Pin 'VF4' is not a valid pin name on mcu 'mcu' & pin PB14 is reserved for spi2

getting the error since upgrading to 2.1. Same Pins are working fine on 2.0 Using the BTT Manta M8P 2.0 with the BTT SB2240 1.0
Solution:
You're missing this from your 2.0 config:
sensor_pin: toolboard: PA4
spi_bus: spi1
sensor_pin: toolboard: PA4
spi_bus: spi1

Can't believe the 4-pin fans are still wrong in that m8p-20 definition. sigh. Fix on the way. VF4 is not a pin though, never has been, never will be. It's used in the m8p diagram to indicate the voltage from the fan voltage selector. It's not a gpio. That's a mistake in the M8P RatOS definition.

and about the PB14/15 on the SB2240? I have the same pins running on 2.0.1.

Looking into it right now, more pin goofs i'm sure

I also get the error "tmc2240 extruder: spi pins must be on same mcu" which i fixed with: [tmc2240 extruder] spi_software_sclk_pin: toolboard_t0:adxl345_clk spi_software_mosi_pin: toolboard_t0:adxl345_mosi spi_software_miso_pin: toolboard_t0:adxl345_miso

will check that out too

Hmm this is strange

You said this worked on the in 2.0 ?
Hopfenschorsch
HopfenschorschOP5mo ago
Yes. let me change the sd card on the printer and i can send you the files
miklschmidt
miklschmidt5mo ago
No need, it's in the manual, so i would assume you're right But the chip used on SB2240 has that pin reserved for hardware spi Which is confusing me right now Ah!
miklschmidt
miklschmidt5mo ago
R.I.P 4-pin fans on SB2240 I'm guessing it's not that common to use the 4-pin port on the SB2240 since nobody has called that out yet?
Hopfenschorsch
HopfenschorschOP5mo ago
I think so. I´m on Klipper Version v0.12.0-208-g49c0ad63
miklschmidt
miklschmidt5mo ago
you have your fan configured as a 4-pin fan on a 2-pin header in the configurator, you could just hook it up that way. But you woulnd't get the tach signal. Yeah they broke it 2 months ago almost 3 months actually I guess you can argue that the board design is flawed, they shouldn't be using SPI pins for the 4-pin fan. eitherway, to use your 4-pin fan, connect the PWM to the negative terminal of the 2-pin hotend fan port and remove your override. then it should "just work" Leave the power wires on the 4-pin header Looking into the extruder issue now
Hopfenschorsch
HopfenschorschOP5mo ago
I checked on the 2.0 SD card and i have the newest Version of Klipper installed and it doesn´t give me the same error.
Hopfenschorsch
HopfenschorschOP5mo ago
This is the config I use on RatOS 2.0.2
miklschmidt
miklschmidt5mo ago
which version specifically?
Hopfenschorsch
HopfenschorschOP5mo ago
v0.12.0-208-g49c0ad63 Same Version as on 2.1 RC1
miklschmidt
miklschmidt5mo ago
Now i'm really confused are you sure the "toolboard.cfg" file was included in printer.cfg? And not overriden later or something Because PB14 and PB15 shouldn't work for anything but SPI @Hopfenschorsch can i see your printer.cfg from 2.0?
miklschmidt
miklschmidt5mo ago
[include Custom/Fans/Hotend_Lüfter.cfg] is included afterwards. What's in that?
Hopfenschorsch
HopfenschorschOP5mo ago
nothing crucial
miklschmidt
miklschmidt5mo ago
This doesn't make sense Those pins are reserved by klipper on initialization of the toolboard Have pushed the fix for both the VF4 pin goof and the toolboard spi pins for the extruder. The configurator is compiling.
Hopfenschorsch
HopfenschorschOP5mo ago
Will try it when its done But why does PF14/15 work on 2.0.2 and not on 2.1? What did i change to make it work?
miklschmidt
miklschmidt5mo ago
PF14/15 are different pins. PB14/15 should not work. There's nothing you can change to make them work You would have to modify klipper
Hopfenschorsch
HopfenschorschOP5mo ago
meant PB14/15 was a spelling mistake. Is it maybe because i run an older Version of Klipper on the Board it self? Version: v0.12.0-86-gdaf875e6. But then it shoul work on 2.1 because it is the same Hardware
miklschmidt
miklschmidt5mo ago
Wait.. That's not true, they're only reserved if you configure a device that uses SPI on the particular MCU gimme a sec Yes that changes things the firmware would have to be compiled within the last 3 months for the error to happen Yeah except you flashed it with the newest klipper when installing 2.1 So yes it should indeed break on 2.0 now as well, unless you don't have an SPI device on the toolboard configured, which you don't (you don't have the ADXL345 configured)
Hopfenschorsch
HopfenschorschOP5mo ago
haven´t flashed the toolhead for 2.1. I can change the two SD card with out changing sth in the software/reflashing
miklschmidt
miklschmidt5mo ago
Hmm.. actually you do. [adxl345 toolboard] cs_pin: toolboard:adxl345_cs_pin spi_software_sclk_pin: toolboard: adxl345_clk spi_software_mosi_pin: toolboard: adxl345_mosi spi_software_miso_pin: toolboard: adxl345_miso axes_map: z,-y,x The toolboard needs a different chip name to work in 2.1 it uses toolboard_t0 or toolboard_t1 instead of toolboard Ah... Canbus
Hopfenschorsch
HopfenschorschOP5mo ago
Will go with USB when i change to the new SB2209 USB
miklschmidt
miklschmidt5mo ago
The one you have already works with USB Pop a 3DO usb-c cable in your machine and you're off to the races
Hopfenschorsch
HopfenschorschOP5mo ago
Physical not really because the motor of the Galileo 2 is to close to the 90 deg USB C
miklschmidt
miklschmidt5mo ago
But you'd still have problems with PB14/PB15 😂... God damn i'm confused about how it works on 2.0 Aah i see
Hopfenschorsch
HopfenschorschOP5mo ago
I think i have to stay on 2.0.2 or buy a new Board. or hope you find the Problem
miklschmidt
miklschmidt5mo ago
Btw, the modifications you're making to RatOS.cfg will be overwritten. That file is managed by the configurator. hence this: WARNING. THIS FILE IS GENERATED BY THE RATOS CONFIGURATOR. CHANGES YOU MAKE HERE WILL BE OVERWRITTEN. KEEP YOUR CHANGES IN PRINTER.CFG. Which will kill your canbus So you'd have to make a copy of it and use that instead I see that you're using a different casing, so maybe that's enough (but then you need to manually port the updates from RatOS.cfg when it changes).
Hopfenschorsch
HopfenschorschOP5mo ago
Helge said that to me in the morning
miklschmidt
miklschmidt5mo ago
unfortunately it's one of the consequences of the config generation in 2.1 Oooh
Hopfenschorsch
HopfenschorschOP5mo ago
that would be fine with me changing it manual to use CAN.
miklschmidt
miklschmidt5mo ago
I found the difference that makes it work on 2.0 you're using different spi bus for the adxl configuration in 2.0 No.. i'm just blind I confused it with the controlboard adxl :facepalm:
Hopfenschorsch
HopfenschorschOP5mo ago
on 2.1 I use Beacon for the adxl
miklschmidt
miklschmidt5mo ago
yeah but the toolboard adxl is still configured The option you pick in the hardware configurator determines what get's put into [resonance_tester] all adxl's are still configured (so you can access them with the realtime analysis tool, or swap between them with macros)
Hopfenschorsch
HopfenschorschOP5mo ago
ah okay
miklschmidt
miklschmidt5mo ago
sensor_type:MAX31865 The plot thickens
Solution
miklschmidt
miklschmidt5mo ago
You're missing this from your 2.0 config:
sensor_pin: toolboard: PA4
spi_bus: spi1
sensor_pin: toolboard: PA4
spi_bus: spi1
miklschmidt
miklschmidt5mo ago
It's attempting to use spi2 That's why you're getting the error
miklschmidt
miklschmidt5mo ago
Jesus christ that almost killed me 😂
Hopfenschorsch
HopfenschorschOP5mo ago
Perfekt. Thank you. Are you planning to support MAX31865 in the Configurator?
miklschmidt
miklschmidt5mo ago
I'm considering it, but so far the position is that it doesn't make much sense unless you're using a PT100
Hopfenschorsch
HopfenschorschOP5mo ago
Will try it as soon as possible. chainging the SD card again
miklschmidt
miklschmidt5mo ago
And you can always configure it manually (just pick a different thermistor from PT1000).
Hopfenschorsch
HopfenschorschOP5mo ago
i find it useful because u could use the normal Port for a sensor to check the temperature of the Toolhead or sth.
miklschmidt
miklschmidt5mo ago
true, or you could use the MAX31685 for that 😄
Hopfenschorsch
HopfenschorschOP5mo ago
Dindn´t know you could use the MAX with sth diffrent then PT100/0
miklschmidt
miklschmidt5mo ago
But you're right that it can be useful for things, however RatOS exists to make choices for users to simplify the whole setup process, if i added support for everything you'd just have vanilla klipper with a confusing interface 😂 Everything is balancing act, but i will keep your usecase for the MAX in mind. Maybe it makes sense. No you would still need a PT1000 but they come in the same form factors as other thermistors So it's just a matter of putting a PT1000 in whatever else you want to measure which imo, should probably be the standard. It's just better and they're not that expensive anymore
Hopfenschorsch
HopfenschorschOP5mo ago
didn´t had a pt1000 laying around @miklschmidt Updated RatOS, the Configurator, made a New RatOS.cfg, added this and it is working now.
