For a test print I use the print for the filament advancement knob, it is very quick to slice and prints in about 20 minutes.

I am placing an order this week for some Matter Hackers PLA, and I'll throw an Arduino board in.
I would try the blue tape for sure but also change the temps. I print PLA at 195/65 first few layers and fan 30%.

At .5mm the temps change to 190/50 and cooling gos to 100%. It helped me with adhesion and layer lifting on my corners. Also letting the bed cool completely to room temp lets me pop the prints with no tape lifting.

What slicer are you using? Of course I am using Cura, but the settings options are limited and I am getting ready to pull the trigger on Simplify 3D.

You should be able to tweak every setting in cura that you can in S3D. Not sure if Cura does custom supports. I run S3D as I prefer the interface.

as for tape on the bed. Get a mirror from Lowes and use glue stick. Less hassle than putting down the tape. Slap some glue stick on there, heat up the bed, by the time you're to temp the glue is dry. Off you go.

Other than glass, there is the popular Wam Bam flex plates and Polypropylene plates. I run glass on my Flashforge clone, and Polypropylene on my CR10s Pro. You can hear the print break free of the Polypropylene as it cools. I mainly print in PETG.

Yeah, Cura has a ton of settings available but a lot of them are hidden as to not overwhelm new users. There is a menu where you can chose what settings to display on the print settings sidebar.

Cura 3.5

Theres a lot of options in the settings and can be overwhelming. I have to profiles for my different printers, one for my Anet and one for my Ender3 primarily because of the different types of extruders.

I can share my Cura profile if you're interested. Really the only thing thats different is my retraction speeds.

Thats my weak spot right now. I havent figured out how to Gcode the head to lift with different profiles yet so any time I print PETG my line width isnt right.

Damn, there are A LOT of ways to skin this cat....

What are your guy's thoughts on magnetic flexible print beds?

When going from PLA to PETG your Extrusion Multiplier, speed, temps, and retraction amount & speeds change.

With PETG you also start tickling the off gas point of Teflon, around 235~250C. So bowden tube should be capricon tube or swap out to an all metal hotend like the Micro Swiss hotends that don't use Teflon in the heat brake.

For my CR10s Pro with Micro Swiss hotend I have .98 extrusion multiplier, 4mm retraction @3600mm/min, 1mm coast distance, print speed 4200mm/min, hotend 240c first layer, 235c 5th layer on, 80c on bed.

Got the Micro Swiss hotend and the teflon tube already, huge inprovement just on printing.

Never tried playing with coast but ill try those settings next time I play around with it. Appreciate it.

Well, tried the smooth blue painter's tape last night... learned two things...

One, do not use the smooth blue painter's tape.

Two, always make sure your prints are flat to the bed in Cura...

I think I am going to try glue tomorrow, see how that goes.

I have thought about keeping a log, anyone do that? If so, what does it look like?
