I like that htpla. I am pretty sure it is not worth the money on its function alone. But I like it nonetheless.
You might as well count me in on a new order as well. Stiffer center sold me. Just hope it’s not false advertising. 
Same reason I never added a dust shoe. Im in a good size barn, with smooth concrete floors that are very easy to sweep after a shot from the air gun. But MDF is quite nasty, and it gums up the rails/bearings. Also aluminum chips would be nice if they were vacced up.
Could you link those designs please. Never could figure out a way myself.
Me too. Did I ever give a specific number or did I play it safe by saying “should be better”? hahahah
In the end I promise, as far as I can tell, Ever part is at least a tiny bit better. Add up a bunch of tiny improvements and I really hope all this time adds up to something noticeable.
Did I hedge that well enough?
Oh yes, all is good. I have the 525 and the center is actually pretty stiff when motors are engaged and working. Really wasn’t complaining, just having fun (couldnt find the sarcastic emoji). Completely satisfied with my build. Thanks for all the work.
I think 90% of us have sarcasm implied. That is how I am treating this thread for sure!
I love the enthusiasm in this thread. I am not stalling in any way. I want to release it and let everyone have fun…but a release with only a few pars would be a bummer to most people.
Hope to add the new cut calc up tonight so you guys can see where we stand and the work that is going into this one.
we never use sarcasm in the forums. Why would we need an emoji for it?
Still working on plastic parts or waiting on hardware?
<Veruca_Salt>
Don’t care how, I want it now!

Hardware and documentation. Without instructions it will be a forum full of repeat questions. Tried that before…lesson learned.
Instructions… Pffft… who reads instructions anyway!!!
That’s what I thought!!!
Can I ask what temps you are printing it at for hotend and bed? Retraction settings? I haven’t tried it yet, so just want a starting point.
Thanks!
Negative times negative equals positive.
Cheers, and hope you’ll have a 25mm version too soon. What will we be able to recycle from the burly?
U.
Will you be posting a link here to the ‘new cut calc’ here?
Also when will you start taking orders or reservations/backorders for the upgrade hardware (screws, nuts, etc.)?
Are you asking about Proto-Pasta HTPLA?
225 Hotend / 60 Bed
retraction 0.8 @ 35mm/s
on a Prusa MK2.5s w/ MMU2s
Finishes so nice. I also really like the HTCFPLA
I’ve got a MakerGear M2 with V4 dual extruders, so your mileage may vary of course. 
My bed (glass with polyamide tape and hairspray – the tape is easier to repair when it comes off with a print than the glass is, which has happened to me…) is at 80 – but for some reason I’ve always had to run my bed hotter than most for everything. .5 nozzle (steel of course), with a .6 extrusion width. Hot end at 250. Retraction is 1.2mm at 2700mm/min, which may be overkill but it’s working.
The real key to the stuff is print speed: The slower, the better. (That one took me a while to figure out – prints would be great for several layers, but then I’d return to a mess.) Finally realized they say not to go over 33mm/sec; I actually don’t go above 30 (1800mm/min in S3D), about half what I normally print PETg at – and even slower if the print has lots of small areas with the head jumping around a lot. For certain things/tool parts, the time (and material cost) is worth it, though: I’m serious when I say I pounded replacement ladder feet into place with a mallet.
Generally speed isn’t the issue, it’s the ability for the hot end to keep up the flow of molten plastic.
Interesting. I print it (very slowly) at 205C. Actually, the first layer is 205C, and it’s 195C after that. I’m getting good layer adhesion, and it is printing great parts. 
Jamie and Heffe’s calculator is live, MPCNC and LowRider.
Wow spot on with 55 mm
With Atomic’s CF, speed actually is the issue. The hot end is able to keep the plastic flowing fine, but it also needs to keep the heat applied longer for proper bonding. Any strands that cool before bonding to the previous layer aren’t flexible, and it only takes one of those strands to melt onto the side of the nozzle on a subsequent pass to essentially attach a wire bristle to the side of the nozzle. That then rapidly compounds into a worse situation.
