Hi all, sorry I have not seen this earlier but maybe I can help if it still has not been solved.
The videos don’t open for me for some reason but the photos are probably enough.
Please update me with what is the current state of this machine?
Still in need for advise?
If tools are difficult and expensive there are other ways to make it work, just update me and I will have a look. I am a machine design engineer and worked with mechanical engineering for over 40 yrs. I am sure we can get this right if you still need help.
Kind regards,
From the video it looks like the portal frame is twisted compared to the bottom frame plane.
Especially if you look at the portal top horizontal extrusion and compare it to the bottom horizontal extrusion.
So even with your aluminum corner pieces and the printed parts there is a chance it is not exactly 90°!
We even had aluminum corner pieces that weren’t 90°…
So measure each and every angle and distances from the extrusions to the other parts.
I don’t know what this is where the printer sits on.
If this is kind of a very plane stone surface you can check whether the portal and/or the bottom frame is bent/twisted.
Then check whether the two linear bars that are the Y axis define a single plane (X, Y) and so on.
Hi @LifeOfBrian & @3dcase
Thanks for you’re responding
Hi Farzad,
Good photos are better as a medium to show what is going on. Your videos are too large and don’t open for me. Googledrive says it is too large and cannot scan the file.
Better tell us what you have done so far and what is the latest situation.
hi from now on i will upload photo
but videos are virus free
It’s not explaining everything I asked.
You never answered
I’m interested in the lower circle of my picture (where you mounted your Z-frame), PLA probably? Moisture and temperature will change every day and also PLA. No wonder that thing is twisting. You need metal here for solidity!
I have the impression, that you made a poor decision constructing the Z-frame. I would have put the frame together with all the profiles turned by 90°. That will be much more rugged against twisting. Also you would be probably able to mount your aluminum angles!
Your aluminum profiles have a dimension of 20mm x 40mm? Do you have the specification of the profiles? Who is the manufacturer?
Maybe I can organize some angles for free for you. I need the specification of the profiles for doing that. I’ll ask my Iranian buddy how to ship it. I’ll pay the shipping, if I can organize the parts for free. So, many ifs 
Hi mr hec 14 thanks for your replay
about z axis woble(no its very rigit)
and about material (its abs)
(i alway do print abs because its cheaper and much beter)
About aluminium extrusion (only information that i have about them is they are 20*40)
About manufacturer of aluminum extrusions (we dont have any data about it ( usualy you cant find good quality stuuf in iran )
(Its been 3 month that iam trying to find mic 6 aluminum plate for my build plate, no matter where i call they say mic 6 !!! What is this !!! )
If you mean “rigid”, then I don’t understand your problem!!!
Could it be, you are just talking about the flatness of your bed?
Yes z axis is completely rigid
But as i showed in 4 and 5 video i did find out that none of the aluminum extrusions are squre cuted and also some of them are twisted !
I bought some new ones but there not squre cuted to
Iam going to find an edm machine for cuting them perfectly
I will keep you posted
And also about bed yes i have bed problems too
My bed is 6061 and its warped very bad duo to heat
I did some research about it and did find out that it shoud be mic 6 and none of the
7xxx
6xxx
5xxx ( 5083 from this series is Exception )
4xxx
3xxx
2xxx
1xxx
Aluminum series are good for this application
Problem is we dont have any of thr following material that can be used for 3d printer bed
Mic 6
Alpase K100-S
Alca 5
Vista Metals ATP 5
Alimex 5083 (vendor is very important on this one)
(Sorce: voron web site)
I did find some 5083 ( it shold be casted )
But in iran i did find it at 100mm thickness and above
Okay, got it. I’ll have a look, what I can organize.
I’ll need you to measure this at your profiles!
How thick?
I might find an aluminum plate to ship with the angles. What dimension should it have? Though, I will not know which kind of aluminum it will be!
Hi there
In this few day that i wasent online, i did some work on my new aluminiom extensions and made them exactly same size with help of some of machinest in tabriz ( one of the industrial city’s in iran )
( it was expensiveas ! He did take around150 usd for simple cnc work ) but there not perfectly squre as i was expacting
And the strange thing is this
When i put them near each other (from the place that end mill cuted them ) there are perfectly square
But when i flip one its not !!
Is that much of error is bad ? Shuld i work on in with a sand paper ?
Or leave it as it is ?
About the measurements its 6.25 on my aluminum extrusions
About the plate my 3d printer plate is 25cm by 25 cm
It should be 8mm thick
Based on the things that i read on voron website it shoud be one of these aluminum grade
Also about the cost
The problem is iran bank system is isolated from rest of the world and i cannot transfer you any money
Only thing i can do is send it with cryptocurrency
Hi Farzad,
sorry, I read it days ago. I was just occupied by other things.
Expensive bummer, but I guess it’s not that easy in your country. Can you complain to that person?
Yes!
No, I fear you need a new one. Find out, which one is twisted (hopefully not both).
Why 8mm? You got a bed slinger. That’s a lot of mass (heavy)!
No costs! It’s for free.
It will be 3 beers in my favorite bar. Won’t kill me and I like your enthusiasm 
When I said
That stuff lands in the garbage at my company. Costs me nothing.
Again
I don’t know the specific material! Just try it, its for free!
Think about the thickness of your bed plate. I wouldn’t recommend 8mm!!!
Let me know.
I found parts for you, but…
Do me one favor. Please give me your measurements of your profile.
Please take this picture and fill in all dimensions in a different color!
Since you live in a country, that does not belong to the western world, your profiles may have completely different dimensions.
6.25mm does not fit to my profiles!
We have to check that up, before I’ll send you anything. Does not help, if I send anything, which doesn’t fit!
hi mr hec 14
i did but because they bribe the inspectors, nothing happened
(except i lost one month salery)
this one’s was most expensive and also best ones
unfortunately, all of them are slightly twisted ( i did cheeked them with knife edge square)

[/quote] i used thin ones they Easly get warped (bent, twisted due to heat)
i wont forgot your good work thanks
Hi Farzad,
Triple bummer, sorry.
Forget the Mr.
I wouldn’t recommend more than 4mm. 8mm has the double weight load for your bed slinger!
Let me measure my parts against your drawing.
8mm is too much, think about it. I’ll get back to you.
hi !
in iran it’s been taught to us that we should always call mr with the name of the people whom older than us
and if i don’t do that i kind of feel rude 
recently i began working on new design about my 3d printer and i did study the best bed slinger 3d printer for that (pursa mk 4) they are using a 4 mm heater bed (as you told) but for y carriage there using a 6 or 8 mm (didn’t find exact number) but for making it lighter they just used some hexagon pattern in bottom of y carriage
Iam going to buy a aluminum plate (5083 grade or maybe 6061) and machine it with cnc just like that!
(pursa use die casted ones (that’s pretty smart because it performs much beater against heat) (and also, they did not used any spring like us they just used some aluminum spacer for making it rigid)
about the heater bed itself they did drilled 9 holes on it and used some bevel head scrow for preventing bed from waping and deforming againts heat
i did find a design of pursa with aluminum extrusions (name of it was pursa bear update) it was so smartly designed (they did used short length aluminum extrusions but at the same time they did raised up bed so it can move above the frame (without needing long aluminum extrusion) ( it use 17 cm less than my design)
it’s so good because printer will get much less effect from aluminum extrusions Bending
i also did some modification on it and designed some Custome brackets and cut them with fiber laser from 5mm steel
the thing is they are rusty and maybe they not very good at surface
so Iam going to find a surface grinding machine to make them perfectly as is can be
