Remora - ethernet NVEM / EC300 / EC500 cnc board

I think I might of taken a pic of mine but no originally it was rbobey1989

Hi, thank you for the beta version. Just a small question, the 3.1.4.beta is 193.7 KB while the 3.1.3 is 350 KB. Is the beta full version? why is it so much smaller? Thanks

I don't know about the file size @scotta ?
But scotta made the beta to try and solve my CSS problem. I still have no solution. If you have the RT1052 controller. Let me know if you can get the CSS working on your build.

I am only at the start stages, building the machine. Actually not dealing at the moment with CSS. I was wondering if the beta version ready for use. Eventually I installed 3.1.3. The Machine is DMC2 MINI from here: shariffdmc.com/product/dmc2-mini-cnc/ It needed many mechanical modifications that took some time to overcome.

Anyone have any ideas what's wrong with my spindle. The video clip below shows the lathe in CSS mode. Everytime I'm moving the X axis you can see the display on the vfd dipping , when a lot of speed changes are there it newly stops the spindle it's so low. I noticed this in manual mode also. When changing to another speed it dips slightly before going to the commanded speed. I measured the 0-10v output on the Ec500 and can see the voltage dipping before going back up.

I tried countless hours with chatgpt and changing the spindle code for CSS to work but it's hopeless. I'm convinced it's the actual 0-10v signal coming out of the ec500 isn't fast enough. Iv read earlier in the thread people complaining about the op amp been to slow and changing a capacitor. But I think that was slow for ramp up. Mine ramps up fast when commanded but seems to lose it's 10v analog signal when there is a lot of speed changes.

Is there a way to get the pwm signal before the op amp and run an external faster pwm to analog for testing . That can rule out if it's the convertor onboard or actually remora refresh rate ?
