Wow, long time I did not read this monstruous thread
I agree with @Lostferret a simple glass with a new magnetic sticker do a perfect job, if it really make you crazy, just buy a glass & a sticker !
My side, I also use glass and for months now :
I bought a custom cut tempered glass (because I wanted it to be the perfect size and match the rounded corners)
Removed the original magnetic sticker & well cleaned the aluminium plate
Putted some cheap thermal grease
Putted the glass on top of this
Sticked a new magnetic sticker onto the glass
This works very well and considering the price of the printer itâs worth it.
@Lostferret Why the hell did you use some kind a patchwork for the magnetic sticker, you could have buy one that is bigger than needed and then cutted it to perfectly match the glass size ? ok this wont make it works a lot better but it will make it more beautiful
I received the aluminium plate from 3018nc.com a few days ago and prints turn out perfectly flat. Call me silly but I had the goodplate already, which also did a decent job. Interestingly, both have about the same weight. I still favor the metal plate as I believe it should have a better heat conduction than glass.
It has metal inserts on the bottom surface for the magnets in the bed as well as a bunch of magnets to hold the build plate. It slips into place just like the build plate guided by the positional aides of the bed. On the upper surface screw heads stick out acting as guides for the build plate. A well made product and easy to install.
Which one? The aluminium sheet? I got mine shipped to Germany - no problem. And yes, it calibrates well on my P1P. The goodplate glass plate works equally well (same weight). Let me know if you are interested in mine - I donât need it anymore.
I bought one of these too. Not cheap, but made very well and is indeed perfectly flat.
If youâre printing functional parts that must be completely flat, then this is your answer. For all of the time and agony this will save me, itâs totally going to be worth the cost.
Heu⌠260$ !!! this is more than the third of the P1P price, frankly I am certain this is a good plate (it must be perfect for this price^^), but this price is ridiculously high.
Three plates == one P1P ?!
I hope/encourage everybody to think twice before buying this stuff at this price. Iâm worried that discouraged people will buy this and be cheated.
I canât see anything that would justify this price, this is a just a machined aluminium plate + some magnets.
But some are flat, depends on YOUR tolerance of your projects.
