The printer is homing at the beginning.

;DUET2 start-code
G90               ; Set to Absolute Positioning
M82               ; Set extruder to absolute mode
G21               ; Metric values
G28

M915 X Y S5 R3 
M117 Printing...

In which line i turn it off?

@dc42
I have an cartesian printer supplied by 24v with 2A 9kg/cm motors. But it seems that the duet will not recognise losing steps while printing. No matter in which situation (fast or low). Is it really enabled ? the last line in start code is M915 X Y S5 R3

Hi,

there is an problem with Stall detection while printing however sensorless homing works fine while homing.
Is it right to define the motor stall detection in start g-code or at the end of config-file.

Until now it is at the end of my start gcode (and in config.g)
start-gcode from cura:

M574 X2 Y1 S3
M915 X Y S5 R3

has someone compiled it with this settings successfully ?

Thanks mr. dc42 for your fast feedback.

I think there is something really wrong with my compiling settings in eclipse:

and of course there is an objcopy in GNU Tool ARm folder but not on github.
What should i do ?

Okay i have compiled the firmware but the result data are no .bin File.
How can i make the .bin file ?

compiled Files:

gcc builder is active

@dc42 said in Y baby step insted of Z baby step on display:

White Knight

Yes, its the same System like White Knight 3D-Printer.

I Think i have found it in sourcefile UserInterface.cpp

I will try to compile it and let you know later if it has worked

Hello,

is there an option to chance the axis in the macro ("z baby step") on LCD.

I use a complete different System for my movements.
My Z controlls an belt any my X and Y prints on an angle on the Z Belt. So Y would be my Z and the height of an object while printing.

Thanks and best regards,
Ben

Hi,

i try to setup sensorless Homing on X and Y but it does not work in negativ homing direction. If i change the homing direction (+) it works fine for X but not four my two Motors on Y an i need Homing in 0 .

Driver Mapping:
X on Driver 0
Y1 on driver 1
Y2 on driver 4

I remapped the Drivers in config.g:
; * Motor remapping for dual Y
M584 X0 Y1:4 Z2 E3

and tested it with the following macro:
For X: STALL - X.g
For Y: STALL - Y.g

Whats wrong ?
