Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed

Describe your issue:

… my issue here is after swappiung board from BTT SKR mini 3v3 to this new one mellow FLY RRF Pro 3v3
Issue was my x was going oposite way where no endstop managed to get that sorted reading a tutorial here. But then i press home and the x slams to the endswitch and just grinds there.
Also confirmed with query_endstops all are showing open now so endstops are working fine checked them with pressing on them and they showed triggered
S toped the printer tried few thing wiuth no luck. when i do G28 X → both x and y moves at same time in config pins are not the same. Whn i do G28 Y → both move again x and y till grind.
I have no idea where to go from here. Thank you in advance for help

Just did the stepper_buzz and all is fine when buzzing x only x moves back and forward. When buzzing Y only Y go back and forward.
also i have verified bl touch and it works fine as well, I have no idea whats up.

My hammer is in stand by mode now!

The Ender 3 has cartesian kinematics, not corexy as you have in your config.

4

how do i change that? This board was direct replacement for ender 3 and the config file was written by company as well

5

I changed to cartesian i can home now but man is the board ever loud. Sound like printer or not silent driver or 8 bit

6

Loud or silent does not have to do with 8 or 32 bits.

What board do you use now exactly?

7

MCU / Printerboard: Fly-E3-Pro-v3 uses tmc2209

8

That is a 32 bit board with silent drivers.

[tmc2209 stepper_x]
uart_pin = PE4
run_current = 0.580
hold_current = 0.500
interpolate = False

[tmc2209 stepper_y]
uart_pin = PE0
run_current = 0.580
hold_current = 0.500
interpolate = False

[tmc2209 stepper_z]
uart_pin = PA8
run_current = 0.580
hold_current = 0.500
interpolate = False

[tmc2209 stepper_z1]
uart_pin = PC14
run_current = 0.580
hold_current = 0.500
stealthchop_threshold = 999999
interpolate = False

[tmc2209 extruder]
uart_pin = PD5
run_current = 0.580
hold_current = 0.500
interpolate = False

You should set interpolate to True

and

stealthchop_threshold = 999999

to all TMC drivers (Already wired that you have it on z1 but not on z)

9

yes did the ```
stealthchop_threshold = 999999 like 5 minutes ago and its quite now. What will the interpolate = False to true do to a printer can’t find a good explanation.
