ATC Automatic Tool Changer Setup

Hi Dylan

All looks good there are many different ways to do the pneumatics and all of them can work
My one tip is to make sure your tool holders have some flex in them they need a bit of give
and just be careful with your dust / Air blast pressure as if it a little to high you get a trapped air cushion that pushes the Iso25 tool holder 9or what ever you are using ) down up to 5mm bending the printed rack tool holders or if they are not flexible they will snap I thought I had a problem with the safe Z distance setting then I though it was low clamping air pressure but in the end it was air blast / dust pressure that was to high
anyway keep in touch I would be keen to follow your progress

one last thought I would add at least one more filter / Water traps to the system, compressors that run a lot, pull quite a bit of water out of the air and you need to be able to control that efficiently

Cheers Bill

The impact of the high air blast pressure is good information to know, and a great bit of troubleshooting on your part. I have recommended the spindle we are using on other forums and I frequent, and will be sure to remember this should anyone there encounter the same issue.

The warning of accumulated moisture is also noteworthy. I am always surprised at how much I drain out of my tank at the end of the day and my 3D carves. One thing I did was modify one of my filters by removing the micron cartridge, and replacing that volume with blue silica gel desiccant beads. I have my pneumatics in an enclosure, and every few days just have a look inside to see the colour of the beads. It just adds a third line of defense against moisture, but also helps determine the state of things in my line.

Hi Blackjack and tmtoronto,
I have everything working except for the pnp sensors (11. & 22.), im not sure what i'm doing wrong, as i have connected them as following.
Sensor 11.
Brown wire to +24v
Black Wire to masso signal (input 17 with 5k7 resistor to positve on masso)
blue wire 0v to ground

but on the masso screen where the inputs are they both always are on high.
any suggestions?

Hi Dylan So is that one spindle sensor to input 17 and the other to input 18 ? and I see you have not assigned tool change inputs 1 to 17 and tool change input 2 to 18 yet . I did not use a resistor I did not have any reference to do so . input 1 should be low when clamped and high when unclamped, you can invert them with the space bar I hope that helps cheers Bill

The sensor inputs switch there state when the signal from the sensor is on or off if you are suppling power all the time via the resistor it will it's state will always stay the same

Cheers Bill
