f 0.2 changes by itself?
« on: May 27, 2019, 11:06:04 AM »
Hello Chaps
Using a wizard and turning a 50 mm dia plastic rod with mach3 .
I use feedrate set to mm per rev
the roughing cut is set to f0.2 mm per rev, but it doesnt always start
at that feed rate? usually it starts at a feed rate of 0.02mm which is much
to slow.
but not only that
the finishing feed rate is set at f0.2mm as well . when the program get to
that block it often ( but not always) jumps to over 1mm per rev??
any suggestions ?
all advice is gratefully recieved.
someone said a work around will be to use feed per minute?
many thanks
