what’s the problem?
Is it just this particular print?
Too much overhang without supports. Inadequate cooling.
Lower the temp and layer height.
Overhangs get harder and harder with thinner layers. Adding layer delays and a good part cooling fan can help.
@Ross_Bagley how to delay it?
@Panayiotis_Savva will try
You can give it time to cool by printing to objects side by side.
The print head will move from one object to the other, allowing some time to cool.
I slice with simplify3d and you can add a minimum layer time in that slicer. Unfortunately, it costs $$ so not ideal for everyone
@Panayiotis_Savva has the simplest idea: print two of whatever isn’t printing well by itself.
@Ross_Bagley
In the cooling settings of slic3r you can do the same.
@3_name_changes_allow
Which slicer do you use?
Can we have more info please? It’s tough to figure it or without knowing your settings, printer, or material.
@Ross_Bagley I slice with simplify 3d
@Sven_Eric_Nielsen simplify 3d
@Griffin_Paquette simplify 3d off created pro stock setting with temp lower from 230 to 205
So in simplify3d, you have two choices in the process settings.
- Go to the Scripts->Layer Change tab and enter something like “G4 P200” - the G4 command is for “dwell” and Marlin uses P for milliseconds and S for seconds. Thus P200 makes it sit and do nothing for 200ms; S2 would make it wait for 2 seconds.
This adds an extra delay for all layers, which is sort of what I think you want for this part. Simplify3d’s random start point for each layer makes this work even better than other slicers.
- Look at the cooling tab of the printer profile and adjust the max speed for layers below a certain duration. I find that 30s and 20% is a good trade off, but this doesn’t work as well for physically tiny parts without a part cooling fan (because the hotend is still nearby keeping all of the plastic soft).
@Panayiotis_Savva kinda work…
