first of all, great work with this script. I have been researching how to add other material inside a model that is currently printing without pausing the print (as it often leaves weird layer start after the pause). I have no programming experience but would it be hard for you to write the script to check for a specific z height and have telegram send a notification 2-3 layers before it reaches the desired layer? This way one would be able to be pre notified before the nozzle moves out of the way and you can be prepared to insert whatever material into your print without having to keep an eye on the print. Thank you in advance.
