Are jumpers needed on the drivers themselves?

Yes, that's the way mine are configured.

As for you printer.cfg...

This is my Stepper X section. Beware... I might not be using the same connection on the Super8 Pro because I had wired mine per the old instruction that had the motors flipped and I had to correct it in the printer.cfg

All of the [tmc5160 stepper ?] sections are the same for all four except for the "cs_pin:" values

My printer.cfg tmc5160 pretty much reflect yours.

The stepper setting reflect my motor configuration.

None of the stepper motor function when buzzed.

The tmc2209 on Z returns:

Unable to read tmc uart 'stepper_z' register IFCNT

The tmc5160 on X returns:

 

Unable to write tmc spi 'stepper_x' register GLOBALSCALER

The klippy log file relating to the steppers has this:

TMC stepper_x failed to init: Unable to write tmc spi 'stepper_x' register GLOBALSCALER
TMC stepper_x1 failed to init: Unable to write tmc spi 'stepper_x1' register GLOBALSCALER
TMC stepper_y failed to init: Unable to write tmc spi 'stepper_y' register GLOBALSCALER

TMC stepper_z failed to init: Unable to read tmc uart 'stepper_z' register IFCNT
TMC extruder failed to init: Unable to read tmc uart 'extruder' register IFCNT

(I've attached the full klippy.log and my printer.cfg)

As it's common across all steppers my gut feeling is that it is a communication problem. Other than reflashing everything again I am stuck here.

From what I can remember - there is a conflict with the Max31865 chip. Mine was the display on the Octopus board.

Here is the thread I followed and saved:. Cannot find the actual link - has been some time ago.

Octopus Pro SPI fix:
I can confirm the shared spi is working, I do have BTT Octopus Pro with TMC5160Pro and Fysctec mini12864 connected.
At first after the mcu update, it didn't work (unable to write tmc spi 'stepper_x' register globalscaler).
I don't use the MAX31865 so when I added those two lines:

[static_digital_output disable_max31865]
pins: !PF8
It worked.

OK, so after buying a third 5160 driver and inserting it … it didn’t work.


But I found someone who was having problems getting their ez31865 to work and they had fixed it with a static output just on the sd card slot pin.
I tried that and the thing worked.
I then slotted in the two original 5160 drivers and they worked too.
I can’t believe it but we were on the right track, just narrowly missing it.

[static_digital_output my_output_pins]
pins:!PB12

A stupid exclamation point was all that stopped it working before with the static output suggested by jjarosz. I didn’t think to try that with it at the time.
Thankyou again everyone for helping.

Looks like it's from February 2022 but the GitHub issue is missing the latter half of the text you saved.

[TitusADuxass]

Interesting.

I have no MAX31865 in my printer.cfg

Those are some really strange errors. Not the kind you normally fix in the printer.cfg. I'm a mechanical guy with a little electrical knowledge but, this looks to me like a possible power issue. I would double / triple check the power wiring. On the Super 8 pro you need to connect all of the power connections along the bottom of the board like mine. You also need to have a common neutral wire running between both power supplies and watch out for the bed power on the left, the polarity is opposite of all the others. I had an issue where my steppers wouldn't buzz and I went back over my wiring and yup, forgot to tie the two PSU's together with a neutral wire.

Watch out for this guy...

You nailed it!

Numb nuts here forgot to feed 24v to the Drive Power.

Some Eagle eye on discord saw it straight away.

@TitusADuxass most of my printer problems are from dumb mistakes it reminds me of math class. Always one or two dumb mistakes killing my A grade. 

[TitusADuxass]

Right!

First thing this morning is to check all the wiring - the fact that I complete missed wiring 24v to the driver side of the board rocked me. So I've got a litre of Earl Gray  and some relaxing classical music on low, the moggies are sleeping off their breakfast so I should be undisturbed for a couple of hours.

 

[TitusADuxass]

It works when you connect the power to board.

X & Y are going in the incorrect directions. I remember how much fun I had at this stage with the v2.4 and that only has 2 motors.

Edited June 2, 2024 by TitusADuxass

[TitusADuxass]

Well that went quicker and easier than I expected.

She homes - 

 

[TitusADuxass]

One dodgy tmc2209 identified and swapped out - extruder now working.

[TitusADuxass]

Bed Heater PID calibration in 8 minutes (from 22c to 100c).

That's some heater.

[TitusADuxass]

Nice lines.

[Penatr8tor]

How about that! Congrats @TitusADuxass!

I added the classic extra bump on homing and a return to the center of the bed for my Z home.

Just add this to your [stepper_?] X and Y sections

homing_retract_dist: 5.0
second_homing_speed: 25

FWIW and your mileage may vary... I have my printing limits set as X=330 and Y=300. Moving all the way back to 330 really scrunches things up against the back of the printer. I have found 300 on the Y to be a good safe distance. My bed center is X=165, Y=150.

Another important thing to note is that, if you installed the screws in the back of the build plate to locate the PEI sheet... there will be a couple of M3 threads sticking up above the PEI sheet. If the screws you used are too long, they can potentially contact your beacon probe and if it does... you will not have a good day. Make sure that if you do install the screws as PEI sheet locator pins that they only stick up 1mm or so above the build plate, any more could be catastrophic.

[Penatr8tor]

@TitusADuxass

You need to spin your PEI build plate around 180 degrees. Small tabs in back, big ones up front.

I got mine to home in the bed centre with this:

[safe_z_home]
##    XY Location of the Z Endstop Switch
##    Update -10,-10 to the XY coordinates of your endstop pin 
##    (such as 157,305) after going through Z Endstop Pin
##    Location Definition step.
home_xy_position:165,150
speed:100
z_hop:10

I agree with you about max Y,  in my .cfg it was already limited to 315 but I tweaked it down to 310.

I haven't installed the PEI location screws.

I have got to sort out the extruder settings, mine thinks that filament costs nothing. It's whipping through 230mm when I ask for 50mm.

I encountered some confusing stuff with my extruder. I eventually had to count gear teeth to confirm that I had the correct ratio. Just so you know... Motor is 10T and Extruder Gear is 50T. Microsteps is 16, full steps is 200. Try using my rotation distance as it will be very close to what you'll calculate with these settings.

Below is my extruder section, just double check the pins, mine might use a different port on the controller. I left the original values on the same line and commented them out like the uart_pin:

Yeah, better safe than sorry. I would go to 315 but with the Beacon hanging under the print head I will err on the side of caution.

The PEI locator screws are nice to have mine are M3 x 12mm and only poke about ~1.5mm above the PEI sheet.

Also... here's my temp section in case you want to monitor more than just your hotend and bed.

[temperature_sensor FLY-Super8]
sensor_type: temperature_mcu

[temperature_sensor raspberry_pi]
sensor_type: temperature_host
min_temp: 10
max_temp: 100

and lastly... I don't know if you've used this before but you can combine pins in the printer.cfg. For example... If you have multiple fans or LEDs that that you want to control together you can use the following.

Fans:

[multi_pin RSCS_Pins]
pins: PD12, PB10

[fan_generic RSCS]
##  RSCS Fans - In FAN7 Positon
pin: multi_pin:RSCS_Pins
max_power: 1
shutdown_speed: 0
kick_start_time: 0.1
off_below: 0.10

LEDs:

[multi_pin LED_Pins]
pins: PA2, PA3

[output_pin LED]
#In FAN2 position if 12 or 5V
#When 24V use a heater pin like Heat4 PF6
pin: multi_pin:LED_Pins
pwm: false
value: 0.5
shutdown_value:1
### gcode command: SET_PIN PIN=LED value=0 to 1

Yes, the preconfig printer.cfg tries to cover all possiblities, I was chasing my tail for a bit.

Got it nailed down to 19.768

Yup, if you're in the ~20mm range your good. Anything way outside of that and you're probably off track.

Thanks - learned something new today - implemented this on Caselights of V2 and RSCS Fans on VZBot

[TitusADuxass]

Aaargh!!

I've just installed the screen and then the screen related stuff via Kiauh.

It's hung the Pi, now I cannot SSH nor can I get to the printer via mainsail.

 

[Penatr8tor]

I assume you power cycled and are still getting that error. Check for dumb mistakes, that's where I usually find solutions. Hopefully your SD card didn't get corrupted.

I gifted my Switchwire to my nephew this past Christmas. I had to remove the SD card and modify the supplicant file via sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

The I pulled the SD card out of the reader instead of pulling the reader out of the USB and corrupted everything. I spent 2 days recreating everything from scratch. Believe it or not I was able to get everything reconfigured and running in a couple of hours, even the servo arm klicky probe.

[TitusADuxass]

I checked that the 2 USB out were in and the USB in was in.

I then disconnected the display.

Still no joy, 

The display was showing live temperature data and the CPAP cycles on power up.

But it's not showing up in my router. Fortunately I downloaded the cfg files just before I started working on the extruder.
