Galil / Re: While Drilling a Hole in Z axis Mach3 says it is done before reaching bottom

it's a servo system - if I touch off the tool to the top of the stock it is at zero
position on all axis has been maintained - the torque limit is set at max
it's as if the z axis is allowed to lag behind and then catches up

Galil / While Drilling a Hole in Z axis Mach3 says it is done before reaching bottom

« on: December 20, 2009, 07:48:57 PM »

I have a old excello 3 axis knee mill - it had a dynapath 10 control orig. - that died 10 years ago - I coverted it over to camsoft with a galil 1730 board
that died 4 weeks ago - it ran on win 98 on a old motherboard with 2 isa slots - one slot was for the galil the other for a board to a opto22 relay board
now have win xp on a old mother board with one isa slot for the galil - now for my problem - i can move and jog all axis - home and limits work
we use featurcam for g-codes and programs - even ran a plastic job just fine - current job is to drill a 3/8 hole in s.s. 1 1/8 deep - as the drill is pecking
down at 5 inches per min. the machine dro and program dro show all the right numbers - but as the drill force builds the feed drops - program finishes
which means the hole is 1 1/8 deep - but it is only 1/2 deep - if i rerun part it will drill a little more out of the hole - during all of this if i watch the dro's
they show correct at all times - even showing the drill tip at 1/2 deep when it thinks it is done - if i dry run the program with no stock it will drill the full
1 1/8 deep - what setting do i need to fix to maintain this lack of movement
