Change travel speed according to progress.

Hello,

 

Is there a way to adjust the travel speed based on the printing progress or Z-layer height? Even a basic setting, such as a binary condition, would be helpful.

Yep! Just go to Extensions > Post Processing > Modify G-Code, and in the window that pops up click the Add a script button, then choose "ChangeAtZ" from the list. You can set it to trigger at either a certain height or a certain layer number, and it can change the speed.

 

I think if you just want it to change travel speed, you need to set both Change Speed to your travel speed and Change Print Speed to your print speed, but I haven't tried it myself.

 

There's also the "Limit X-Y Accel/Jerk" script, which lets you pick a layer (or pick a start and end layer for it to gradually go down and after the end layer will just stay low). This doesn't change travel speed but it lets you lower the acceleration and jerk rates, the idea is for a bed slinger printer (a printer that moves its bed on at least one axis) as things get taller, it lowers the chance that your model will wobble from side to side.
