Core XY - pulling my hair our.

Kiwi3D

Number of issues....

Running like a snail...only 10mms on X homing attempt
Sensor less homing is not working. When it get to 0 it hammers the carriage and then tries to do a Z drop . given it shared motors that makes sense I guess

Motors are 1.8 LDO motors

I have attached my config.g and homez.g

config (1).g homex.g

Any help appreciated please

@Kiwi3D is your steps/mm correct, move the x axis 20 mm does it move 20mm?

@Kiwi3D up your homing speed to F8000 ,

here is my x homing, your need to change out my motors numbers for yours

; homex.g
echo "home the X axis"
M400                                 ; make sure everything has stopped before we make changes

@moth4017
You're Core XY too?

moth4017

@Kiwi3D im core XY , , you are core Xz
but you should still be able to use my home x , you need to modify it for your core XZ

something like this

; homex.g
echo "home the X axis"
M400                                 ; make sure everything has stopped before we make changes
G91                                  ; relative positioning
M915 P0.0 S5 H200 F0 R0              ; Configure Stall Detection
M906 X550                            ; set homing motor current
G1 F8000
G1 H1 X-350                          ; Home X-Axis independently
M906 X1000               	     ; set homing motor current
M915 P0.0 S35 H500 F0 R1             ; Configure Stall Detection
M400                                 ; make sure everything has stopped before we make changes
