Re: spindle servo tuning for heavy chuck and overall mass
If the DAC/Spindle responds correctly then the problem is likely with the configurations/tuning. I assume there is encoder Feedback? Please post your Config/Step Response/Filter screens and Spindle Programs. One thing that may be happening is the output is limited so it can't keep up with the comman...

Re: spindle servo tuning for heavy chuck and overall mass
edit. says file is too big to upload? how do i upload the step response data? Top To upload the raw data you might zip the file or change to a smaller time. anyways, it is a DC servo with a +/- 10V drive so torque right? Well no, the voltage could command a velocity. In this case the drive would ne...

Re: The program for probe and toolsetter
That depends on your job setup and use of offsets. The example ToolTableSet.c will set a tool table length such that the GCode DRO will read 0 with the tool tip touching the setter. Motion to probe the tool tip to the setter would need to be added for your tool setter. You might also read this Threa...

Re: spindle servo tuning for heavy chuck and overall mass
Tuning any servo is fundamentally the same, but with different response times and such. If the Spindle Drive has a excessive delay that can be problematic. Is the Drive input commanding torque or velocity? Please post Step Response Screen Plots with also your IIR Filter and Configuration settings an...

Re: Fawne Fadal, Unchained. (4020 Fadal Retrofit)
Hi Batty, Very good. But several things: #1 the Acceleration is set extremely high relative to that level of Jerk. Jerk is normally set around 10X the Acceleration value in order to to apply the full acceleration in around 0.1 seconds. With those levels of A and J it would take 200 seconds to apply ...

Re: SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT
Hi Noel,
I believe you only have Step/Direction signals connected to the Drives which is Position with no way to control velocity. So the Drives would need to be in Position mode.

Re: Isolating SnapAmp from KFLOP to remove motor noise
Grounding is complex but one approach is to connect shields that are on noisy signals (Motor wiring, supply wiring, etc) with the purpose of collecting noise and preventing radiation of noise, to be connected to earth gnd away from KFLOP. If these shields are connected to the KFLOP/SnapAmp/KStep DC ...
