PrusaXL clogged when multicolour with many toolhead changes
Hi
I have a PrusaXL with two toolheads. When printing with a single colour, I have zero issues. When printing in two colours, but only a single tool change, I also have zero issues. But when printing multicolour with many changes, the first nozzle always gets a clogged error. The nozzle isn't clogged, but it does make a loud skipping noise. When I unload and load the filament, the printing resumes for a minute or two. Then I get the same error. But when printing without colour changes, the error never happens. I have had this happen on two different files when doing many toolhead changes. It happens at the wipe tower. I have added a video and it happens at the end. https://photos.app.goo.gl/76YCeiVv78NELEi69
Can you help me fix this?

Hi,
Maybe you have to adjust the idler Pension.

Hi
I tried as you said, but it did not work. It keeps getting a clog error when changing toolheads a few times.
Also the filament in the first extruder always curls up as in the video below.

You also could try to raise the temperatur 5-10°C
