@warbunniex I don't know if the question is for me, but for Zatsit, it's not an IGUS product, but simply slides machined from Delrin.by M_Xeno - Delta Machines
About guiding solutions: For Zatsit, I used simple Delrin slides, gliding directly on MakerSlide profiles. I don't consider it to be a low-end solution, on the contrary: The ultra-light Delrin slides practically do not contribute to the increase in moving masses. If carefully designed, used in a consistent mechanical architecture, and well tuned, they offer optimal performance for lightly loadeby M_Xeno - Delta Machines
@pkm Thanks for correcting the link ! Of course, such a speed does not concern real life. I wanted to show that Zatsit's technology, its architecture, and the extreme lightness of its water-cooled hot-end, could improve the ratio between print quality and the speed at which it is achieved. I consider this quality/speed ratio to be the true quality measure of a 3D printer.by M_Xeno - Delta Machines

Bonjour à tous ! Voici une petite vidéo destinée à attirer l'attention, avant le démarrage KS : (lien corrigé le 06-09 10:38) Ça devrait vous plaire... Si ceux à qui ça plaît particulièrement veulent bien relayer partout où ils peuvent, ce serait bien pour la campagne. Merci d'avance !by M_Xeno - RepRap Groupe d'Utilisateurs Francophone
L'eau n'est pas un problème pour le transport. Il y a un flacon porte-pompe de 200ml, dont le couvercle est fixé à la machine, mais dont le corps se dévisse. On dévisse le flacon, on jette l'eau, et on peut alors transporter la machine à sec. Je l'ai fait des dizaines de fois.by M_Xeno - RepRap Groupe d'Utilisateurs Francophone
Jetez un coup d'oeil à la HotEnd refroidie par eau de Zatsit, qui va vous étonner. Je veux bien parier ! www.zatsit.fr Le post iciby M_Xeno - RepRap Groupe d'Utilisateurs Francophone
If you buy a 3D printer with the initial price as the main criterion, and then you really use it, there is a very good chance that you want to replace this or that critical component, to have better performance. Your low initial price will mean nothing anymore. And by the time you get there, you'll probably already have spent more on filament than the machine was originally worth. In my opinionby M_Xeno - General
@rialevent La durée de vie des charnières est discutée sur le site www.zatsit.fr, en détail. L'expérimentation a été faite sur 14 millions de pliages. Et un prototype a plus de deux ans de fonctionnement, et a vu passer des dizaines de kilos de plastique. Les charnières sont comme au premier jour.by M_Xeno - RepRap Groupe d'Utilisateurs Francophone
@nebbian You express very well the accuracy requirements for a delta mechanic. It is for these reasons that I propose Zatsit, a delta robot whose joints are replaced by hinges, which are all defined at once by a CNC, which engraves them in a special aluminium/polypropylene composite, with a typical accuracy of 1/50 mm. This procedure ensures a very exact geometry, without any particular effortby M_Xeno - Delta Machines
Il y aura des niveaux étalés de contribution, avec différentes contreparties. Par exemple, on pourra ne contribuer à 25€ pour un porte-extrudeur à la Cardan, ou à 40€ pour un système de Hot-End à Eau, etc... Le kit complet, tel que décrit sur le site www.zatsit.fr, sera proposé à 300€, ou à 250€ pour les 50 "Early Birds" qui s'engageront les premiers.

Bonjour à tous ! J'ai présenté ici, il y a deux ans, un concept de machine delta à réaliser sans mécanique, avec des charnières en polypropylène à la place des joints, nommé ZATSIT. Le projet est maintenant mûr, optimisé, largement testé sous toutes les coutures, et amélioré, notamment par l'introduction d'une hot-end ultra-légère, à refroidissement par eau.

Hi, everyone! I just published information about my new 3D printheads for Zatsit, integrating hot-end, cooling, and double hobbed gear extrusion, with remote stepper motor. The latest model produced weighs only 29g, including support, for all these functions. This work opens the way to a head with four independent materials, but only one remote extrusion motor, which should weigh around 40g...by M_Xeno - General New Machines Topics
Hi Philipp ! Zatsit could be smaller, or bigger, and probably will one day. But first I have to bring this project to fruition, with a bed dimension that is compatible with most of the market. Glad to finally find someone who likes Piazzolla! All I've had so far is comments that the music was atrocious! Piazzolla, atrocious!by M_Xeno - Delta Machines
@Redemptioner Indeed, the wooden braces and the spacer T20x20 are not enough to constitute a complete non-deformable geometry, but they are enough to remove the ringging component that could come from the oscillation of the whole structure. There is virtually no effort involved, just the suppression of a potential vibration, so this simple solution has shown that it is adequate. Hylite withstanby M_Xeno - Delta Machines
Did you know that there is a radically different solution, which escapes most of the problems that affect magnets or rod ends? A system very light, intrinsically accurate and insensitive to wear and tear ? It's Zatsit's living hinge system... (shameless autopromotion) www.zatsit.frby M_Xeno - Delta Machines
@obelisk79 There will soon be a Kickstarter campaign for the Zatsit kit (see www.zatsit.fr), but I don't think I would have time to integrate this extruder, which still requires optimization studies, and especially, for mass production. The association of a POM pinion, and a metal hobbed gear, must be simplified, it is much too complicated to produce in series. But it will be done, because I thiby M_Xeno - General
@o_lampe, shadowphile, VDX Hinges to glue: that's a very good idea! During the KS campaign, I will propose, among the goodies offered to bakers who want to support the project, but do not want to buy a complete kit, hinges ready to glue. For example, a Ø30mm disc, with one hinge along a diameter, and another, with two perpendicular hinges, to make a joint. This would allow Makers to easily iby M_Xeno - Delta Machines

I just weighed, on a previous prototype, not very different from the current one, everything that moves (everything, including carriages, slides, and even belts!), with the Hot-End water-cooled, but without the flystruder setup, the Bowden tube nor the water supply hoses, which are actually carried by the Flystruder support. That's 212 grams, including the printing effector with Hot-End, which weby M_Xeno - Delta Machines
Shameless self-promotion: so use Zatsit's polypropylene hinged system, which is ultra-light, extremely accurate without any adjustment, and performs very well against ringing. Look at the photo I published on this post:by M_Xeno - Delta Machines
The pattern is voluntary, and it is from the STL model, to mark the limit between each speed range. Yes, acceleration was 10000mm/s² that time, so about 1G (1). Usually, I am using 6000mm/s² or so. I tried 3G, no step loss, while extruding with a Flystruder, but extrusion is problematic at this rate. Without any extrusion, and nothing on the effector, the printer supports any acceleration withby M_Xeno - Delta Machines
I plan to launch a Kickstarter campaign for the Zatsit delta kit very soon. The kit includes an ultra-simple and ultra-light water-cooled hot-end adapter that can be purchased separately. It is shown on the photo, with its support, specific to Zatsit, but it can be adapted to any situation. I think it's the lightest Hot-End on the market, and it can, indeed, improve machines with little powerby M_Xeno - Reprappers

@o_lampe Yes, I had to develop, with the company I work with, safe methods to position the plate exactly at the same place recto and verso, and to have a perfect flatness. This manufacturer uses modern machining centres with powerful vacuum clamping, but we also had to design special jigs.

I won't try to change your opinion, but my experience over two years contradicts your assertions: the submersible aquarium pump is incomparably quieter and also much more reliable over time than any DC fan (and I've tried many!). With a drop of hypochlorite in the water, there's no reason to change it. Seeing air cooling as simpler is, IMHO, simply the habit of seeing it everywhere as the standarby M_Xeno - General
@Trakyan I don't quite understand what hassle you' re talking about. I still have air-cooled Hot Ends, which I used at the beginning of the Zatsit project, before I developed the solution with water. I can replace them in a few seconds, if I feel like it, and this will not change any of the printer's other functions (cooling parts, extrusion, etc...). The design of Zatsit is such that all effectoby M_Xeno - General
