Printrbot XL Mod
by Datenkrieger, published
Plus some changed details.
New build platform is now over 30 x 30 cm, and still printing nice. I have not testet all the limits yet, must add some feet to the base or it will tip over with big prints.
Experiences so far: It's louder than before, can't leave it printing during the night or my neighbours will kill me... it's building up more vibrations, also sortof a y-wobble. Most of this is probably because of lm8uu bearings with missing balls but the whole construction needs to be stiffened. If I had more space I would build a massive wooden frame around it.
Replaced the Base with Japica 608 Base, runs much smoother now

thanks a lot :-)
I now have a 8x12 bed and about 15 z axis built capacity
I just have a problem with my really powering the heat bed clicking all the time any idea how to modify the firmware to get the printrboard to just send on or off command to the relay ?
ok i had a look at the sources and you need to change the values in configuration.h, scroll down until you see "software endstops"
oh and use the arduino environment for printrboard that you can download at printrbot.com. It is already configured for the printrboard and you can just unzip and start it, no need to install. If you have an old printrboard and can't upload with the IDE, you need to get the compiled file from the temp dir and upload it with Atmel FLIP.

The Y belt is now in the middle of the build platform like thingiverse.com/thing:28423
For less Z-wobble I used the base pieces with Z motor support from thingiverse.com/thing:28557. Not used a Z - top joiner thing yet but it works fine without.
After adding some feet it will be more stable, but smaller prints turned out good. Only headache causing are the lm8uu bearings, I lost some BBs when changing the smooth rods. I will definitely try out the Japica 608 bearing thing at some point.
Warning, Printrboard firmware has software endstops in it, I can't use the whole build surface until i manage to flash a firmware that has it fixed.
fixed the firmware, was a bit tricky because of dfu bootloader (REV.B Board), but could compile it with the printrboard - arduino environment that can be downloaded at printrbot.com support. Then uploaded it with Atmel FLIP.
It wouldn't work at first because i used the wrong sources. Be sure to use the official printrboard sources from github.com/PxT/Marlin/tree/master/Marlin
Added the Z-Rod double stabiliser thingiverse.com/thing:36022
