I am in the process of revamping my machine controls.
I have set up the dust collection system to be controlled by relay 7 on the relay board.
can I program a aux key to turn this on? if so how? or do I need to use one of the coolant buttons?
sorry if this is a dumb question when it comes to macros etc I am still learning..

thank you,
Charlie

for a router the easiest way to run dust collection is to simply use the "Flood" output.
use the wizard to assign "Flood" to the output you want the dust collection to be controlled by.
then you are done.
M8 turns it on
M9 turns it off
and the Flood Button on the VCP has both auto and manual mode and can turn it on and off as well. easy peasy


for more info on how to use the Aux keys and their corresponding macros...here is a video..

Charlie...
You can do either. See Centroid Tech bulletin #300

https://www.centroidcnc.com/centroid_di ... browse.php#

To me the "mist" button looks more like dust and the "flood" button looks more like vac hold. If you want some easy files to make it happen pm me and I'll share. The M9 turns off both by default, but that's easy to change. Using these will save you an aux button and only a handful are actually usable at this point. I'm waiting for the router update.

Wasn't there a rumour that the VCP buttons would soon be editable? That would finish the job off very nicely!

yes..that is in the release after the one we are working on now..thanks.

I keep hearing this "rumor" also, I'm anxiously awaiting the release myself, this will put the finishing touches on my machine.

thank you all for your input ....
you all have very helpful I will look
at all the info provided and see what will work best
for my setup .
Gary I looked at the tech bulletin 300.
in there it says:
The Acorn has default macros for turning on and off general purpose outputs as listed below.
• M61-M68 turn on OUTPUT1-OUTPUT8 respectively M94/61-M94/68
• M81-M88 turn off OUTPUT1-OUTPUT8 respectively M95/61- M95/68
I am sorry for all the questions... so my understanding of this is that M94 turns on the desired output. and M95 turns of the desired output.
if that is correct can you press the button once to turn on ...then press a second time to turn off ? if so how would that be written to work?
trying to understand this better .

thank you,
Charlie

I have my dust collector set up as if it was flood coolant. The post-processor for Fusion 360 I'm using automagically inserts a M8 (Flood Coolant On) after a tool change, and a M9 (Flood Coolant Off) before the next tool change and at the end of the program. It couldn't be easier.

clint,
thank you for the info
I am not using gcode to turn on and off at this time but
will more than likely do that in the future...

thank you,
Charlie
