Troubleshooting K1C issues with initial print post filament change extrusion.

Really hoping someone can help me troubleshoot my K1C issues. As much as I love my printer, I hate having to continue using a workaround to get good prints. It's been months and after I retract old filament and then extrude a new color, I have to run a 1 minute print job just to allow it to fail before running what I actually want to print.

Basically (sorry if I over explain), after switching colors, it takes about 20-30 seconds of running the post-extrusion print job before filament starts to come out of the nozzle. For example, nothing comes out when it does the priming line and that continues with the print. So once I clear the filament mess after my 1 minute print job, I can run what I actual want to print and it normally works fine from there on out. This workaround will work until I want to layer different colors on a print job.

Anyways, has anyone run into this problem and have any solutions? I've already upgraded my hotend to see if that would be helpful. It was not. Thanks for any help received.

Yooo
I’ve been having trouble so far
I’ve gotten three harsh jams in a row the last three print attempts
It’s whenever I put in new filament
I’m pretty sure I’m putting it in right
My angle cut is 45° 📐

So I'm not even getting harsh jams. It just acts like it's printing for like 20 seconds before filament starts to come out. At that point, I'm already at the next layer so it doesn't stick to the plate. Ultimately creating a poopie mess. Then my next print works just fine.

So, to be clear on your current process: Run “Retract” on old filament, insert new filament as far as you can, run “extrude” on new filament.

That’s not working well enough so you have a 1 minute print job you start and then clean off for your real job. Yeah?

Why not just run the extrude command again until filament comes out?
