I don’t mind re-distributing it - now the main question is PLA or wait for ABS?
Even better - would ABS support PLA filament, too or you need to two different plates?
@click @gid @magelan @pelgrim: I’ve yet to reduce the bed temperature to avoid the bulging I’m seeing (as suggested by @muttleysdad), but at least with the default temperatures I’m having perfect adhesion of even the smallest features on my sanded PEI bed. For instance Automaker’s superfine auto-support structures didn’t stick at all prior to sanding, by now do flawlessly, both with CEL’s PLA and ABS.
I’m sure that the GeckoTek bed is a nice addition/improvement, but before ordering, you should give the sanding a try, unless you haven’t done so yet.
Hello @dr-woo, you have sanded the plate, what was the grain of the sandpaper, and was dry or wet?
Joao Quaresma.
@magelan: See my opening post in this thread.
@pelgrim: Seriouly… Sand the PEI bed on one side. So much better. According to what CEL states in their Support Portal, they are going to adopt this in mass production anyway. You are not ruining the bed unless you do it with the wrong grit. 600 grit paper led to a perfect result in my case.
@gid The PLA plate has a maximum temperature of 35 degrees C so any test with a heated bed will ruin it. I have not tested the ABS with the cold bed because they have said it doesn’t work and because I hate printing with ABS with the intensity of a thousand burning suns.
I operate two Betas and four Production Robox.

See my 3D Hub site at https://www.3dhubs.com/phoenix/hubs/ben@bhudson Fair enough 🙂 I’ve sworn off PLA for life, after too many times that I’ve given it a go and ended up regretting it with a seriously jammed head (even when playing by the particular rules of slow cooling, etc.)
@dr-woo I chickened out and sanded it with 2000 grit wet, and it did seem to help a little. I might grow a pair and up it to 1200 on my next print!
Saying that, a new bed’s, what… £25? Practically a consumable.

@gid I use PET almost exclusively now. When printing PLA, I purge every 20-30 hours to clear the nozzles of old material. I hate ABS but some of my customers still ask for it, so I have a little on hand and will have a GeckoTek build plate for ABS coming so I can keep it from warping as much as possible.
I sand my beds with 400 grit wet-dry and that sometimes isn’t enough for PLA, but the geckoTek works a dream.

See my 3D Hub site at https://www.3dhubs.com/phoenix/hubs/ben2000 grit sounds too fine for me. Again: I’ve used 600 grit (dry, washing off the dust, dry again, washing, dry again, until any shine is gone and I’ve had a quite even dull finish) and have really perfect adhesion with both PLA and ABS. I’ve done it on another Robox as well with the exact same, satisfying results.
@click Interesting but I have to ship to the Netherlands.
Sending around shouldn’t be a problem at all. And, I really don’t mind re-distributing it around as it can save money for all of us.
Just we need to agree: order PLA version now or wait for ABS version and order later…
Thinking about it some more, and with regard to the postage cost reducing per plate the more you order, it would make sense to wait for the ABS plate to be available and order both at the same time. If three or four people did that the postage cost would be a much smaller percentage of the overall cost.
Actually - wasn’t that a question @pelgrim asked: do we really need both or ABS would work with PLA, too?
There’s actually another little issue I didn’t consider (but will and seriously) - if ordered directly then I would be eligible for import duty (and/or VAT - however it goes). I’ll explore some options first and return back here by the time we know do we wait for ABS and how long…
