Geared Mechanical Box V2

Ce n'est pas impossible, je l'ai imprimé moi-même plusieurs fois. Vous avez besoin d'une bonne première couche. Cela peut aider à augmenter la température de la buse et du lit d’impression. Assurez-vous également que le lit d'impression est propre. L'utilisation de colle pour lit d'impression aide également

il faut que j'augmente la température de la première couche?
j'ai mis de la colle sur le plateau mais à chaque fois arrivé à 90% d'achèvement les pièces commence à bouger.
Ca ne serais pas mieux de les imprimer une par une?

Avez-vous activé les "brims" pour la première couche ?
Oui, augmentez la température de la première couche et si possible diminuez le décalage z par rapport au lit d'impression pour obtenir une liaison plus forte avec le lit d'impression.

les brims?

brims c'est un réglage slicer, je ne sais pas comment ça s'appelle en français. J'utilise actuellement le traducteur

je voudrais bien vous partager la photo mais je n'arrive pas

problème résolu changement de slicer

Vous pouvez m'envoyer la photo sur Instagram pour que je puisse évaluer quel est le problème

Looking at evereything you tried, I think that you might have the flow rate or nozzle temperature set too high, which result in slightly too much extruded material the nozzle collides with during travel. Also the fact, that you have bad quality, when printing a single gear makes it look like, you have unsufficienf part cooling, which can be a result of too high nozzle temp or weak cooling fan. I suggest, that you lower nozzle temp by 10°C, lower print speed, enable Z-hop during travel and lower flow rate by a few percent in the slicer. Also increase the print bed and nozzle temperature during the very first layer to make a stronger bond of the filament and the bed. The last thing which could help is to decrease Z-offset of the first layer, to increase the pressure the filament gets pusched on the printbed.

Make sure that the first layer is clean and the doors do not have an elephant foot, which happens when the first layer bes temperature is set too high, or the Z-offset is too small. If you are not familiar with the term elephant foot, you can find a lot of information about it on the internet. The second thing you can try if you are sure that your first layer is fine, is to decrease flow rate, because if the doors do not fit, it means that the dimensional accuracy is not good and too much material got extruded.
The last thing would be to slightly downscale the door gears by a very little amount. You could print them one by one with different scaling factors to find the best.

Thank you very much, I really appreciate it!

Thank you very much for the positive , I am glad that yours turned out so well. Applying some lubricant is key to get a smooth mechanism. I intentionally made the tolerances a little more tight to make a stiff and non wobbely mechanism ;-)

Use brims and make sure, that you have a clean print bed, you should clean it with isopropanol from time to time.
Also have you tried applying adheasive spray or glue stick to the print bed?
I also printed them on P1S without any failures, printing at 0.2mm layer height and slightly decreased print speed: 60mm/s outer wall and 120mm/s inner wall speed.

Tried without brims, though it can affect the gears. I will try with, sure it will be easier.
Thanks for the quick response.

It won't affect the gears, I made them conical at the bottom, so the first layers of the gears do not have to be that clean.

Unfortunately the roads keep falling at the end of the print, even tried with and one road only.

Try decreasing Z-offset of the first layer, so that the first layer gets a stronger bond with the print bed.
Also maybe you have slight overextrusions, which result in imperfections, that the nozzle collides with. (you could try decreasing flow rate)
Hard to tell honestly, just by reading your comments.

Use a brim and manually add a small tree about half way up on the smooth side. The tiny imperfection left when you snap off the tree is super easy to clean up, but will give plenty of and stop all the falling down.

On my P1S with high quality settings, meaning 0,2mm layer height and moderate printing speed, it took about 24h to print everything

The deck insert's dimensions are 65x90mm. If this is not big enough, clould you tell me the dimensions of sleeved mtg cards, then I could adjust the dimensions if necessary?

Just printed one last night and no they are not big enough for sleeves. Not even a mm is needed to make it big enough. Also the card/dice insert will not fit a full deck of magic cards. The insert could be modified to removed the dice tray and make the insert for just cards and I think that will make it big enough to fit a whole playing deck. It would be nice if the 7 tray dice insert and the card insert could both fit in this device. Do you think if I scaled everything vertically the device would still work as intended?

A MTG sleeved card is 66mm x 92mm

Thank you for the dimensions, I will adjust the deck insert accordingly.
Upscaling everything vertically could work, but it would be better to increase the z-height of the box and gear rods in order fit the deck insert and the dice tray.
I already did this and am currently printing a prototype, I will soon get back to you.

Wow you are amazing!

So 65x66x92 would be enough to fit an entire MTG 100 card commander deck.

It is shown at 01:00 in the youtube video

My apologies, not sure how I missed that. Very excited about this file, printing the gears right now!

You are welcome, I forgot to lay the part on the desk at the beginning of the video, maybe thats why ;-)
Happy you like my design!

After dropping the gear rods in I can rotate in one direction relatively without friction but it will not turn the other direction. Any advice?

Did you apply some kind of lubrication (silicon oil for example) to the surfaces of the moving parts? As mentioned in the assembly guide, this can be helpful with some filaments and depending on the print quality.

I thought that was only applicable to silk. I used pla+, I will try some silicon lubricant and let you know. Thanks!

I am sure that it will help a lot. I would also lubricate the upper gear of the gear rod (where it gets in with the box). You mentioned, that you only get friction in one way, this could indicate, that the friction comes from there, because of the helical gears of the gear rods, the rods create a downwards force in one turning direction and an upwards force in the other direction.
Maybe the friction is too high, when the gear rods create that downwards force.
You can also check out the assembly video of the lately released box, there I show the lubrication of the gear rods more precisely:

https://youtu.be/C3YM8uqFHmI?si=0g_Ry87gLcCX2ePe

You were 10000% correct on the lubrication. It glides so smoothly, very impressed so far. I'm definitely going to be buying more files from you!

Yes I think it should be possible, I did not try it myself though. The only thing I am not sure about, is if the bottom and top sungear still snap fit easily on the box. If you want to be sure you could start by printing the bottom sungear at 120% and then when finished the upscaled box, but just the bottom section by stopping it after 10-20% print time to see if the sungear still can be connected with the box without problems.
I hope this is helpful.
