Delay at end of each drill op
« on: October 30, 2007, 09:13:42 PM »
I'm not sure where the delay is coming from in the following code (just a newb). This drilling sequence gets to the hole and does the drilling just fine but once its back to the clearance position it just sits for about 1 second before moving to the next position.

preamble

G17 G20 G40 G54 G64 G90
<other mops>
Z0.0829 F47.244094
(Standard Drill )
T3 M6
(0.04)
X1.8925 Y2.5750 Z0.0200 F47.244094
G81 X1.8925 Y2.5750 Z-0.0745 R0.05 F30.0
G80
G01 Z0.0500 F30.0
G81 X1.9925 Y2.5750 Z-0.0745 R0.05 F30.0
G80
G01 Z0.0500 F30.0
G81 X2.0925 Y2.5750 Z-0.0745 R0.05 F30.0
G80
G01 Z0.0500 F30.0
G81 X2.1925 Y2.5750 Z-0.0745 R0.05 F30.0
G80

<etc>

I know the G01 is simply the move to the new position, G81 is the canned drill cycle and G80 cancels the drill cycle, but thats about as far as my knowledge takes me. What is causing the delay and how can I get rid of it?

Lol! Actually, I just noticed the feedrate.. Dunno how/why it went to so many decimal places. Have to check the visual mill settings.

Hi, PatM

Under Config, Ports&Pins, Click on Spindle Setup, lower center, General Pramiters there some delay Box's for CW and CWW delays.

Hope this Helps, Chip

Ah, I see it. Since I don't have spindle speed control I didn't pay attention!

I'll try it out tonight. Thanks much!

It took longer than I thought to get to doing another board. Tried it this morning and setting the CW and CCW delay to 0 had no apparent effect. There is still about a 1 second delay between finishing one drill op and moving on to the next.  Could it simply be that it takes that much time to decifer the next drill op? I'm running a 3.2 gig P4 (single core) with two gigs of ram and just about everything shut off (over a gig of physical ram free before I start Mach).

Please Please  put a fix for this on your to-do list!

G81 has a pause before moving to the next hole.   I estimate the pause is around 700ms (the dude above estimate 1second).   With today's noodle-hertz CPU speeds.... what on earth could be going on during this time?   I realize .7s per hole ain't gonna put me outta business, but it makes my mill look bush-league -  the ladies' aren't impressed by the doddering movement, especially after they've seen those super-fast mills on youtube.  Please please please fix!   U da man.    Spock out.
