Cannot check stepper X and Y

[wraith harbor]

hello, starting the first electronic check on my build. Stepper on all z axes are fine, but if I test X or Y stepper, I'm getting a firmware shutdown. In the log I can see this :
Received 174.775626: b'{"id": 547771047168, "method": "gcode/script", "params": {"script": "STEPPER_BUZZ STEPPER=stepper_x"}}' gcode state: absolute_coord=True absolute_extrude=True base_position=[0.0, 0.0, 0.0, 0.0] last_position=[0.0, 0.0, 0.0, 0.0] homing_position=[0.0, 0.0, 0.0, 0.0] speed_factor=0.016666666666666666 extrude_factor=1.0 speed=25.0 Reactor garbage collection: (169.670886991, 0.0, 0.0) Unable to read tmc uart 'stepper_x' register IFCNT
I'm using TMC 2209 and hardware wiring are the same for Z, X and Y axes. What should cause this ?

Stepper_X config for example :
`[stepper_x]

Connected to X-MOT (B Motor)

step_pin: PE11
dir_pin: !PE10
enable_pin: !PE9
rotation_distance: 40
microsteps: 16
full_steps_per_rotation:200 #set to 400 for 0.9 degree stepper
endstop_pin: EBBCan: gpio24
position_min: 0
position_endstop: 350
position_max: 350

##--------------------------------------------------------------------
homing_speed: 25 #Max 100
homing_retract_dist: 5
homing_positive_dir: true

Make sure to update below for your relevant driver (2208 or 2209)

[tmc2209 stepper_x]
uart_pin: PE7
interpolate: True
run_current: 0.7
hold_current: 0.4
sense_resistor: 0.110
stealthchop_threshold: 0`

by the way, board is a spider 3.0

Unable to read tmc uart 'stepper_x' register IFCNT is usually caused by:

• missing or incorrectly installed stepper driver
• missing or incorrectly installed stepper driver jumpers
• no power to the stepper driver
• incorrect configuration

now, i have no experience with spider 3.0, and their documentation appears to be lacking...

[wraith harbor]

I've shutdown the printer for tonight, but I will recheck you point tomorrow

[wraith harbor]

in fact, there is a jumper plug for powering M0 and M1. It can be 24V or 48V but by default, there is no jumper so no power 🙂 I've installed the provided jumper to connect 24V and it's fine now.

[wraith harbor]

now I have a problem with my Y stop. it's allways triggered. I've measured with a continuity tools. by default, circuit is close and if I close the microswitch, then the circuit is open. endstop is configured as follow in stepperY :
endstop_pin: ^PB13

which is connected between PIN PB13 and pin 3V3

[severe basalt]

endstops shoudn't be connected to voltage, connect to PB13 and GND

[wraith harbor]

oh.. so spider schema is wrong !

perfect ! ty

next question 🙂 before doing the probe_calibrate (I have a TAP), should I do a QGL before ?

[severe basalt]

yes, do a qgl and then home z, also do a qgl and bed mesh before every print

[wraith harbor]

ok i see also that I've set my safe_z_home to home_xy to 150,150, but noise is not in the middle it's more 200x200 (my bed is 350, I know I need to change to 175)

[wraith harbor]

It seems I have problem with Z2 it's making horrible noise and is not moving as the other. If I do a STEPPER_BUZZ STEPPER=stepper_z2 it's moving but with high noze.

of course now that I have my smartphone to record the noze, it's gone

can you point me on how to do a bed mesh. QGL is now fine

Oh by the way, I've installed the BTT CAN SB2209 in my hotend

[severe basalt]

see the voron docs for instructions

[wraith harbor]

meshing in progress 🙂

Soon another 2.4 will born !

I think I need to do some adjustment no ? but I don't understand how. I've checked my bed with a physical level and it's flat. Does it mean that the problem is more with Z motor ?

forgot my question, I've made a QGL and now bed is like this.

Shall I need to QGL every time I turn on my voron ? or every time I'm starting a print ?

[severe basalt]

i do this before each print in this order:

• home all
• qgl
• home z
• bed mesh

[wraith harbor]

ok thank you, I will so adapt my gstart macro

by chance, do you already seen this error :
Heater extruder not heating at expected rate Transition to shutdown state: Heater extruder not heating at expected rate
I was doing a PID_calibrate on the hotend

[severe basalt]

the recommended start macro is a better print start macro

[severe basalt]

what hotend thermistor do you have? and where is it connected to?

[wraith harbor]

I don't know hotend model. it was delivered with my Tz-v6. It's connected to SB2209

thru canbus

[severe basalt]

we need to know which port it's connected to on the sb2209

[wraith harbor]

sensor_pin: EBBCan:gpio27

sensor_type: Generic 3950

[severe basalt]

and it's actually plugged into that port on the sb2209?

[wraith harbor]

yes it is. I can read value as hotend is heating

[severe basalt]

did the graph in mainsail/fluidd show the temperature rising before klipper shutdown?

[wraith harbor]

yes

[severe basalt]

what temperature were you trying to pid at?

[wraith harbor]

245

I've rerun a pid calibrate and it was fine now

it is clearly not the same graph as before

[severe basalt]

huh, that's odd that it's now working, but the graph looks good 👍🏼

[wraith harbor]

yes it's on the good way. Now I need to print some missing part so little break in the build 😦

thank you for all help

shall I a last question : I'm printing panel mount part. I'm using 3mm glass, but for corner support there is only 4 and 6mm as for midspan. shall I print 4mm ?

[severe basalt]

you want 3mm glass + thickness of foam tape

[wraith harbor]

ok so 4mm should be fine tx
