UPDATE:

The original cover was not working reliably enough, so I simply extended the original apron LED cover to a 8N version. The original version will still be available, but I recommend the more sturdy one. The pictures are still from the old design, but the new one is self-explaining.

Original version:

I just finished my build of the ERCF V2 with ERCT and completely messed up the LEDs on the Coupler Blocks (see last picture).

The provided elements are pretty flimsy and also ignore any printing and mounting tolerances, which causes the original carriers to break.

The model is designed for 8 gates and uses the original spacing of the neopixel LEDs. Solder them as you regularily would with the solering jig from the ERCT files (spacing 23.05 mm).

Print my parts:

1x ERCT_LED_8N.stl (ABS primary or accent color, no supports, 3 mm brim, print upright for more stability, ERCF/Voron settings)

min. 2x ERCT_LED_Adapter.stl (ABS primary or accent color, ERCF/Voron settings) → I used 3 adapters.

1x Apron_LED_Cover.stl (Multimaterial, ERCF/Voron settings)

Print the first 1 mm of the Cover in transparent PETG (or an equivalent material), the rest will be printed in black ABS.

PETG and ABS will bond well enough to make a permanent solid part.

Assembly:

Clean the brim from the main part (ERCF_LED_8N).

Gently push your already soldered LEDs in the main part. Make sure that they are straight and not crooked. Feed the cables through the cutout on the controller box side.

Slide at least 2 adaptors in the V-slot of the main part. The notch faces upwards as in the original parts of the ERCT.

Align the adaptors with the slots in your coupler blocks. You can slide them into position, which also allows you to get rid of any assembly tolerances. Push everything in position.

TEST YOUR LEDS NOW!

If everything is tested and ok, push in the cover. Adjust the position of the whole assembly to fit your liking.

Enjoy a stable and straight LED-stripe on the coupler blocks of your newly built or retrofitted ERCT.

 

The multimaterial part con be printed with a simple color change at 1 mm height. You don't need a MMU for this print, but obviously you have a MMU and want to use it for this print.
