Hello there,

I wonder if it is possible to add the values ​​of two incremental encoders attached to kflop and use the result as input for a servo channel? If this can not be done by software, can it eventually be realized by a piece of hardware?

Best regards
Thomas

Hi Tom, thanks for your advice. I understand why my idea wouldn't be a really good solution. I'll follow your advice and focus on postprocessors rather than a "tweak" that will probably end up causing problems. I was looking for a universal method because the follow mode for the Z axis would be need...

Hi Tom, I have a milling machine with KFLOP and KANALOG, the front end is Mach3. All axes have servos and glass scales and are in closed loop. An additional probe (incremental glass ruler) is installed on the Z axis concentrically (as a ring) to the endmill, total stroke approx. 20 mm. The measured ...

Hi Tom, If I understand the axis status screen correctly, then the lines are channels # 0 - # 7. If a channel has an assigned encoder input, its measured value appears in the position field of the assigned channel. Currently I have entered the encoder input # 4 for channel # 0. When I move the encod...

Hi Tom, when KSTEP is connected, can I use encoders 0 to 3 by muxing them to KFLOP JP4 by PGAW(ENC_NOISE_FILTER_ADD) = ENC_0_3_JP4 + ENC_NOISE_FILTER_DEFAULT_VAL; I have a lathe with 2 steppers in closed loop mode and I use encoder 4 for X, encoder 6 for Z and encoder 7 for spindle feedback (KFLOP J...

Hi Tom, I already own a KFLOP / Kanalog for my mill. Now I´m retrofitting a small lathe and I want it to be capable of doing threading with spindle syncronisation in realtime. It should be possible to turn the spindle by hand with Z in sync. Axes should be closed loop. All this should work under Mac...

Hi Tom, thanks a lot for the comprehensive explanation. I've been working with KFLOP / KANALOG for many years now, but with the help of the community and with your help, I always keep discovering something new. That is actually priceless. The control for the "Follow-Me" function for the Z-axis now w...

Hi Tom, now I understand that GAIN can do more than just reverse the encoder. Thank you, now the resolution issue is solved and values are correct. I also understand that KMotionCNC has advantages. I am considering switching. I would like to learn more about DestOffset and try a few things. But I ca...

Hi Tom, I connected the two axes by ch2->Dest += ch6->Output, Definition of CoordSystem is (0,1,6). CoordSystem (0,1,-1,6) works also, but is no option, because manual operation of Z only. The dual loop method works in principle. The Z axis perfectly follows the height probe and the G codes arrive a...

Hi Tom, Thank you for your quick response and your proposed solution. I've tried it. This is definitely a good solution for plasma / THC, where maintaining the Voltage of the arc is the main thing. When milling PCB, I need an exact relationship between the material surface and the tip of the milling...
