You should consider adding a tiny (
This is an excellent idea
I installed the beam yesterday. when I first read your comment, I thought it was very good idea, but then I installed it, and saw that will all the bolts loose, there is very very minimal play in the rail for aligment. so you either just push the rail back against the bolts or to the front and it will be all aligned, but the play is so minimal that I dont think its even needed. So thtat aligment edge is probably not worth it in my opinion :) oh btw... it made a bigger improvement than I thought :O
honestly in CNC machines to align the various axes a comparator or a probe is used or recently the laser has taken over (I use easylaser damalini so I also have a printable report) returning to the 3d printer or any artisanal CNC use of one or more comparators cents should be ABC
If you're already making custom extrusion dies, I would look into making small interior corner gussets to allow you to thin the tube walls while maintaining strength. Look up REV Robotics' max tubing for reference
You should consider flowdrill/thermal friction drilling instead of regular drilling, this can "add" thread length/thickness and also cold form tap the tread instead of cutting. This way you can get the most out of the lightest and strongest option. Also some viewers mentioned a recess for rails to make sure it is parallel a nice idea (it will depend on the rail size I know). Cool product! I am curious to see how well it works and what resonances the printer should avoid. Keep up the good work!
I don't know if flow drilling works on aluminum but it's worth a try
Great work Vez... Re: "groove" I believe the word you're looking for is "ridge"
We used custom extrusions on the Powercore! LOVE CUSTOM EXTRUSIONS
I have the black beauty of it. It fits perfect and looks pretty good in my Vzbot. 😊
Ah man, I wish this was available for the voron :D
You clearly need another VZbot, a black one so you can keep one close to the kit config while you play with servos or whatever else on the other.
Thank you that after the release of this video, the prices for Aliexpress soared for all parts for vzbot
no.. price is still 34$ usd.. nothing changed. And normally Mellow talk to me before changing prices.
Get yourself some aluminum screws and you are a breath away from weightless!
Do you have only parts where the belts run through? I mean: Beam, brecket L+R for Beam, Corners for belts?
So the complete XY movement of the printer without printhead.
Awsum!
Beauty.
Géniale comme design!
Hi Simon
Is this beam only suitable for mgn12 rails? Can mgn9 rails be installed?
@sawo74 its mgn9
Aw man , not first. :P Great new design!
Just a quick question, do the lead screws of the Z axis ride on a bearing so they dont fall down with the weight of the bed or are they against the bottom plate of the printer. I looked at your Z axis installation and I dont really get it. Amazing machine man, I am currently designing my own coreXY machine for fun and it's SO much work. Respect!!
They are held by a bearing
Is this part of the mellow kit yet or is it still the CF version?
still cf but soon to be part of the kits
I don't believe all the material on the linear rails is required, reduce weight
Awsome
btw, the English word for that “channel” is “boss”, like the opposite of emboss
"boss" is not the opposite of "emboss". The "em-" prefix usually means "to do" or "into". The Old French origin of "emboss" is derived from "boce", which is a pertuberence, but English does not use "boss" to mean pertuberence. The word he is looking for is probably "pertuberence" or "ridge", which is the opposite of a "channel".
@@Aethid "English does not use 'boss' to mean pertuberence" is incorrect. Search for "boss feature", first result:
en.wikipedia.org/wiki/Boss_(engineering)
"In engineering, a boss is a protruding feature on a work piece."
@@Aethid "ridge" is a really good english word for it, i do agree on that (-8
@@Aethid PS I wonder if emboss predates the use of boss in engineering?
fa real? Nice
how do you convince manufacturers to make loq qty customized product :)
Great, nothing for 400 machine from Tronxy 400?
Looks very nice. Looking forward to your real live test results. Love the 100% Machined look, simply that should make it at last 100% better ;-)
Can this be made in 622mm length for my RatRig V-Core 500mm lol
Or my Tonxy x5sa 500mm
What's the next part your gonna try optimizing?
when using linear rails do you still need corexy or can you get away with h-bot? h-bot would save some weight...
I much prefer corexy over hbot for the way belts are working.
Are you associated with F3D at all? Been waiting for the 330 beds to come back in stock.
I have this installed on my printer already!
I didn't get the wrench :(
Oh man you follow my mind, I just made one for my own printer like 5 days agos 😭
I wonder if we can try some titanium gantry design, they are heavier in turn of density but you should be able to cut a lot more away due to their superior strength compare to aluminium. But their main benefit should be stronger threads for the rails and thermal expansion is less of a concern when paired with stainless steel rails? Ofcourse it will be more expensive for both the raw materials and machining.
titanium linear rails would be more useful then I think, I did some basic math and even with a 15x15mm 1mm wall tube the bending distance at 20000mm/s^2 is only 0.07mm so the stiffness of the gantry is not an issue.
Edit: That is with a 500g hot end in the middle of the beam, worst case scenario basically.
@@woutervossebeld4664 yep it would be worth exploring I might try to design one and test one and use my work cnc machine to machine one out see how it goes
While titanium is a stronger material, it's worse when looking at strength and stiffness to weight and thermal expansion is worse, it expands about 50% of stainless while Aluminum expands about 33% more.
Ofc this depends on what type of alloys you use, but as a general look at it, Titanium isn't a good choice.
Now if you're able to make a linear rail out if titanium to match with the gantry, it''s going to work just fine, though you run into the same issue as aluminum rails, it's a "soft" material and longevity will suffer. You can probably use real bearings though on a Ti rail, aluminum rails uses glide bushings and is a joke compared to stainless ones, they bind constantly on a 3d printer. (I've tried lol)
I've not found thermal expansion an issue. With the machine soaked to 50C I just used two screws to attach the rail (at 1/3 and 2/3 along) and found that gave me very flat results.
@@MrJofArnold On a VZbot it might not matter so much as the gantry is relatively short, but I can notice it on my VC3 500 with the standard MGN12 rail and 2020 extrusion. It's definitely not a major issue, but imo it's worth considering.
on regular printers they have an optical encoder to move the print head do you think there would be any benefit if it is used for 3d printing heads perhaps more precision and speed
perhaps it can be integrated into the rail it self
Aluminium is light, no point of milling it. You'd better mill rail and carriage, they are much heavier.
I dont understand your point here. yeah its light.. but you mill it to have a flat surface to bolt the rail. You mill it to be even lighter, because no point keeping metal where its not needed
:) Rail and carriage are not easy to mill.. and have a chance to deform the rail. But we are exploring the idea
@@Vez3D Rail and carriage are much heavier than aluminium profile. If you decide to mill than they should be first candidates to reduce weight.
Of course, steel is slightly harder to mill, but when difficulties stopped you?
@@Vez3D maybe titanium rails are an idea, titanium is of similar hardness as steel so it wont deform or wear as quick as aluminium with the bearing balls rolling on the surface, its also a lit lighter.
I was planning to build a Voron 2.4 and purchased a Octopus pro with 6x2209 and two high voltage steppers. Can the Octopus be used on the VzBoT? I really like your approach of a moving Z bed and liquid cooled heat break. My budget is limited to about £70 per month so this is going to take more a year to get everything together. Any comments are welcome thank you.
yes you can use an octopus :)
@@Vez3D Thank you how many high voltage stepper drivers would you recommend?
Mgn9 on 330 still with this rail? I have one in my cart .
