ADXL345 Issue Octopus Max EZ, MCU wont boot when plugged in

Using EZ 5160 Pro drivers on the on the XY 48v and Z's 24v. Z's will soon be swapped out for EZ2209 drivers. I believe I'm getting some sort of SPI conflict that's identical to https://github.com/bigtreetech/Manta-M8P/issues/27 Tripple check the wiring etc... If I hot connect the ADXL345 post booting then home it throws an error of Unable to write tmc spi 'stepper_z' register GLOBALSCALE Are there any work arounds? Will a tool board address this?

Manta M8P Boot Loop on SPI1 with ADXL345 · Issue #27 · bigtreetech/...

Connecting an ADXL345 to SPI1 on my Manta M8P causes the MCU to not boot. It seems like the bootloader is conflicting with some other device on SPI1 on boot. Can anyone confirm if there is any othe...

you could try enabling different overlays in /boot/BoardEnv.txt that is what https://github.com/Rat-OS/RatOS/blob/v2.x/src/modules/cb1spi/start_chroot_script does to enable SPI for the ADXL

That's for CB1 headers @anon13._07409 It's plausible there's a problem with the SPI header on the EZ too, not sure. Let me make sure the config is using software spi which usually solves this issue (Octopus Pro for example). Hmm.. Maybe in this case software spi is what's causing the issue. Would need to do significant copy pasting to get rid of all the software_spi properties and change it to spi_bus: spi4 Both drivers and adxl Heey, maybe a perfect time to test out 2.1 config generation first thing: copy paste the board include and remove the adxl345 section, then include that instead of the RatOS one. What size is your printer? (i'm assuming it's a V-Core 3?) And what extruder are you using, and is it connected to the Manta or a toolboard? Once you've told me i can generate the stepper section for you (you would comment out everything else in that section).

miklschmidt•13mo ago

Something like this?

No reason to swap out Z's to 2209's btw, 5160's are great. They're only problematic for low current motors, such as extruders.

miklschmidt•13mo ago

Oh and do you want this on or off?

AFAIK it works perfectly fine on BTT drivers, haven't tested specifically on their EZ drivers though.

absent-sapphireOP•13mo ago

Board is a Max Ez not Manta Bondtech LGX Lite Extruder connected straight to the board, no tool board at the moment... 500mm V-Core 3.1 Not on please Good to know on the Z's will do

miklschmidt•13mo ago

Board is a Max Ez not Manta

Yeah sorry i misspoke, i already picked the Max EZ lol 😂

Bondtech LGX Lite Extruder connected straight to the board, no tool board at the moment... 500mm V-Core 3.1

Aight gimme a sec!

@anon13._07409 Try that 👆

absent-sapphireOP•13mo ago

This is going in the user override section correct?

miklschmidt•13mo ago

No it replaces the stepper section IT's everything that is normally in those includes

absent-sapphireOP•13mo ago

[include RatOS/printers/v-core-3/steppers.cfg] that file?

miklschmidt•13mo ago

Generated with the development version of the 3.1 No the entire section

absent-sapphireOP•13mo ago

got it

miklschmidt•13mo ago

All of this gets replaced

No description

absent-sapphireOP•13mo ago

Klipper reports: ERROR pin e_uart_pin used multiple times in config going to take that part out for the moment

miklschmidt•13mo ago

Ah yeah it's because the lgx-lite include loads the TMC2209 version of the 36STH20-1004AHG stepper include You should keep the one in the section i posted

absent-sapphireOP•13mo ago

got it added it back

miklschmidt•13mo ago

And copy the rotation_distance from the lgx-lite config, and uncomment the lgx lite include.

absent-sapphireOP•13mo ago

doest like the homing speed Option 'homing_speed' is not valid in section 'stepper_z1'

miklschmidt•13mo ago

Ah yeah, that's a bug in my branch. remove them from z1 and z2 And [extruder] as well

absent-sapphireOP•13mo ago

pin stepper_spi_miso_pin is reserved for spi4 keep it on the x and y?

miklschmidt•13mo ago

yes keep on x y and z Are you still including the original octopus-max-ez config?

absent-sapphireOP•13mo ago

yes

miklschmidt•13mo ago

first thing: copy paste the board include and remove the adxl345 section, then include that instead of the RatOS one.

We have to make some changes to get rid of software_spi

miklschmidt•13mo ago

You need to get rid of this

miklschmidt•13mo ago

Instead, you want:

spi_bus: spi4
cs_pin: adxl345_cs_pin

[adxl345]
spi_bus: spi4
cs_pin: adxl345_cs_pin

absent-sapphireOP•13mo ago

remove that got it there is no save button what am i missing

miklschmidt•13mo ago

Yeah that's why i asked you to copy the config file Copy it to your root directory (where the printer.cfg is) Then make your changes, and include that instead of the RatOS one.

absent-sapphireOP•13mo ago

ahh got it

pin stepper_spi_miso_pin is reserved for spi4 Once the underlying issue is corrected, use the "RESTART" command to reload the config and restart the host software. Printer is halted that worked so far

miklschmidt•13mo ago

No more "stepper_spi_miso_pin is reserved for spi4" error?

absent-sapphireOP•13mo ago

yea thats fixed now that i repointed the include statement to that copied version

miklschmidt•13mo ago

excellent

absent-sapphireOP•13mo ago

rebooting now with hte AXDL attached to see

miklschmidt•13mo ago

This whole topic made me aware that i need to make it a board definition parameter whether steppers/adxl run on software spi or not.

absent-sapphireOP•13mo ago

it loaded

miklschmidt•13mo ago

At least it's easy to deal with in 2.1 awesome

absent-sapphireOP•13mo ago

going to try and run the calirbate

miklschmidt•13mo ago

Yeah.. hmm.. I'm not sure if the Max EZ is going to work with an ADXL345 and SPI steppers connected at the same time. It's very possible it's just wiring issues though.

absent-sapphireOP•13mo ago

will a tool board possibly solve this?

miklschmidt•13mo ago

If you grow tired of trying to debug wiring issues there are 2 other options: 1) Toolboard with integrated ADXL 2) Connect the ADXL345 to the RPI, but if you have wiring issues, you'll prolly have wiring issues with that too. yes

absent-sapphireOP•13mo ago

will give those a go thanks a ton!

FYI went to home all the axis and it threw the following error Unable to write tmc spi 'stepper_z' register GLOBALSCALER Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Printer is shutdown

miklschmidt•13mo ago

Interesting Did it work before that? It's possible it's the ADXL that's messing with the driver communication Especially if it's wired wrong. Did you disconnect it or is it still connected to the SPI header on the Octopus Max ?

absent-sapphireOP•13mo ago

the ADXL has been removed / disconnected and it through that error it would not start with it connected it's all good though will try a toolboard anyways i saved your edits for later and reverted to my last known working config on a separate note, if interested, z-tilt is not following the cordinance and the printer head is going off board any things specific i should be looking for?

absent-sapphireOP•13mo ago

These z-tilt points look like they would put the probe off the build plate

No description

miklschmidt•13mo ago

z_positions = pivot points points = probe points. Yeah somethings wrong with your kinematics

absent-sapphireOP•13mo ago

ahh ok ok will dig around

miklschmidt•13mo ago

Ie. mechanically or driver / stepper wise The stepper config i posted should very much have worked Are you sure your drivers and cables are in the right slots? And that the motor power jumpers is set correctly?

absent-sapphireOP•13mo ago

one thing that has been suspect to me at least is i had to flip the stepper direction for both x and y ############################################################################################################# PRINTER CONFIGURATION Customize the defaults to your specific build ############################################################################################################# [stepper_x] dir_pin: !x_dir_pin # Add ! in front of pin name to reverse X stepper direction rotation_distance: 40 # 40 for 20 tooth 2GT pulleys, 32 for 16 tooth 2GT pulleys [stepper_y] dir_pin: !y_dir_pin # Add ! in front of pin name to reverse Y stepper direction rotation_distance: 40 # 40 for 20 tooth 2GT pulleys, 32 for 16 tooth 2GT pulleys is it safe to assume that the back left stepper motor is X and the back right is Y?

miklschmidt•13mo ago

That's likely fine. This varies from board to board, depends on the orientation of the JST headers and how you wired your steppers. Nothing out of the ordinary yes Did you follow the installation manual? It asks you to check if your toolhead moves correctly by using SET_CENTER_KINEMATIC_POSITION

absent-sapphireOP•13mo ago

yep its does x y and z home all fine

miklschmidt•13mo ago

And what exactly happens when you run Z_TILT_ADJUST ?

absent-sapphireOP•13mo ago

my power jumpers are on the lower pin for X, Y and Z's, the extruder is as depicted

No description

absent-sapphireOP•13mo ago

taking a photo since they are 48v

miklschmidt•13mo ago

yep all good

absent-sapphireOP•13mo ago

hits the build plate since the probe is off the build plate when it was traveling into and from the front right corner it sounds like the steppers were fighting and losing steps

miklschmidt•13mo ago

Try G0 X0 Y0 that should position the nozzle on the front left corner of the build plate, if it doesn't, your endstops are all out of whack. Right, rail binding / belt tension super uneven or too tight / loose pulleys / or you mounted something on the frame that blocks the movement.
