Hello glad to be here,Questions about Prusa i3 single-plate "vanilla" Plastics I am brand new here and need help I started compiling parts for my Reprap 3D printer Prusa i3 single-plate "vanilla" I have always been handy with wood or plywood as this case may be.

I have found pictures and videos of the frame but no measurements. Does anyone have them in standard inches or metric. Here is a link that has the picture of what I want.

Your printer is somewhat backwards from 'normal', but hey if it works for you.

Min Endstops should be a X Left, Y platform back and Z Down position.
But thats just the standard way, you can do it in non standard ways, homing to max position etc, but that does make it more complicated.

As for the ramps



Switches are normal wired NO (normally closed) And on the ramps end go to S and - on pin columns 1,3 and 5 (2,4,6 are for Max end stops)
End stop pins are actually labelled X-, Y- and Z- see Image of ramps without components

I am so close to being finished this build . Everything is finished now
I know the wiring for my extruder looks kind of funky but it stays out of the way real nice.
I need to work on the heat bed I have not tightened it down yet that's what I'm going to do next.

my trouble:
I have the mechanical end stops all wired up and ready to install but I am confused of exactly where they go,
Been looking for a picture showing there correct placement but can't seem to locate one.
also a picture of wire coordination of end stops of X Y Z on ramps board.

I will be up late it is 9:24 pm here I will be up untill at least 2 am or better.
I 'll keep looking for a picture, the diagram I have is very general it does not show exact positions.

I built a printer station 24"x 24" secured it to the wall then secured the printer to it with 8 zip ties .
I needed to build a level and plumb station because my work room is not level way off. So this takes the guess work out of whether or not
my printer is sitting level or not. Here is a picture of my printer last night after securing it to my printer station.



Note the blue zip ties that secure the printer to the station.

Blue wire (NC Leg) goes to S

Re endstops. If they are mechanical what ever you do, DONT wire the switches from + to - !!!!! I've seen this all to often lately. The result is a dead voltage regulator on the mega or worse. They are normally wired from S to - in a normally closed manner.]]> Dust New Zealand RepRap User Group Mon, 20 Jan 2014 04:21:55 -0500 https://reprap.org/forum/read.php?41,272430,297929#msg-297929 Re: Hello glad to be here,Questions about Prusa i3 single-plate "vanilla" Plastics https://reprap.org/forum/read.php?41,272430,297929#msg-297929
What I did get done tonight- wired up 3 end stops , wired up the extruder hot end and hot end thermistor.
Wired up the heat bed.

Next to do ; install end stops, install thermistor and LED for heat bed, I will have to look at the wiring diagram that you posted again for the heat bed and LED
thanks for the help

Thanks for the info especially the series diagram for motors 4 and 5

Hi Mar57,
I have a couple of options for you.
You can buy the 4 way DuPont 0.1" connectors from me or you can buy premade jumpers that you can cut and join onto your stepper motor wires.
[www.makershop.co.nz]

When it comes to wiring all that matters is that you wire one coil to the 1A-1B terminals and the other coil to the 2A-2B terminals.
The polarity doesn't matter. If you get it wrong the motor will turn in the wrong direction.
If you reverse either winding or swap the windings around you will change the motor direction.
Reversing the plug also changes the rotation of the motor.
And if that's not enough you can also reverse the motor in the firmware.

Another thing to watch is that the driver can only supply 2A and that is with lots of fan cooling. Your photo shows a motor with a max current rating of 1.2A so you won't be able to plug in the 2 z-axis motors using the 2 connectors on the RAMPS board.
You need to wire the coils of 2 motors in series.

Pololus etc only use 4 wire steppers... so you will need to find out which wire is what.

Your steppers are 6 wires, which with luck are just 4 wires with a centre tap. Like the following image.



You need to find the coil ends.

If your lucky its wired sensibility it would be wires 1,3 as one pair and 4,6 as a second pair.
So get out a multimeter and check the resistance between those pins, are 1 and 3 connected and 4 and 6 connected?

6x 450x100x12mm wood

the wood framed version is normally refered to as the boxframe, and the aluminium framed one is called the single plate version, this may cause some confusion in your research.
