425oz motor tuning

[cambosoup99]

Just wondering what settings people are using for the 425oz steppers from keling. Maybe Keling can post some recommended settings.

currently i have the steps set up as follows in mach 3

x and y axis:
step per: 1600
velocity: 138
accelleration: 42
step pulse: 0
dir pulse: 0

z axis:
step per: 3200
velocity:138
accelleration: 42
step pulse: 0
dir pulse:0

my current setup physically:
4 keling 425oz steppers
keling 4030 drivers ( current set at 3.0 amps microstepping: 1/4)
2 start leadscrews for z axis (5 turns per inch)
5 start leadscrews for the y and x. (2 turns per inch)
running mach 3, with cnc4pc c11 breakoutboard
38v 15a antek power supply
2.6ghz dell computer


Everything seems to work fine testing them with no load. but what should i be listening for
when i tune the motors? im not sure if its right or not. I want my system to be reliable and perform good. thanks for the input.

nobody knows?

Every machine is different, so you can't really go by someone else's settings. What you want to do is set the accel and velocity as fast as possible, with enough safety margin so you never miss steps. Faster accel at the expense of top velocity is usually the best way to go.

That didn't answer my question. The question was what should i be listening for or looking for when i tune the motors?

Measure the distance traveled, and make sure it's accurate. Increase speed and accel until it's not, then back off.

thanks i'll try that
