you are missing the config for the second extruder
what does the bltouch show in the ui when its not deployed?
@Veti the second extruder is for my "fast switching" bowden - direct drive setup.
I used the so-called EVA mod for my printhead, I only have to change 2 screws and 1 piece of plastic to convert my setup from direct to Bowden and vice versa. the Extruder is driven from the Toolboard stepper driver.
This Toolhead can be used for a Hemera, volcano, mosquito or dragon Hotend, standard or Idex, and with BMG or Titan extruders.
when in Bowden mode: the duet 3 mainboard drives it
but I don't want to switch config... only hardware changes
at the moment I´m looking for a solution on how to properly mount the tool board when I use the Bowden setup.
when in direct drive I've mounted it on the backside of the Nema with a printed holder.
its a really nice design,
@Veti Z-Probe 0
and the red and blue lights are constantly on.
when doing a standard homeZ. it works fine.
but when i try to do a mesh with 20mm spacing, it stops with the same error message after a random number of points.. sometimes 40 spots , sometimes only 15 spots
a lot of the bltouch problems come from bad wiring.
@Veti perhaps this one is software related.
when i restart the printer without touching the head, it works perfekt....sometimes up to 10 times in a row ..
@Veti and when the error occurs, the bltouch is blinkin red and in the dwc i can read z-probe 1000
have you updated the bootloader?

the bootloader not the firmware. please read the thread.

Is it to do with the BLtouch being on the toolboard but the z drivers being on the main board?
I believe the restriction is still in place about the probe being in a different board
@Veti yes , but it says bootloader not available, and i cant find the file. i Have to update via can, do i need the ToolLc1 firmware also or only the bootloader file ?
Veti last edited by Veti
whats the error message when you issue the bootloader update?
the bootloader files are here as its written in the documentation.
@Veti bootloader not found
I looked again in the toolboard documentation, but i cant find the link to the bootloader, there is only a link to GitHub with the step files....
do i need only the samc21.bin or the .elf file also?
any additional files needed?
i added the 3 lines for the workaround also to the end of my config.g
i will test if now the mesh completes without errors
@Veti the samc21 from your link worked.

now, i´m really curious what the bltouch does

Is that the right combination of firmwares ?

@Veti the bootloader doesent make a big difference
this time, it completes perhaps 40% of my build area bevor it stops and starts blinking.
the workaround lines of code are also in place....

@Frederik You could try a lower speed in M558. I use 6000.
@Stephen6309 i will try, moment
you could also try adjusting the grub screw on the top of the bltouch.
@Veti i changed the mesh size from 20mm to 75mm and it completed the whole area without error.
@Veti how can i delete a used thermistor pin ?
since the last change of my config.g , i get a heater fault and open circuit, but the cables are ok
@Veti i deleted it already, my heated bed is ok. the thermistor has 100.8k resistance , but i cant get them to wrok after the config change
post the changes you made
