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...

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...

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...

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...

Hi Tom, thank you for your help and suggestions. I found the JP9 connector to be the cause of the disconnect problem. I also changed the system to lower the power needed of the 3.3V supply and now use the internal 3.3V through low power electro-mechanical relays on JP9 as Inputs(JP9 3.3V -> relay ->...

Hi Tom, I did a few tests on the weekend and found the cause of the problem. If I understand correctly the problem should have been the high power consumption of the internal 3.3V supply. The Home and Limit Switches(Bit 200 - 203 JP9) used the 3.3V supply and the Limits are always on. After disconne...

Hi Tom, thanks for the quick reply. Kogna is powered by a Meanwell 5V 3A power supply. I use SSR-41FDA Solid State Relays, as with my other boards. The positive input is provided by the Bit and the ground ia connected to the ground of the power supply. Could it be that the power supply ground differ...

Greetings, I have a problem after updating to Kmotion 5.4.1. When I switch Bit 255 or 256 ON, Kogna disconnects immediately from the PC. The Bits are activated but there is no way to reconnect without restarting Kogna. Both Bits are used as General Outputs and drive small solid-state relays. There s...

Hi Tom,

thank you for the quick reply and this great solution.

Hi Tom,
is it possible to display an ADC value on the KMotionCNC screen?
If possible as some kind of bar or percentage, in my case to show spindle load.
