General 3D Printing Talk / PrintBL Sapphire PLA... no worky... suggestions?
« on: February 08, 2014, 08:36:48 PM »
Hi guys,
I've had my duo for a few months.  I've been running ultimachine black ABS, natural HIPS,  and a gray PLA sample they sent me without issue.  I've also been using the yellow and red/orange samples that came with the bukobot.  Are they diamond age from printbl? 

Last week I received a 1kg roll of sapphire PLA from PrintBL.  I've made around 20 attempted prints.  Only one has completed correctly (an iphone case).
I'm getting excessive extruder clicking/skipping to the point that it isn't putting out much at all, but it only happens on thinner walls. 
I've tried temps from 170 to 210.  I've also tried slowing down the print speed.
I've switched to the second extruder hoping that would help.
I've disassembled the extruder and tried to free it up a little (assuming too much drag).
I've increased the voltage to 13.8 with the trim pot on the power supply.  I have not tried reducing it below 12.
I've removed material from the plastic piece the locking lever rests against to reduce the pinching force on the filament.

My other 3 pla filaments work fine.  Any suggestions would be greatly appreciated.

Thanks,
Michael

General Assembly Talk / Two different heaters?
« on: January 22, 2014, 07:42:27 PM »
I'm having a ball printing stuff, but I have a question.  Extruder 1 heats up way faster than extruder 2.  I pulled the heater elements out of the  blocks and the slow one says 24V.  The faster one says nothing.  Is this normal?

Thanks,
Michael

General Assembly Talk / What am I going to do wrong? New Duo!
« on: December 27, 2013, 06:50:58 PM »
My Bukobot Duo kit (first 3D printer) should be arriving today.  What common problem/issues do I need to look out for?  Do you guys have any tips & tricks that will help me through the building process?

Thanks a bunch,
Michael

General 3D Printing Talk / talk me in to a Bukobot Duo
« on: November 23, 2013, 04:55:05 PM »
I think I want a Duo instead of a Replicator 2X.  Am I crazy?

I'm an optician and an RC aircraft designer/modeler, and I'm going to be purchasing my first 3D printer soon.
I could really use some insight from the experts.

What I'm searching for:
6.25"X7"X5" minimum build area... I will be printing eyewear frames among other things.
Dual extruders, or ability to upgrade to dual without reinventing the wheel.
Ability to print ABS... I'd like to be able to print PVA and nylon as well.
Accuracy and finished surfaces are a priority... I'm not too worried about speed.
I won't mind assembling it at all, but I will need a full kit. I don't want to be sourcing all the parts.
I won't mind fiddling with it to dial it in, but I'd prefer not to spend three or four hours a day on it once it's up and running.


I've been reading everything I can get my hands on, but I could sure use some first hand knowledge!

Thanks in advance,
Michael
