QuotePDBeal I've had very good results with Hatchbox PLA or eSun PLA and eSun PLA+. Both have been very easy to work with and relatively inexpensive ($20-25 depending on color and availability) from Amazon.com. However, I once saw a "cheap PLA" advertisement from Deltrprinter, and bought a few rolls. I've had nothing but trouble getting them to extrude properly. I've ended up getting them toby dlc60 - Reprappers
It has become increasingly clear to me that not all PLA is created equal. I have PLA in red, green, blue and yellow. They are all from different manufacturers and seem to have different characteristics. I will experiment with what I have and see how it works, but there are hundreds of options out there, what have you all found is best for certain things? I have been getting 1kg spools of PLA thaby dlc60 - Reprappers
I will add that to my notes and best practices "tips to future self". Every new hurdle leads to more knowledge, right? thanks, DLCby dlc60 - Reprappers
All caused by my wiring harness pulling on the heater block and causing it to rotate unscrewed, just a little. But more than enough to cause total print collapse! I'll watch more carefully for this in the future... DLCby dlc60 - Reprappers
The whole problem was caused by my wire harness pulling on the heater block which caused it to unscrew a few degrees. This caused PLA to leak out the top of the heater block, burn and dribble down on the print job. How is that for weird? It is definitely a mechanical design flaw when there is no way to lock the heater block to the filament feeder tube. I have more carefully re-routed my wirinby dlc60 - Reprappers
Mystery solved. This mess was caused, through an innocent series of events that I didn't connect until now. A couple of days ago my spool jammed during an unattended print job and the filament extruder snapped the filament. To get it out of the Bowden tube I needed to pull the tube from the extruder box. It didn't want to come out and during that process I yanked a bit on the tube. Since theby dlc60 - Delta Machines
There is a subtle bit of tuning that made a LOT of difference to my calibration geometry. The DELTA_SMOOTH_ROD_OFFSET is important here. You won't get everything to work well unless the distance from the center of your build plate (where the nozzle is placed when you are at X=0 and Y=0) to the leading edge of the V-groove your carriage wheels run in, are all exactly the same. That measurement wby dlc60 - Delta Machines
This is the second of my Kossel delta printer questions. My configuration: Folger Tech Kossel 2020 kit build running Marlin firmware from the factory (C)2011. My slicer/printer software is Simplify 3D running on a Win 7 computer. Until yesterday, my delta printer was "dialed in" and printing whatever I threw at it. My bed is flat, auto-leveling was working like a charm. I have a part fan that isby dlc60 - Reprappers
I have two problems, so I will break my questions into two posts. First, my printer and current settings: Folger Tech Kossel 2020 kit build ((C) 2011 Marlin firmware from factory) Simplify 3D slicer/printer software Until yesterday, my delta printer was "dialed in" and printing whatever I threw at it.

I finally got my Folger Tech Kossel 2020 delta printer tweaked in. bed flat, zero offset z probe, auto leveling working right, cal cube nearly perfect, lots of prints, including some that use about 75% of the bed working fine, part fan added. Bliss. And then BANG! Overnight, everything went south. It now does not reach the bed, first layer isn't properly "sqashed", subsequent layers look likeby dlc60 - Delta Machines
I just finished building it a couple of weeks ago from a kit. Folger Tech does not update their firmware it seems. I will look into updating firmware though since I do not have easily adjustable endstops! It seems that every time I get something dialed in I tear it apart and start over.

I have a Folger Tech Kossel 2020 that I have gotten the bed quite flat through code tweaking and such. I'd love to find a way to not have to use G29 to level before each print and tried to use the Escher 3D bed leveling wizard. However, I don't know what to put in for some values. The Marlin firmware that Folger Tech sends out with their printer is 6 years old and does not implement M666 and thby dlc60 - Delta Machines
More conversations with a delta printer noob. Well, the initial success was, typically, beginners luck. After that first run using the little bit of PLA Folger Tech sent, I tried two other brands of PLA and neither of them "stuck" the first layer outer line. The PLA either didn't come out, or curled up around the tip. I have been reading tons of "help me" posts and responses and fiddling witby dlc60 - Delta Machines
After building for about 3 weeks and spending about 3 hours configuring CURA2 to my Folgertech 2020 delta printer I tried a print, using the little 2 meters or so yellow PLA they sent with it. I got an X,Y,Z calibration cube from Thingaverse and printed it. IT PRINTED!!! First try! The bed leveling worked. My cut-in-half, spliced back together Bowden tube worked. CURA 2.4.1 worked.

Quotethosmos QuoteCareless So what is the general consensus on this Folger Tech 2020 Kit in its newest iteration with all the cool ALU parts? Does it remain as one of the better Kossel un-assembled pre-packaged kits that comes with (almost) everything required? I am thinking of purchasing. Definitely want a Kossel, and this one looks reasonably priced considering shipping and base price. Letsby dlc60 - Delta Machines
Hey all, I am building a Folgertech Kossel 2020 delta printer. I have the electronics and mechanics working. I got their older marlin code to compile by fixing bugs that don't work with the new Arduino compilers as well. I have gotten the bed height, Z probe offset, etc. all working as usual. Then I got to the calibration section of their manual that sets the Y_PROBE_OFFSET_FROM_EXTRUDER valby dlc60 - Firmware - mainstream and related support
Hmm. That does not surprise me. Once someone hacks their specific setups into code they are reluctant to change. I think that I'll do the changes and see how it works. There is a "double #define, which is just dumb since they are about 10 lines apart, a _really_ rookie #define with an "=" in it and finally a poorly quoted string literal. Pretty easy fixes those are. Then I'll move the confiby dlc60 - Firmware - mainstream and related support
Eight months after the first posting of this problem, no one has fixed it officially. Bummer. Obviously I have this problem or I would not have posted. :-) I got my copy of the Marlin sketch from FolgerTech when I got my Kossel 2020 Rev B kit from them. I am using Arduino 1.8.2 on a Win 7 system. Getting the exact same errors. I have a couple of questions for those that have applied the fixby dlc60 - Firmware - mainstream and related support
