Title: Feedrate really slow when running a line with G43
Post by: mhdale on September 05, 2006, 06:51:52 PM

What feed does the system use for a G43 Operation? When its performing this move its super slow and changing the feedrate on the screen does not affect it...

There should not be a move when you do a G43... G43 is a tool length offset...

Brian, Here is the Code in my file right after the tool change.

T1 M06
G20
S10000 M03
G53G0 Z0
G00 G90 X1.0914 Y1.4791
G43 H1 Z2.
The last line is the line it is on when its moving down to the starting position for the job.
I tried using the feedrate thing we discussed on the phone, but the feedrate showing on the DRO is 60 but it is only moving as fast as the speed I used for the last Tool Hieght probe move.... Any Suggestions?

Try putting a G00 on the same line as the G43. It should be going at G00.. that is odd

Brian I have tried everything I can think off and I cant seem to find what is causing it to feed so slowly at the beginning of the program.. It allways uses a feedrate of 8 and no watter what I do I cant seem to change it. It is doing it on all of the files now, and I know it wasn't before.....Obviously I have changed some setting.....but I cant find it...and it's weird, It rapids to Safe Z Above the start and then uses this glacial pace to drop down to the First Start point at which time everything picks up and runs normal.... I have a 12" Z so it's getting kinda annoying.. any suggestion on where this feedrate might be set?
