@Darrell - that's a very fine print of the pink panther woman, and the owl is sharp too, nice job. @BenitoSanduchi - Nice vase, I have just been printing your fine plus vase model, really like it and quite a challenging print when done small and Hollow.

@Plexus - Very nice setup and print, what temperature are you running the ABS? have you tried a little lower, it may help get rid of the wisps. @richgain - Great print, is it doing much retraction on that model? I would be interested in what setting you are using for 'Minimum travel after retraction' - Slic3r Extruder settings. - I'm using Z list on all my printers for every print now, I have yeby richrap - Competitions

Wow! this is getting Awesome, very nice prints everyone. @Petrus - Very nice hand, your 0.05mm layers are doing a great job - what printer and setup are you using? The Owl is also great, I did a similar print today, but it's not a good as yours - (only 0.15mm layers, I'll have to retry lower) And I'll have to try the Octopus he looks really fantastic. @Sublime - Very nice indeed! - that iby richrap - Competitions
Re: Best Belt-Less RepRap and Printer Designs (Rack & Pinion Rostock 
) - 11 years ago
Don't overlook the use of Spectra fishing line, it's working well on Tantillus and Rostock based machines. It's easy to tension and seems to stay very tight, I only have about 80 hours printing on Tantillus but they still ping without having any further adjustment from initial setup. I can't imaging belts working as well for small machines like Tantillus. I have stretched and damaged enough beltby richrap - General

Re: J Hotend @ $49.50 in stock !! - 11 years ago
Yes, we have had some very bad experiences with recent J-head clones, people are not going to waste their time on a design unless you have some members in the community actually saying it works, how well and what the issues are. (Every hot-end has issues, it's better to be up-front and state them) And since you are leading with the price, that does not look like a good start for most of us. If iby richrap - For Sale

Awesome!, I would love a lasercutter, but like you can't think of any real reasons to actually have one, I could make do with a DIY CNC really, and again don't really need that either.

Great start Petrus and Gulf, they are wonderful prints! thanks for kicking this competition off with style.

Re: Bed material for nylon printing - 11 years ago
I'm Printing with Taulman 618 (1.75mm) on a Tantillus, no heated bed, just blue 3M tape - I was wondering if anyone else has started to reduce the print temperature? I started at 240 (calibrated with a thermocouple) and have lowered down to 200 degrees, the parts seem as strong as the higher temp prints, so I don't think Nylon needs such high temperatures people seem to be using.

Re: Taulman nylon - 11 years ago
Taulman 618 Nylon first print on Tantillus - Even with a very thick wall (this is 4 perimeters and about 1.8mm thick) it squashes and feels very strong indeed. Layer bonding is stunning even at lower temperatures ~220 degrees C It feels like you could hit the parts with a hammer and they would just bounce it off. - Maybe I'll try thatby richrap - Tantillus
Re: New Slic3r - 11 years ago
Hi Brad, Yes, Tantillus is great, really love it. I have made some changes to allow the use of 50mm long NEMA17 motors, 1.75mm filament (Extruder and carriage mods) and a few other tweaks. Are you or do you plan to collect user's mods and changes to parts anywhere on Tantillus.org?

I'm printing with Taulman 618 Nylon on Tantillus, it doing really well with the first few prints I have tried. I'm printing in exactly the same way as PLA - onto Blue 3M tape, I am getting a little lift with things about 40mm+ wide in size so other tapes could do better. Makealot suggested using Tufnol as the ideal print surface for Nylon, I'm waiting for some to arrive to try that out. I haveby richrap - Tantillus

Re: Make this forum and RepRap.org faster, You can help! - 11 years ago
So many of the posts on this forum come from people picking up things found on other communities and site feeds, so it works both ways. I see community interaction in the same way as 3D printer development, it's survival of the fittest for both the designs and methods of discussing, sharing and archiving.

Re: Best extruder and hotends out there - 11 years ago
Direct drive means the filament is driven by a Hobbed drive wheel fitted to the motor shaft. Geared extruders usually have a small gear on the motor shaft driving a bigger gear, that big gear drives a Hobbed bolt that moves the filament down to the hot end. Geared extruders usually give more steps per revolution so you can get very accurate drive and higher torque than a direct drive. I alwaysby richrap - General
