I really like this guide on how to tune your steppermotors. Working it through (and the excel spreadsheet) gives a good idea how everything works together.

sense resistor is one of the factors which determine peak A for the motor. Together with the Current Scale setting,

chamber_filter

Ah, now I understand. 👍 Awesome explanation for me. I wanted it to change dynamically (0.2 during print, 1.0 after the print. But.... As you explained the filter can't be the problem for my warping. So I'll do a search for where the air escapes. 'cause Recirculating air through the filter is what I'm aiming for. Thank you very much!!

chamber_filter

thank you!
but I don't know how to get this to work aside the chamber_filter macro... Would it work if I put something like this in the Orcca slicer at "Machine end G-code" beneeth "END_PRINT"? SET_GCODE_VARIABLE MACRO=RatOS VARIABLE=variable_chamber_filter_speed VALUE=1

And that was exactly the one I used… until yesterday where the Motor died. Searching for a possible cause I found the sense resistor problem. But I believe there was something going on with it before. 🤷🏼‍♂️ No I‘m using the moon’s CSE14HRA1L410A-02 motor. Seems much better regarding heat.

@MDFPereira in RatOS.cfg stands the following:

#------------------------------------------------- EXTRUDER -------------------------------------------------
# The extruder motor used for pushing filament through the toolhead
# Connected to Nitehawk 36
# Driver: LDO TMC2209
# Motor: Generic Stepper
# Voltage: 24
#------------------------------------------------------------------------------------------------------------
[tmc2209 extruder]
stealthchop_threshold: 0
interpolate: False
uart_pin: toolboard_t0:gpio0
run_current: 0.35
sense_resistor: 0.11

[extruder]

@MDFPereira @miklschmidt It Works!!!! I once again erased the folder and now took the files from here: https://github.com/3dprintpt/RatOS-configuration/tree/development/boards/ldo-nitehawk-36 not from the PR. (I thought the files are the same, ...?) Thank you so much MDFPereira and miklschmidt!

@MDFPereira I just tired to flash the nitehawk but it still fails. Is this as it stand for now the expacted behaviour? Or is there something I do wrong? Here my output when I trigger flashing all boards from the "Help" button in the configuration Dashboard.

so: 1. I deleted the old ldo-nitehawk-36 folder 2. extracted the rar archiev on my windows machine and copied all files to my printer 3. checked the permitions and did a
