Re: Swing arm ATC
Owen,
i'd plan on buying some tech support time.
install the swing arm plc program when installing cnc12
and follow this typical swing arm schematic as a guide.

Re: Swing arm ATC
Hey Keith thanks alot
Re: Swing arm ATC
It is a good idea to enter the software travel limits, even if you do have a full set of limit switches.
Soft limits will prevent you from jogging full-speed into a limit switch. They also allow the control to tell you when you first start a program cycle whether that program, at some point, commands a move that is outside the machine's travels.

Re: Swing arm ATC
HI Keith, Sorry to hijack an old thread, but I can't find a swing arm plc program for Oak, where would I find one? Anyone have one that works?
My swing arm changer has the rotary barrel type encoder in the front with 4 proximity switches above it. I am almost finished installing an Oak to replace an Anilam 5000M, and I am blown away by the lack of information available. It appears to me that if you want to retrofit a hobby bechtop mill or a bridgeport then it's ok, but if you want to do a real machine for industrial work, there's just nothing available.
If the green light ain't burning, you ain't earning.

Re: Swing arm ATC
Hi, i've asked chris our in house plc programmer to post the generic Oak swing arm plc program here. you can modify it yourself to match your retrofit project or have the plc program customized to your requirements by us or others such as cncsnw.CrossfireX wrote: ↑Tue Apr 27, 2021 9:27 pmHI Keith, Sorry to hijack an old thread, but I can't find a swing arm plc program for Oak, where would I find one?

Re: Swing arm ATC
You can also start with this one, if you prefer:
http://www.cncsnw.com/OakUnifiedPLCHowTo.htm
... and operational guidance at:
http://www.cncsnw.com/UnifiedATCSwingAr ... orInst.htm
You will almost certainly have to make changes to suit your machine, or hire me to make them.
I have never seen a swing-arm gearbox with four prox sensors. They most commonly have three. You will have to find out what the four sensors actually indicate.

Re: Swing arm ATC
Keith, thanks, I would appreciate any help you can give. I've found PLC program on the console for Redoak with swing arm ATC and it looks like it's just about right for what I want, maybe I can modify it, but maybe I'm wrong too, I'm that confused now that I don't know whats what...
cncsnw, Thank you, If I can't get this solved myself in the next day or so, I might have to hire you, I wish I had known about you before I started, I woudl have just hired you right at the start so I could have all this done before I even got the controller delivered. In relation to the 4 proxy switches: only 3 were connected as far as I can tell, I mean they were all connected, but only 3 were used. I took videos of a tool change in progress showing the drum rotating and the proxy's switching on and off, but I can't find them for the life of me. just a silly question though, in all of the connection details I can find they reference "Arm Clamp", "Arm Home", and "Arm Stop" but which is which? I assume that Arm Home is the left, Arm Clamp is the middle, and Arm Stop is the right? I dunno.

Re: Swing arm ATC
chris will post tomorrow the oak swing arm plc program that we have used on some in house machines.
but Marc (cncsnw) is probably your best bet for quick service on a custom PLC program!

Re: Swing arm ATC
There is an illustrative comment at the start of the swing-arm ATC code in many Centroid PLC programs, and in mine:CrossfireX wrote:I took videos of a tool change in progress showing the drum rotating and the proxy's switching on and off, but I can't find them for the life of me. just a silly question though, in all of the connection details I can find they reference "Arm Clamp", "Arm Home", and "Arm Stop" but which is which?

"Home" senses when the arm is in its idle/parked position.
"Stop" senses when the arm is at any stopping point: home, first tool-clamping position, second tool-clamping position, or back at home
"Clamp" senses when the arm is at the tool clamp/unclamp position (gripping the spindle tool and the magazine tool)
If you have the common setup, of normally-open sensors detecting notches, the light on each sensor will turn off when it is indicating the condition it is supposed to indicate.
