Hi All!
Some comments.
1. The delay with M8/M9 is the same as with M3/M4 when I change those to command a output - not saying 'DoSpinCW' etc. That seems to do other things too (spending time). Looks like the IO-handling takes time and the delay is varying from command to command.
2. Using direction line would be instant but I'm using DSPmc which controls AC servo's with analog +-10V signal. Mach pulsing engine is not running. This is also a bit unsecure way to use a 300W cutting laser.
3. About brain output speed I don't have experience.
I could also use a optoswitch in Z-axis to switch laser on and off but I'm not so willing to use such workaround yet. (The machine has 4 axises, X, Y+slave A, Z).
The next thing on my wish list would be a programmable output to give pulsing with frequency f and with ontime t which can be set as a parameter (beam modulation).
Sorry about my rude reply earlier - was written too early in the night (2-3 AM)..
So. Still wishing miracles with this delay problem

A bit easier question - is there a good way to limit speed in small radiuses - except acceleration which I´d like to raise?
