I have a bunch of different sizes. 0.8 is good for fast prototypes. 0.1 takes ages to print. But they are a pita to keep swapping over. Messes up the bed level

62

Yeah good call and I suppose the more chance of fooking up the hot end as well

So best to stick with the 0.4mm

When you come to change the nozzle, get a stainless steel one, will last you donkeys….:wink:

I’ve replaced mine with a hardened steel nozzle :+1:t2:

A BLTouch is also a great quality of life upgrade :ok_hand:t2:

Also if you can actually get hold of one a raspberry pi running octoprint is also a very good upgrade :grin:

I should have bought a hardened steel one ages ago when I found the MK10 sizes….still looking although not desperate as I’m not printing carbon yet….

Another upgrade so I can see what’s printing :bulb:

Also a complete strip down and rebuild as the clown that put it together didn’t have a clue how to set it up

Tomorrow a new hotend as the fan had a damaged fin and was vibrating, when I striped it down the extruder it was full of molten plastic

New Bowden tube as well :grinning:

Take out the fin on the opposite side to balance it :laughing:

Deano was on to something there eh Wayne :slight_smile:

Anyone running Jyers firmware?

73

Printing small delicate items, what are the best settings?

Something like this

74

I’d print at…
Layer Height 0.1100
Top Solid layers 8
Bottom Layers 8
Outline perimeter 1
Extrusion Multiplier 0.89
In fill depends on how strong you want it.

Disclaimer, different Printer setup and slicers, best is to experiment by changing one thing at a time…

I’ve uploaded the .stl which will take 43 min on my Highest print resolution, I could print it for comparison if you’d like.

What filament were you going to print it with?

I am currently printing it at the highest resolution using PLA and its taking 2.20hrs just to do the first one

That’s quit a while, you’ll need to look at your print speed + flow rate, it looks like some detail is being missed out on your print… :point_up_2:

77

Find out your min stepper motor z movement. Your layer height should be a multiple of that

78

Ooops, just realised it’s a top and bottom which equates to 1Hr 9min… :roll_eyes:

What does it house?

It’s a Lilygo T-Display 3S

this is the full case STL

Shell.zip (100.6 KB)

When printing this part would you stand it on its side as it is in the STL or lie it down?
