As promised we publish today, 3 january 2018 the first variant file.
Other variants will follow next days.
Remember to download the parts list for you variant to know number of each cut for each part and screw and nuts number.
8 February 2018:
Correct a small measurements error on YM11 part, now last version of this part is named YM11B and replace original YM11
Variants for Igus upgrade will be upload march 2018
Many thanks to Marcel LeMay, who cut and test first Tatara A6 prototype.
This text is a Draw
This is a steel frame improved design for Anet A6 3D printer. (for ANET A8 Swapit go here: https://www.thingiverse.com/thing:2736479)
My self and Tommaso Collini (https://www.thingiverse.com/musta/about) we tried to implement easy solution to solve common issue we found on Anet A6/A8 printer and most of cartesian printers. We believe Tatara frame is the best steel frame you can build.
In our design all parts are inter locked that ensure great stiffness and perfect geometry on all 3 dimensions.
What is special in our design:
- XY frame to make all build more rigid, this is a major improvement against all others Cartesian Steel frame that let you push printing speed to 150-180mm/sec, 20-25mm/sec2 jerk 1200 mm/sec2 print acceleration with good quality
- We add the option to add 6 LEVEL FOOT to level the printer
- Nyloc/Lock nuts compatible by design
- many small improvement that make the frame incredible rigid with virtual no resonance during printing.
- Damn heavy, more than 9Kg only for frame. Because we are not overseas seller's, weight is not a problem but a feature:
-lower center of gravity
-weight leads to a higher inertia and therefore less high-frequency vibration
Steel is the material that gives the best ratio stiffness (young's modulus) vs cost/volume.
To achieve same stiffness with other materials you need to use, at least, a sheet 3 time thicker.
To be manufactured of carbon steel (requires painting) or stainless steel.
We strongly suggest the use of a material with a minimum Young Modulus of 196 GPa ( double check it before you get your frame cut).
Is designed for 3mm thickness (clearance is 3.2mm so maybe you can also use 1/8"-> 3.175mm but we did not try)
people who sell Tatara frame on internet don't give any % to the designers (us) then if you enjoy the Tatara frame ( or if you make money with it)
can be kind to TIP
All measurement are the same as Anet A6 and you have to change only the frame and maybe the screws (depend what length of screw you get on your original Anet A6).

The draw is done from scratch, by your humble servant.
if you use anet board with anet stock FW the Y motor go to the left and nOT to the right like in the images, if you use marlin as FW you just need invert direction of Y motors in your FW
### REMEMBER TO "Electrical Grounding" the steel frame !!!!!! ##
