Could use some help with my Delta-Pi 3D printer

Former Member

Hello Element14 community,

 

I watched a couple of ben heck videos on youtube lately and that inspired me to sign up at this website. I'm not sure if it's ok for me to just start a discussion as a new user but i'm going to give it a try.

 

I'm currently building a Delta-Pi 3D printer (http://www.thingiverse.com/thing:53708) and it's all going quite well when it comes to the non electronics. I have the base all set up and the plastic parts are mounted with the motors etc.. The problem that i'm currently facing (and not looking forward to) is the electronics part.

 

The kit that I bought came with a sanguinololu with 4 chips on it + a larger chip. I honestly don't know what these do but from looking at some pictures on google I was able to insert the chips the correct way(?).

 

Next up i'm supposed to start hooking up the power, heatbed and extruder to a power supply. I've found a reference .svg that explains quite a lot but i'm stuck on some parts. (THE SVG)

 

As you can see on the .svg I have to hook up the heatbed and extruder by 2 cables onto the sanguinololu but then they split up in 2 individual cables at the end making it 4 that connect to the sanguinololu. I'm very confused about how I should do this.

 

The other confusing thing that i'm facing is the fact that I only use 4 motors (3 for the beams + 1 for the geared extruder) instead of the 5 that are shown on the .svg. It also shows a couple of black clicky things (3 on the .svg). I do have those but i'm not certain as to where i'm supposed to place these? Finally i'm wondering what the tiny blue pcb is that is shown on the .svg that connects to 2 of the motors. I do have a small black block with some pins that might be it? It says ROYAL JQC-3F-DC12V on it.

 

You might have noticed by now that i'm a bit of a novice when it comes to electronics. I've had some experience with soldering arduino components in the past and I do know how to solder but I could really use some help.

 

Thank you for taking the time to look at my discussion and thank you in advance for any advice!

    Hey Remco

    Good to see your getting into 3d pritning.  So the 4 chips your talking about is the stepper drivers(http://reprap.org/wiki/Pololu_stepper_driver_board)  The large chip is your Atmel which will get the firmware loaded onto it.  Hooking up the heatbed and hotend you will connect the power from the heatbed to 2 wires for the board(sanguinololu)  same goes for negative on heatbed.  Repeat this for the hotend.  Having 4 motors isnt going to be a problem as all you will be doing is eliminating the board that is shown in the picture.  Follow this link for a wiring schematic with 4 motors. http://www.open-electronics.org/a-new-board-for-the-3drag-theres-more-than-sanguinololu/.   The black switches you see are what is called endstops.  These are used to tell the printer what is home or 0.   Hope this helps
