More speed!

Hi Jerome,
I have 1.8 degree per step motors (200 steps/revolution), and I am running them in half-step mode - so effectively 400 steps/mm or 0.0025mm/step for Jedicut.
With 1 millisecond delays per step (the smallest integer I can put in the configuration) I am limited to 2.5mm/second wire speed which is fine for cutting, but painful for positioning. I have run this machine at 5mm/second with no problems in the past, however Jedicut doesn't seem to be able to support this.
I can make the motors run at 3.75mm/second by running the timer at 6KHz while the software is configured for 4KHz, but I'm not sure if this is a good idea from the software's perspective. (it makes the maths difficult, and probably dynamic heat control will be out by 1.5X as well)
Do you have any ideas for solutions? (apart from running the motors in full step mode which is not as smooth)
