Here’s another nail in the coffin for 1.5.1 – I tried to print the dragon and it instantly hit an exception complaining about incompatible nozzle diameters:
Has anyone else tried to print the dragon after updating firmware?
As delivered, and as per the first test print, my firmware was 0.9.3. I have just updated it to 1.5.1 and run a heated bed calibration (I thought somebody said the notes say you have to do that, but I can’t find any such note in the release notes or wiki, what it actually says is it should not be necessary to re-run heated bed levelling).
Anyway, try to print the dragon again and I get this:
[print_task_config] nozzle diameter mismatch:f_0 != e_0.4
Error Code: 0003-0531-0000-0014
So it seems to me that the firmware update incorporating the ability to assign nozzle diameters has broken the built-in dragon print file, and the firmware update didn’t replace it with a compatible one!
How stupid is that? Yes I have checked, the nozzle diameters are set to 0.4mm in the printer configuration. Maybe the G-Code interpreter is being too picky that print files contain nozzle diameters rather than assume 0.4mm unless otherwise specified.
At the very least, it ought to be possible for the user to override this kind of error on the control panel.
I have submitted a support ticket.
Downgraded to 1.4.1 and it’s printing it fine.
