October 2024: The “M:I - Mission Impossible” edition is on-line !

• A chainmail on the left side. This object, in addition to being able to detach itself easily from the rest of the model, must be able to move in all directions, adapting to the surfaces. Warning: as it is made up of small links, handle it with care.
• Five horizontal bars in the middle of the model will serve as supplementary measurements:
  These on the left must be 0.8, 1 and 1.5 mm thick while these on the right should be 2 and 3 mm.
• The letters “TGC” (the great calibrator) appear also in the middle. At least the first and second (from the left) MUST be perfectly readable for the test to be valuable.

REMEMBER: Set all line widths to 0.4mm ( the profile is already set on it but better check before printing…)

CORRECTIONS:

• The arms connecting the hinge to the base have been reinforced.
   

September 2024: The "DJANGO" edition is finally out and it mainly has 3 new features:

• The 20° XTREME overhang has been moved at the end of the front left square
• A vertical bar connected to a spring can be pushed inside the front left square. This is very important to determine the elasticity of the filament and his resistance to bendings
• The DJANGO chain is at the back. It is a print in place chain who can be … “unchained” at one side. This part should be completely free to move. it will serve as a test for the compactness of the layers and for printing small parts at 45°

This 5th edition of the great Calibrator has been also corrected:

• A part of the hinge seemed not to be connected to the base. Now it has been done and also reinforced.

Happy printing mates!

…Take also a look at my other models…

EDIT: A new profile with a model of the monster edition for 0.6 nozzle users has been added (Read the description in the profile please) . The DJANGO 0.6 nozzle profile will be soon available too. Enjoy

V3.4:

• The Overhang and Bridge tests are now stuck to the back wall to make them more secure on the base. The ability to read these two tests remains unchanged, in fact the vertical part, now attached to the wall, is of no particular interest.
• I slightly increased the distance of the spheres from the base below them, now it should be easier to allow their movement.

Other changes to tolerances are not expected. Your printers must be able to create the model in its entirety (apart from the antenna), i.e. all elements should be present. 
The detachment or non-completion of a part of the model may be attributable exclusively to the printing conditions/calibrations (printer adjustment, filaments, etc.).

Thank you so much for your collaboration!!!

PLEASE READ WELL THE FULL DESCRIPTION AND DON'T FORGET TO GIVE INFORMATIONS ABOUT THE FILAMENTS USED TO PRINT THE CALIBRATOR. THIS IS A VERY USEFUL INFORMATION TO SHARE WITH EVERYBODY !! THANK YOU!!

Hello friends, I promised, I did it !

V3 of THE GREAT CALIBRATOR is out, ready to print and to let you discover other qualities of your printer !

What I added:

• CLIPPING SPHERES with tolerance from 0.1mm to 0.4mm
  These spheres should be extracted from their housing. In this case the test doesn't refer only to the printer quality and precision but also to the quality and properties of filaments. In fact to let the sphere been extracted and possibly repositioned more times, the filament has to be a bit elastic and not brittle.
  So if one of these external spehere comes away braking one or more of its lower parts it means the tolerance it's correct (sphere removed) but the elasticity of filament isn' suitable for this kind of printing.
  I found this update a very nice way to have informations on different subjects…

   

• ANTENNA four arms and bridges

   

  BEFORE LEAVING YOU FALLING INTO DEPRESSIVE MOODS I prevent you that printing antenna is very difficult to achieve 😂
  Let's say that this is more a “disturbing” antenna. It is in fact positioned between the two bridging and overhanging tests.
  The pole is only 1mm thick and, when printing, if not enough calibrated in z axis or filament flowing, the nozzle could start to knock the pole and break it during the printing.
  The antenna also test the skills of your slicer (bambulab studio, orca slicer, prus, cura etc) verifing if the pole printing is done between or before or after the bridge and overhanging test. Than it should be capable of build a bridge across its four arms.

AT THE BOTTOM OF THIS PAGE I POSTED SOME PICTURE OF A FAILED TEST….

EDIT: I ADDED THE RESULTS AFTER A SHORT CALIBRATION

-TEST FOR ADVANCED PRINT IN PLACE TOLERANCES:

Four ¾ spheres must be able to freely move in each direction. Extracting spheres expected in the next version!

SUDDEN OVERHANGS FROM VERTICAL WALLS

this overhang test found on the back consists of two tabs at 65 and 75 degrees that protrude directly from the vertical wall. This obviously changes because it is a sudden transition and not a gradual transition like those behind them...

The rest is the same as v1:

- EXTERNAL WALLS/RECTANGLE/CIRCLE: 
They are all 0.80 mm

- RECTANGULAR BLOCK 10 mm x 5 mm

- RECTANGULAR BLOCK 15mm x 5 mm

- THICKNESS AND SPACING:

From a minimum thickness of 0.40 mm to a maximum of 0.80 mm with increments of 0.10 and from a minimum thickness of 0.10 mm to a maximum of 0.40 mm with increments of 0.10 mm

- 9 STRINGING CONES: not parallel to each other to test the maximum loss oozing from your nozzle

- NUT AND BOLT:

They have a tolerance of 0.10 between them (attention: the thread does not correspond to a precise standard, everything is built with 45° angles to facilitate printing)

- OVERHANGING TEST:

An initial angle of 45° and then moving on to extreme angles such as 65° and 75°

-BRIDGE TEST:

Same values as the overhanging test but with side walls to form a bridge

- TOLERANCES TEST: 5 pegs are printed on site with variable tolerances, from an extreme of 0.05 mm to a rather evident one of 0.20 mm.

TO USE THE TOLERANCE PEGS, once the model has been removed from the printing plate, simply PRESS THEM DOWNWARD and, if the tolerance is satisfied, they will go down a few mm and will be unlocked enough to be in measure to be withdrawn from their seats.

A well-calibrated printer should be able to:

HAVE ALL WALLS with dimensions very close to 0.80 mm (+/- 0.05 mm),

PRODUCING A WORKING NUT AND BOLT WITH MINIMUM EFFORT,

PRODUCE excellent quality OVERHANGING and BRIDGES at 45° and degrading up to 75° (without failing to write the number at the top)

OVERHANGING in the back of the model must be comparable withe previous ones.

FREE ALL PEGS at most, except the 0.05 peg (actually very difficult to obtain)

OBTAIN SATISFACTORY MEASUREMENTS in the two 10 and 15 x 5 mm parallelepipeds

HAVE THE SMALLEST STRINGING (as possible) between cones.

FREE every sphere on the left side

Remember that a good calibration of flow and pressure can give optimal results!

Do your tests and post your photos! And be really proud if you manage to remove the 0.05 peg!!

EXAMPLE OF GOOD RESULTS:

This is an example of a print of THE BIG CALIBRATOR v2 with a filament that hadn't any adjustement and calibration before.

• The .05 peg obviously didn't remove, and the 0.10 has been removed only by beating with a little hammer on it.
• It clearly failed at spacing 0.10 and even 0.20mm (the walls under the .05 peg…).
• The Bolt and nut could barely work but the efforts is too high and it would risk to break the bolt.
• The Spheres was all glued to the base and I needed a little plier to free them but, as you can see, the .10 Mechanical PIP tolerance failed.
• The dimensions was a little oversized on almost every wall.
• The Overhanging and the bridge didn't failed, they were good instead (… but my big fingers hurted the leftmost one and i miserably broke it) :D
• No stringing.

This probably means that the filament has a slightly high flow rate and need to be adjusted…

The pressure wouldn't seem any bad !

A VERY BAD, FAILED PRINTING:

as you can easily see spaghetti house ! The print is a failure!!

Stringing ? No… probably a part of spaghetti brought here by the nozzle :/

Not able to maintain an “acceptable” micro overhang down the spheres… lot of doubts on their functionalities…

Starting thinking this filament has some issue… need calibrate the flow ? Strange… because it didn't even do the 45° overhanging. If te flow was high it wouldn't fail at 45° …

As I imagined … the bolt can't fit the nut. The filament is printing in a bad quality. It surely will need some calibration (if possible… because some filament never had good possibilities)

Only the 20 and 15 pegs have been removed and only the 0.4 left sphere could be detached to give a (very little) mobility.

The new test of the removable spheres was the final element to convince myself that the printer did a good job but the filament didn't… Even if the 3 sphere has been removed they broke too easily some of their legs, even at 0.40 and at touch i felt also that the product was kind of soft…

ALL THE WALLS WERE DOWNSIZED BETWEEN 0.74mm  AND 0.76mm which is not dramatic but obviously it reduces walls consistencies and adeherences and i clearly could notice that the lines was stretched along the path, indicating probably a difficult regular flooding and so producing thinner walls (in fact they are thicker near the beginning of layers).

RESULT: I won't probably use this filament for mechanical parts even if I will try again after a complete calibration. The printer is ok, the A1 mini gave me already the same results of a P1S (look the good gray model posted before).

I will use this filament for artistic models, its colour iss nice and the effect of changing color is awesome.

I then calibrated the flow, the temperature and I forced the K Factor and Here the results:

THE GREAT CALIBRATOR AFTER A SHORT CALIBRATION

The overhangs are there,The nut fits the bolt flawlessy, no stringing and only the spheres 0.1 failed .

The pegs were removed until the 0.10 (but i forgot to take the 0.1 peg out in the pictures) LOL 

As I imagined, the antenna didn't built up :/

 

• Walls dimensions are almost perfects !!!!
• We can even barely distinguish the division between the first two vertical walls (unexpected success)
• The parallelepiped dimensions… WOW!!!!

That demonstrate how things could change in a while ! (anyway, as before, i won't use this filament for mechanical parts 😆 )

Have a good printing and good fun !
