This is a simple, compact MAM designed to start producing shapes as quickly as possible, and not get stuck or delayed when changing shapes.

It creates four belts of output and supports all colors, with up to four layers per output shape.
Pins and crystals are not supported.

UPDATE: version with PINS available here:

The pins version has an additional input rail that needs to bring in one wagon of 'raw' pins on all floors (ie a shape that has four pins and nothing else)

Edit the signal in the top right corner to change what shape is produced. You can enable/disable the MAM with the ENABLE button (note default is ENABLED)

The MAM expects two input rails, one for paint and one for base shapes.

As long as you have enough trains and input resources, you should be able to support at least 3 MAMs using the same rails.



The paint train needs to have one wagon if you are using the 'with pins' version of the MAM, and two wagons if using the 'no pins version'. Each with the following paint:

Wagon 1:
1st floor: Red
2nd floor: Green
3rd floor: Blue

Wagon 2 (no pins version only):
1st floor: Red
2nd floor: Green
3rd floor: Blue


The base shapes train needs to have four wagons each with the following complete base shapes:

Wagon 1:
1st floor: Squares
2nd floor: Squares (optional)
3rd floor: Squares (optional)

Wagon 2:
1st floor: Circles
2nd floor: Circles (optional)
3rd floor: Circles (optional)

Wagon 3:
1st floor: Stars
2nd floor: Stars (optional)
3rd floor: Stars (optional)

Wagon 3:
1st floor: Fans/Windmills
2nd floor: Fans/Windmills (optional)
3rd floor: Fans/Windmills (optional)

If you have unlocked multiple trains, you can use the 'filler wagons' to create 4-wagon trains that only bring in one base shape, as shown in the screenshot.


If you are using the version that adds pins, you also need a one-wagon train that brings in 'raw pins' (ie a one-layer shape where each corner is just a pin)

Wagon 1:
1st floor: Raw pins
2nd floor: Raw pins (optional)
3rd floor: Raw pins (optional)

Shapes flow from top-to-bottom in the following images.


The first platform multiplexes the input shapes from the four input train stations and selects the base shape in the current layer - one for each quarter, if a particular quarter-shape of that type is required in the layer.



The next three platforms apply the seven paint colors





The next platform cuts the single input line into four quarter-shape lines.

Any incorrect quarter-shapes left over from a previously selected design are trashed



The next platform merges quarter-shapes into half-shapes, if required

Any incorrect quarter-shapes left over from a previously selected design are trashed



The next platform merges half-shapes into a single layer, if required

Any incorrect half-shapes left over from a previously selected design are trashed



The next platform merges on top of the lower layers in the shape, if required

Any incorrect layers left over from a previously selected design are trashed before merging



Finally, the completed shape is checked against the required design before sending to the output station.
