A4T side-car PUG mount, toolhead board, xt30 angled plug and support strut

This model contains 3 mods to A4T you can pick and choose from

1. Sidecar PUG Mount for A4T+WWBMG

I wanted to use PUG with my A4T on a Trident but I wanted something rigid and with minimum use of z-height about the toolhead. I created a "sidecar" mount which squeezes into a bit of unused space to the left of the toolhead, sandwiched between the pcb board mount and the extruder motor plate. 

This design seems pretty rigid in my testing so far

I designed it to work with A4T + WWBMG Extruder + Fysetc H36, though I expect it will work with other toolhead boards as well

BOM

• 2 Voron heat inserts

• 4 x M3 8-12mm for securing PCB to toolhead mount and also securing toolhead mount to brass spacers

• M2 or M2.5:

  • heat insert x 2

  • bolts to match 12-14mm x 2

  • these secure the pug, cable tie version available on request

• little bit of superglue or epoxy (optional)

• M3 x 6 countersunk bolt for retaining piano wire if using "pug clip piano" part only

Printed Parts

• toolhead board washer x 2

• pug holder (supports needed)

• new motor plate

• pug clip piano OR pug clip. (piano version has hole 

• toolhead board v2

Assembly

1. (optional) Glue the toolhead board to the pug holder

2. add 2 M3 heat inserts to the toolhead board + pug holder assembly for the PCB mounting. The one on your glued joint can be inserted deep to help bond the parts together

3. add 2 M2/2.5 heat inserts to the pug holder

4. assemble WWBMG extruder with new motor plate

5. with extruder motor installed, add the brass spacers and then mount the toolhead board.

6. mount the toolhead board with 2 M3 screws

7. mount the PCB, add the printed washers to standoff the PCB from the printed mount

8. run your wire to the pug and secure with the pug clip and M2/2.5 screws

9. cable ties, lots of cable ties

Note the toolhead board also has a mount to secure the hot end wires/ferules and provide some strain relieve. Can be removed in the slicer if you prefer

2. Support Strut for Cartographer CNC mount

Many toolhead boards have a 3rd mounting lug, but the Cartographer CNC mount doesn't have this mounting point

This support strut provides this mounting position

BOM

• 3x Voron M3 heat inserts

• M3 x 12mm x 2 button head - replaces the M3 x 8mm button heads used in the top mounts of the A4T cowling

• M3 x 12-14mm x 2 socket or button head - used for the 3rd mounting point

Printed Parts

• support strut tapered bolt x 2

• support strut body

• support strut tool

Assembly

• add heat inserts carefully to the 2 support strut tapered bolts

• switch your A4T's top mounting bolts for M3 x 12mm

• position the support strut body in place, can be hard to get in once full toolhead is attached

• mount your toolhead, M3 thread will stick out from your CNC mount, this is what the tapered bolts attach to

• twist the  tapered bolts into position using the tool as needed

• mount the toolhead board to the central hole

3. Angled XT30 plug

I didn't want my umbilical sticking up in the air then having to make a 270 degree twisting turning route to the PUG

So I cut off the end, printed this, and soldered my own

BOM

• Existing umbilical cable - e.g. Fysetc or BIQU or wire of your choice

• XT30 2+2 female plug with crimps

• Lots of 2mm cable ties

Printed Parts

• xt30 plug top

• xt30 plug outer - print with lots of supports

Assembly self explanatory
