I really had no plan on documenting this build mostly because I had no real plan. All I knew was what I wanted.
It had to be big i ended up choosing 1000mm x 1500mm x 800.
I wanted to do everything 3d printing, routing, aluminum milling, lazer engraving.
And I wanted it to be fun.
So i begun the work by trying different rail set ups. The reason i went with the dual rails was for pure stability. Wanting to do 3d printing i wanted to have more then a couple inches of z.
I used c beam for my z legs using 8mm lead screws. On both sides to drive the gantry up and down.
Everything else is using gt3 belts and i intend to use nema 23s or bigger
The rail hanging from the wall is going to carry all the cable and tubing for the gantry
It can sway and there will be a small slide on the rail.
The electrical is planned with multiple metal boxes and break outs. Here are some pictures , keep in mind im still lacking the majority of electronics.
Herr is a 12v power supply with a ac line filter on it.
This is my main box it will hold the brain board that will break out into my motor and endstop boxes.
A 24 pin plug will come into the box then run into barrier diodes break out to the motors everything is shielded and grounded. Here is the 24 pin cable.
I stripped and pulled back the grounds and used some braided copper to connect them.
I put heat resistan sleave on each set of 2 as well as heat shrink. Then soldered them to the plug.
I put a large ferrite core around then end for extra protection. After wrapping electrical tape to make a stop i put heat shrink over it.
I have a 2.2kw spindle but without 220v i have to run it witch will be in the future.
Im going to try a pc water cooling system for the spindle.
I have a vacuum pump and a air venture for a vacume table system that im building here id a vacuume pad as well as my selenoids
And the endstops i chose
The end stop box will be alot like the motor box just with opto couples instead of diodes.
This is a few pictures of my hotends for when i 3d print.
This is all i can really think about right now. If anyone has questions please ask.
