hello budgie
i know that this thread is from 2011ad, but i recently started using Hi-Cut Pro, and i was searching for such threads
please, about this code :
Code:
G131 J2 E0.01 F10000
G01 Z4.9 F10000
X-74.278 Z4.837 F2250
X-74.281 Y62.084 Z4.775
are those coordinates for a 3D toolpath ?
it seems that HiCut_feed_upper_limit is the same with the feed for "rapid" approach ( 10k ), and after that the toolpath is cut at 2250; the cnc may struggle a bit to target 0.01 precision at 10000mm/min ... i would try this :
Code:
G01 Z4.9 F10000
G131 J2 E0.01 F2250*1.2 (*)
X-74.278 Z4.837 F2250
X-74.281 Y62.084 Z4.775
(*)
( upper_feed_limit a bit bigger than programmed value, but not too big, so to avoid machining at "exact" feed value )
( i don't know if using HiCut_feed_upper_limit = 10000 has same effect like = 2250*1.20, but i know that using )
(HiCut_feed_upper_limit = programed_feed_value will lead to force feed corrections, because during machining the feed )
(may go over 2250 )
( feed oscilations around programmed feed value is a normal thing, and the feed corection should not be )
(forced also by the HiCut function )
or this :
Code:
G131 J2 E1 F10000 (*1)
G00 Z4.9 (*2)
G01 X-74.278 Z4.837 F2250
X-74.281 Y62.084 Z4.775
(*1)
( machining tolerance will always be below 1, because encoders cinematic is pretty sharp; this will )
(allow the machine to move more "freely&smooth", especially when the toolpaths segments are tangent, or )
(close to being tangent )
( E0.01 will output a greater accuracy near toolpath joints and machining time will be bigger )
( still, E1 will perform faster and may deliver a nice result )
(*2)
( Hi-Cut is disabled during rapids )
