Slow Speed

Trying to learn prusaslicer and all it features, i wanna print a model with the 2 first layers at slow speed, but i only find first layer speed. Is it possible to print the first layers slow?

You can adjust speeds anywhere with modifiers:

In Slicer:  Right click on part, add modifier.

Adjust size and position of modifier shape to suit.

In the right hand pane click on the wheel icon next to the modifier, open Add settings and speed is one of the options.

Cheerio,

But how do I see which layers I can print slower then, don't see layers

RE: Slow Speed

Hi @diem - just curious, is it possible to add a line to the ‘After Layer Change’ gcode block to say, if the layer is equal to 2, then print speed equals X? I don’t know the proper syntax or I’d include it here.

If this is doable, it would allow the OP to use that profile for any print without the need to add a modifier.

I’ll try to search for more info on this, as well as the proper syntax, but I’m sure you’ll know the answer.

Thank you and have a Happy Holiday.

Cheers

Randy

RE: Slow Speed

Looking at the Marlin site, to set global speed to 50%:

M220 S50

Assuming this will work, it’s a matter of writing a command line to make the speed change needed for layer 2, then change back to default speed for remaining layers.

I’ll spend some time on this tomorrow. Getting late now.

Cheers

User wanted the opposite here, to speed up after a few layers but the same can be used to slow down.

RE: Slow Speed

@randym9 - no idea, probably; I do this sort of thing by post processing the g-code with perl scripts.

Search a Prusa g-code file for ';LAYER_CHANGE' and you will find a bunch of commented lines, including the layer height, that can be used as markers for layer-specific code changes.

@jpson67

But how do I see which layers I can print slower then, don't see layers

Do it mathematically:  If you are printing 0.15mm layers with a 0.2mm first layer and you want to affect layers 4 to 7 then make a modifier 0.45mm high and raise its base to 0.5mm.

Cheerio,

@neophyl - thank you for the link, that confirms my assumption. 

@diem - thank you for your reply, I’m still learning. Post processing perl scripts is way beyond me! 

Happy Holidays to all!

Cheers

RE: Slow Speed

Hello.

How did you end up solving the problem?

I want to print first N years slower then the rest and I don't know the best way to do it in Prussa.
My own experiments with custom G code did not work.

Thank you.
