DWC Z - Axis Movement off by Factor 10

Frederik

according to the BOM:

8mm Metric ACME Lead Screw

BoA

@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.

Frederik

Veti

thats a 4 start tr8 leadscrew

it has an 8mm pitch

BoA

@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?

Frederik

thanks a lot, i will try the new values

BoA

@Frederik And cleanup You config. Seems

is duplicated

Frederik

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

Frederik

@BoA oh, i see, thats a copy and paste error.... in my config its only once

BoA

@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

@BoA so only this line :

M591 D0 P5 P"io3.in" R40:120 E3.0 S1

the green light flashes constantly and when i move the filament i respnds with faster blinking.

is this all i need ? no extra pause and resume command ?

BoA

@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

Frederik

@BoA my extruder Setup:

Original Bondtech BMG with a E3d Volcano with 0.4 mm micro swiss nozzle and titan heatbreak. 40W Heater and Thermistor 100K
0.9° Pancake Stepper

bedheater: 220V AC1.2 kW Keenovo Silicone Pad 400x400

Frederik

@BoA said in DWC Z - Axis Movement off by Factor 10:

M591 D0

Response: Extruder 0 has no Filament Sensor

BoA

@Frederik BMG with 0.9 stepper + 16 microsteps should have 830steps/mm

Frederik

i will try it. on moment

BoA

@Frederik Paste Your config.g only and result of

M98 P"config.g"

wow, i dont know why its doubling these lines ?!?
