Itty Bitty Double Extruder

Alright, am I going to have to buy a set of hardware just to find out what the lagniappe is?

wow it came with Spare parts just for me
yo C42 did you get my pm and the 2 hairsprays
man it's working good for both ABS and PLA only thing is first layer bed temp needs to be a bit hot on PLA but that's not going to hurt anything.

Just got your PM. I continue to be frustrated by the notifications from this site and wish for tapatalk support.

Thoughts on infill for these parts? Would 15% be pushing my luck?

**TechMasterJoe** · 01-08-2015, 03:33 PM

15% might be a tad low but 20% will work fine also depends on the type of infill
i print the Nema 17 ver at 15% and 3 prem with 5 top and bottom and it's really strong but looks like turds
try to fix my extruder flow and z problems before i print C42's nema 14 org

I print them at 40%. I print everything at 40%. Come to think of it, I never think about it.

I printed them all at 15% and have had no problems. The only thing I printed higher was the idlers because the are under a lot of force. I printed them at 50% infill.

C42, thanks for the hardware kit. Very fast shipping and a "gift" in mine as well. I'm new to the 3d printing community so I'll try not to newb it up. With a name like mine you'd expect me to have a handle on these kinds of things. All of my parts are in the process of arriving. Looking forward to joining the IBDE crowd. And it goes without saying, but thanks for the design as well.

Couldn't find the answer to this anywhere:

When wiring up the second extruder, I get that we use E1 for the motor and D9 for the heater. I'm assuming I use T2 for the thermistor? Is there anything else I need to do in the firmware to associate the two?

Also, does the LCD display temps for both hotends?

**RobH2** · 01-10-2015, 03:06 PM

Yes, the display shows both temps however mine is reversed and I can't figure out why. The right-hand temperature readout is of the left-hand hot end.

Here's a hookup guide I made from some other ones.
