Extruder pauses 1-2 seconds on tool change?
I am printing multimaterial (PLA and TPU) and just before the tool change the extruder pauses over the model at the very end of the extrusion path. With PLA this is not a big deal but with TPU it leaves a blob. (The pause seems to occur just before the retraction command.) I've looked through the GCode and don't see any obvious pause commands. For other printers this appears to be related to saving data on the USB, so I tried replacing the USB stick with several alternatives but the problem persists. The odd thing is that this just started happening, I can't think of anything I've changed. Anyone else see this issue on their XL?

RE: Extruder pauses 1-2 seconds on tool change?
I’m having this exact question and problem as well.
Like the OP I first noticed it while printing a multi color print with PLA, I was a bit annoyed about it but it didn’t destroy the print. Yesterday I printed a multi material print with PLA and TPU and the pause when printing TPU actually destroys the print because of the blob that it leaves.
I got the feeling that the “electronics” couldn’t keep up.
I’ve just purchased my XL5T in late december so I haven’t used it much yet.
I have the latest 6.2.0-RC1 fw and are pretty much using PS standard settings, I haven’t changed any start, end or any other gcode. I have no custom scripts or anything like that.
My question is if this is a gcode or firmware issue. I’ve looked at github (Buddy firmware) but couldn’t find any reports on this behavior.
Surely more people have noticed this?
I will try to do some more testing and keep a close eye on this. So far my thoughts are that it might be when I use multiple filament settings. I can’t recall this happening when I printed with PETG, but then I had the same filament settings on all tools. When I printed with PLA I had two different filament settings and of course it’s the same with PLA and TPU.

You can Set the Minimum layer time to Zero. IT helped me with this issue
RE: Extruder pauses 1-2 seconds on tool change?
Thanks for the response. Just to be sure I reinstalled the firmware and recalibrated the machine, but the behavior persists. Good to know it is the same on the 6.2.0 RC as well, saves me the time of trying that. I am also surprised more people haven't seen this...

I searched for this setting in Prusa Slicer but couldn't find it, could you be more specific on where this is? -hyp
