Auto Router Turn On Code - Question re Pause

Machines (Original/PRO) Controller (Buildbotics) Discussion

I posted this within another thread Tool Enable - M15 - & Breakout board (auto turn off/on router) - #90 by Orthobill13, but wanted to make this a stand alone.

I added the iot relay and Break out Board. Works great thanks to the above instructions.

Question: When the router starts up, the tool path is pretty much ready to go and starts immediately. I would like to have a short pause, maybe 1 or 2 seconds, to make sure the router is fully up to speed before it starts. What is the g code for that?

I tried this in a test run:

G90
G20
(Contour.T…)
M05
M0 ;T102
M03S10000
G4 P2
G0X2.8086Y3.4370Z0.1500
G1Z-0.0500F8.0
Y5.5630F20.0
X5.1914
Y3.4370
X2.8086
Z0.1500
M05
M02

The pause, or G4 dwell works, but not in the sequence I would have thought. The dwell of 2 seconds happens before the router turns on. As soon as the pause finishes, the router is activated and the tool paths happen. I would have thought having the pause after the M3 line would pause after the start of the router?

Do I need to add a G00 line for the x to move up a little, then pause, then let the program run?

Anyone do a pause? Is this an issue?

Thanks all! Bill

This is my output from F360 pp. The controller pauses cutting for 10 seconds after the spindle has been initiated
“N25 S8000 M3 → spindle on
N30 G4 P10” → 10 second pause

Actual gcode is below.

Thanks for the reply. I tried to code in the G4 line again, with a 2 second pause. It is still pausing without turning on the router and vac, starting to move and then turning on.

Here is a video of the start sequence, you can see the line of code, hear the machine start to move, and then the router and vac turn on, which is still out of sequence I feel.

Here is the start of code that I was running:

G90

X3.2706Y4.3698
etc…

Anyone have any ideas as to why the router is not starting first, pause, and then run the code?

Spooky - sometimes it helps to test extreme cases to expose an error - experiment with a +10-second delay. It may be that your spindle needs more than 2 seconds to get going.

Great idea Andy. I tried that this morning. The pause was for 10 seconds, and then the router started right up AFTER the pause, not before like one would think it should.

Not sure what is going on…

Update - the issue just is not at the beginning of the run. I ran a really run just now, and between every move, in other words between each G0 move, the router is turning off and then back on before the cut. So during any given job, it will turn on and off several times. Very unsettling, I plugged the router back into a non switched outlet for now until I can figure it out.

Here is a video of that occurrence:

Any help would be very much appreciated!

SOLVED: I remember seeing a YouTube video of another person using the code to turn the router on and off. You need to deselect rapid-auto-off and dynamic-power under tool setting. Duh.

Not sure which one was causing my issue, but solved now!!! It turns out without delay, perfect.
