Re: Trajectory Planner with Jerk limits

Hi Tom, of course using G00 segments was a bad idea. I think being able to change trajectory planner settings using a C code program would enable changing between high dynamic roughing and precise finishing parameters. This is something I know from industry grade controls, if it would be possible to...

Re: Trajectory Planner with Jerk limits

Hi Tom, thanks for the reply. As a mechanical engineer I am only as much into software and programing as needed. I would try to get in touch with people from heidenhain or siemens. Rapid moves work fine with jerk limitation but with trochoidal milling or high feed milling the paths with high feedrat...

Re: Hardware Latching Encoder Z Index

Hi Tom,
thanks again for the quick reply. Of course you are right that with the fast search using the new latching function the slow and precise search would start very near the actual Imdex. Will this latching function be implemented in the new software version?

Trajectory Planner with Jerk limits

Hi Tom, I currently use the KLP factor to reduce jerk during coordinated motion. But as this introduces a geometric error in some circumstances I am hoping for the implementation of a jerk limiter to the trajectory planner. Of course this is only needed for dynamic machines but as I am using KMotion...

Re: Hardware Latching Encoder Z Index

Hi Tom, as always I am impressed how quick you reply and are able to find a solution. If I understand correctly this latch should make sure the impuls is always detected. However the actual encoder position during the impuls would not be saved in a register. Is it possible to save the encoder counts...

Hardware Latching Encoder Z Index

Hi Tom, as far as I know there is no Hardware Latching function in KMotion. With a short Z signal (0.1µm) you have to use quite low speeds when homing the machine. It works ok especially if the slow speed is only used right before the estimated position of the Z signal. However it would be great if ...

Re: Kogna Auto Disconnect - Requires Power Cycle

Hi Tom, thanks for the help. It took me some time to evaluate the problem further because the machines have to be running a lot lately. However I changed some things on the setup this weekend and it seems the disconnect problem is mostly solved. During testing I noticed that my KOGNA ground (soft gr...

Re: Kogna Auto Disconnect - Requires Power Cycle

Hi Tom, sadly, the disconnects still occur but not as frequent as before. Some disconnects are temporary and others require a restart. I cut the #RESET wire on another machine, and it helped bit did not solve the problem completely. I am currently trying to get rid of the problem completely by addin...

Re: Kogna Auto Disconnect - Requires Power Cycle

Hi Tom, I think I have the same problem as Griffin with noise resulting in a Reset of the ethernet connection and the DSP Working normal. So far I have hard wired the RESET# signals to 3.3V to cope with the disconnection issues. Of course I did all kinds of additional grounding inside the cabinet be...

Re: Kogna disconnects from PC after Bit is set high

Thanks for the quick reply. The relays are driven by 24V signals and only switch the LVTTL signals to the internal 3.3V. This seems to work better than using solid state/ opto relays for input isolation. For outputs I do use solid state relays or special mechanical relays rated at 3V which work fine...
