Increase A axis speed, but maintain proper scale? was created by nick.smith
Hello,
I have an Amazon 4th axis that features a 6:1 reduction drive.
I found the thread here where you adjust the SCALE so that a G0 A360 will turn the axis a proper 360°.
However, the drive spins too slowly.
I can double the SCALE, which gives me the speed I want, but then I have to do something like G0 A180 for a full turn.
Is there a way I can speed the drive up, while maintaining proper scale?

Joint/axis velocity in the ini file
max_velocity
That will be once on versions prior to 2.8 and twice in joint and axis for versions above 2.8.
Might also need to change the max_angular_velocity in the display section of the ini file.

Thx much, this is actually PP, does that change anything?

What is PP?
Parallel port?
Path Pilot?
Polypropylene?

precious penguins
but actually pathpilot.
I have changed all the max_velocity values in tormach_mill_base.ini with no change in actual 4th axis speed.
I do get speed changes if I change max_velocity in 4th_axis.inc, but it will e-stop and give me a "joint 3" error.
Please advise.

if you increase the joint velocity, you also need to increase the stepgen max velocity
(typically to 25% greater than the corresponding joint velocity).
If you don't do this, the actual position will lag the commanded position and you
will get a joint following error.

I saw your Amazon review and tracked you down here, What is the little cheap controller that you were able to make work with the axis?
