C programing Q

[LarsSweden]

Hi Tom and everyone else.

I´m have some issues with my M6 program or g-code.

After a toolchange my Z axis "loses" it´s position.

When running a cycle on the ATC, in program mode, and using G43 comp the Z axis when trying to return to Z0. it ends up way above the position it should be. Sometimes above the Z limit...

In my ATC program file i send the Z axis up to zero pos by using Move(2,0) and Checkdone(2).

Can Move cmd change the G54 or Machine Pos?

Is there a way to check if an axis is at 0 Machine cordinate, in the ATC C program? So I can skip the Move cmd in ATC C prog and just check if it is at Zero(Home Z). Then using just G28 Z0 before any toolchange.


GCode example:

***before toolchange****
N9888 M5
N9890 G91 G28 Z0.
N9896 T52 M6
N9898 G0 G90 G54 X49. Y-36.6 S1500 M3
N9900 G43 H52 Z0.
*** After toolchange it end up above Zero(G54 Zero)****

I don´t have the ATC C file on this computer, but i can send it if need be.

Hope my explanation is understandable...

If I start a nc program and the correct tool is already is spindle, checks this first in ATC C program, It will go the correct Z hight (in G54) when theese lines run:

N100 G21
N102 G0 G17 G40 G49 G80 G90
N104 T53 M6 (Already in spindle)
N106 G0 G90 G54 X62.872 Y-43.231 S1500 M3
N108 G43 H53 Z0.

but if it would have to change tool rightaway it would end up above...

Hi Lars,

Is your M6 Program in KMotionCNC configured for "Exec/wait/Sync"? If any C Program moves any axis it should specify this in order to properly re-synchronize the GCode Interpreter with the new position.

Hi

Yes, that was the problem, had it Exec/Wait.

Working!


Is there a way to get 4 axis fullscreen?

Thanks!

Hi Lars,

Thanks for posting back.

We are working on ways to make screen edits easier. But no promises when.

I have to get one more Konnect board, total of 3 boards. Is it ok if the third board has a ribbon cable almost 20 cm long? Between the second and third board.

Hi Lars,

That should be ok.
