G43 ignored
« on: October 16, 2012, 05:47:24 AM »
Hi Everyone,
I'm trying to get "stop spindle, wait for cycle start" to work properly.
It's selected in config
The M6start macro is still blank and the M6end macro is untouched and just returns xyz if they have been altered.
The program runs OK, stopping to allow a manual tool change and continuing when "cycle start" is pressed

here is my code

N02 M6 T1
N03 S4000 M03
N04 G4 P5
N05 G00 G90 G54 X0. Y0.
N06 G43 H1 Z2.54 M08
N07 G81 G98 X0. Y0. Z-4.871 R2.54 F400.
N08 M09
N09 M05

The tool number "T" does not change from zero and the tool offset "h" is unaltered..........why

stay calm folks

Do you have the height offset set in the tool table?

Can you attach your xml and aslo your code.
Oh and I think the tool number display part is broken but the height offsets should be changing fine.

Hi, how can I give you the XML file. I could email?

Ok just had a look at the original screenset and the DROs for tool number and height offset dont change so seem to be broke. However  the Z DRO does, can you confirm if yours does or  not change to refect the height offset.

I haven't used forums very much so it's slow progress for me.

I put together the gcode using Bobcam. It also has a tool table. The following table shows a program for drilling 4 holes of different diameters through the same thickness plate.
I'm not quite sure why the Z is different for each of the 4 drill operations. I know this is a different question but a little help here might enable me to answer you more accurately.





(BEGIN PREDATOR NC HEADER)
(MACH_FILE=3AXVMILL_MM.MCH)
(MTOOL T1 S1 D2. H127. DIAM_OFFSET 1 = 1.)
(MTOOL T2 S1 D4. H127. DIAM_OFFSET 2 = 2.)
(MTOOL T3 S1 D6. H127. DIAM_OFFSET 3 = 3.)
(MTOOL T4 S1 D8. H127. DIAM_OFFSET 4 = 4.)
(SBOX X0. Y0. Z-25.4 L62.155 W0. H0.)

The deth of cut (z) is different because the larger the diameter the drill is the LONGER the leadin for the point is and you have to drill deeper to account for the extra length back to the guage point. Tha way you have a hole ALL the way through the material.

Just a thought, (;-) TP

Ok as a test  zero your Z Axis DRO then go to MDI page and type G43H1 and press enter and see if the Z Dro changes, Next type G43H2 and enter and see if it changes, G43H3 and enter and see if it changes.
If it doesnt then sounds to me like your tooltable in Mach is not set up, if it is then I will get you to attach your xml, I will explain how to if the need arises.
