printing on a cr-30

[neroes]

hi
i just got an creality CR-30 (belt printer)
and tried printing some pieces but i’m having issues with removing the pegs, because of the layer lines being at a 45 degree angle they tend to break the bottom when clipping the pegs due to the strain
anybody have an idea on how to fix this?
are the pegs even necessary?

so status update
by killing more pieces than i would have liked, i found that by twisting the top of each peg out, i could then cut peg of at the bottom without issue (it does deform the underside a tiny bit but that shouldn’t be an issue)

What filament brand are you using? My concern is when you start using the clips to join the parts, they are going to cause more “breakage” of these parts as the filament you are using seems really brittle.

prusament pla

the inserts seem to work fine

There is another possibility if you feel the filament is not brittle or the issue. Can you show the bottom of the printed piece? Is it possible the bottom layers are not fused? Do they look stringy?

[neroes]

the very first line looks a little stringy but i can’t tell where the layers change on the bottom other than that, i believe that the issue is that the pins fuse to well to the bottom for me to simply be able to pull them out

These are all really good questions, we never anticipated a belt printer and don’t have one here in the office to test on. Do you think printing vertically might better align the striations for an easier break or due to the angle that it prints on would it be much the same?

[neroes]

so you might be able to do it but i honestly don’t see being pritty, the belt while fairly tight is a textile so printing tall thin objects seems foolish, i have however noticed that the bottom layer of the tile is a tad bit shorter than some of the other tiles i have printed
the ones printed on my creality CR-30 is the cave floor and i have some old mine floor tiles printed on a prusa mk3S
will send a picture later

btw. there is a noticeable difference in surface smoothing when printing flat on both machines, it looks nicer on the cr-30 due to the layerline being at a 45 degree angle

[neroes]

pictures as promised, left one is printed on Prusa MK3S and right is printed on Creality CR-30
the creality messures to roughtly 1.2 mm bottom layer, while the prusa messures around 1.7 mm

the cr-30 is temporarly out of commision (it is being moved to a more permanent setup) but when it is back up i will try printing the mine tiles on it

it would be great to see the Prusa mine tile next to the CR-30 tile to see the difference that angle makes
