New parts - VzBoT

[@Roots747]

Thanks Vez for all the work on the printer, currently building the vz330... That filament sensor will be usefull to setup an MMU, I was looking into an extruder that would be able to achieve that capability in the future. I really enjoy the work that the Mellow team is performing on their product lines, very interesting ideas coming up and i really do appreciate the openness shown on your discord to ideas to improve their products

[@tytechguy]

Awesome man! So glad to see new parts coming for the VZBoTs. Albeit it costs me a foutune owning 3 so I have to upgrade all 3 every time something drops. Lol I have also been developing some new parts for the VZBoTs in the way of aluminum parts. I don't have the ability per se to develop electronics but I can repair them. That said I'd like to drop some of my ideas and CAD files by you sometime Vez. I think you may like them. As always great to see you posting new stuff! Keep up the great work Mellow/Team Gloomy and the VZBoT Team!!

It's great to know the Kraken can be tested with those .

[@mikestewart4752]

That driver looks sexy. Looks like an RC Electronic Speed Controller.

[@Lidocain777]

Sexy for sure. Yet ... WHY add neopixels on these ? I don't get it ...

[@jeremiwebb7519]

I’d love a printed solution for the 330 for the bearing. I like higher tension and think stability and rigidity it can help with prints overall.

[@3Dgifts]

Any way to upsize this printer to 350mm x 350mm or 500mm x 500mm build plate?

awesome goodies for sure

[@jezdimir2007]

Hi Vez. Any chance that mellow can be convinced to release the aluminium lower z bearing mounts and z motor mount as a s separate, standalone bundle?

[@Alex_Railnolds]

Hi. Have you tested the filament sensor yet? The problem I have is that the jam sensor is constantly active. I tried different settings for the connection pin, but the situation did not change. Does this sensor work correctly for you?

[@kotqrka]

Should we install these drivers directly on motors?

[@simontanguay3619]

Excited for these new parts! Your videos have inspired me to go AWD on my Voron, currently assembling the new gantry (going with Monolith + LDO Superpower motors). For the drivers, I got a very good deal on the TMC5160T Plus (the big ones) from BTT. The new Mellow drivers look very similar in terms of specs, but more compact and with some added bells and whistles. Any opinion on how these two compare?

[@Vez3D]

I would guess they offer about the same. But with more bells and whistles like you sais. Temp sensor is nice :)

[@grasstreefarmer]

Looks great! I love that we can all have access to well made aluminium parts at a very reasonable price thanks to the popularity of the high end DIY printers and all the work that has been put into the designs. Does the slot for the top bearing on the motor mounts not defeat the purpose of having it there though? If the bearing can move its not supporting against the tension? I get that the slots need to be there because the motor has to move for tensioning adjustment, but isn't that just a fundamental downside of using motors to tension instead of separate tensioners.

[@Vez3D]

There is a "locking" bolt that will lock the slider once tensioning is done

[@Vez3D]

And yes..it would be ton easier to have a tensioner elsewhere than from the motor...but the current design do not allow this. On a next printer this would be how I will do it. This the issue with a printer that keeps evolving and we tried to find solutions. When it started the tensioners were on the printhead and we scratched our heads to move that away and NOT lose printing space. The only solution was to use motor to tension it.

[@al1sa920]

Looks sick af

[@BH4x0r]

i wonder what those non-trinamic drivers would do like the SL2690A's, probably would be way louder and less great to use but 90V bro 😂 i wonder when theres gonna be a 100V Trinamic driver, and what those could do lmao

[@darkmann12]

would love solder pads as well as/instead of screw terminals tbh

[@pasch3483]

Vz Filguard detector sensor link reaches a dead end....mellow does not respond in discord for information

[@chuuba_lover]

obviously the drivers are isolated from the 3D printer board right?? because you can't send 48 or 60 volts through the 3D printer motherboard

[@996pat]

Only the drivers will receive 48 or 60V and the motherboard will just be getting 24V. There's also no risk of the higher voltage going back into the MB so the risk of damaging it is almost non existent

[@TheNamelessOne12357]

Why only 60v? There are Leadshine drivers capable of 110VDC or 80VAC.

[@chuuba_lover]

Because those ones are incredibly noisy

[@TheNamelessOne12357]

want to test with the kraken cant wait

[@pixel_vengeur391]

Ooh, shiny new stuff :O Will the kits be updated with these new parts once they land?

[@Vez3D]

Probably. We will see how it affects the cost

[@UNVIRUSLETALE]

Those driver upgrades are getting a bit out of hand, water-cooling, 60v 6a and RGB? Wouldn't it make more sense to just go to servos/bldc at that point? 🤣

[@Vez3D]

My experience with servos on a corexy was not great. It is hard to keep motors from fighting each other and causing ripples/artifacts. Maybe with higher encode ones and more expensive ones ? I didn't test. I guess one day it will come :)

[@UNVIRUSLETALE]

​@@Vez3Dthe hard part is the implementation, klipper still doesn't natively support foc, a man can dream, at least

[@BH4x0r]

​​​@@UNVIRUSLETALEwell hooking up an odrive is almost like hooking up a tmc stepper driver externally step dir and gnd is pmuch all you need apart from some oDrive configuring and hookin up an encoder obviously even if Klipper could support FOC directly, that would be useless as i highly doubt any mainboard mcu is powerful enough to handle more than 1 foc instance

[@BH4x0r]

​@@Vez3Di think you may need/want some magnetic encoders, most are 12bit res or 4096 steps per rotation

[@Vez3D]

@BH4x0r the one I tested were 2048. But i see odrive now has now 20480 res. Maybe one day i will try again

[@sabahoudini]

Why not design it with the second motor upside down and use regular shafts? This is how the voron guys do it. It will be even less tension on the motor that way because the pulley is closer to the motor and you can tension belts to gates specs achieving a lot more accels.

[@staticred1559]

Some other upgrade in the future coming, which needs thats space 😊

Do you plan on just leaving the documentation for Vzbot unfinished forever while you just keep on iterating?

[@Vez3D]

These will be basically same install process. But i get your point. The doc has been an issue and we should address that. Videos been posted of assembling too but yeah...i know. We would need to put more time on the doc on our copious free time :p

60V at 6A.... thats like 2hp with a awd setup..... wild

It would require a total new design. And might be easier to use 3030 to have space for that

@@Vez3D you’d just have to basically space out the parts and modify the toolhead posts, doesn’t seem that hard to do. And know you already have motor mounts with double shear 😃

I've commented on another one of your videos about the excessive cost that Mellow are charging for made in China parts, price reduction should be what you need to talk to them about and there is one simple way to do it, when parts are machined you should only machine what adds value to them, the VZbot logo does not, you are suffering from what I perceive as overbranding, I'm currently in the process of building the printed version and have been going through the cad files to remove all the VZbot logos from every single piece, it feels like Chinese branding problems of for example when they manufacture a cheap generic motorbike to sell to India and cover it in useless plastic sporty looking bits give it an only cool in India brand name like "Bloodfart Bandit Boy" then proceed to plaster the brand name on every single space available on the motorbike, it looks cheap, the lines are ruined and it distracts from the overall appearance and adds no value to the bike, it's almost like machining go faster stripes into the hotend assembly just to make it look cool. Yes, you're going for brand recognition but what you are getting is brand oversaturation.

mellow is the worst aliexpress 3d printing manufacturer

[@chuuba_lover]

why?

[@NowLoadinG7-]

[@orbiterprojects]

Please do not take this as a criticism just facts. 60V is dangerous voltage please do not emphasize such product for DIY. Obviously in China INSUCO regulations are not a concern. 60V DC and 30V AC is not touchable for humans, its lethal...Obviously 48V and 60V supply will generate at the motor phase that amount of AC voltage which is above the 30Vac limit which is considered safe. Secondly heat is not transferred differently due to higher voltage, Its the same, components are having thermal design requirements, glad that this information arrived to some Chinese manufactures as well :). Hope these products are coming with CE, FCC, UK certification including INSUCO testing (I doubt that since I do not see those projection features in the pictures) otherwise they are pretty illegal. For those do not understand what INSUCO means is insulation coordination - which basically means design measures to avoid injuries / death by electric shock.

[@Vez3D]

60v is obviously optional and people know its dangourous. But i will make sure Mellow adds warning on the doc and listing for those who wants tk run 60v. 120v AC is also dangourous and we all do our own wiring, and use AC on bed heater etc...and we are all aware of the danger. Safety should be a priority and those going HV should know the risks

[@orbiterprojects]

@@Vez3D Warning is not enough, design must fulfill INSUCO requirements. For any injuries which may be caused by the product use the manufacturer is solely responsible. This means manufacture must do design measures, must provide safety and user manuals. Honestly this is not anymore a DIY area its for professionals. I had lots of discussion with LDO for designing such devices and I personally refused to design something which is out of the human touchable voltage range which is ~30V. Depends which standard you follow but mostly accepted that voltages above 30Vdc can cause electric shock and over 60Vdc or 30vac depending on the frequency range is considered lethal. In this case would mean the product must be designed in a way that none of the 60V area of the device is touchable by user. Plus additional isolation measures which ensures in case of failure of the device will not lead to electric shock touching the touchable areas. here we have aluminum housing which serves as a heatsink, failure of any components inside shall not lead the aluminum case to have 60V.

[@riba2233]

Oh cmon it is not that bad, 48v was considered a safe voltage and y0u would have to do something special to get zapped by 48v range. I would still consider it fairly safe and if y0u do get zapped somehow it will just be a warning.

[@Vez3D]

@@orbiterprojects it is not my product here. I am just showing it off.. and mentionning it can do 60v. I personally will stay on 48v and will advice everyone to do the same.

[@orbiterprojects]

@riba2233 Yes, 48V is not lethal, just dangerous, and care must be taken.
