different feed rates with same tool?

[mclien1]

I'm about to start my first part to be milled.
Since this will be the first go (for me and the machine) to go directly from freeCAD, my plan is/was as follows:

I generated a part with some cutting operations:
Material is pine wood and I have experience that the mill can handle feed rates of 3000mm/min for x/y and 1000mm/min for z.
- pocket, drill pockets, cut through, contour
My idea was to generate one job for all cuttings, but change the "stress" for the machine step by step.
- cutting the first pocket (2mm in final depth) with a 1mm step down and a feedrate of 500mm/min
-next pocket with something like 2mm stepdown and 1000mm/min
and so forth till I end up with cutting the outer line with 20mm stepdown and feed rates of 3000mm/min for x/y and 1000mm/min for z.

so whenever something strange is about to happen I can hit the big red button on the mill.

Is there a way to change the feedrates for each task inside a job?

Yep. The usage of a physical tool in Path is called a 'tool controller' (TC) You can have any number of TCs in a job and each operation has to have one assigned.

So just create multiple TCs using the same physical tool. Configure each with the feed rate and spindle speed that you want and assign each one to the respective operation.

You can add the same tool twice with different parameters.

Edit: Sliptonic has a higher feed rate in answering.

Ah, thanks to both of you. Now I'm getting it.

Plan so far: getting the gcode for my test done by tomorrow, milling test sunday. We'll see if I get something for the showcase (which doesn't include demaged machines or/and blood )
