Won't load from MK3S menu
Hi,
I've just installed the MMU2S.
If I select "Load filament", then any of the choices in the sub-menu, nothing happens. (No movement no change in LED on MMU)
The MMU is on and connection confirmed.
I can manipulate the MMU via its onboard menu, it behaves as expected
"load to nozzle" works
I'd appreciate any help on why "Load Filament" on the menu screen doesn't work
RE: Won't load from MK3S menu
When I originally connected mine up I couldn't get it to do anything until I connected to the printer's serial console and manually entered the T0 - T4 commands (move the extruder to position 1 - 5). After I did that it was happy. Well... as happy as a finicky pain in the butt can be...
RE: Won't load from MK3S menu
Many, many thanks...
How do I "connect to the printer's serial console?" Octoprint? SSH?
Where could I get some guidance on this?
cheers
RE: Won't load from MK3S menu
If you are using a Mac or Linux you can install the "screen" program and use "screen /dev/ttyACM0 115200" on the command line (or is it /dev/ttyAMC0?) after plugging into the printer's USB port. There are other terminal options out there as well. If you are still using a 1.41.x version of Slic3r I believe there is a serial console available through there as well (direct print/serial support has been removed from the new 1.42/2.0 version).
Once you are connected and it stops giving you output, simply type Tx where x is the tool you want the selector to move to minus one. So to move to tool 5 you use T4, back to 1 would be T0, etc...
If you end up using screen to connect, press CTRL+a and the k to kill the session.
Other commands you can use from the console (hint: it's what's in the gcode after you slice):
- General RepRap gcode: https://reprap.org/wiki/G-code
- Prusa specific gcode: https://github.com/prusa3d/Prusa-Firmware/wiki/Supported-G-codes

Many, many thanks,
I'm on windows and have tried Putty, (can't connect), and Ponterface, (connects but doesn't communicate to the printer). In both cases due to my lack of knowledge, let you know if it doesn't work
cheers

Hi,
I just received notification of the latest Firmware update: 3.7.1 (1.0.5), installing this seemed to fix the issue.
Many thanks for your input.
