Re: Kossel XL - some autolevel help needed - 8 years ago

Hi, I'm reading a lot of auto leveling and problems with it but as a dummy in this matter could you explain why you need the auto leveling system? I have designed and build 2 Delta printers and will start with my 3rd one soon but found no need for auto leveling until till now. What does is bring else than confusion? (For me) If you have build your printer with straight and perpendicular pillars

Re: Preventing PLA clogging the Hot End request - 8 years ago

De two steppers are 2 Euro steppers 28JYB-48 modified to bipolar. Both on ONE 8825 driver The total weight including effector and hot end is 162 grams. See attached Delta Printer spec I designed in 2014. Of course I needed to deviate from my original spec but it did help me with my final design and for finding my way in this fun project. best regards Ed

Re: Preventing PLA clogging the Hot End request - 8 years ago

Super thanks for the STL file. I will implement this tool immediately, good job. Using release agent is as old as the extrusion techniques exist; I should know after 40 years of experiences, I was curious if other 3D printers are using it too. Oiling for me it's a blessing in my home made super light extruder in my Delta mounted on my Effector. I needed to eliminate as much as possible friction

Preventing PLA clogging the Hot End request - 8 years ago

Dear 3D printers, I have a request to you all but first my little story. I was using PLA for a while until I was fully fed-up with clogging my Hot End no matter what I did. I start using nGen from ColorFabb and I had no problem anymore regarding the clogging but .... it's quite expensive. Reading some blogs about PLA and the clogging problem I found some 3D printer guys talking about oiling t

Re: nGEN PLA from ColorFabb - 8 years ago

Oops, yeah 0.05 mm layer thickness, that's just 0.03 mm over my Delta repetitiveness value, amazing low layer thickness. It wouldn't work for my Delta printer and more for my Hot-End, in fact I never have seen a low layer thickness like that, ... good job.

How to make a sanded surface shiny again? - 8 years ago

After sanding a plastic surface, the surface gets dull and sometime you like to keep the original shiny appearance. Also after cleaning some bubbles on the surface by a sanding operation, the below is a nice fix of the surface. - A sanding paper with a grit of 180 is used for sanding the plastic surface. (Do a few experiments what works for you.) - Take a gas torch and carefully wipe with the to

nGEN PLA from ColorFabb - 8 years ago

I have printed now about 1.5 Kg of the nGEN PLA from ColorFabb and I didn't had one single Hot-End clog. On top of that the shrinkage is very consistent and no warping on big parts. (>120x120 mm) Before randomly my Hot-End was clogging and that is not nice in a 10 or more hours print. The nGEN PLA material is quite expensive but for me worth a lot because I can start a print and don't have to

Sugar water as sticky media for the print - 8 years ago

I'm using now Sugar Water for over a month and after some struggling with this funny solution it works just great, over and over again. My mixture is about 1:1 = 1 part Sugar one part water fully solved during a short warming up. Make sure that is a 100% saturated mixture and fully solved. Apply with a cloth a thin first layer, heat up the bed and apply another thin layer of the sugar water solu

Re: Dimensioning and Tolerancing - 8 years ago

I disagree on the statement that Deltas are not that precise. I have build two Deltas now and the tolerances are phenomenal +/- 0.03 mm easy. Cpk value is >2.5 I do agree that from what I have seen is that not many do build a Delta precise enough causing bad print results. - Poles do need to be 100% rectangular to the bed - Arms (ball to ball) do need to be exact the same - Design need to be s

Re: Delta printing inverted (mirrored) X? - 8 years ago

Hi ncshooter, Allow me to throw in some stuff. Are you using Machinekit (Linuxcnc)? Your .ini setting are off somehow. Do you have your end stops linked in series or separate connected to the specific controller pins? If in series, the first end stop reached will win.

3D Delta Printer D16_EBOT part 4 - 8 years ago

I started my build with milling basically three the same plates. Two bottom plates who are sandwiched with spacers, holding the electronics and stepper motors in between. and a top plate. The three plates have all the same hole pattern for the D=16.00 mm (0.63") silver steel poles. This makes that the hole pattern is super precise and should enable me assembling the parallel arm bearing blocks wi

Re: Replacement of Hairspray or Blue Tape - 8 years ago

I wipe my glass plate with a cloth drained in sugar water. Do not spray! Your spray bottle will get clogged and your sticky spray is all over the place; just use a clothe and gentle wipe the glass plate. Be kind of sweet to your stuff

Re: Replacement of Hairspray or Blue Tape - 8 years ago

Allow me to post my experiences in short cuts: 1) Leveling a surface is not the same as flattening a surface. Often these two things are mixed with frustrating consequences. If a surface is not flat within 0.1 mm, leveling has no use, ... it does not solve the problem. 2) An aluminum bed elongates (becomes bigger in diameter) when heated up. 0.3mm (0.11") for a bed of 230 mm (9") If a heated bed

Replacement of Hairspray or Blue Tape - 8 years ago

Hi, I was struggling like many of you with the adhesion of the plastic to the heated bed. I was okay with PLA on blue tape and an unheated bed but due to the very poor quality of this filament by 123-3D.nl I stepped up a notch and bought nGEN PLA from Clolorfabb. What an amazing quality PLA is this, no nozzle clogging anymore and a smooth silky feeling material. But as many changings in life it

D16_EBOT - Unwind stand - 8 years ago

Using a "reel unwind-stand" for the filament coil or reel to unwind is a great added value to your 3D printer and I will explain you why. A full filament reel or coil has a weight of at least 1 Kg. Most of the reels are just hanging in the core while the extruder is pulling on the filament, unwinding the filament and at the same time pushing the filament trough the hot-end, that's quite something

3D Delta Printer D16_EBOT part 3 - 8 years ago

When starting a new design it's good to describe as precise as possible what you want to achieve. While doing so the design iteration process does start automatically and although you're on your own in your study room or so, you start already a kind of design FMEA. When you're ready with the design specifications you start your design in your favorite CAD System. My system at home is Alibre, it's

3D Delta Printer D16_EBOT part 2 - 8 years ago

So I figured out that not all free picture upload/share websites are for free but "postimage.org" should work, so now I can show you my D16_Ebot printer in this blog. But I see I do need to work on the quality. (Some tips could bring me up to speed here) I will describe the build here and for those who do need the step files, please let me know. The base is a sandwich of two 18mm MDF plates.

Re: slic3r x/y distance control in slic3r - 8 years ago

Thanks for these great practical tips. I did quite some filament measurements lately and it's not that easy talking about an average I believe. For example 30 measurements over 10 meters (33 ft) gives me on a particular reel an average of 1.734 mm but 5 meters further I did get an average of 1.782 mm. When Slic3r set for 1.734, my extruder will experience quite some push back pressure when the f
