I got my A1 Combo ast week and when it was doing the initial calibration the nozzle scratched the finish off the build plate at the top. On the A1 mini there is a litle metal part there and I was wondering if I missed something in setup? Now each time it starts a print it scratches there, but otherwise prints fine.
That is normal wear. The nozzle rubs there to help break off any filament before it wipes the nozzle on the cleaning pad.
Thanks for replying. That makes me feel relieved. Will get into printing with it more now.
Of coarse. I freaked me out the first time ai saw it too. 
Me too…
I kept forgetting to ask the question here…lol
