Remora - ethernet NVEM / EC300 / EC500 cnc board

Just to confirm on this I have flashed another board (with lots of checking) and it does appear that output 13 on my new board is faulty.....
Oh dear China !?!

I was also wondering if I upload a reduced size config file (IE 3 axis instead of 6 axis) does it increase the speed of have some other effect on cycle time?

Thanks

Hi All,

I Have an NVEM with rt1052. 

Is it normal for the 12volt outputs to be at ground and the grount to be 12 12volt ? Im talking about the the bottom rows along where all the inputs are.

Also the manual shows to use PNP inductive sensors but the inputs need to be pulled low to get them to trigger. It is completely the opposite to what is shown in the manual.

I can make it work I just find it strange.

Cheers

Edit. Never mind. Worked it out. They changed to NPN inputs on the v5 and reversed the polarity on the output voltages. What crap.

Hi cakeslob,
thanks for having a look into my problem!
The axis move in the preview screen, but the motor doesn't get any signals.

I had an error message for BASE_PERIOD, I don't remember which one, but setting it to the same value like SERVO_PERIOD fixed this for me.
When I had both values to 1'000'000 I constantly got an error message about latency, I should run the latency test, although I switched off all power saving options in the bios.
The latency test gave me results of around 30'000 which should be good.
My goal for now is to make the system moving and then I can check/fix the latency, if that will be an issue.

Regards, Hans

Hey Hans,
Since we are using  external hardware, I dont think that we use a basethread. That is mostly for parallel port setups. 
Its good that it shows up in the preview

As per Cakeslobs comment. Leave the basethread as 0 and ignore the error message.

MAJOR version change

With the DMA stepgen merged into main, the great work done by rbobey1989 has now also been merged. So now we definitely have a more capable controller board than under Mach3. 500kz stepgen and 4 hardware encoders! Can't wait to see some closed loop stepper system in action.

The incorporation of the encoder work has required an update to the LinuxCNC component, so at the same time I've also updated the component to include changes that I've been working on for the SPI versions for reliability.

This is now a major change and both the firmware and LinuxCNC component must be updated at the same time. As such I've now included the major version number in the LinuxCNC component to help with the transition. 

Firmware
github.com/scottalford75/Remora-RT1052-c...ora-rt1052-3.0.0.bin

LinuxCNC component
github.com/scottalford75/Remora-RT1052-c...omponents/Remora-eth

Note that these will have a new home shortly as we simplify the repo structure.

The LinuxCNC configuration hal file also needs to be updated to ensure the new component is loaded.
