I does not appear that I fixed it successfully 
When you have a chance I think that there are two things worth trying.
The first is to give the latest calibration process a try.
Note that successive runs now improve on each-other so it could be worth running it a second time even if the first one doesnāt go right.
Second @WFD created a fantastic spreadsheet which can do the calibration math using the data from a calibration run which seems to give results in cases where my math is breaking down. That could work if my math doesnāt
Can I upgrade to the new firmware and not the index file and the yaml or should you do all at once?

you must do the index and firmware at the same time. after you get onto current
firmware, you should not have to touch the yaml file directly.

So this is supposed to make a 40mm square in 200mm and up 200mm, than a 100mm diameter circle.
Fusion simulation looks good
NC Viewer 1.1.3 looks good
Well that foam bit is toast. In all itās spark oh shoot glory.
Now the interesting piece here. After pulling the plug and looking at the coordinates reported by fluidNC. What is expected by the gcode is not correct. Why in the heck would it report -28.12 when the total negative value is Z-3.175

Since Iām a glutton for punishment, letās have another go. G54 is getting set.
I think I figured it out. Line 7 of the gcode G28 G91 Z0.

(T1 D=6.35 CR=0 - ZMIN=-3.175 - flat end mill)
G90 (Absolute positioning)
G17 (XY plane)
G21 (Set to metric system of units)
G28 G91 Z0 (Move straight to the reference position relative to the tool's position)

I have to pull the arms back off as the second from the top got wrapped in the gears againā¦
What I think is happening here is on a normal gantry machine you run a homing cycle. Well, Maslow doesnāt have a homing cycle defined. $H actually throws an error. When a user jogs to the start point and sets G54 relative to the machine position.
On Maslow you automatically assume you start with Z all the way down. There are no limit switches, so this is the work around to āhomingā. If āhomeā with Z down, add slack to pull pins and load the router bit, and set the router height using a 123 block. Iām now 28.5mm positive, well I canāt go to Z0 relative to my current position without driving my endmill 28.5mm negative into certain death.
So in this case to the TLO would need to be set G43.1 Z28.5. It doesnāt look like Maslow supports G43.1 or $#.
@bar does that make sense?

I think so? You might know more about this than I do. I just press the define home button in the z-axis popup at the top surface of the material and that usually works, but there might be more complicated situations that Iām not aware of which might not behave as expected
I got to digging into the post processors. I know you said it didnāt matter any grbl one would work, but I donāt think that is the case here. I see allowHelicalMoves is set to false on the maslow one. If this is grbl version 1.1 helical moves are supported through G2 and G3 commands.
The starting output from the maslow one is quite different.

Oh wow. I hope helical and trochoidal moves get implemented these are key to saving bits, carving 3D and when working with anything other than wood.

I expect that the maslow one is based on the old maslow firmware capabilities,
the maslow 4 is based on fluidnc and is FAR smarter than the older generations
of machines.

So I updated allowHelicalMoves = true; on my maslow post processor and exported this gcode. So maslow is running at least 1.1 grbl as there are G2 & G3 commands present.

Here is what I ended up measuring towards the end of the work area. The square came out great, but the circle is shy of 100mm if I added that right.

Understood, I just saw it was updated 41 days ago. Hey at least we can get it updated to include helical moves.

It would be better to fork it and make a maslow 4 profile (or find a fluidnc
profile and use that), there are still the old maslow machines around, we donāt
want to break them.

Well off to the races I go. Hoping 3" from the end of the ply will be okay. Suppose Iāll find out soon enough.

Bold first cut!
Yeah, I need to be able to do full size sheets. I think Iāll have to make some blanks that I can slide in along the edges to allow Maslow to get closer to the ends.

@bar with the vacuum on it almost functions as a vacuum table holding the router to the work piece. The whole work piece flexes.

This makes me wonder If I should have the Vac on during calibration as well. since its going to add to the resistance.

Fusion estimated 3.5 hours. 5 hours later, Iāll have to setup a machine profile to dial that estimate in. I canāt cut the tabs free at the moment, but it looks pretty darn close to fitting.
