Independently Adjustable Feedrates for Multiple Tools; Mid-print

code7

Does anyone have a good idea for setting different feedrates for separate tools along with a way to adjust them independently mid-print?

I'm trying to accomplish something similar within a macro. Do you know why the following macro isn't working to set independent speeds?

if state.currentTool == 2
  G1 F600       ; Set printing speed for current tool
  M98 P/macros/retract

if state.currentTool == 1
  G1 F300       ; Set printing speed for current tool
  M98 P/macros/unretract

Phaedrux

How and when is that macro being called?

== 2 is not necessary in gcode meta commands, just use = 2

@code7 do you mean independent M220 speed multipliers per tool, or something else?

Independently adjustable speed multipliers with M220 or the likes would be ideal but in the meantime I'm looking for a workaround. Do you have another idea?

I call this command from a S3D script where I sub M102 for a custom command "M700" in the gcode. This calls the M700.g file that is located in the systems folder.

Ok - thanks for the tip.

You could use global variables to indicate what speed multipliers you want to override the usual M220. For example, global variable tool0SpeedMultiplier would mean the multiplier for tool 0. Then in the tpost0.g file do something like this:

if exists(global.tool0SpeedMultiplier)
    M220 S{global.tool0SpeedMultiplier}

Similarly for the other tools.

Great idea.
How can I ping the current speed rate and multiplier value?
