Cable length
Hey,
While I'm waiting for my MK2S kit to arrive, I'm designing an enclosure for the printer (great way to learn how Fusion 360 works, right?) 🙂
I plan on placing the PSU and motherboard outside of the enclosure, and then make a hole in the backplate to route the cables outside.
But I was wondering - does anyone have the length of the different cables the printer uses? (So I can make sure they are long enough to reach). 😀
Also, I plan on having 2 120mm fans in the enclosure, one for moving air in, and another to move the air out - is that overkill? And will it cause problems with ABS printing?
Re: Cable length
Not recommended to not have the PSU attached to the unit. The PSU provides the structural support for the Z-Axis to keep it squarely aligned. If your worrying about heat inside the enclosure, you can put a fan system to pull the hot air out of the enclosure. I am almost ready to post my HEPA Filter on Thingiverse and you may like it, or you may not. There are plenty on Thingiverse to choose from. If you want to check my profile there over the next week or so, I should have it up soon if your interested in mine. My goal on my design was to minize the footprint inside of the enclosure and pull the air through the HEPA filter instead of doing what others have done which is push it through the HEPA filter. Also, it can be installed on various wall thicknesses of the enclosure.
Re: Cable length
I plan on printing some support structure for both sides (where the motherboard and PSU are attached), that connect to the holes they are normally attached to, and then connect it to the base of the enclosure (with some support of course - think of a 90 degree triangle).
That way I can bolt it down, which should keep it in place, and prevent vibrations.
In case printed parts won't do it, I could always go for a wooden support structure.
Won't it fix that part of the problem?
Re: Cable length
Don't have to worry about the Rambo case, it doesn't attach to the Y-Axis, just the frame.
As long as you have a plan to connect the PSU side to the frame with a different support structure, you should be fine.
Now as for the cable length, that I do not know. Do you plan on having the extruder cable connect to the rear of the enclosure? If so, you may want to re-think that plan a bit. The cabling is designed to go to the left to the Rambo board. Moving directly behind or behind and up could cause some binding issues. May be better to have the PSU on the rear and the Rambo board to the left side of the enclosure so you still have that designed bend of the cabling.
Re: Cable length
I plan on adding cable chains, and then adding a "connector" to the support structure that goes where the motherboard would normally be.
That way, I should be able to use the normal cable chains people use, and then just run the cables out from where the motherboard used to be 🙂 (Which is what led me to wonder how long the cables are in the first place)
