Hi..

I use KFLOP + KANALOG + KONNECT to replace the controller on my old CNC's lathe. This lathe has turret with 10 Tool's Slot.
I want to run Automatic Toll Changer with command M6 Tx (x = number of tool). The turret works by hydraulic, to turn it only require one output (bit 150) that will enables the hydraulic's solenoid valve. A solenoid valve will move the plate to unclamp-> turning to no. tool destination-> clamp. The hydraulic mechanism allows only one-way rotation.

On the back of the turret, there is rotary encoder (2500 pulse/rotation), supposed for detect the position when the turret was turning, I connect the A signal to Input bit 1054 and B signal to Input bit 1055.

There is one switch on the back of the turret for detect when the plate on 'clamp' position, I connect the switch to Input bit 1051

The working order of the Automatic Tool changer is as follows:
- M6 Tx commands from Gcode program or MDI
- Axis X and Axis Z move back toward a safe position
- Output bit 150 ON
- Wait time for t second -> t corresponds to the moving distance from the current tool to the destination tool. The time required for clamp and unclamp 0.5s and time required for  turn each slot is 0.2 second. For example, to change from tool #1 to tool #3, the total time required will be 0.9s.
- Output bit 150 OFF
- Axis X and Axis Z move forward to continue the next program.

I also want KFLOP to remember the last position of tool's number that's used when the machine is turned on after it is turned off.

Please help me the example of C program to do the above work.
Sorry, I'm just an electrician, and just learned about the C program.

Really very grateful for your help.

Hi Tom,

Thank you for suggestion,

I check the encoder, yes it has differentials output. But temporary I don't connect it to KANALOG. 

I try to do some test of the C program from the following link, http://www.dynomotion.com/ wiki/index.php?title=Tool_ Changer_-_router_linear_4_ Tools_-_C_Program

Everytime I type : for example Tn M6, with 2 or 3 or 4 etc,  the same bellow message always appear : 

​ 
​

I checked on the KMotion console, it show some information as follow :

Before, I create a file in C:\Temp\ToolChangerData.txt, for save the last tool, and on the file I wrote 1,  is it correct ?

It's looked like the program can not read the number of desire tool Tn.

I dont know where is a mistake, probably it's jumped ?  .

Much appreciate for your advice..

Regards

Hi asmec,

I think you will need to connect the encoder to a hardware Encoder input.  Does it have differentials outputs?  See:
http://dynomotion..com/faq. html#Encoders

Have you studied this to see how much you can understand?
http://www.dynomotion.com/ wiki/index.php?title=Tool_ Changer_-_router_linear_4_ Tools_-_C_Program

Can you identify the Functions?

Hi Tom,

Many Thanks for your support..

Now the machine able to do  "automatic tool change" very well.

Hi asmec,

Note: the line shown below in the C Program defines which persist variable the program expects KMotionCNC to place the Tool Slot number to load.  The M6 command in KMotionCNC Tool Setup should be configured with the same Var Parameter to match.

define TOOL_VAR 9          // Tool changer desired new tool Var

HTH
