Auto toolchanger tool length setting
« on: January 05, 2015, 12:58:10 PM »
Hello everybody,

In my diy toolchanger, there is z height probe sensor and five tool posts. In operation, every time there is tool changing, new tool is brought to the z height sensor and was sensed its tool length/offset. Take an example, in my machine, the vertical distance between the workpiece's surface to the sensor of the auto toolchanger is 40mm.
(sensor is at level above the workpiece surface)

1) I don't want to use the tool table for storing the tool lengths.
2) In the program as below, I also don't want to manually enter the value 40mm to the input box.
 -----
 ZNew=GetVar(2002)       'Read the touch point
 Code"G0 Z" & ZNew        'Move back to hit poin tin case there was overshoot
 Call Wait
 z_set=Input Box("Please input the set z height")
 Call SetDRO(2, z_set)      'set z DRO to input value
 -----    
So, is there any place in the Mach3 screen that I can enter this 40mm value and the program can call this value? I either don't want to load or design a new screen to cater for this fuction.

Thanks guys in advance..

Look on the offsets page there are several DRO that are raely or NOT used on that page .

Hello,
On the offset page, there is gauge plate thickness, I want to put the value 40mm to it and use it in the program by calling it. But it seems that there is no standard DRO number for it. Is this true? Or, what the other buttons\DROs I can use?
Thanks

Open it with Screen4 and see that it is 1001 ... and the one lower is 1002.

On that page there are 2 plate thickness DROs they are User Dros  the one on the top left is UserDro(1001) and the one on  the right side is UserDRO(1002)  IF I remember correctly.
