In Cura, you can set custom start and end G-Code. And there are variables that you can use in that code. For example, {machine_nozzle_size} I know is the nozzle diameter and {material_bed_temperature} is the, you guessed it, bed temp. However, for the life of me I cannot find a listing of all the allowed variables in that start/end G-Code. I'm sure it's out there somewhere but I've been searching for 2 hours and I'm about to toss my computer out a window (not literally). I'm willing to bet someone out there doesn't even have to look for it, they just know where they are. I am hoping beyond hope that this post finds such a person. You will have done your good deed for the year. I'll even write to Santa on your behalf to let him know you've been a good person this year. 😉 🌲🎅 Thank you in advance.
