Error loading firmware
Hello
I finish to mount the MMU2 kit on my MK3s.
Firmware of the MMU2 is 1.05. And I want to update it in 1.06.
Using prusaslicer (under OSX), I got this issue (trace window):
-----------------------------------------------
Using Port : /dev/cu.usbmodem14301
Using Programmer : wiring
Overriding Baud Rate : 115200
avrdude-slic3r: stk500v2_recv(): timeout
avrdude-slic3r: stk500v2_getsync(): timeout communicating with programmer
avrdude-slic3r: Could not open port: /dev/cu.usbmodem14301
avrdude-slic3r done. Thank you.
------------------------------------------------------------
I change USB cable. I make Factory reset of MMU2. But no result
Thank you for your help

RE: Error loading firmware
Hi, I had a similar issue when flashing the mmu2s from linux.
My way to flash: Printer powered off, USB cable connected to PC,
Open Prusaslicer, load the MMU firmware in Prusaslicer, power on the printer, press flash button imemdiately after power on.
It works for me, hope it can help.
