project outline
build a nicer i3 then Printbus. ok this is a joke but at least as nice.
lets face it all stubborn bastards want the best but life keeps it at bay
this project is my way of using free time as i fight stage 4 cancer.
i have never been the time of person to sit still i own a machine shop have 57 employees
and spend every dime i make on my heath and the health of my company and the family's involved with it

steps. order things will be Done

1. recreate the printer in solidworks to within ±.05mm from parts apx 2days based on free time
2. build main frame and test all fit
3. prep main frame for automotive grade paint job and Pinstriping :-P
4. send to paint
5. start building all other base components sand clean a paint
6. take aluminum parts to work for Electropolishing and maybe copper-nickel plating
7. replace most hardware with stainless Hex hardware if needed
8. pickup main frame, clean, wet sand, polish, then glaze to perfection
9. completely build finished printer without electronics
10. plan then re plan all wiring
11. install wiring with quick connects
12. test printer
13. install auto bed leveling (ABL from now on)
14. retest printer
15. test part eject script and part scraper
16. install custom dual Z max end stop controller and external driver for independent z control
17. test custom auto gantry leveling system
18. retest printer
19. Install in custom built home with full environment control system.
20. test at control environment temps
21. test custom built Octoprint
22. Complete add printer to 3dhubs
23. use to build prototype parts for mega print&cut by TMJ
24. use mega Print&Cut to build body for custom built "shell ECO Car" named 2for1
25. (bodyless testing 1547.3mpg avg at 40mph with 2 people in it me and my bag = 430lbs rider weight)

take lots of photos along the way
share teaser photos of custom 5ft by 9ft by 4ft printer / router I'm building aka Mega Print/Cut or "MPC unit" they are linkable

First Major Update:
Kit is here all parts accounted for
Wire is here waiting for PCB from OshPark (ATX PC PSU control board)
and 2mm acme TR8*12 and anti-backlash nuts ETA 3days
picked up fender washers for all the m5 bolts it needed them bad
finished layer change firmware mod (moves head and toggles snap shot at a settable Z points triggers by gcode Z not head location so ABL can't false trigger it)

parts removed from panels and lightly sanded
built frame just to check fit then pulled apart to have painted
Main frame parts dropped off for pro paint job
Colors to be used will be Black with Orange Trim
most parts will be color matched spray paint simply because i don't want to wait..
most of the CAD is done
hotend built, X brackets painted & built, got alu parts ready for work tomorrow (polishing).
started laying out the wiring , using DEANS micro 4pins at the Extruders & X axis steppers
using 2 pin micro Deans at the end-stops, and spiral wire wrap over the cables.
gantry using real cable carriers from igus (ID 25mm H X 38mm W | 100mm bend Radius B15-038-100) and 3mm id tubing to feed filament
from base so nothing simply hangs it's a near full closed loop will be installed after the fact (using printer to make mounts)

ok guys my only real day off is Sunday so next update is a hand toss. if you have any ideas please let them be heard.
stay on or off topic i don't mind

I'm looking forward to step #15, as that is the point where I am at now. I can do everything on my printer remotely except clean off ooze, replace filament, and clear the printbed ready for another print.

I'm looking forward to step #15, as that is the point where I am at now. I can do everything on my printer remotely except clean off ooze, replace filament, and clear the printbed ready for another print.

ooze i take care of with a simple servo, an arm and a python script on the pi
but i will be adding a custom g code to marlin soon to take over this job

filament is best delt with by changing to dual or multi-extruder setup and adding filament sensors 95% of the code is in marlin as is
print bed is another can of worms i picked up a higher torque 72mm long nema 17 (122oz) and a 16 tooth pulley for Y bed
the printer will be bolted to 3/4in thick MDF just to make it less prone to twisting when it starts pushing parts off
the scraper is nothing more then 1/8in 7075-t6 bolted to the back of the gantry that sits about 1mm above the print head
i plan on making it so the print head is off glass at home X just a tad so i can bring it all the way down if that makes sense

this scraper gives me a good place for a strip of LEDS to back-light the gantry, and makes the gantry rock solid.
the rest is just a simple end gcode script.

I hate to do it... I know this thread is a bit old.. but I have to know Did you ever finish this?? I'd love to see the pictures! It sounds amazing.

[sniffle]

A bit old? Nah all the mods hes doing and in his free time hes probably still writing code :-)

He'll update when hes able
