Design and Parts

• Color scheme used for main and accent parts :
  

  

• Controller enclosure is a variant of Jamie’s {TODO:actual name}, details at Jamie's LR4 RC2/RC3 Upgrade - #182 by jamiek
  

  
  • Recommend 0.4mm nozzle for Jamie’s enclosure box. Also, avoid post print Dremel surgery , by checking enclosure will fit gap between braces before you print:
    
    
  • Ended up drilling/dremel/butchering case some more to route light pipes to holes on my Strut.
    I also had to remove some zip tie mounts under jackpot after having resoldered some terminal connectors to bottom of the PCB (which is why my JackPot PCB top looks so clean and RF friendly).
    • Jono shared comprehensive helpful desoldering and resoldering tips.

• Bootstrap Mode

  • Have multiple CNCs, but wanted to test Bootstrap experience. So, I used just 2 small printed temporary struts on left and right side of Beam’s front, successfully carving and cutting 1/4" Ply Struts using these conservative slow EstlCam settings:

after having resoldered some terminal connectors to bottom of the PCB (which is why my JackPot PCB top looks so clean and RF friendly).

So cool! I don’t really have a mastery of this that I feel confident in trying, but it is very cool.

[azab2c]

Thanks @DougJoseph. So, @jono035 shared comprehensive helpful desoldering and resoldering tips, after I shared how much time I burned switching things around

@azab2c

Ended up using dual row 90 degree dupont pin connectors for the endstops, bent slightly less than 90deg before soldering, to help connectors clear adjacent solder joints. My thinking was to help the endstop wires stay within the confined braces (RC2).

Completly unrequired… Was originally planning to orientate JackPot controller board to be visible through polycarbonate window in the front strut. But then Jamie came up with light tube approach, and srcnet suggested a visual of the CNC. The combination of numerous ideas from folks led me to…

Ultimately the Jackpot desoldering/soldering I did wasn’t needed, but does look nice from the top. Am going to baselessly rationalize that I get far superior signal strength to help me feel better about the time burned messing with the board.

[DougJoseph (Doug Joseph (design8studio))]

@azab2c My mind is blown looking at the fact you modified the Jackpot board “by hand.”

I’m now pondering on whether an adaptation of the LED light tubes idea might work for having the LED signals be displayed on the top of the case for the control board. My thinking here may not pan out in the end, but I’ve seen some cases that had hard, shaped, “light fingers” attached to one part of case (in this instance, the lid) that once it was installed, they came against the LEDs.

@DougJoseph

here may not pan out in the end, but

In industry those are called light pipes, and they’re very common.
Clear PETG works, clear TGLASE works, even some “natural” filament works if you have bright LEDs.

@MakerJim

light pipes,

Yes! That’s what I was thinking of.
