Question X3 Tool Change

I am trying to use my X3 with fusion but I can not figure out why it turns on T3 then deploys and then turns it off then switches back to T1. I want T3 to surface material and T1 to do the rest. I am using the Post Process File from Fusion website. Here is my code. Thanks for any help

Post your post processor. I bet somebody will spot the reason.

I used Fusion for a while, but imported the parts to vcarve to do toolpathing. A pain, for sure.

This is the 1st part of your tap file.
I added the stuff in () so you could see what I'm guessing at.

N10 G90 (Absolute coordinates mode)
N12 G20 (set to inches )
N14 G53 (raizes Z all the way up)
[T3 flat end mill DIAMETER = 2.5 ]
N16 T3
N18 S18000 (set spindle speed at 18000)
N20 M3 ( turns on spindle )
N22 M37 T3 ( this one confuses me. Does the machine try to measure the tool at this point? That's what this is for, to set the bit offset.)

N24 G0 X49.625 Y1.0138
N26 G43
N28 G0 Z0.6
N30 G0 Z0.2
N32 G1 Z0.032 F150

Here is a bit of my gcode
N10 [Material=3/4 Plywood W=48 L=96]
N15 G90 ( absolute mode)
N20 M5 (spindle off)
N25 G53 Z0 ( home )
N30 [1/4 Downshear] ( calling for tool)
N35 G4 [Hit Enter to Continue] ( M37 macro running here)
N40 T3 [GET TOOL NUMBER 3] ( still M37 macro measuring tool offset)
N50 M3 [SPINDLE ON] ( now the spindle turns on.
N55 G53 Z0 ( home )
N70 G00X26.9978Y31.7579Z1.2500 ( Actually cutting)
N75 G00Z1.0000
N80 G01Z0.7500F75

You need to remove the "M3" in line 11 of your post processor. The X-3 does not use the M3, it uses T1, T2, and T3 to turn on the spindle and set the tool offsets.
