Don't have a davinci anymore, but it should work on any open source printer. I used the same temps as I use for ABS (240/110) but didn't do much testing, so I'm sure it could be optimized. I also only tried with ABS.
I'm excited about DOW's new universal support material (says it works with ABS/PLA/PETG/TPU) although it is a bit expensive (https://taulman3d.com/buy-direct.html) Anyone try it yet

I figured out something that I think is worth sharing. As stealthtransam said, the RRD fan extender only uses pins 6 and 11. The current Marlin actually uses 4 and 5 as the default with the fan extender physically shifted up two pins to align with those two pins. This means the two servos (6 and 11) are still available.
To use 4 fans we should be able to just use a second fan extender board with

I want to follow up with this. The support material from stratasys (SR-30, ) may cost an arm and a leg, but it's totally usable in most 1.75 mm extruders. They use 0.05" filament diameter (1.27mm) so it's a good deal smaller, but it worked in my Davinci 2.0 with NO MODIFICATION! It's $400/80 in^3 (~1.3kg) but it works and I've found plain water will dissolve it slightly enough to get it loose, al

@mikh3x4 have you figured out the answer? This is an old post, but I've carefully read all 6 pages and while there are lots of great improvements and insight, I feel like there's no comprehensive solution.
To sum up what we've learned: Slic3r incorrectly approximated the profile for EW<=nozzle diameter, but I personally think this was not far off enough to cause issues on the order of what m

I've had this issue since switching to 1.2.9. I've adopted each incremental update and seen some nice changes, but with this version I've had some crappy prints (hit or miss).
It seemed to be dependent on the wall width but I couldn't figure out exactly why. It looks like when it's just the right width, the infill is considered "gap" infill and the gap calculation causes overextrusion?
It's prese

Does the "smart ramps" have a due-compatible firmware with support for this board (408) yet?
Can I just add this to bobc's firmware? I just got my smart ramps, I'll try it when I get a chance.
I see the SD card should work, does the standard LCD/SD card reader combo work? (I'll solder the aux-4 header pins)
Also the same question for the rrd fan extender?

in windows 8 you have to get into a mode that allows for the unsigned serial driver to be installed. (detailed here )
With this driver installed, your pc should be able to recognize the board upload. not sure if you still have to use arduino 0022, thatll be nice when we dont have to.

I'm working with a printer with a 12 tooth gt2 (2mm) pulley and I'm doing the ustep/mm calcs.
Isn't the fact that the teeth are a multiple of 3 a problem?
My calibration values are: 400steps*32usteps/12teeth/2mm(per tooth) = 533.333... usteps/mm
This means it's 533 and 1/3 usteps/mm or 16.666... full steps, wont we lose those decimals eventually leading to error?
My logic behind this is the pro

I'd definitely like to try this. I have a ramps-fd v1 and cant find a v2. Having trouble with the bobc's marlin for due and repetier (which both supposedly support ramps-fd).
Any luck on this? I'd think it'd only be 60-70 usd

Alright, this is going to be a lot of info, but I've had a difficult time finding out where to start with due+ramps-fd. I found the Due for cheap from banggood (http://www.banggood.com/Arduino-Compatible-DUE-R3-32-Bit-ARM-With-USB-Cable-p-906466.html, $20) and RAMPS-FD from Geeetech (http://www.geeetech.com/new-pololu-shield-rampsfd-for-arduino-due-3d-printer-controller-p-770.html, $28).

All my searching had let to this. This is the ultimate solution. PVA sucks, we have to come to with something else. I have a HYREL "engine " that can do 4 extruders no problem, but there's boo reasonablw super material out there.
My dept just got a mojo and I saw this material (looks like already in 1.75 mm filament). I'll try it and report back. It's super expensive, I want to say like 300/kg b

I've done a ton of printing and was relatively new to PLA until recently.
I just could not for the life of me get the edges of the robohand parts to stop curling (https://www.thingiverse.com/thing:44150)
I tried double fans, higher temp, faster perimeters, lower multiplier, nothing worked with slight tweaking to these parameters
I had to increased the temp to 205! (for PLA I didn't think it sho
