Hello guys,
i bought very cheap Duet board but i cannot find any documentation for this. Is someone familiar with this board? do you guys have manual for it? thank you.

@t3p3tony I heat it up to 195C, measure 11cm, extruded 10cm with G1 E100 F60 and measure the rest and calculate. It extrudes perfect amount and keep 1CM. I think the e-steps are ok. I will try disable the bed compensation and let you know. thanks

@oliof I am living in Shenzhen (I am not chinese), China and i saw this board in the used electronic store - it cost $10 CAD. So i was wondering if is somehow usable - I have two Vorons 2.4 and one Creality CR6-SE printer. I am planing to build one more printer so i was thinking to use this board with reprap to just see what it can do

@fcwilt Thanks for the bed.g example - it works nicely

Hey guys, thanks for the help - I am finally printing

I have one more thing that bothers me. CURA
it prints the first 4 bottom and top 4 layers (solid ones) in proper speed, but areas where is just walls and infill are terrible slow. all my speeds in the Cura are set way higher, but the print is slow. Maybe someone had same issue before and know the solution. I also tried Simplify3D with same results.

My G-code flavor is Reprap
My Cura start code is

M140 S50
M190 S50
M116
G28
M400
T0 ; Select the tool
G29 S1 ; Load Mesh coordinates
M82 ; Absolute extrusion mode
M140 S{material_bed_temperature_layer_0}  ;Start heating bed
M190 S{material_bed_temperature_layer_0}  ;Wait for bed to reach temp before proceeding
M104 S{material_print_temperature_layer_0} ;Start heating extruder
M109 S{material_print_temperature_layer_0} ;Wait for extruder to reach temp before proceeding
M98 P/sys/start_print.g

thanks for your time

Hello guys,

@t3p3tony no, the endstops become not activated. they work after reboot but when the motors make motion they become not active, i don't know why. but Klipper have no issue - in klipper i have to just add pin numbers and works but RR doesnt react properly on xstop, ystop etc. also i tried to change to other sockets without luck.

Thanks @T3P3Tony and @fcwilt
i switched all those motors correctly by it really didn't help me with ENDSTOPs
. So i went back to Klipper and they all work fine, weird. I cannot firuge out RR.

I have another question maybe that is the issue -

from top view my origin 0.0 position is in rear, right corner. In klipper i have same origin. In klipper my movement to left are positive so for example if i go from 0 to 200, it is + direction. Here is the minus direction so it will be -200. is that correct or i have switched motor directions?

|-----------| 0.0
|.............|
|.............|
|.............|
|________|

When i was installing Klipper i have to switch Z motors position so they are like this

Z3 |-----------| Z
      |.............|
      |.............|
      |.............|
Z2 |________| Z1

In the REPRAP the motors are defined with M584

M584 X0 Y1 Z2:5:6:4 E3

does the Z order matters?

@t3p3tony so i tried to downgrade, it was still with the same issue. I also have one SD card with configured klipper, so i tried to flash klipper and klipper works fine. But i want to use reprap fw.

; homez.g
; called to home the Z axis

G90 					; absolute mode
G1 H2 Z40 F3000   		; lift Z relative to current position
G1 X310 Y345 F7000		; go to enprobe point
G1 H1 Z-340 F1000  		; move Z down stopping at the endstop
G1 H2 Z5 F1000 			; move Z back 5mm
G1 H1 Z-10 F1000 		; move Z slowly towards the switch until it triggers
G1 H2 Z50 F3000			; move Z up 50mm
G1 X175 Y175 F7000		; go to the center of bed
G90 					; back to absolute mode

@t3p3tony 3.4.0beta4, ok so i think found the issue - when the homing goes direction Z it disable all endstops. Did you guys see this issue before?

I updated fw to 3.4.0beta5 and my endstops stop working. when i want to home any direction it doesn't stop the motion in that specific direction. I tried the gcode M119 and i get this:

M119
Endstops - X: not stopped, Y: not stopped, Z: no endstop, Z probe: not stopped

when i hold the switch in any direction and shoot the same gcode, it sends me same response. I dont know where is the problem? should i reset the board and flash the older fw?
