Working with a beastly hardware kit.

[Treak]

After hitting my first brick wall with the stepper motors. I got rid of the xbox power supply and moved on the ones already inside the machine. 2 of the 3 PSU's connected and all the fans + lights i have available in the machine. I plan on making a line filler box when i add the 240v PSU for the chamber/extruder heaters. Originally i wanted to go to the department store and make the filler box out of sheet metal and screws. I wanted to explore a team collaboration for creating parts and i am able to invite people to the grabcad workbench for being an adopter. If you use solidworks PM me your email and ill toss you an invite link with max powers for those who want to play with it.


The box will have...


1. USB plugged into the rambo (or ramps, whichever i get working first)
2. Main Power (computer style plug in)
3. 12V 2A Fuse
4. 24V 6A fuse
5. 120V 3.15A fuse
6. Respective trouble shooting leds/Test points


Below is a picture of my "just get it working" power set up

The lights/blowers are all direct independent power from the 24V PSU, and running a bit high but not worrysome. I plan on adding in line resistors to tune all the blower fans output even through it may not be necessary.

I reinstalled the original SBC and connected the LCD, hard drive and PSU but it did not budge when i flipped the switch. I am having trouble finding anything about this lcd. It would be nice to connect it to the rambo or ramps if possible.

Moving on to the electronics, the thing that makes this a printer and not a heated brick with fans and lights.

Only the 12 volt is connected to the rambo using this diagram. i connected everything with the information i have at hand and my best guess for the stepper motors (each of the stepper lead pairs are isolated and connected to their respective pins but the position is a crap shoot)

(I hear the rambo board can go to 24v but im not so sure about this china made one the picture with 12v down the line for power input made me lose confidence in putting 24v into it.)


There are two types of temperature reading devicdes that normally have some sort of signel amplification. But today we are using electric tape for the chamber sensor which appears to be just a wire stick poking inside.

The other is a thermocouple and the only thing i know about that is the name, Thick as hell wires go into i and communicates with PWM.
