Thanks for clarifying. I no longer look for compression at all on layer 1. I'm actually looking for the print nozzle to be exactly the right height from the bed in order to create a perfect first layer with the right spacing on the infill (i.e. no holes and no ridges). It seems that no amount of careful setup locks this in for me and (almost) every print I have to use z-nudge to tweak things until I get what I'm looking for. 3000 mm/m is 50 mm/s so 20 mm/s is for me a 40% first layer speed, which doesn't that slow, and isn't far off what I do with a 50% first layer. I just can't believe PLA is going to stick at 55 degrees with a 40% first layer speed, but I'll definitely give it a go. Perhaps the combination of slow speed and compression is helping. I also let the heat soak over the whole plate, though I don't time it and it's almost certainly not a full 30 mins.
Still loving the Clever3D PEI Buildplate for my BigBox. I have a CoreXY I built from all the scraps I replaced over the years with a 215x215 heated bed but I can't seem to find a permanent aluminium PEI coated build plate for it anywhere. Any one know where they still sell them? (Clever3D do not list them anymore or I can't find where). OR is there a better solution these days? I absolutely think the best think I ever invested in was this Clever3D bed as I have had zero issues with it. Just clean and go. I would prefer the same for this CoreXY so temps in slicer for materials can be identical but I can't find one. Any help would be appreciated as glass just is not the same.
Pretty sure they'll make anything you care to design. Huh. See what you mean. Nothing listed there anymore. That's a bummer. Perhaps volume wasn't high enough to maintain the tooling. How about something like this ... https://www.aliexpress.com/item/330...earchweb0_0,searchweb201602_,searchweb201603_

Thanks. I did send them a mesaage a before i asked here but no reply yet. Just seeing if they are still the way forward or if somethign else is better now. ill look at the sheets which seem to be the big thing now but most seem to be magnetic which with the temps that work for me for MatX etc (140c to begin) the magnets would not handle that well. Also i like the relaiability of a solid slab of flat aluminium so the sheets would work but no idea of durability or repetability. Hopefully Clever3D will be able ot make me one as had buildtak on this bed and it does not last long i found. Cheers for the ideas.
