Printrbot 2.0 Derived + 20x4 LCD Controller (WIP) by openhardwarecoza Oct 14, 2012

Description

A newer generation Printrbot put together from some of the best upgrades available on Thingiverse, with some of my own parts thrown into the mix (e.g. Bearing Guide compatible with GT2.5 32 teeth pulleys) and my Left Side panel (used to neaten wiring using a DB25 wiring loom. The connector Plate mounted to my electronic's enclosure is included too ).

Also included (Beware W.I.P) is a box for a SD breakout, 20x4 LCD, buttons and rotary encoder - we are busy getting hostless printing with Repetier, running on Generation 7 electronics. Will upload as soon as Eagle files etc have been tested.

EDIT: 19 Oct 2012
Abondaning the first LCD Case.

Made a newer narrower,wider PCB (eagle files uploaded here now) with buttons instead of rotary encoder. The encoder doesnt work over i2c, and needs direct MCU buttons - which I can't sacrifice at the moment.

Ok, thanks for the help.

 I'm afraid your printer needs some recalibration.   Use Prusa's Calculator to check your x/y steps against what the calculator says you should have for your belt/pulley combination.

Hi i'm currently printing the parts and I was wondering how do I Z linear bearings stay in place, as mine don't have enough interference to stop them falling through.

Thanks

Instructions

Print

Replace parts on your Printrbot or build a new one

Extras:

- Proper 32 teeth GT2.5 Pulleys and belts (no printed pulleys - as they don't work so well)
- J-Head hotend
- Extruder: I recommend the thingiverse.com/thing:27322 Eckstruder (mounted on some washers)
- Usual vitamins (bolts, nuts, cable ties, springs)

You think that you will get the hostless printing with Repetier soon? Some days/weeks/monthes? :p Can't wait !

I presume the green plugs are your emergency stop? Nice idea.

 It's actually the wires for the extruder heater - wasn't sure of the ribbon cable would handle the current

And still want to be able to unplug printer from controller/psu to make it easy to transport (doing weekly printer builds at local hackerspace so have to be able to carry my printers around)
