A1 Mini Auto-Plate-Changer rework 4 AMS top mount

Hello to A1 Mini Community,

this is my first upload :)

UPDATE V1.2 OUT NOW! 

• added magnet inserts for up to 8x3mm magnets (2 for each plate)

UPDATE V1.1 OUT NOW! 

• changed plate tray and plate gripper (if you have printed the mods, you only need to print plate 1 and 2)
• gcode change

Here are all the changes listed:

(plate tray)

• highten by 20mm for more plates
• widen by 1mm for better clearance while pulling
• shorten the alignment dents for better positioning
• added an indent on the alignments for smoother “drop”
• added a slight angle at the front of the platecarrier for better alignment when the plate drops in place (marked as V4)
• changed the positioning hight of the platecarrier to prevent the current printingplate from getting stuck on the loaded plates, which results in a wrong Y-endstop position (marked as V4)
• added magnet inserts for up to 8x3mm magnets (you need 2 magnets for each plate - slide one in from the back and attach one from the bottom) (marked as V4)

(plate gripper)

• scale to 101% (mine were a slight bit to tight and wont grip the plate properly)
• changed the hight of the left and right gripper to accommodate for the new carrierhight (marked as V1)

(y cable cover)

• longen the tail for better cover (the original one is to short, my cable still liftet the plate)
• (I later went for a modded drag chain for aesthetic reasons as seen in the pictures but this thing still worked flawlessly)

(top mount 4 AMS)

>this is the main reason I publish my models. I really liked the work by Nii but still wanted my AMS on the Z post mounted for space reasons. But the original mounting plate does not fit over the AMS top mount, so I had to find a solution. :)

• remix of the AMS holder to one part, shorten it slightly and elongated the front screw hole
• added a spacer plate to fit in between the z post and AMS holder
• added a cable guide for AMS cable

(top mount NOT 4 AMS)

>this is just for those, who might want a stronger (screwed in) top mount 

• cut off the AMS mount
• removed the cable guide for AMS cable

(AMS cable cover) (this is not a remix, but it fits into this project, so I just added it)

• covers ams cable and ptfe tube and locks them in place.
• mounts to the original filament holder holes (thats why this does not work without AMS)

ADDITIONAL NOTES!

!!! Due to the changes on the plate trays you need a different gcode !!! (otherwise the plate will just fall out)

Screws:

+ 3x Cap bolt M3x20 for the top mount (same for AMS and without)

+ 2x Cap bolt M3x8 for the cable guide

Magnets:

+ 4x Neodym magnet up to 8x3mm size (I recommend 8x3mm)

I hope, I listed everything. :D

If i have to do edits, i will change the things above and additionally list them explicitly below. So if you come back later, you will have a detailed list of stuff, that changed.

Only one thing left to say is:

HAPPY MODDING :)
