Greetings all; Building a design/builder for a 3d printer, which when a std usb to printer cable is connected between the computer and the 3d printer, Identifies as a ch341 convertor cable once it is plugged into the printer. conman seems helpless, as does cutecom. cura has a monitor that can drive an ender 3 over this same cable but I've not been able to establish a connection to cura, for whatever reason. Perhaps conman or cutecom is not the correct way to do it. IDK, and the docs for this printer are as non-existant as the chinese company that made it. Its labeled as a NEWEREAL M-18-S, and is nearly twice as big as an ender 3. Work envelope is 310x310x400mm, and is the same bed-slinger style as an ender 3. What would the next thing to try and discover why its not working? Cheers, Gene Heskett
I have used putty to connect to my ender 3 and a
CNC3-3018. I used /dev/ttyUSB0, 115200 baud and type
serial. Its half duplex so you don't see what you type unless you
turn on echo mode. As mentioned before you need to be in the
dialout group for this to work. I have connected bCNC to the 3018
so I know that works. I usually just transfer the gcode over
memory cards from my desktop host. I run freeCAD, slic3r,
lightburn all in a VM (I don't trust appimages etc) on my desktop
to do the design work. I have cura but I haven't tried to connect
it via usb yet.
