Print slower at higher layer?
Hello community -- is there a way to print slower at higher layer? In the past I manually change print speed as the layer goes high, I do this only for large prints that tend to fail at higher layer. Ideally, if there's a way to make Prusa print slower and slower as it go high, that would be great!

RE: Print slower at higher layer?
It's a little crude, but you could use before layer change gcode to insert M220 Sxx gcode commands at specific heights. Basically, the same idea as temperature towers, just different gcode.

Something like this entered under Printer Settings before layer change gcode:
;BEFORE_LAYER_CHANGE
; layer_z is height of current layer in mm
;[layer_z]
{if layer_z <= 100}M220 S100
{elsif layer_z <= 150}M220 S90
{elsif layer_z <= 200}M220 S80
{else}M220 S70
{endif}

WOW this is amazing @bobstro -- yes, this is exactly like temperature tower, how can I not thought of that!! (-;
I'll try this in my next high print. (-;
Thanks so much!!

I have not tried this myself, but it should work. Please update us when you get a chance to try it out.
Don't forget that you can modify other settings, so you may find that reducing acceleration or jerk is also helpful.
