on my 2.4R I am trying t make sensorless homing.
I have followed the voron manual, but still have issues.
I am trying to make senosrless homing work.
I have made the following discovery.
When homing x and y the aboslut x and Y on the toolhead klipper screen gives -150 for just a moment, and then 300
The toolhead doesnt mode at all, what can cause this ?
It is set up accoring to both voron manual and a youtube step by step. Also I have the same printer.cfg as another member where there is no problem
I can make X/Y move app. 2 cm then it stops.- it appears to be the pull away from end.
G28 doesn't move anything
In the console it writes Run Current: 1.09A Hold Current: 1.09A 3 times for x, and the same for Y
My Y section looks like this :
[stepper_y]
step_pin: PG0
dir_pin: PG1
enable_pin: !PF15
rotation_distance: 40
microsteps: 32
full_steps_per_rotation:200 #set to 400 for 0.9 degree stepper
endstop_pin: tmc2209_stepper_y:virtual_endstop # PG9
position_min: 0
##--------------------------------------------------------------------
## Uncomment for 300mm build
position_endstop: 300
position_max: 300
##--------------------------------------------------------------------
homing_speed: 40 #Max 100
homing_retract_dist: 0 # 5
homing_positive_dir: true
## Make sure to update below for your relevant driver (2208 or 2209)
[tmc2209 stepper_y]
uart_pin: PD11
interpolate: false
run_current: 1.1 # max 1.2
#hold_current: 0.5 # *********ekstra
sense_resistor: 0.110
stealthchop_threshold: 400
Diag_pin : PG9
driver_sgthrs : 75 # 255 most sensitive 0 is least sensitive
What can I do ?
SOLVED. Found that I have the tic 2225 which doesn't support this function - replaced to tmc2109 and it works
