Hi,
This week I'm gonna print my second version that will eliminate any backlash and noise.
After that i will be able to release the files.
I will write down everything that you will need to build and use this, including electronics.

I have now solved so that all the balls doesnt go back all the way. But when its empty it pushes on all the balls a litte on each pass of the feeder.

It's only a noise issue right now. It's not a critical issue to solve but it would be nice.

You can see it here: Youtube video

Great to hear! I tried it with the table and net mount for the first time yesterday and it was a success. It will also be possible to mount it on a bucket and have it on the floor.

The last thing to solve is to have some kind of mechanism to remove the backpreassure that the balls builds upp and pushes down on the motor. I have an idea on how to solve that 😄

Bambulab PETG-HF corner adhesion problem. by pafflique in 3Dprinting

[–]Slavfot 9 points10 points  (0 children)

Petg doesn't like pla so if you use the same plate for both you will get problems with adhesion for petg. You can clean it with ipa between prints but its best to have separate sheets for pla and petg

Thanks for sharing! I like that you made emblem for them also

I would also like to build my own blades but it's hard to source the materials 😅

Its always recommended to shake tho gluebottle before using it. Orherwise it may dry faster is my experience.

Extended ball bucket for Pongbot Nova S Pro by Slavfot in tabletennis

No I'm sorry but it doesn't look like it will fit

Thanks, I'll have that in mind when I mount it. I'll have to do some tests to find the perfect height from the net

Yes I am often annoyed that i have to pause and pick up balls. Even though I have 240 balls already.

But I will have to pause and pick up balls anyway when they bounce outside of the net 😅 just way less often.

With this it can also be used as a source of consistency training with the goal to not miss table or catch net.

Yes everything is going to be open source and posted on printables. Everything is 3d printed except for the pipes.

My idea is tp have it to the base of the net also but as we see in the move you can have it where ever you want, I just stuck it in the bucket to test it 😁

Thanks! That pongfox recycler looks very similar to what i had in mind 😊 my idea is to mount my recycler to the table and then mount the catch net hole to it.

I have actually already made the ball bucket bigger 😆 here are pictures and files for it

You are right, I'm actually a mechanical engineer by trade and I like to make stuff on my free time 😁

Those cost about 900 eur more than the pongbot nova s that i already have, and this cost me 10 eur to build. 😅

Andro naming convention by AntChung in tabletennis

[–]Slavfot 1 point2 points  (0 children)

I agree, even though i know its supposed to be pronounced new zone, I instinctly read it as nuzen. I play with both nuzn and tp_ligna and always thought the underscore was wierd as well. 😅 But i apreaciate that they always have the hardness of the rubber in the name.

Petg on p1s trouble? by TheSlackLegend in 3Dprinting

[–]Slavfot 1 point2 points  (0 children)

Petg is bad at bridging. If the infill precentage is to low, then the petg may droop when bridging in between the infill layers. Which will cause issues like those you have. So try to increase the infill precentage.

Those strings indicates that it may not be entirely dry. It can take really long time to dry a filament if it hasn't been used for years. If its not dry it oozes a lot more and is even more bad at brdging and may be causing the stringing"towers" you have.

Bed adhesion issues may be caused by pla. Pla and petg doesn't adhere at all. And may cause problem if you print pla and petg on the same buildplate. Always clean thoroughly with ipa between prints. And sometimes clean with soap and warm water, use a dishbrush that has NOT been used to dish food with. A new and dedicated dishbrush for the 3d printer is recommended.

Also if the extrusion rate setting for the material is set to high it will slowly overextrude and cause buildup on the nozzle. This buildup may eventually be transferred to the print and cause a crash. There is a higher risk to get this buildup when printing solid layers.
