Faulty BLtouch: not stowing correctly (read description!)
Issue appeared few days ago, unclear the cause. The pin works fine without any friction and is not bent. I can deploy or stow manually with Klipper and it also works most of the time fine.
It was then replaced under warranty and the issue disappeared. If you see the same, ask for replacement.
UPDATE!
After reading about demagnetisation of neodymium magnets even at temperatures as low as 60 °C, I think th cause could be the hours of printing with the printer enclosed (35 °C) and with the bed at 120 °C, which likely caused the temperature of the magnet inside the BLtouch to raise at 60+ °C and lose strength, therefore failing proper detection.

Flowrate test for nylon on a Printrbot extruder and hotends
Просмотров 193 года назад
I tested nylon to understand the behaviour of my extruder hotend combination and to find out the maximum extrusion rate I can push. The data is not very clear, because, as I found out later, the slippage of the filament is intermittent, probably due to the feed line.
Printrbot to HEVO
Просмотров 353 года назад
The Printrbot used A4982 at 12V as drivers, the HEVO uses TMC2208/TMC2209 at 24V. The vibrations and noise from the stepper motors is almost eliminated during acceleration, and completely eliminated during constant speed motions. This is the first test with the printer, the settings can be improved.

I picked up 2 at goodwill for only $6!! No charger but that's cheap enough, one was the nozzle the other was a pinched line. Good score???
😮😮😮😮😮😮😮😮😮😮😮😮😮😮😊🎉❤❤❤❤❤❤😅😊😮😢🎉😂❤
Spoop-D printing
Titled "Remove and clean" and finished with "it's not spraying uniformly. I guess we will leave it this way"
There no contradiction. I removed it and I cleaned it, but since there was some physical damage maybe because of previous attempts to clean it with a toothpick, it kept spraying poorly. Even if it's clean.
Hello, after disassembling and cleaning everything, I found that the filter was closed.
Which filter? I don't remember any besides the one in the opening for refilling
I took the nozzle (two screws) let it seat on a small plastic cup with vineger (used in salads) for 1 hour, then use a little air pump and flush it, put back in place and works as new.
Good to know, but unfortunately with mine it didn't work. And iRobot doesn't sell the part.
Are you able to list the make and model f your Ultrasonic Cleaner ?
Any in the 30-50 Euro range will work.
Thanks but audio instruction and reassembly are needed.
I took mine a part. I ran vinegar through the tubes. I soaked the nozzle in baking soda and vinegar overnight. Right away I noticed debris floating in the water. Now it works like brand new. Thank you for posting. Don’t tighten the screws too tight that will make them almost impossible to remove for the next time you need to open the casing. This was a helpful video! You saved my braava. Subbed!
do you have to do this regularly? my 240 just started being clogged, haven't taken it apart yet, but I've only had it a month :(
How did you get into the tubes? I disassembled the robot but I could arrive to the tubes, just to the mother board and tank
Did you fill of vinegar from the tank of the robot instead of water?
Check wiring. Fixed a similar problem for me.
The issue was hardware. Changing wiring didn't help, a replacement did. The reason is that I printed few parts with bed at 120°C and enclosed chamber temperature of 45°C, which likely caused the temperature of the Bltouch to increase above 70-80°C and the high temperature demagnetised the neodymium magnet, which is common even starting at 50-60°C. So bltouch and enclosed, hot chamber don't go together.
I have tried about anything to get the nozzle clean. aircompressor syringe with different sullutions and more. At last I bought a small sonic cleaner, and put the nozzle in a small glass with vinegar (ättika 24%) and fill up the cleaner with water outside the glass. Run it for 10 minutes and it sprays like a new nozzle again. (Y)
I think I damaged mine a little while trying to clean it, so it sprays water not as mist but as jet. It's unclogged, at least.
do you have to do this regularly? my 240 just started being clogged, haven't taken it apart yet, but I've only had it a month :(. which sonic cleaner do you have?
Could you tell us what sonic cleaner you bought? Thanks
Thanks, this tip worked for me, too!
My husband just used a can of compressed air, like you clean your computer keyboard with, to unclog mine.

Useless for me at least, I end up creating a new nozzle myself using some plastic epoxy and a a piece of pen tubing.
Can you post a video or pictures? I'm interested in trying but I'm not sure I understand what you mean. What is a pen tubing? And what do you mean with plastic epoxy? I know what epoxy is, I don't understand the overall structure. You can also make a drawing with pen and paper and take a picture of that one, if you have no photos of the actual repair. Thanks!
ma questi sono i famosi video che anni fa avevi condiviso sul forum del fiat panda club italia o sei tornato di nuovo a caponord?
Sono gli stessi, ma non sono più nascosti
@@olafmarzocchi6194 avresti potuto montarli in un unico bel video che raccontasse la storia dall'inizio alla fine, sarebbe stato bello
@@Psycho93 posso provarci, ma non sono esperto e al momento ho altri progetti. Se riesco a inserire una mappa senza troppo lavoro lo faccio
@@olafmarzocchi6194 puoi creare video della mappa con google heart, viene una cosa molto carina, io l'ho fatto in qualche video
@@Psycho93 per esempio? Come si fa?
Finally got mine clear with Spirits of Salt (low-strength hydrochloric acid), a short length of tubing and a syringe to make sure the acid was properly sucked all the way through.
I will add info to the description. In my case the issue is that I used parquet floor cleaner which probably included some wax for shiny results, so acids may not help much. Still, I'll try your solution and also separately hot water.
You can take off the nozzle and put the small blue pipe out through the hole with something to pinch it: it won't "spray" but at least there will be water put in front of the robot. It's better than throwing the whole machine to the garbage. I'll try to put another spray nose (from perfume bottle) - it should work since the pump exert pressure to open the nozzle so it's basically the same mechanism
Any success?
Just to give you update. I have just communicated with iRobot customer representative and told me that my Bravaa Jet robot needs to be replaced. Quote "We do not advise removing the nozzle off the robot since it's the core of the unit." Another quote "based on the robot's behavior at this point the robot will need to be replaced". I told her that my nozzle is clogged and insisted me to replace my robot. Crazy and ridiculous right? Well, I have no choice but to fabricate my own nozzle. I will update you guys. Still waiting for my resin 3D printer.
I missed out this one: "at this point we will advise reaching out with the Singapore support for more information in regards to purchasing a new unit."
I hope that 3D printing (resin or extrusion) will be able to work... the nozzle is a very accurate part. It would be better to find a nozzle from another spray or somethig and to integrate the nozzle unit into the Braava... at least the "spraying" hole is precise.
@@olafmarzocchi6194 For me it's better to replace it with fabricated nozzle that has lesser quality water diffusion than my current nozzle which release droplet amount of water. iRobot customer service recommended to buy new braavajet and that was unjustifiable for that faulty part. I will be happy and contented as long as my 3d printed will release optimal amount of water.
@@joreal71 it may be better, but I'm skeptical that a 3D printed nozzle can be accurate enough to "spray" water: the hole needs to be very small. As alternative, if it doesn't work try printing the nozzle with the hole closed and to open the hole yourself later with a needle. This would probably give you a thinner hole and better spray. Keep me updated, if possible, my 3D printer is offline so I cannot test myself!
I am just starting to model the nozzle. If you are interested to see the progress, check my github: github.com/owey71/braava-nozzle
Mine is clogged and releasing droplets of water only. This replacement parts is nowhere to be found in the internet and most probably I might 3D print this part using resin material. Already sent message to iRobot customer service to inquire where to buy this spare but still no reply. Anyone knows where to buy this spare part?
If you are able to print it please provide a model, I'd like to do it as well!
@@olafmarzocchi6194 Sure. No problem.
@@joreal71 have you been able to print it? works?
I am just starting to model the nozzle. If you are interested to see the progress, check my github: github.com/owey71/braava-nozzle
@@matiasperin3484I'm just starting to model the nozzle. Too busy at work.
Do you clean your the electric toothbrush base in ultrasonic cleaner as well?? I want to but afraid gonna ruin it, is it safe??
For the base I use my old toothbrush and I clean it manually from time to time. However, if it is rinsed properly and completely after each use, it almost never needs cleaning. It is safe to put it under running water, but the ultrasonic may be too strong.
Great, now I have to pee...🤨😤😰😭🥶😓😥😰😨😱😪😴😴😴😴😴😴😴😴😴😴
My Braava is not going in a straight direction anymore, and I believe is the right side wheel rubber that is gone. Any idea how can I replace it. iRobot charges 79 USD. !
It should be simple to find some rubber and stick it to the wheels... I also noticed it gets worn out quickly
Mine is clogged nozzle(a piece of plastic) and advised me to buy new unit.
There is a video you need to order new traction for the wheel and follow the tutorial how to replace it. It’s fairly easy takes about 15 min to an hour. Good luck.
?????????😴😴😴😴
heilà Olaf, ti sei dato anche tu hai video tutorial? bravo! solo che secondo me dovresti descrivere a voce quello che fai, in italiano o in inglese, come preferisci
Psycho93 beh non vi sono video che mostrino questo processo, ho pensato di farlo. Non mi piace però mostrarmi o far sentire la mia voce...
Olaf Marzocchi all'inizio anche io mi vergognavo, poi ho preso confidenza con il mezzo ed ora mi diverto a fare i video
che poi, ripensandoci sei apparso ed hai parlato nei video del viaggio in panda a caponord
questo problema era capitato anche a me al ritorno da bologna, ho risolti rinforzando la contro molla dell'accelleratore
Il gommino si era incastrato TRA la puleggia e il filo... L'unica era toglierlo. In futuro, posso mettere un gommino nuovo o fare senza, oppure stampare in 3D uno pseudo-gommino (ma di nylon). Non penso però si aun grosso problema.
Olaf Marzocchi nel mio caso non era il gommino, tu potresti rimettere il gommino in posizione e fissarlo con una fascetta
Psycho93 buona idea
*Vietnam flashbacks*
Wonderful Day! Thank you for sharing this with us!! I was also there and enjoyed it a lot. Is it possible to share a little more?
Yeah, it was, but this is all the video I have. I also have an audio recording of the whole presentation, but I'm not sure about rights and I won't publish it publicly (moreover, I think the presentation he gave was a standard one, so not really specific to our day).
This ways is moneys . . ! Bleach into small cup then all your tooth brush head in for few hours . . will be clean like new .
