or you can do what i did and hire marc to do a custom plc. I used an encoder on the rear of turret to do positions. Had to make some adapters and whatnot to make it bolt on, but works perfectly and i have the same hi-low hydraulic style. In case yours dont have the correct inputs or wired to their compatibility of the way logic they are using.mindego wrote: ↑Wed May 24, 2023 5:32 am Hi guys,
I'm new on centroid so I hope that my problem is simple and easy to fix.
I'm retrofitting Fanuc 6T lathe with hydraulic turret.
Using OAK PLC with customized „Centroid_Standard-Lathe-OAK-8-tool_electric_atc-R1.src“.
Tool changer do Indexing correct. But when I run example T0200 M6 it make all positioning job correct, but I get message on screen „waiting for input #32 (M94)“ and job hangs up.
What should I do that all process will end correctly.
Waiting for input #32 (M94)

Maybe I should use clean installation without any hidden ATC functionality?

I retrofit this m.c and did following
1) make turret uni direction
2) short all 12 switch to active slow solenoid
3)in that way only 13 input used but turret used only in one direction

Dear aamir,
My program and turret working perfectly with original equipment without any hardware changes. With two speeds.
There are somewhere in hidden PLC source added some secret functions which required this "input #32" for tool changing (M6).
And it is funny that this input I use for 8 tool sensor, but I still get this message and then the 8 tool is oriented (sensor triggered).

You have installed a PLC program for some type of turret (nominally an 8-position Centroid-supplied Taiwanese turret which uses an electric motor for rotation, and which automatically unlocks as the motor drives forward, and automatically locks as the motor drives in reverse). However, you have no tool-change macro file (cnctch.mac) installed at all.
With Parameter 6 = 1 to select automatic tool changing, but no tool-change macro file, CNC12 falls back on a "default" automatic tool-change sequence: probably something equivalent to this code from the Mill control:
That would only work if the PLC program responded to M94/16 and M95/16 (through PLC system variable SV_M94_M95_16), and if a tool-change-complete signal were wired to INP32 (which would be the last input on a PLCADD1616 board, if you are using an Oak control).
In practice, no one ever uses the built-in "default" sequence, because it does not fit any real-world situation. A turret lathe retrofit always requires a cnctch.mac file that is matched to the code in the PLC program.
If you are going to use a PLC program that you have derived from "Centroid_Standard-Lathe-OAK-8-tool_electric_atc_r1.src", then a good starting point would be to locate the cnctch.mac file that went with that PLC program, and copy it into your c:\cnct directory.
Then, if your turret does not exactly match the one that your PLC program was written for, you will need to review the turret unlock/rotate/lock and position-feedback sections of the PLC program, and modify them as needed for your turret hardware.

M107 ; send tool number to tool changer

It should be very simple problem. I create M16 function with same code like in my M6 and now machine works like a charm
I realy don't know where I should looking for this kind of information of your system.
In future, where I should looking for system required files?
