Hi Giancarlo,

Thank's for the update. There isn't any rush on our end.

Does the oscillation show up on the Step Response Screen moving at 1100mm/min. I think that works out at 23Hz?

Good luck.

Hi Tim, Sorry for the delay but was trying to find a good solution. It seems like by changing the GCode to use offsets differently the need for zeroing the G92/52 offsets wouldn't be needed. Or by adding a G52 Y0 and having the operator SetNextStatement to that line would eliminate the need for a ma...

Hi Jim, Absolutely. Create multiple KM_Controller objects for each board. Where the board is specified by IP Address or Serial Number. See the TestBoard2 button in the SimpleFormsCS example which toggles an LED on a 2nd board. For IP Address 192.168.68.118 would be: private void TestBoard2_click(obj...

Hi Tim, I assume in your next release will incorporate all the patches that you have created for individual customers Yes I also read the topic where you had created a patch to be able to read the current G code line. If this is now possible would it be possible to create a function to run from a G ...

Hi Giancarlo, how does kflop process G2/G3 arcs? I thought it calculates a sort of time discretization adding a point every n servo cycles, but maybe i'm wrong. I was expecting a very smooth swurface from G2 It calculates points ever 90us servo cycle using 64-bit floating point sin function so from ...

Hi Griffin, Only a few microseconds. Every 90us a servo interrupt occurs which services all the Axis Channels and a number of other things. Depending on the number of axes enabled and their configurations the total time will vary with a worst case of around 50us. This leaves the remainder of at leas...

Hi Cyprian, I think that makes sense. For example say your machine is at X=1.0 and Y=2.0 and you “zero” both axes. This actually creates an offset of -1 and -2 such that the GCode position reads 0,0. Now say the resolution is halved such that the current machine position becomes X=2 Y=4. So now with...

Hi Thomas, Here is a patch for 5.4.1 that should allow you to change TP Accelerations and Velocities. These are now defined in KflopToKMotionCNCFunctions.c // Axis indices #define AXIS_X 0 #define AXIS_Y 1 #define AXIS_Z 2 #define AXIS_A 3 #define AXIS_B 4 #define AXIS_C 5 #define AXIS_U 6 #define A...

Sorry Tom, not sure to understand: our servo amplifiers tie all the GND signals togheter. Kflop + Kanalog share the same GND for both I/O and Analog outputs. Even If I use a separate 24V source just for the amplifiers how can I keep them separated? when I connect analog outputs from Kanalog to Serv...

In principle we try to separate 24V gnd from Kflop GND and keep any I/O optoisolated. The actual problem is that our servo-drives connect the analog ground to their 24V gnd. Thus meaning that kflop gnd (in common with analog output gnd) is connected to 24Vdc gnd and this is out of our control. I th...
