Possible serial port issue on Linux
Opened this issue · 2 comments
When I compile and run this on Linux (I've tried Debian and Fedora on x86 and ARM), there seems to be an issue with serial communications.
On Fedora on an x86 machine, the serial port is opened, the build notification is sent to the printer, but then the process hangs and the printer doesn't move.
On Debian on a Raspberry Pi, the process goes a bit further and the printer starts moving, but dies once the command to heat the build plate of my 2X is sent, the process dies. The build completed notification is not sent to the printer and the HBP remains on
Fedora output (x86_64):

Debian output (ARM):

I to have this problem with Linux. My start.gcode gets about half way through and that is it, the printer will sit for ever after that..
With the -v option I get:
Reading from: ./serialtest.gcode
Writing to: ./serialtest.gcode.x3g
Extrusion length: 0.000 metres
Estimated print time: 2 minutes 39 seconds
X3G output filesize: 10078 bytes
when I make an X3G file but sending over serial I get:
Reading from: ./serialtest.gcode
Communicating via: /dev/ttyACM0
Extrusion length: 0.000 metres
Estimated print time: 2 minutes 6 seconds
X3G output filesize: 702 bytes
The 702 bytes transferred can be any number from 20 or so up to around 700 maximum and the machine behaves accordingly.
