Cura by default includes G-code for two start lines to prime the nozzle before printing begins. The settings for these start lines are part of the start script G-code for the printer and are therefore unaffected by any changes made in the regular "print settings". I recently upgraded from a 0.4mm nozzle to a Volcano setup with a 0.8mm nozzle and initially experienced that my extruder could not force filament through the nozzle when I started a print - even though I had just loaded filament and watched it ooze from the nozzle. Turns out the problem was that even though I had updated the print settings to produce 0.6mm layers etc, Cura's start script still dictated the printer to move the head to 0.28mm distance from the bed for the first two lines (standard settings for a 0.4mm nozzle). The immediate fix was to correct the printing height in the start script G-code, but my question is: Cura allows you to define a custom nozzle size but since a printer only has one set of "machine setting", the option to change nozzle is in my case potentially damaging to the printer, as e.g. printing height can be (and was) ignored. Is there any way to have separate machine settings for each nozzle size? and e.g. have the two print lines be defined in the print settings along with everything else? - Otherwise thanks for a great piece of software! Thanks in advance
