A axis shift

[Jimmy Wakeford from Barefoot CNC]

I am working on a haas 5ax head/head machine today. We have discovered that the A axis is .178 degrees off from being vertical. Where can I put this .178 value in to shift/ compensate when homing the machine.

 

We are using the tool setter and renishaw so I don't want to just put it in G54.

How about G52

[Post dept]

Yikes, so this is a VR? Are they running with G143 tool length compensation??

[Jimmy Wakeford from Barefoot CNC]

Yes, its an older vr. We are not using the G143 tool comp on this control, would be nice. We use the macros for tool length and G54's. Then plug tool length intop the overall length parameter. Slick as a whistle.

 

I want to do a grid shift on the axis. I am worried that some of the probe setup cycles are working off of machine home and a G54 or G52 shift will not be correct cause the macros set the values at that .178 tilt.

 

Haas is faxing the grid shift procedure.

Jimmy,

Here's what i typed up for our table/table Haas's.

code:

 HAAS A/B AXIS ADJUSTMENT PROCEDURE

 

1) PUSH SETTING/GRAPH AND TURN OFF PARAMETER LOCK #7

2) HIT EMERGENCY STOP TO ALLOW NUMBER INPUT

3) TYPE IN NUMBER OF PARAMETER FOR AXIS YOU WANT TO ADJUST. X=210 Y=211 Z=64 A=212 B=213

4) WRITE DOWN OLD VALUE IN BACK OF HAAS MANUAL FOR FUTURE REFERENCE BEFORE CHANGING THE VALUE.

5) ADD OR SUBTRACT TO EXISTING NUMBER AS NEEDED

6) RELEASE EMERGENCY STOP AND PUSH POWER UP/RESTART

7) CHECK WITH INDICATOR AND REPEAT STEPS 2-6 UNTIL DESIRED RESULTS ARE ACHIEVED

8) USE ZERO RETURN ALL TO ZERO MACHINE IF POWER UP/ RESTART DOESN’T ZERO MACHINE AND TAKE THE CHANGES.

Thanks Jim. That was the trick.

 

I will add one thing.

If you go to alarm msgs and type debug and enter you do not have to estop.
