G94 Feed rate not updating

Hi

I have written a piece of remap code for our custom toolchanger and want the machine to do a specific set of moves when it reaches a location. I want the moves to be nice and slow so am trying to make the G94 code work, by using e.g.

G94 X1674 F1
G94 Y11 F1

However no matter what value I put for F it always moves at the same speed. I set my linear units to mm in the ini FWIW.

Any thoughts why this might not be working? I've also tried it in the MDI and no dice.

Cheers!

EDIT ah never mind, looks like I should be using G1

You use G94 at the head of your G-code and it's all.
Use G1 X## Y## F400 to change your speed.
For example:
G94
G0 X0 Y0 Z0 - it's fase movement
G1 X300 Z-4 F600 - move to this point with speed 600 units/minute
G1 X200 Y200 Z-10 F200 - change speed
M2
Read G-code quick reference for more details
