Customizing post processor Mach3

[denis84CYC]

I need to have the Mach3 post processor out-put a G28.1 code which will start a material height sensing sequence on the THC, (Torch Height Control) of our plasma table. This is required at the beginning of each cut before every M03 command throughout a program. Other than that the Fusion Mach3 post processor works well.

Hmmm, how do you need it to work, do you need it to only Probe at the start of a program as in the code below where there are two toolpaths in the same operation.

The program needs to look like the attached file.

Hi @denis84CYC 

there is not enough information to guide you.

Can you please clarify the role of some values?

N0009 Z0.0600
N0010 G28.1 Z0.12
N0011 G92 Z0.0
N0012 G00 Z0.1510
N0013 G92 Z0.0
N0014 Z0.0600

Z0.06 is this the retract height in Fusion?

Z0.12 is this the clearance height or is it a search distance for "probing" equal to twice the retract height?

Z0.1510 What is it?

If we have more information's, it will be easier to give you an answer.

Regards.

Serge, not sure what all the dimensions are for, but the post  has to look like the "5 hole" sample post, if we can get fusion to post like that, in that order, we will be in business. When the plasma torch approaches the stock it rapids to X/Y first, then rapids above the stock a short distance (.25")? then feeds down until it touches the stock and the z axis continues a little further because the torch floats in it's holder. Then the torch is picked up to a specific height where it is turned on and held until a dwell time is expired allowing the material to be pierced. Once the pierce is complete the torch may either drop or lift very slightly to a "cut height" before the torch moves. Then as the torch moves along the cut height is automatically adjusted to allow for stock warp.

Serge, I think the lines N0010 thru N0013 is the probe sequence it goes thru to set the Z "0". Then it goes to Z.06 to pierce, turns the torch on, dwells for a set time depending on thickness, feeds to Z.05 and on to the X and Y moves. As I said earlier it continuously adjusts height as it moves.
