Dual Head M2000 won't work if printing via OctoPrint (Slicer S3D)

Snapmaker J1/J1s

Hi there,
I am slicing my gcodes with the official S3D profile for J1, I have done some tweaks. But I can’t get the M2000 command to work properly. Everything else works fine, even mirror and copy mode.
The unused tool head does not park, it stays at the last position and blocks the other tool head. No collision.
Here is the beginning of the gcode and the part where the tool change happens, maybe someone sees something strange

what behavior do you expect from M2000?

Interesting. I notice that there is a difference between the gcode my Cura generates and yours…

Your gcode:

T0 ;switch to new tool
G90 ;absolute positioning
M2000 S200 V250 A6000 ; park the old tool

Cura Gcode:
G92 E0
T0
G92 E0
M2000 S200 V250 A6000

the fast tool change from snapmaker. If I print from the display the same gcode works fine. But thtas no option for me.

So you dont print via J1 display and your M2000 tool change works?

@TylonHh No I only use the display interface but noticed the difference.
Ok, so the same gcode works if started locally on the machine?

edit: ahh just read your previous post, no need to answer the question then =D

Maybe the m2000 command doesnt work when sent through usb/serial connection?

Maybe it will work if you start the print with M23/M24? :face_with_monocle:

I have the same problem. Could someone solve it?
