Remora - ethernet NVEM / EC300 / EC500 cnc board

Ok, thanks!

Hi Scott, thanks for your answer which is always welcome, I have connected the power to the I/O before when I was testing so I don't think it is the problem, however I have not measured the power to the MAX3232 IC which would be a good starting point, I imagine that in your reverse engineering work you have some EC300 schematics if you can help me with that, I appreciate it, I didn't look much more but I imagine that all the I/O has a separate regulator circuit for power, regards everyone, and Scott great job

hello everyone, I have continued doing tests and the power supply of the MAX3232 is 3.3V which remains fixed without connecting the I/O power supply, it goes with the board's power supply, for which I ask the following question in the forum I ask the Keep asking everyone around here:
Someone has connected the RS232 output (RXD TXD and GND) in a physical COM port DB9 connector, Scott could you tell me which is the USB-RS232 converter that you use in the video where you show the configuration of the board, I have an oscilloscope at work for what I will use it to see the waveform on the rs232 side, although that will have to wait until Monday because I don't get the stlinks, thanks to all

Hi, I use one of these

Hello. The signal from 0-10V takes about 13 seconds. Is it possible to use pwm-gen to increase the frequency? Can you advise how to set up the hall? I tried it but it doesn't work. I don't know how to continue and to which pin to connect the pwm-gen. Well thank you

Sounds like you have an earlier NVEM which has the op amp type analogue output. I think some Mach3 users have changes the capacitor to improve the responsiveness.

Also, you will not be able to use the pwmgen component as it needs to run in a base thread.
