Description

This all-in-one frame mounted backpack Canbus module is designed to be a Canbus network expander & housing unit for a EBB36 toolhead board & SSR for use with the…

TARTARUS Heater Core Module

As well as my remixed Voron Enclosure Top Hat

It will allow easy placement & access to this system on there rear of your machine while keeping the installation neat & tidy & the user safe.

This module is designed for use with 12v/24v/110-220v PTC heating systems that are monitored & controlled by Klipper & that are correctly protected by the appropriate 120ºc thermal fuse. The module uses the PG13.5 cable gland to securely supply power to the SSR & internal Wago 221-413 connectors, then out to the heater core through the upper PG7 cable gland.

The module also allows a PG7 Canbus in connection to the Mellow Canbus Expand board to the internal EBB36 toolhead board via & then secure connections out to additional Canbus nodes on your system like your machine's toolhead.

Printing

Print in ASA/ABS or better to Voron BOM specs.

NOTE: Although I have slightly oversized the printed threads on the TARTARUS Can Module Platform v1.2 model you must expect to chase the threads with either a correct metric thread tap tool or use heat to warm the thread so it will adjust & reform itself to the PG cable gland as you insert it & start threading it into the model! As if not the cable glands most likely WILL NOT FIT CORRECTLY!

DO NOT LEAVE A BAD REVIEW BECAUSE YOU DIDN'T READ THIS & DO WHATS RECOMMENDED ABOVE!!! 

No supports are required on the models apart from the bolt holes on the TARTARUS Can Module Cover v1.2.

Assembly 

Correctly install PG cable glands by using heat to thread, or tap to chase threads.

Install heat set inserts into correct hole on TARTARUS Can Module Platform v1.2

Click 221-413 Wagos into place, they're a tight & secure fit & should snap into place with a little force if your printer is dimensionally accurate & set up well & not over extruding.

Install EBB36 board in the lower central location using the TARTARUS Can Module EBB36 Spacer x2 standoffs & 2 M3 20mm bolts

Install the Mellow Cane Expand board lower right with 2 M3 8mm bolts

install the Omron G3NB-210B-1 DC5-24 Solid state relay (SSR) into the M4 heat set inserts upper left using 2 M4 8mm bolts & washers

Install the 6 roll in T-nuts into the upper rear right corner of the frame of your printer. Using the TARTARUS Can Module Frame Mount v1.0 as a positional guide for the T-nuts.

Slide the TARTARUS Can Module Frame Mount v1.0 under the TARTARUS Can Module Platform v1.2 & insert the 2 M3 14mm countersink bolts into the holes marked “Mount”

Offer the assembly up to the upper rear right corner of your printer & secure the unit in place using the countersink bolts

Proceed with safely wiring up your system taking extreme care when using high voltages for any type of heater!! 

FINAL WIRING IS ON YOU! YOU MUST KNOW WHAT YOU'RE DOING! BE SAFE!

When installing the TARTARUS Can Module Cover v1.2 be sure to use the M3 8mm bolts on the lower left holes either side of the 3 lower PG cable glands!

24v DC Power Wiring

Make sure you PSU has enough headroom to run all parts of the system, the heater & whatever else you're running on the Canbus network.

220/110v AC Power Wiring - DANGER!!

This setup is potentially highly dangerous if done incorrectly or if you go poking about in here when the cover is removed & the printer is powered!

Required EBB36 Connections
