DWC Z - Axis Movement off by Factor 10
-
Hello together,
I just finished my very first 3d Printer build.
Its a 400x400x400 CoreXY Kit from Ratrig.it´s running a duet 3 board with a Raspberry 3b+ with the original SD Image from Duet.
I Updated the Reprap Firmware to 3.1.1 and got some Problems with the configuration.
I don´t know if it is in the right Category.
i want to configure the steps per mm, as I noticed that the steps in the DWC are off by the Factor of 10 for the Z-Axis movement.
I use 0.9° Stepper on X, Y, and E.
and at the moment 1.8° Stepper on the triple Z Spindel Motors (i will upgrade these to 0.9° Next Week )I used the Web Config Tool for my first Tests.
When I am measuring the movement distances, X, Y, and E are really spot on, but the Z Steps are off by Factor 10.when i drive 0.01mm -> it moves 0.1
when i drive 0.1mmm -y it moves 1mm
and so on....I used Standard M8 Spindles with I believe 1.25 Pitch
I started with 2560 Steps per mm with x16 Microstepping + interpolation.If i increase the steps to like 4500... it's not really a difference.
because it is my first build, I don't know what to do next to solve this problem. ;(
i also tried the individual z-axis bed leveling, but I don't know if it's funktioning working properly and using the actual measured values.
And my Last Problem:
How can I get the Duet Laser Filament Sensor to Pause the Print when it's detecting a Problem?
I only found in the duzoki the following line:
M591 D0 P5 C"e0_stop" R40:120 E3.0 S0 ; Duet3D laser sensor for extruder drive 0, connected to endstop input 3 (E0), tolerance 40 to 120%, 3mm comparison length, disabled
Thanks a lot in Advance
Regards

M92 X160.00 Y160.00 Z4079.68 E873.08 ; set steps per mmThis looks weird. What screws you have in Z ?
-
@BoA Standard M8 Spindles
-
the movement sections is in your config twice
M92 X160.00 Y160.00 Z2560.00 E837.02 ; set steps per mm
this line overwrites the first line for example.I used Standard M8 Spindles with I believe 1.25 Pitch
those are not standard. you really need to know
post the link the the product that you bought. -
@Frederik said in DWC Z - Axis Movement off by Factor 10:
Standard M8 Spindles
M8 Spindles have not been used in 3d printers for years because of bad results.
do you mean tr8 lead screw?
-
@Veti It was a complete Kit from Ratrig. There were no specifications other than M8 400mm
I will ask the manufacturer -
@Frederik Make a picture. will be faster.
-
according to the BOM:
8mm Metric ACME Lead Screw
-
@Frederik If this is Tr8x8 with 1.9deg stepper and 16microsteps it should be 400steps/mm
Also seems movement parameters section is doubled for some reason.
-
-
thats a 4 start tr8 leadscrew
it has an 8mm pitch
-
@Veti So as I wrote, 1.9deg, 16 microsteps, 8mm pitch - 400steps/mm. Not ~4000 or 2560.
And... what kind of extruder You have that E steps/mm are so.. not a round number?
-
thanks a lot, i will try the new values
-
@Frederik And cleanup You config. Seems

MY other question is about the LAser FIlament Sensor:
I only Found the following Line in the dozuki for RRF 3.x
M591 D0 P5 C"e0_stop" R40:120 E3.0 S0 ; Duet3D laser sensor for extruder drive 0, connected to endstop input 3 (E0), tolerance 40 to 120%, 3mm comparison length, disabled
would this work on my duet 3 (connected to io3)
M950 J3 C"!^io3.in" ; Input 3, inverted, pullup enabled
M591 D0 P5 C"io3.in" R40:120 E3.0 S1 ; Duet3D laser sensor for extruder drive 0, connected to IO 3,
tolerance 40 to 120%, 3mm comparison length, enabled -
@BoA oh, i see, thats a copy and paste error.... in my config its only once
-
@Frederik said in DWC Z - Axis Movement off by Factor 10:
M950 J3 C"!^io3.in" ; Input 3, inverted, pullup enabled
I would remove this one.
-
-
@Frederik Should be fine. But I am guessing when filament monitoring shows some problems pause.g is executed to pause the print.
You can check sensor status by M591 D0
