Default Cobra ATC spoilboard surfacing procedure

It has been quite some time since I have had to surface my spoil board and I have forgotten the steps. Could someone please provide me with the procedure for a Cobra ATC. Thanks, Mike.

You can make a vectric file that is basically the spoil board size and simply work from material top and cut down .010 or whatever you need.

You can use http://mickmartinwoodworking.com/cnc/cnc-g-code-1/
Micks spoilboard wizard http://mickmartinwoodworking.com/cnc/downloads/

My cabinet software also has a surfacing program to use.

If you mean the tool offsets which now that i think about it.... probably is what you mean. Srry, I'm useless:)

What I am looking for is the process of removing limits, and if and when I have to calibrate switch, and measure tools and putting limits back and making sure that the new spoilboard height does not conflict with my z limit height.

Ah, that 1st link has handy g codes.
1
G49 ( clears offsets )
jog tool to machine bed. leave it there
run spoilboard wizard
jog tool to machine bed
calibrate switch ( this restores the offset )
measure tools ( this restores offset for each tool )

or 2
Surface spoilboard
G49
jog tool to machine bed
calibrate switch
measure tool ( for each tool )

or 3
You can also choose not to measure switch or any of that.
surface the spoilboard a specific amount.
Z0
jog the Z down the amount you took off the spoilboard and Z Zero button

This will make your zero temporary though, but it will work fine as long as you don't hit home, Use the goto xy zero instead.

or 4
surface spoilboard a specific amount. .01 for instance.
M37.3S-.01M1H0 will move all offsets down -.01

M37.3S-.05M1H0 will move all offsets -.05

just use what it takes to clean up your spoilboard and enter the amount of material you removed.

I highly recommend Micks program.
Run program to generate code
Inset surfacing tool-
Touch tool to surface- G49 if it wont go all the way.
Hit go
Load tool 1 and place paper between bit and table until papers is tight.
Drop your z by the thickness of the paper-set accuracy to .001 and drop z-4 times.
Calibrate switch.

Your done.
