Wow, that sherpa mini certainly appears to share a common ancestry with mrac1's extruder. I don't know which one came first, but having so many similarities allows people like us to enjoy the advantages of both.

The sherpa mini was the first. When I printed it, I noticed that the shaft of the 50 tooth gear grinds on the motor housing. Therefore, I have completely redrawn it. Because of the given Bondtech parts and the motor, there are not many possibilities for the design. Apart from that, the Sherpa mini is very nice and I wanted to get as close as possible to the look with my version.

@Hergonoway the 64 mm rod spacing comes from my first design without smarteffector: https://www.thingiverse.com/thing:3609378
And yes, it should also look as good as possible

The two 40x10 fans work extremely well! However, it also took many attempts until the air flow was right.

@garyd9 Print quality is a bit better than my Prusa MK3s.

There isn't much room for nuts and my first version, as I said, simply screws directly into the plastic.

Here are my values:

M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
M92 X200.00 Y200.00 Z200.00 E709 ; set steps per mm
M566 X1200 Y1200.00 Z1200.00 E600.00 ; set maximum instantaneous speed changes (mm/min)
M203 X18000.00 Y18000.00 Z18000.00 E4800.00 ; set maximum speeds (mm/min)
M201 X3000.00 Y3000.00 Z3000.00 E4000.00 ; set accelerations (mm/s^2)
M204 P1250 T3000 ; set print and travel accelerations (mm/s^2)
M906 X1000 Y1000 Z1000 E370 I40 ; set motor currents (mA) and motor idle factor in per cent

In my files, I'm calling it "mrac1 mini extruder", so I agree that it needs a name.

Sounds good

In my files I call it D3E (DeltaDirectDriveExtruder)

The extruder's plastic was in the way of the little latch on the connector. (Below are images of the area I'm referring to.)

You are right, it's to tight there. On my Deltas I'm using my first version without brass inserts.
At this point you could take away some material without getting problems with the inserts, I think. Otherwise - it also works if the screws are simply screwed into the plastic. Then there is enough space at that point.

Assuming that theoretical work is accurate (or close to accurate), the effector from mrac1 has a much lower stability of ~134.94. (64^2 / 30.354)

I am reprinting my effector, this time with 82 (rod space) to 18,257 ("b" value). So "TES" = 368.3. Thanks again for the article and your work. I'm very curious if anything changes (I think levelling should be the best way to tell).
