Scratches on rear end center of build plate

Bambu Lab X1 Series Bambu Lab X1C

Just finished my third print after installing the x1 Carbon.
Does someone recognise these square scratches on the building plate?
They are on both sides of the cool/engineering plate.

This area is used for cleaning the nozzle. While cooling down after the purge, the printhead slowly moves around this area to wipe away any access filament before performing the bed leveling. Since the X1C uses a mechanical bed leveling, it is important to have a clean nozzle tip.

So It’s by design. I thought I was slowly scraping a hole in the plate. Just watched the head at the start of a new print and indeed it does a left right wipe there multiple times. Also the bed moves up down.
Thanks!

Same issue here. Engineering plate is scratched down to the metal. This can’t be good for the nozzle

:smile:
Did you read the previous posts? This area is blank metal by design, to clean the nozzle.

Why does it scratch the metal on the build plate instead of using the wiper-thingy that’s part of the flush shoot assembly? I mean that’s what it’s for, isn’t it?

I have the same issue - I do not think this is okay - it is getting worse. Probably to the point so there will be hole inside one day.

Can someone from Bambu confirm whether this is okay or is it going to be fixed one day?

You can find this info at all the plates they sell.

The metal of the buildplate is very hard and the metal of the nozzle is also very hard - until you have a hole in the sheet or the tip of the nozzle is damaged it will be a very long time.

There is nothing to be “fixed”.
If the nozzle doesn’t do this, the bed leveling would be ■■■■ every single time.

I just got my printer and noticed that, I thought it had something wrong but it seems like it’s intended. :pray: so all good!

I would like to reply to this thread because I see the same scratches on the back of the build plate. My problem is the I started 5 prints with a brand new X1, the first was the Benchy and then I tried to print the spool holder which fails all time because the nozzle was damaged and I guess that this cleaning process was done that tough on the build plate that the nozzle broke. What kind of issue might that be or was ist my fault?

I would open a ticket with support. I doubt the nozzle cleaning process itself was the cause of the damage. The nozzle is only press-fit into the assembly, and some users have reported the nozzle fall out or be loose on arrival. Some have also reported slightly bent nozzles on arrival possibly from the packing process.

I have hundreds of print hours on my X1 with the original nozzle and have had no damage or wear caused by the cleaning process despite multiple Bambu and 3rd party plates.

Thanks for reading the notes/manual. This should be pinned on this thread.

If you have a “Cover Plate” Mod installed to cover the rear 2 motors in the back, REMOVE them! they intersect with the X-Axis carriage, preventing homing, also I think the Homing is done through the motors and so there should not be any type of obstruction in their path.
