Z-Shift

[Anonymous]

Would it be possible to change the post so that it puts a Z-shift in the program?

That way the operator could enter the thickness of the wasteboard or easily make slight adjusments to the depth.

This is what mastercam gives us for our thermwood router:

(Material Thickness)
SET THICK1=0.675

(Fixture Height)
SET FIXTURE1=0.500

[ZSHIFT=THICK+FIXTURE]

Thanks,

Does the Thermwood understand the ZSHIFT command like that? Nothing more to change to the code than those lines?

Yup, I coppied that directly from an NC file.

Is this something that would be hard to do?

[Laurens-3DTechDraw]

No it's quite easy actually.

That's good to hear,

Could you explain how to do it?

I don't have a lot of experience customizing post processors

Thanks

To keep it all easy I made a post for you.

From the generic Thermwood.

What is new in there are two post processor properties. aThickness and aFixtureHeight.

You can set them during post processing if you already have an idea what the operator will fill in. If you don't leave them at the default 0.

And it will now always give you this code:

G90 G94 G40
G990
M48
G96
G17
G71
G805 (Acceleration Macro)
G9 F1 (Tangency Factor)

(Material Thickness)
SET THICK1=0
(Fixture Height)
SET FIXTURE1=0

[ZSHIFT=THICK+FIXTURE]

M5
G46
G990
G0 Z0.
