Description
Superb design by NOP21, it must have taken many hours of work.
See video of my print working;
Easy to print and assemble. I had some issues with filing the escapement pallet so in the in end I made a few with progressive 0.1 mm removed (in fusion) from the tips (for me a cut of 0.3 mm worked best).
Removing friction appears to be the key to get it to work and also making sure the inner cage is not deformed.
I also found that the power output from the Ali Express springs was variable (at least with the two I bought),perhaps a slightly lower gearing would account for that, although with a shorter run time.
I hope NOP21 will design further excellent clockworks.
Superbe design par NOP21, il a fallu de nombreuses heures de travail.

Facile à imprimer et à assembler. J'ai eu quelques problèmes avec le dépôt de la palette d'échappement donc dans l'extrémité j'ai fait quelques-uns avec progressif 0,1 mm enlevé (en fusion) des pointes (pour moi une coupe de 0,3 mm mieux travaillé).
L'élimination des frottements semble être la clé pour le faire fonctionner et aussi s'assurer que la cage intérieure n'est pas déformée.
J'ai également constaté que la puissance des ressorts Ali Express était variable (au moins avec les deux que j'ai achetés), peut-être un gearing légèrement inférieur expliquerait cela, bien qu'avec un temps d'exécution plus court.
J'espère que NOP21 concevra d'autres excellentes horloges.

Hi Ebolompedo
I have added 3 copies of the escapement pawl, they have been corrected to get the angles specified in NOP21's images and the ends have been reduced by 0.2mm, 0.3mm and 0.4mm as per the file names.
My Gyrotourbillon print runs around 1-2 minutes at best. Once I had sorted out the escapement the Gyrotourbillon did run but only with hand pressure on the gears not by the spring. I eventually managed to get it to run on it's own by sanding ALL the teeth of all gears and checking all moving parts and sanding as required. I also put some dry PFTE lubricant on the gears and pinions etc in order to reduce friction.
I found that the cages affected the friction and needed some slight (hand) pressure to square them up once assembled.
I'm not sure that FDM 3D printed clocks have the dimensional accuracy to reduce friction to give long run times. I spent ages tweaking the Gyrotourbillon to get it to run. I did think about changing the power train gear ratio to produce more torque but did not get around to it. NOP21 has provided the source files so it would be an easy mod to do in Fusion etc.
Hey clock56!
Thank you very much for your fast response.
I will gladly use your model of the escapment to get my Tourbillon running.
1-2 minutes runtime are more than enough for me and i am very glad yours runs so well.
As soon as I fixed my broken extruder I will continue to work on this awesome project.
With a bit of luck mine will run in a week or two.
Well done!
How long dos yours run if you wind it all the way?
And could you maybe upload the .stl for the edited escapment?
