Bambu Lab A1 attempts to feed filament while nozzle still cold

[davinciano]

I have my Bambu Lab A1 for some weeks now and noticed the following:

Problem: Before each print Bambu Lab A1 appears to attempt to feed filament while the nozzle is still cold.

When I upload from Studio to the A1 printer then before the print starts, the print head is moved somewhere high up, to the middle of the X-asis. This looks like being part of the homing or Flow Dynamics Calibration procedures.
Then while the nozzle is still cold the printer seems to attempt to feed the filament making a ticking noise (between two and four ticks, number is not consistent).
This sounds like it may wear/damage the extruder/filament cog(s) over time.

Does anyone recognize this?
Is this normal or is this more likely something that needs to be fixed?

Hello Davinciano the clicking is perfectly normal. As you mentioned it happens 2 to 4 times as the print head is homing at the start etc thats ok. its a check that the extruder does.

If it clicks anymore or at another time during the print that is a problem

New A1 skipping extruder during prep phase of print

Hello. My A1 did the same thing, and I commented out the 2 digits in the gCode. However, I have always wondered what these 2 steps are supposed to do and what Bambu Lab was thinking. For anyone wondering what this step in the initialization is for, I found an official statement from Bambu Lab in another forum and that sheds some light. "Hello Thank you for your patience. Our R&D department gave the following response. Before bed leveling, the extruder tried to extrude but could not extrude …

Thanks. See my response in the linked thread.
