Home depot mirror

After printing 4 model with my new printer the 5th one started failing and i am pretty sure it is because i cant level my bed properly.

I went to home depot and got a 6 pack of glacier bay 12x12in mirror tiles.

I cant print until tomorrow, but i put the mirror on my bed plate, placed my scale on it and it looks real promising.

The scale, on the glass that came with the printer, easily rocked and spun. It didnt rock too much, but leveling with paper method, the center was very tight and tough to get the paper under the nozzle after having leveled the 4 corners.

I quickly cold leveled the mirror and wow, no apparent problems!

I will know tomorrow when i print a model that failed 3 times this past weekend.

So to whomever shared/started this tip to use a mirror, big thanks!

mirrors are supposed to work well.
Book I read 4 years or so back had that tip in it.
