Centroid Community CNC Support Forum

There was a fellow in NC who had the exact same machine. He's trying to sell it. I'm familiar with it.
Someone set the steps per rev incorrectly at 16000
The overall turns ratio is also not correct. Someone set it up like Mach 3

Please post pictures of your control cabinet. Overall picture and the Acorn board.

I'll look at your old report in the morning.

Here's the photo I added earlier.

Closeup.

So if I understand correctly maybe this one works because both numbers are wrong but match up together, but maybe in the new version they just won't work? The person I bought it from is a high end watchmaker and had that machine for at least 3 years.

Oh that's interesting about the overall turns ratio. The number shown in the Wizard in the 4.13 beta version is not the number saved inside the report txt file. The file has the number I was seeing in 4.64 after I had imported the report.

I did a bit of digging to understand the turret and it looks like I would have to copy the files from the custom turret folder into the cnct folder, then set a few machine parameters related to the ATC in the CNC12 config to what they were. I can try that later, after I'm free from work. I guess the first thing is to figure out the correct axis parameters.

These are the motors installed.

Here is the thread, sorry it was a PC Turn 120

You are looking to extract that file and work with the centroid_acorn_v460_lathe_universal
You have 4 bit gray logic. I believe 1 output

From your Acorn PLC, Output Definitions:
NoFaultOut IS OUT1 ;&*;
RotateToolTurret IS OUT2 ;&*;
Flood IS OUT3 ;&*;
SpinFWD IS OUT4 ;&*;
SpinREV IS OUT5 ;&*;
DriveResetOut IS OUT6 ;&*;
OUTPUT7 IS OUT7 ;&*;
OUTPUT8 IS OUT8 ;&*;

Inputs:
;------------------------------------------------------------------------------
; INPUT DEFINITIONS
; Closed = 1 (green) Open = 0 (red)

ToolTurretPosBit1 IS INP1 ;&*;
ToolTurretPosBit2 IS INP2 ;&*;
ToolTurretPosBit3 IS INP3 ;&*;
ToolTurretPosBit4 IS INP4 ;&*;
DriveOk IS INP5 ;&*;
;unused IS INP6 ;&*;
;unused IS INP7 ;&*;
EStopOk IS INP8 ;&*;

Your PLC was created by a Centroid employee. They used a Beta Copy of software at the time to start working on ATC's
It was created on December 14, 2018

You have what you need along with the PC 120 thread to get going.
In your Reportxxxxx.zip file there is a Reportxxxx.txt file. It has the parameter settings. You could print it out or just print the section with the parameter values.

This is why we suggested you back up the original CNCT directory to multiple places. Has all the machine parameter settings.
If you read the ATC Instructions for 4 bit gray logic one output, it will tell you the parameters that you need the values from.

Thanks Marty. I'll go back to all of this as soon as I get some time later today. Any pointers regarding the steps/rev and turns ratio settings? I saw a video from you where you set it to 8000. Do I need to connect my PC to the Dyn4 and see its settings first? And what's the best way to figure out the turns ratio? I think that when I installed the 4.64 version, the wizard had set 2000 steps/rev as a default for Dyn4.
