Well now, I've been churning out a few print over the past couple of weeks, but the Prusa Slicer kindly informed me that there was updated firmware available for the printer. In fact every time I sliced something and transferred it to the printer, it would beep at me saying that there was updated firmware and I had to do an extra click to acknowledge that. It got a bit repetitive so I eventually decided to update the firmware.
And that's when the problems started.
Firstly the printer is not recognised by the system.
Not so fast! I kept getting permission denied. You see, I use Linux as my operating system, and what they don't tell you is that under Linux everything, files and connections etc., is owned by something. The Prusa Slicer I was running as my logged on user (Dragon) whereas the port used to communicate with the printer was owned by the Root group, but more specifically the "dialout" user, and I wasn't allowed to touch it.
Fortunately there are ways around that:
sudo chmod a+rw /dev/ttyACM0
This command (after I entered the root password) adds the ability to read and write to that port by all users. I re-ran the Slicer and now it worked. The update went through without an issue.
However I do seem to be having a slight problem with my prints. There is a definite mis-alignment on the X-axis when printing some items. I suspect that something may be loose, but it isn't the x-belt and extruder assembly. I have yet to figure out exactly what at present, but I'll see how things develop as I print more.
