Ensure that 60t gears can be used-- this will involve providing more clearance for the motor-mounts<->skirt (at least 4mm), and probably rounding the edges of the motor.

Looks like the support is offset relative to the z_anchor frame.

The change to the 'z' is in CAD/z/'Z Drive.STEP'
This part is normally "z drive main'
It should be mirrored at least once, and is suitable for use on all feet.

Bed Screws: M3x14 instead of M3x16 (those will collide with the extrusion)

Add Heatset Inserts to MiniAB Motor Frame.

A potential take on this is already in: Micron/CAD/z_probe_endstop/z_nozzle_endstop_short.STEP

Opening git issue as requested on discord. Three of the four A drive upper pieces are missing the extrusion indexing tabs for both the CAD and individual STLs.

The two affiliate links for kits in the readme are both broken at the moment.

Also, I noticed that Funssor has a Micron+ kit available now, should that be linked too?

Fan mount piece is at: cad/skirt/60mm_fan_mount.STEP
There will need to be two, mirrored.

Also need to add the 60mm fan.

f/r skirts have a keyhole-based mounting. Normalize the side-skirts with this and ensure mounting depth is the same.

Already fixed here:

And yet we don't have any places for them.
Seems like providing a place for Wagos would be nice, especially for things going to the bed (AC/DC), and for 24v stuff (lights) in the top.

We need to generate the STLs for the motor covers in the CAD, and the even-more-space variants.

The Z idler body is 18.5mm thick.

With a 20mm screw, you can't get thread engagement on an M3 nut. With a 25mm screw, you can't fit the screw in the slot in the extrusion.

Either it needs to be thicker (say, 2mm) or have a little counterbore (say, 2mm). See pic:

Perhaps make them front-installed instead of from the rear.

It is possible to make it so we can hinge the electronics with the deck panel (like a car trunk), and not just hinge down/out as it does now.

Making this a possibility requires moving the Pi's mounting so that there is sufficient clearance.

This seems to be missing in the repo:

I'm thinking to modify the rear skirt to provide for a cap to the inlet anyway. That could include two variants: one for DC beds, and one for AC beds that has a mount for the BoM SSR.

I think the dock arm will need to be drop down a bit. Roughly 5.5mm. The blower housing crashes into it before hitting the endstop.

Currently these holes are 4.5mm. They should be 4.7mm

Counterbore Z Idlers to be able to use M3x20 BHCS

Alternative: Thicken Z Idler to be able to use M3x25 SHCS without counterbore

Ideally that won't happen.
Looks like the slots for the hinge are longer than they need to be for freely hinging the assembly. Thus, one possible solution is to make that smaller.
Another solution is to have a nub sticking out from the edges that would touch the motor before the PCB of the octopus would.

X Carriage does not work IMHO in current configuration.

I would like to keep M3x8 BHCSs, so decreasing the depth of the counterbore would be the way to go. Alternatively M3x6 BHCS which would be lighter but are not in the BOM yet...

Hi,

What its the minimun layer height I can reach with this printer? I am interested in one printer for layer 0,05 mm or less.. I dont like DLP...

Replace M3x6 SHCS with M3x8 SHCS to reduce BOM.

Only a minor adjustment on the z_drive_base_plate is required.

-This serves as a reminder to myself-

Replace M3x12 SHCS with M3x10 BHCS.

Stepper motor does not have 6mm thread. BHCS because there are no M3x10 SHCS in the BOM.

We don't have a readme in the STLs/Gangry/AB_Drive_units directory which tells folks which set to pick.

On v9 of Micron2.4, the Z belt path goes within the bounds of the frame near the outer edge.

So either the belt needs to be adjusted inwards, and the AB idlers adjusted to match (by ~2-3mm), with the motor kept below the frame...

--OR---

If going direct drive, the motor might "live within the bounds of the frame".

Check this pic, which shows a a 35mm-wide NEMA14 inside the frame. Imagine this on the inside of the frame, towards the right center. The pic also shows the bounding box for the 53mm-wide new MiniAB toolhead. There's ~1mm of clearance as-is, so nothing actually needs to change. I think this is the way to go to test things out (keeping the AB idler). It's much more efficient packaging; otherwise that space is wasted.

The motor would be pointed from the center towards the carriage. So two would be mounted, butt pointing to butt. One is shown in this pic.

Yet what about clearing the bottom of the gantry? Fate... there's clearance already, ~2.5mm or so! There's space already, because the bottom-hanging AB drives need clearance. And there's just enough space to clear those AB drives too, though it'll be tight.

I'm honestly tempted to build a side with the existing parts and just clamp a motor in the position shown, because the mount would be the dumbest, simplest thing every - just an L bracket with holes, to attach to an extrusion.

Separately - you could also change where the Z belt goes through the AB idler, from the inner side of the AB belt idler towards the outer side, and that could give space for a NEMA17 too (needs an extra 3.5mm of motion, since 7mm wider). That motor wouldn't stick out more than the MGN7 carriage already does. So that seems like a good option too. If this was done anyway, you could fit both motor types in easily.

Thoughts on any of these?

spacing is for 120 size, where there is also a 180 version.

Frame Anchor unfinished:

Some screws seem to be missing.

Some are called M3x8 but are actually 12mm.
Some are called M3x12 but are actually 14mm.
