Hello...
I have trouble with A axis feedrate.
There is some limit that I'm unable to find it. If I jog A axis (rotary) I can turn it fast as I need to. But when I execute G1 Aangle Fspeed I can get max 720 deg/sec. But when jogging I can get it over 3600 deg/sec. Even G0 doesn't go faster. With G1 F les 720 the speed is limited to corect value.
Can someone heelp me?
Thanks...
there is ini file

You are saying 3600 degrees per sec. Do you mean per minute?
Axis displays velocity in units per minute.
For A to move 3600 deg/min is 96.0 deg / sec.
Set as below:
[DISPLAY]
MAX_ANGULAR_VELOCITY = 96.0
[AXIS 3]
MAX_VELOCITY = 96.0
Axis displays velocity in units per minute.
For A to move 3600 deg/min is 96.0 deg / sec.
Set as below:
[DISPLAY]
MAX_ANGULAR_VELOCITY = 96.0
[AXIS 3]
MAX_VELOCITY = 96.0

Sorry. I forgot you also need:

Hello...
I mean 3600deg/sec (10 revolutions per second)
But I find other way to solve my problem with python component as I need fast data streaming too.
