@jay_s_uk yes, it will be a custom firmware for the esp32 on the knomi but I think it won't be to complicated (I've made some other project with esp32 using ble).
My biggest concern is how to get the data I need trough the panel due pin.

is it possible to use the knomi with the duet? It is a round screen designed for the voron and klipper compatible.
I've noticed that it is powered by an esp32.
If I'm not wrong I can connect an esp32 to the duet bord (the panel due pin urxd0 and utxde0 3.3v and gnd) to keep some info such as temperature and print time, and using Bluetooth I can connect to the knomi with a custom firmware for it that read the Bluetooth info and then update the screen.
Do you think it is possible?

thanks a lot!!!
i learned something new!

Hi,
I have a corexy printer with standard 1.8° nema stepper with M350 X16 Y16 Z16 E16 I1 in config.g

Question 1:
I am confused about the M350 value...
I have the M350 with "I1" so the interpolation is enabled and i'm using a microstepping of x256 with interpolation.
I'm right? or i'm actually using full step interpolated to x16?

Question 2:
Is there any sense to change my M350 with

M350 X16 Y16 E16 I1
M350 Z1 I0

I have two T8x4 screw for Z so the printer has a magic number of 0.02mm
If in my slicing SW i set a layer height of 0.1 or 0.2 i can reache them with 5 or 10 full step.
Is there a good reason to use the interpolation of x16 (or x256) microstepping instead of using a full step for the Z axis?

Question 3:
in my config.g file i have the M92 X80 Y80 Z800 after the M350...i have to change my M92 value if i change M350 value?

thanks in advance

Hello,
i want to know if is it possible to change the 0.05mm value of the default baby step to another value.
My printer has a magic number of 0.02mm so if i baby step with 0.05 my Z motor aren't in a full step position.
I already know that i can use M290 S0.02 on Gcode console but is not fast as using the button on the DuetWebServer.
thanks in advance

I forgot to ask if the laser can also be controlled by the duet wifi board (in addition to the bltouch and servo) without the use of an expansion board.
Maybe using:

• Bed haeter (i don't have it) for laser
• Heater7/PWM5 for servo
• Heater1 beacause (i have only one hotend) for BLtouch

thanks, as soon as i have the connection scheme i'll ask for a feedback

Is it possible to use a bltouch for z probe and adding another servo to unused pin?
I want to design a changing tool and want to use a servo for a locking device.
I have a duet wifi without expansion board or paneldue.
Thanks in advance

or a simply copy & paste from the default windows image viewer.

@lakko said in Nonlinear extrusion tweaking:

M592 D0 A-0.01096 B0.00591 L0.021

based on the results is the M592 correct?
