Highlights

The Calibration Flower is a tool for calibrating 3D printers, with new updates to the software and minor changes to the flower itself.

The Calibration Flower has been renamed to Cauliflower due to its resemblance and the wordplay.

The calculator software has been updated with new interpretations of results and implementation guides.

The calculator now includes a feature to calculate steps per millimeter for calibration.

Commands for fixing skew have been added, specifically for ReprapFirmware.

The calculator now offers an alternative skew method for Marlin firmware, addressing previous bugs and reducing errors.

An M852 command has been implemented for configuring the SKU in Marlin firmware via Gcode, simplifying the process.

Minor changes to the STL file include chamfers being changed to rounded fillets to prevent measurement errors.

A LibreOffice version of the calculator has been created for users who prefer open-source software.

The calculator does not currently support iteration for skew correction, but a single run should suffice for most users.

The downloadable files have been streamlined to focus on the Cauliflower and calculator, removing less utilized files.

The scale of the Cauliflower is typically set at 100mm, suitable for most consumer printers.

Conditional formatting in the calculator helps interpret measurement accuracy, with green indicating less than one millimeter of deviation.

The calculator aims to determine the actual nozzle movement and ensure the printed line is in the correct place.

Skew is measured in degrees and does not change with scale, making it a consistent measure across different print sizes.

Printers with built-in calibration methods, like the Prusa i3 Mark 3, may not require additional calibration with the Cauliflower.

The Prusa Mini does not support firmware calibration for skew, making the Cauliflower less effective for this model.

Unused Cauliflowers can be repurposed as coasters, providing a practical use after their calibration function.

hello everyone and welcome back to the

channel today we're taking another look

at the calibration flower as i'm going

to run you through some of the new

updates we've got in the calibration

software as well as minor changes to the

flower and then we'll run through some

tips and tricks on how to use the

calibration software i say software

calculator that i've made and then i'll

show you a cool little use for these

that you can do after you've finished

printing and calibrating with them

so the first thing i just want to recap

if you don't know what this is you

haven't seen it before then you probably

want to check out the video which i'll

link below or somewhere in the cards

that's probably a good idea and you can

learn about the calibration flower as

this is called

which is basically for calibrating your

printer and that video explains all the

problems that we've had with cubes and

things and this is just a bunch of

opportunities for improving things to

make them a little bit better it comes

with a calculator you can buy it on the

website all that kind of stuff but today

what i want to focus on is some of the

upgrades and changes i've done since

that video to make it even better than

it was before

so the first thing and maybe the most

important is that we're going to rename

it to the cauliflower

so obviously like cauliflower bit like

cauliflower

bit like flower calibration flower get

it yeah cool it's now called the

cauliflower now that we've got the

really important thing sorted let's move

on to updates to the calculator so you

can see some of the changes i've made

there which might be useful for you if

you thought that it might not work for

you before now it probably will so the

first thing is we've added a bunch of i

say we i've added a bunch of kind of

interpretation of results what they mean

and how to implement there's a bit of a

extra guide just within the calculator

to help you get the most out of it i'm

also going to run through some extra

stuff at the end of the video just in

case you want some more in-depth things

the next thing i've added is down at the

bottom of the calculator i've added a

zone four steps per millimeter or

rotation distance so before it was just

calculating the error which was what we

find using the cauliflower but now it

actually does that calibration of the

steps per millimeter for you so you've

got those values that you can implement

the next thing i've added in terms of

fixing skew is commands specifically for

reprap firmware so so before i had some

for marlin and some for clipper but now

we've got a little reprap firmware

section as well so you just copy and

paste that line after doing obviously

the measuring the calibration stuff and

then you're good to go for rap firmware

one other thing we've changed in the

calculator is for the marlin

configuration or marlin firmware sku

adjustment kind of stuff

previously it was a single command that

you'd have to make sure is in the

firmware with sku correction obviously

being enabled but there seemed to be a

bug in that calculation somewhere not

exactly sure what was causing it it

wasn't very big it was only minor but it

was preventing some people in some

circumstances being able to correct

their skew sufficiently

so

i've changed it over to an alternative

skew method

and

that should help reduce errors as

there's less calculation actually going

on and it's closer to what the

measurements are that you're actually

getting off of the print

the second thing about marlin firmware

configuration is that it's nice to do

via gcode because recompiling firmware

is obviously a bit of a pain especially

with marlin so what i've done is

implement

into the calculator an m852 command

which you can copy and paste into marlin

send to your printer whatever

and that will configure the sku in that

way the downside is most printers don't

have sku correction enabled in the

firmware so you can't issue this command

because it doesn't understand the

command until you've enabled skew that's

my understanding so while the m852

command is there you may not be able to

use it without adjusting the firmware

anyway in which case you might as well

just implement the skew results directly

into the volume the next change is a

minor thing to the actual stl itself so

on the very outside there are some

chamfers and for some people this was

causing measurement errors depending on

where you measure it so those are just

going to be changed to a rounded phillip

and that should prevent this problem

where we've got a slightly sharp corner

with a chamfer you probably don't need

to do it again if you've already used

this file but for those that are going

to be getting it from now on you'll find

that it has fillets on the corners

instead of chamfers the next change is

not actually specifically to the

calculator itself although it's entirely

to the calculator itself so initially i

made it in microsoft excel just because

it's an application that i've always had

always used got it for business all this

kind of stuff so i was kind of a bit

close-minded there with what other

people are going to be using so now i've

got a libreoffice version which is an

open source

office suite

specifically the spreadsheet style

version so you don't have to worry about

converting it into formats and getting

errors and stuff there's just a open

document format for the calculator one

slight correction that i need to make on

my original video is that i said you

could do iteration specifically with

skew and that doesn't really work with

this

calculator in its current state it's

technically possible knowing the

pre-skew and after skew and you know

you'd be able to work it out but for

this it's just a single step before and

you're after

i have found though that you actually

don't really need to do any iteration a

single run of this calculation should be

enough to get you exactly as far as you

need to go

even if you're quite a long way out to

begin with as long as your measurements

are reasonably accurate you should be

fine one maybe negative thing is in

terms of the downloadable kind of set of

files that i have online i'm going to be

changing it to just have the calibration

the cauliflower and the files which i'm

charging for now you'd just be getting

this and the calculator before i had my

bridging and overhang tests i've not

really published any documentation on

how to use them i think very few people

were actually using them and not really

using them very effectively so i'll move

those out of this file set and we'll

just focus on this being the califlower

i think the value is still there and

from everyone that i've talked to that's

used this i think they would probably

agree so

again maybe you can perceive it as a

slightly negative thing but at the end

of the day they weren't really being

used very optimally anyway so that's

kind of it for the updates and stuff it

does continuously improve this has not

just been a single

bosch update it's been kind of updating

every few weeks or so pretty much since

it was created

just kind of as i get feedback from

users and their specific use cases

and so this is where we're at now i

thought it'd be good timing to do an

update on all the things that we've

improved

now onto some tips and tricks and how to

read the results so what i want to do is

run through

how

you could use this calculator to do what

you need to do

and how i've seen some people maybe

misinterpret things or

just read it slightly differently to

what i intended so

these are probably mistakes based on my

like written or format or whatever so

i'm just going to kind of run through

now so firstly the scale you don't need

to change the scale but if you have a

particularly large printer and you

really want to do it at a larger scale

you can it is technically better to do

it at a larger scale but the 100

millimeter size fits pretty much every

consumer printer and is pretty much good

enough as far as i can see so i wouldn't

worry about changing that don't panic

that you can't go bigger or smaller or

larger or whatever

generally stick with 100 unless you

really feel that you want something

different

in terms of the conditional formatting

that i've input you can see these are

all green which means less than one

millimeter of deviation in measurement

this doesn't mean that your printer is

really well calibrated and you're good

to go what it means is

when you took the measurement with the

caliper that my calculator thinks you

probably measured the right thing

for example if the calculator was asking

you to do an internal measurement and

you did an external one it would show up

in a different color and go i think

you've probably measured the wrong thing

so it's an interpretation of the

measuring that you've been doing not of

the quality of the print

in terms of error you should be able to

get within 0.1 or 0.15 millimeters but

this is dependent on your printer this

is kind of the point of doing

calibration right

if you can calibrate to a really precise

and accurate final result then you've

got a pretty good printer if despite

your best efforts it's still not very

accurate that indicates that there's

something wrong with the printer so for

example if you're doing measurements

you've done your before you've done your

after and the best you can get is still

within like one percent so you're like

plus or minus a millimeter

it indicates that maybe your walls are

like extra thick so

what this calculator is really doing

is not just doing the very outside and

very inside it's kind of trying to work

out where the actual nozzle moved where

the middle of one of those lines is

and that's important because it means if

your line is extra wide or extra narrow

the middle is still in the same place

one way that the calculator can indicate

that to you is what we've called or what

i've called the inner and outer

dimensions or results so the inner and

outer are a representation of the

average of your inner results and

average of the outer results so as long

internal dimensions and external

dimensions

if your on average internal dimensions

are too large and your external

dimensions are too small it means your

line width is probably a little bit too

narrow

likewise on the opposite if your inner

dimensions are smaller and your external

dimensions are a little bit larger it

probably means that your line width is a

little bit too wide

now

this is not it's a little bit imprecise

and not totally reliable but it can be a

kind of handy indicator especially at

the end you should find that they are

approximately the same the inner and

outer error should be the same because

that's kind of what the calculator is

trying to do it can't make your printer

better than it is but it can make it the

best it can be with what it's provided

so instead of your results being all too

large or all too small it just makes

sure that that line is in the right

place or in as close as possible to the

place it's trying to put it

so hopefully that makes sense it's a bit

of an interpretation skill to make sure

you're understanding the outcome of the

results

the other thing i want to mention is

skew so skew is measured in degrees it's

an angle

so

one thing that maybe gets missed with

angles is they don't change with scale

so

for example what's a good example

i don't know i don't have one near me

but if you have an angle like this

on a triangle for example and you make

that triangle 10 times the size

the angle or skew error is not 10 times

larger that's one of the like special

properties of angles versus linear

dimensions

the skew will be the same regardless of

the size of the print

the thing that can change is if you have

a printer that's skewed sort of so if

you can imagine like a square like this

being like perpendicular perfect angles

if it's skewed like this it kind of

becomes a parallelogram if you're

printing in that shape that also gets

skewed in the same way if you then

rotate that shape and printed it in a

different way it would be skewed in a

slightly different way so if you have

two shapes that should be perfectly

square printed slightly differently in

terms of orientation on the bed they

will represent slightly different skew

in slightly different weird ways for

people using prusa slicer and cura two

very common slices actually

it's a slight downside of those slices

that they don't have a percentage

adjustment for size

so with different materials you get

different amounts of thermal expansion

so it's very used to have it's very

useful

to have a percentage adjustment because

the amount of shrinkage is related to

the size hopefully we get those soon but

at the moment they don't have that

compensation method available so you'll

need to use steps per minute steps per

millimeter in the firmware to get as

close as possible and then you might

have to do kind of adjust the size of

the part in the slicer kind of annoying

but unfortunately that's the work around

for project slicer or cura which don't

have percentage compensation one thing i

didn't mention in the previous video as

well is that some printers don't really

need this calibration it's not because

they're perfect is because they have an

inbuilt calibration method

there's not many but one is the prusa i3

mark 3 s plus whatever

this printers that look like this

so

while they have that built-in

calibration it can be useful to have a

print just to kind of validate that it's

done the right thing so you can still

get it print it and measure it and then

you'll get a result for the skew to

check that it is as accurate as you want

it to be but generally

for the prussian mark iii

don't get it in the intention of using

this to calibrate use the in-built

system

the other printer that it doesn't work

particularly well on is the pressure

mini

strangely because there is no firmware

calibration methods for doing skew

adjustment on that printer the only way

to adjust sku on the prusa mini is to

like physically assemble it slightly

differently

which is not great i'd much rather

there's a basic skew feature especially

as it's a printer that's like supposedly

for like mass manufacture

not quite mass manufactured but you know

what i mean i like a print farm printer

but if you can't calibrate it to be the

right size and skew

all the parts are going to be a little

bit

wonky so not ideal but there you go

so of course once you've printed one of

these maybe you printed one for a few of

your different printers you're going to

have a few cauliflowers sitting around

what do you do with them obviously you

could throw them out or whatever but a

lot of people are using them as coasters

for like mugs of

tea coffee whatever and that's a really

great use i think they seem to be about

the right size they're nice and flat

very easy to use

lovely tea coasters so there we go

that's it for me today just a few

updates on the cauliflower

you can get it in the link in the

description thank you very much for

watching and i'll see you in the next

one
