.
 Regards
 Joe
