Itty Bitty Double Extruder

[RobH2]

I've modified the stepper center holes and elongated them. Let me know if you think this is enough.

Anyone have the config files for the ittyBitty with ABL for the i3 8" we are having problems getting the ABL setup.
Thanks

OK after spending the day with settings and some Budweiser we have everything working except we have an x and y shift between nozzles. Can anyone shed some light on where the nozzles shift setting are?

Sorry I didn't reply earlier. You can see my config file here:

Click the "RAW" button to just download the file. You will need to adjust the Z probe offsets for your particular setup.

You have two options. I think RobH set his up with the offset in the Marlin firmware. I did mine in Slic3r. I just set the offsets to [10,0] and [-10,0]. This was close enough for me because I spent some time adjusting the tension of the center screws in the groove mount to get them exactly 20mm apart. If your unit isn't aligned perfectly, you can adjust the offsets to compensate.

Thanks for the reply. I found the off sets in my slice software and also in config_h.

Well i have been trying to print this for the last 2 days nothing has worked to hold ABS down
i can print all day in play and it comes out flawless using hairspray but in ABS the stuff just pops off the bed after about 30 layers and not just this any thing i print in ABS seams to do this
can i get links to other known good ABS filaments and maybe some known good slic3r ABS settings

i tried low in fill 10% + 3 shells(and more) , tried cura 14.09
i can't even get 5mm tall 10x10 calibration cubes to stick to tune abs flow
even a raft falls off the bed

room temp 76deg F dead air no fans

things tried
hairspray
glue stick
abs slurry
kepton tape
even frog tape

i print with abs all day at school and never have problems like this so i think it's this cheep eSun (prototype supply) ABS
the PLa i get from prints better then any PLA i have used but I'm starting to think they suck at ABS

added note if anyone needs belts i ordered mine off aliexpress i have them now in hand i have 52 of them left (my 1/8 on-road R/C uses them to lol )
i have 30 of the 188mm used on the single extruder ver of this as well

How often do you clean your glass plate? Try cleaning it with acetone then alcohol, then putting your adhesive on the glass. I use glue stick, and put it on when the glass is cold. I then use a brim of 4-5mm (not a raft), and rarely get any warping anymore.
