Cannot Start Print


#1

What is the problem?
I connect OK to Printer
I upload print TO OCTOprint/pi [not SD Card]
I go to print the file [any file]
I get this error:
'Offline: TypeError: 'must be string without null bytes, not str' @ comm.py:_do_send_without_checksum:2499'

Durr Me...
It’s been a while :slight_smile:
New slicer not providing .gcode files only .x3g


#3

Well, actually, this GPX plugin I have always had lets you print from .x3g files, so I guess my original Topic here remains an error ...? :frowning:


#4

So for my FlashForge Creator Pro's 2014,2015,2016 i are these GPX settings AOK?

I checked again and there was a new GPX update and all now seems AOK FYI :slight_smile:


#6

... nope, I just cannot get .x3g files to print any more :frowning:


#7

I'm fairly sure that I remember @markwal saying that the plugin doesn't support printing x3g files and you need to slice to gcode.


#8

Thanks Gina,

I'm sure I use to be able to, I see old .x3g files form last year I printed with ... never mind then ...


#9

This is correct. The plugin only translates from gcode to x3g. It can't send x3g untranslated, we'd need a different mixin or hook to do that.

However, you can (must) print x3g if from the printer's SD card which is why I show them in the list.
