Can I run this by you, I've just converted a cnc router to UCCNC from a chinese controller which I believe was using 320khz kernal frequency.
I'm looking for rapids around 40mtrs min and as such have had to currently set the kernal frequency to 400khz to achieve this because I believe of what my steps per unit is set at,see below for my settings. My question is would you leave all my settings as they are or would there be a better recomendation and if so can you explain why. I've not had a machine with servos until now so still learning.
I have Leadshine 80mm 750W AC220V Servo Motors model ACM2-08008H2F1-E23-65 2.4NM 23 Bit Encoders 3000rpm with Leadshine L7-750 Servo Motor Drivers on
X and Y axis which both have steps per set at 469.48 (both these axis are using helical racks with 5:1 gear reduction)
Z axis steps per unit are 2000 this is ball screw driven.
If i reduce the kernal to 200khz then maximum velocity redices to approx 25mtrs/min (units). I understand you can change the servo drives settings to use gearing I believe you call it, is this what would be adjusted to reduce the steps per unit, decrease the kernal speed and in turn achieve 40000 units/min. But is the machine is running fine as it is should i leave it on my current settings?
Lastly my acceleration units are set to 1000,1000,200 for X,Y and Z axis resectively does this seem, fast, slow about correct for a servo driven machine?
