this is your config.txt and it loads on the board via tfpt, hence the NVEM in the title. It is board specific, and is the only thing board specific.

github.com/scottalford75/Remora-RT1052-c.../remora-rt1052-basic
this is the hal/ini file. it is not board specific. the same hal/ini file will work with the ec300 ec500 and nvem.

load the config.txt to the board, and load the remora-rt1052-basic in linuxcnc
dont go to any other github repos. dont run the file through AI. you configure your machine in the ini file.

hi rodw, thank you very much!
I have a question: if I don’t use Beckhoff and just use the computer’s Ethernet port or network card, how can I control things like the VFD for the spindle motor or coolant flow? Where would I connect those? Also, I live in Iran and unfortunately Mesa FPGA cards are not available here.
it’s almost like North Korea here — we can’t really order anything from abroad, so I haven’t been able to get any Mesa FPGA cards

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).
