@scotta Here is my config. Probably not ideal, however it does work fine with the lpt port.

btw I think the link in your post should be [url] github.com/scottalford75/Remora-NVEM/tre...json_config/Firmware [/url]

Hi Roy,

I've had a quick look at your INI file and I think I've found why you would be getting a following error with these settings and Remora-NVEM. The Remora step generator logic is split into two halves. One part on the LinuxCNC side and the other in the module that's running on the board. Both of these halves need to have the same servo period setting, and your INI file is setting this different.

Change your line SERVO_PERIOD = 1500000to 

SERVO_PERIOD = 1000000

(ie 1000hz) as per the example configuration should fix your problem. You probably should have started to use the example config file that is known to work rather than using one generated with stepconf.

 

I did that at first, but that didn't work either, that was why I then tried make a working config with the lpt port and use that with the nvem

Did you upload the new firmware from this location? [I'll correct the earlier post]

github.com/scottalford75/Remora-NVEM/tre...json_config/Firmware
 

Need to change the address from 10.10.10.11 to 10.10.10.10? Or is it a card address?

The NVEM board IP address is hard coded to be 10.10.10.10 , Your computer can have any IP address on the same subnet.

I downloaded it in windows. He then put it in Linuxcnc and then edited config.txt

You need to be in the same directory as the python file and the config file before running the command.
