Remora - ethernet NVEM / EC300 / EC500 cnc board

Unfortunately I do not have this unit wired in yet. I got this to replace a complete POS usb board that shipped with the mill and never worked from the moment it came out of the crate. (no direction change on x and y and no spindle control), I am trying to get everything working on the bench first just in case I might need to reflash the unit. Save me the hassle of having to completely unwire and rewire the unit if something turns up wrong.

I used the remora-rt1052-basic version because that was what was recommend to me.

Sorry I'm not able to be more helpful as I am very new to both LinuxCNC and this Remora stuff.

why you take some files from this path?

if it is stepper timing related you need to load the DMA stepgen config and adjust your step timing accordingly

I don't understand well,
I have to load all from:
github.com/scottalford75/Remora-RT1052-c...CNC/remora-ec500-DMA
and upload this to NVEM:

Alright its starting to look like the inmates are running the asylum. Everyone just hold on for a moment, breath in and out, and cool our heads. I know english or linuxcnc isnt everyones first language, but it looks like everyone is working off each others confusion, and you guys are spiraling out. I think there are some core concepts we arent all understanding completely. Its clear that you guys are smart people, so lets hold on for a moment and regroup, and always read the manual. If you atre getting frustrated, just start from page one and read. If there are things getting lost in translation on the documents, letting us know would be great, and we can change some of the wording. I know the docs arent perfect, but the core concepts are the same for the whole of remora.


Also, if its a remora specific question, it is best to ask in the thread. remora isnt really a big wide linuxcnc thing, it makes it harder to find your thread.

"why you take some files from this path?"

If that question was asked of me, it took me a few to figure out what you might of been referring to. If it was this post here - www.forum.linuxcnc.org/18-computer/44828...rd?start=2180#327765 - then that is my fault completly as I was at the wrong place when I copied the link. My bad. Just went back and edited it. Looks like the difference is in the DMA version there is an additional line in the motor config -

setp remora.joint.1.pgain [JOINT_1]PGAIN

- that is not in the basic and not what I am currently using. I believe you said it, it's confusing, and yes, it would seam I have fallen head first into that confusion.

Bad Spyderbreath for adding more mess to the pile.

 

The config.txt file tells the MCU which pin is going to do what. so Pin P4_20, the imxrt1052 MCU pin, is assigned the title of remora input 06 . when pin P4_20 is triggered, the MCU tells remora that remora.input.06 is triggered.
Not to confuse things and its hardware restrictive, but you can make "remora input 06" to be whatever pin you want it to be, it doesnt matter what pin is input 5 or 6, but it has to match up.

The remora.hal file connects remora pin remora.input.06 to LinuxCNC pin joint.0.home-sw-in (this is the x home switch) So when pin P4_21 is triggers, it tells remora that remora.input.06 is triggers, which triggers LinuxCNC joint.0.home is triggered (x axis homing pin)

the remora.hal and LinuxCNC do not know if you have an NVEM or an EC300 they do not need to know and they do not care.
