Hi, Halk
Edit:-------------Halk this file below doesn't have any blended moves, I'll post one Later today ---------------!!
In my experience with 4th axis (using P-port hear) think your using G-rex, Anyway the limiting factor is the 4th axis speed for blended moves.
Pump it up as fast as you can in Vel. and Accel., Without losing steps, With 10 Micro-steps it's allot of steps compared to you other axis's.
I am using a sherline rotary table some 144,072 steps 360 deg. 1 full turn, ( set at 1 deg. 400.2 steps) 10 micro-step also vel 2500 accl 500.
A 1, 1/2, 5, 10 selectable cont. would speed it up using the 1 or 1/2 mode would speed it up.
Once you factor in the rotational Dia., I think you'll find it's OK, What's your planed use.
Try below file, 2.0 inch A dia. F25 may want to set it up or over ride speed
Thanks, Chip
