Thanks for quick reply. Just to add more detail: if I set servo thread to 20M (20x more than default config) the error does not appear. Also the number stated in error is always the one from ini file from servo thread.

Hi all
I have just flashes a EC500 board with the new firmware & can confirm that it is working great. I've tested the inputs & they are all working as expected & judging by the lights all the outputs are working.
Most importantly the spindle output now turns off when directed to goto 0 rpm (Scott it would be great if you could push this out to the NVEM boards).
Just as a reference here is a table of the old & new I/O.
I do have one very trivial request though, would it be possible in the next update to number the single digit inputs with a leading zero IE 1 is 01 & so forth. That way they would appear in correct numerical order when looking at them in halshow as well as making the scrips justify nicely
Thanks
Alex

Hi,
i have convert an old 5Axis mill to LinuxCNC with Remora on EC300 V5
But the Stepper will not run very smooth, i think there are some jitter but don't know why
Here my X-Axis setup:
[AXIS_X]
MAX_VELOCITY = 6.0
MAX_ACCELERATION = 500.0
MIN_LIMIT = -150
MAX_LIMIT = 150
[JOINT_0]
TYPE = LINEAR
HOME = 0.0
MIN_LIMIT = -200.0
MAX_LIMIT = 150.0
MAX_VELOCITY = 6.0
MAX_ACCELERATION = 500.0
STEPGEN_MAXACCEL = 1200.0
SCALE = 1600.0
FERROR = 1.0
MIN_FERROR = 0.5
HOME_SEARCH_VEL = 20.0
HOME_LATCH_VEL = 3.0
HOME_FINAL_VEL = -20
HOME_IGNORE_LIMITS = YES
HOME_USE_INDEX = NO
HOME_OFFSET = 6.5
HOME = 0.0
HOME_SEQUENCE = 3
I'm using an old Laptop to for LinuxCNC, the jetter test ist not good but ok,
have also tested on Raspberry PI4 with the same problem.
Thank,
Olli

Thanks Alex for documenting the update. Which NVEM board, the STM version or RT1052? The RT1052 boards have the same code base.Hi all

Done, Remora-nv component updated with %02d formatting and inverted inputs as well.Hi all

I was hoping to see the 4th and 5th axis please , pics are pretty elusive online.

Can I flash the new beta code to an RT1052 based NVEM?
I took a chance on this & did it anyway.
The spindle output now works correctly.
Here is a list of the inputs I have been able to get to work.
I believe the ETSOP button on the end was working but has now stopped working.
I have not tested any of the outputs.

This version of the firmware is for the NVEM / EC300 and has the same PWM for the analogue output as the EC500 version. The IO is quite different as you've found.

Your right...
I flashed this file (remora-rt1052-0.0.1.bin) & it all works.
Here is another list of inputs ( just for correctness)

You can not see the jitter but you can hear it and i can feel it
