Hi All

I have tried a few variations of wiring (but plugging it in to P1 surely didn’t help), more about that shortly.

I tried this

Mesa 7i76u TB2 axis to DM556T signal in.

Differential wiring:
GND
STEP- to PUL-
STEP+ to PUL+
DIR- to DIR-
DIR+ to DIR+
+5VP
(with ENA+ and ENA- on DM556T not connected)

I tried the same as above with
GND wired to ENA-
then
+5VP wired to ENA+
then
with both wired.


***************************
See Control Signals image which shows two different wiring for single ended.

I don’t know which type the Mesa 7i76u control uses, but I tried both of these.

Open-collector signal ties +5VP to PUL+ , DIR+ and ENA+
PUL- to PUL-
DIR- to DIR-

PNP signal ties GND to PUL-, DIR- and ENA-
STEP+ to PUL+
DIR+ to DIR+

***************************

Enable_disable image mentions this …

Enable signal:
This signal is used for enabling/disabling the drive.
High level +5V (NPN control signal) for enabling the drive, and low level for disabling the drive.

PNP and Differential control signals are on the contrary, namely Low level for enabling.

By default it is left UNCONNECTED (ENABLED).

Would anyone have valid Remora NVEM v5 config samples available anywhere? I do not have an EC500. I do not have an EC300. I have an NVEM v5 and so far no examples will work at all. Attempting to use the hal and ini files from github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic do not seem to work as they all seem to be for the EC500. Any attempt  to use the config samples from github.com/scottalford75/Remora-NVEM results in compounding errors and will not run axis at all. Perhaps all I need to do is edit the EC500 hal and ini files? Is there any guide that will instruct me as to WHAT in those files I need to edit to get it to work? When I run the axis ec500 config and toggle the Estop and power on I can see the activity lights on the ethernet port start blinking so I know there is at least an attempt to communicate with the controller, but I am pretty sure that most else is different in the configs between the EC units and the NVEM units.

Honestly at this point I am sure I have an acute case of information overload and have wiped out and reinstalled remora more than a few times.

Thank you for presenting other approaches to the subject. It allows me to better understand the general principle of operation of various concepts and HAL structures
I will test your suggestions (it will take me some time) and I will definitely describe it on the forum so that it will be helpful for other and so that they do not bother you with nonsense like me hehe )

Is there any free cadcam software for mill ?
I know NativeCAM and librecad-freecad for cad something else ?

Thank you very much Hakan, I have attached the result as a file
