JASON128

Heres a design for a cover for the S5 I gave the drawing to a local plastics fabricator and had it professionally cut rolled and glued for a few hundred dollars. added gas struts' and hinges from AliExpress. Overall looks and feels more solid & professional than the Air handler we have on another printer CoverDWGand FusionFIles.zip

Nylon shrinks... its a feature of that material. as such when it shrinks, you either- 1 get internal stresses, but don't see them on the print. - 2 get it lifting off the bed. or - 3 get the bed warping up. this is a symptom of the material, rather than the beds fault. - have you dried your nylon? - 70C for 12 hours. even if fresh out of the packet! -2 can you ensure the ambient temperature is as high as possible, with no cooling drafts or layer fan on? I have tried a flexible PEI plate on a s5, and eventually went back to glass for larger prints and nylon for this reason. another option- print the part vertically- highest face point up.

i would suggest just a simple temperature controller- and use a signal off the case fans in the bottom- as they only run when the machine is active.

Wow- good to know- was about to buy one- but that completely rules it out.!!! ill make my own then at a more reasonable cost. what an incredibly stupid implementation by the design team - speed control on the fan for cooling is obvious, and like you say- cheap to do. I can only guess its a way around patients in heated chambers?

EDM wire- funny that is exactly what I use. not too hard it will scratch or break, but strong enough for the job. I did not mention it, as most people would have no idea what you are talking about!

attached is something printed in yellow Esun PLA+ standard Draft mode in cura, no changes at all. filament was dried for 8 hours first. .04mm AA nozzle

There's plenty of us having success with esun PLA +. Not sure its fair to blame the printer. Either you have a bad batch, or a profile setting wrong. try using the generic engineering profile for PLA, and set the shell wall thickness to 1.5mm do a test print and go from there.

Dry your filament?

I agree- all that screen space, left blank to look pretty. Give us nozzle temps, any speed of flow offsets introduced, and Z height. all far more useful than a funny circular clock thing.

something rattling? something loose on the frame? might not be a moving part at all. i thought i had an issue, but it was the tools on the wall rattling from vibrations.

is this only with esun PLA? does it work fin with other brands?

yes the Z babystep function in marlin is one of the things I really MISS. i would always have a 5 row brim setup 1mm off the print. it gave time to adjust the offset to perfect every time, regardless of the material

I just redid the calibration process with the calibration card again, this time making it a little 'looser'. worked fine - have been using PEI sheet for months with no issues

as an update- it appear that the firmware works by using the movement rates relative to the stepper motor at the beginning as a reference. So if there is no flow detected at the beginning, it will still continue to run. I think this is waht was happenign in my case. A little official description on how things work, even just a few paragraphs would help a lot with fault finding- its a shame the information on how these parts work is so scarce.
