Wow, thanks for the heads up. I hope no one else has to go through all the hassles and delay that you went through. I would have guessed that the white plates are functionally equivalent to the black plates. Thanks to you I’m now forwarned.
I’m hoping that Lightyear corrected the white plates in the new batch that they are building now. If the white plate I ordered bombs out after I receive it in the same way that yours did then then I’ll report back here and add my warning to yours. Also, should that occur, I’ll try exchanging the white Lightyear build plate for a black one.
Yes, I preordered, probably got the very first batch of Stellar White. I received it early January. I’m not trying again until I hear all problems are fixed
I like the garolite so much that I didn’t feel like waiting longer for the Lightyear to deliver, so I adhered my garolite to the least expensive Bambu Lab PEI sheet chinese knockoff I could find on amazon.
The good news: 10"x10" is pretty close to a perfect fit
The not so great news is that the 468MP seemed marginally more attracted to its own backer than it was to the PEI. In a more perfect world I would have applied it to naked spring steel instead. Nonetheless, it seems to have no problem gripping the garolite, and now that it’s on, I don’t think it will be going anywhere.
Worthy of note: From the X1C control panel you can disable the checking of the build plate. I did, and now I don’t get any annoying errors about it complaining the expected build plate isn’t there, especially since the knock-off build plate didn’t have any of the 2d markers on it. I suppose I could have copied the 2d marker from a real bambu labs build plate, but this obviates the need for that.
I just now completed my first print with the new configuration, and no problems to report.
I’ve got 2 G10 sheets, both 1mm. One I attached to a high temp adhesive magnetic sheet but unfortunately it has a warp in the sheet which doesn’t completely flatten out when put on the bed. I thought the force of 2 magnets together would be strong enough to hold it down but the warp isn’t going away. The other G10 I just attached to one side of one of the gold aliexpress PEI with about 10 strips of double sided tape and it’s been perfect. This is the cheap G10, not higher temp G11 but it’s been fine with 280°C so far. It leaves a nice smooth glossy finish on the part.
The only thing I’d like to change is the hotend nozzle wipe where it rubs across the strip at the back. I cut the G10 the same as the original sheet with the slit and it does still flex but I’m not sure on the wear. I may have to look through the g-code and just remove that part of the sequence.
The cleaning strip on BL’s High Temp plate is the metal plate, the Hot surface doesn’t extend to it. It has a step down on that area so I’d be inclined to leave it bare (running hardened nozzle of course). Edit, just checked my Cool Plate and its the same.
Yes, I know but if the garolite is in attition to the plate thickness on top of the bed, then there will be a much larger step down before the nozzle will touch it (depending on your G10 thickness, in my case 1mm extra). I guess I could cut off a little more of the G10 on the bed side of that area so there is enough room for the nozzle. But I was worried when it does it’s wipe in between, that the nozzle might hit the side of the G10
Mine is 2mm thick. No collision that I’m aware of. I think it may know where the garolite top is, because doesn’t it first home to the center before doing all of this?
BTW, my earlier posts were testing the garolite with PETG. For unrelated reasons, I’ve switched to PLA, and this was my first test with that. It worked perfectly. It adhered when the build plate was hot, and it totally released 100% on its own when it cooled off. Honestly, it’s all so perfect I’m surprised that garolite isn’t the gold standard.
Good to hear with regards to the nozzle wipe. I might have to get out the dremel and take off those last few mm’s to break the piece off and give it a go. I print everything on mine also. PLA, the parts just slide off the plate after it’s cooled. I have poked the G10 after heating to 250 and it’s got some stickiness to it. It’s really the only thing to use for printing nylon.
Also, this PLA I’m printing is black. And my garolite is black. The lidar scanning that it does after the first layer is not reporting any problems. I had read on redit about the experience of some others where they reported it as a problem with black on black, but at least so far it’s not rejecting the scan results or complaining.
This is false. I just now watched it more carefully, and it cleans its nozzle first. However, it does drop the build surface by more than an inch before moving over to do its homing immediately afterward. So, it seems we’re all lucky for that, as I do not see any risk of collision.
Thinking about it now, it makes perfect sense that it would want to clean its nozzle first to remove any leftover filament from the tip so that it doesn’t interfere with either homing or the bed leveling measurements. Presumably that’s the entire reason it does it at all.
I notice that I’m able to crank up the heatbed temperature to quite high in order to get even better bed adhesion, and yet the prints still disengage after cooldown. Very nice. With PEI this risks “welding” the print to the build surface, but I’ve so far had no welding to garolite, and I’m not sure if it’s even possible.
Thats one of my favourite functions of the G10 plates, I’ve been using my BL plates for a few jobs recently and having a b1tch of a time getting them off.
Printing black filament on black garolite is very hard to observe on the built-in camera with the default lighting. It’s all too dark to see any detail. I definitely need to upgrade the X1C lighting before I run into trouble.
I received my Lightspeed garolite build plates today. This will speed things up considerably, because now I can remove a build plate as soon as the print finishes and put in a fresh plate, ready to start printing right away.
Edit: now printing to the white Lightspeed plate. It’s not smooth like the garolite I had been experimenting with. It has a subtle texture to it that probably helps in getting prints to stick to it.
The installation instructions only call for it to be cleaned with warm soapy water. There is no mention of scrubbing with a blue Scotch-Brite pad, or anything of the sort. Printing now… We’ll see how well it sticks.
I have a very different experience of the stellar white than yours…
I have 3 Lightyear plates - a black first gen preorder that had a surface deformation issue from a high stress Polycarbonate part that warped badly, and adhesive attempts to hold it down caused the warping part to pull hard enough on the build plate to give it a permanent hickey.
The free warranty replacement plate is a black gen 2 and has been trouble free.
I also have the new white plate and it is either a first or second run batch. The plate has worked beautifully and like the black plates has an outstanding magnetic pull to the Bambu bed. The only issue I have had with this plate is that I inadvertently rubbed off part of the QR code doing the initial wash with a nylon scrubbing sponge. To address this, I had some Wham Bam replacement high temp stickers laying around and placed one of those over the original screen printed one that I messed up. I have had no warping issues, lidar issues, or any issues to speak of. Parts adhere great, I wipe down with IPA between prints, and swap out plates between parts to let the previous part cool completely before removing.
For small size prints I’ve not had any problems as yet. The only issue I’ve encountered so far is with pulling up at the corners on really big prints that almost cover the entire plate. An example of that would be:
I’m not sure whether that’s due to my inexperience on how to cope with that particular problem or something else. Maybe it’s unavoidable, or at least common, no matter what build plate you try it on, because the corners are so close to the edges.
The lidar does seem to complain when scanning grey filament against the black Lightspeed. I don’t think I’ve seen it complain with the white Lightspeed, but I’m not 100% sure. I’ll attempt to pay closer attention going forward.
