Trying to repower some machines. Want to use a control board with integrated stepper drivers, so it will fit inside the machine. That rules out using the Remora compatible ethernet boards.

There isn't a whole lot of room. Not sure yet if there is room to fit a skr and raspberry pi. Having the raspberry pi inside the machine isn't ideal. Would need a separate pc to use for remote desk toping to it.

Was planning on using an Intel NUC. That's much more powerful than a raspberry pi. Also has a proper enclosure.

Guess if I had to I could mount the raspberry pi on the back of the monitor like I was going to do with the NUC. Then run the spi wires to the machine. Going to need a bulkhead connector anyways. Wouldn't really matter if it's ethernet or a 6 pin connector.

With another machine I used a Genmitsu usb Mach 3 board. It's a compact controller like what I'm looking for. Unfortunately that has been discontinued, so I'm looking for an alternative.

The other option is to use the skr as is, or similar grbl board. The ones for routers are much smaller. Tried Universal Gcode Sender a few years ago and didn't really like it. It worked, but is very limited compared to Linuxcnc or Mach 3.

Thanks that clears up most of it. On the 1.4 board there's pin p1.31. What would that connect to on the w5500 board? In the video there's a power supply going to the w5500 board. Does it need 5v, 3.3v, or both? The documentation shows that it's possible to power a raspberry pi with the 1.4 board. Is it possible to do the same with the w5500 board? Looks like there's 5v there.

   

Raspberry Pi 4B running Gmoccapy 4.9.4 without any significant issues on a 3-axis turret mill.

CamBam used to produce 3D MOPs for cast iron model locomotive wheels.
Camotics and NCViewer used to simulate the GCode files produced. 

But, as we all know, issues do arise that need review.

NCViewer displays the GCode file and a 3D representation of the paths.
It includes an option that shows each GCode data point in the 3D display as a GCode line is highlighted.
The reverse does not work, selecting a data point does not highlight the equivalent GCode line.
 
Looking for suggestions on how to identify a GCode line when a path/point is selected on a 3D path display.

I searched through the documentation before starting this thread. That only shows how to wire it to a raspberry pi.

As I said at the beginning I do not want to use a raspberry pi. I want to use a w5500 ethernet board. Then connect with a pc. Like shown in the demo video.

i just order some shift level converter can use whit rpi gpio can make out 3,3V to 5V all gpio pin, and then one optocoupler board can add rpi inputs safe, 5V in to 3,3V to rpi,
then can add all STEP,DIR,Enable pins traight to drivers DM556 i used normal,
but problem is were have image can use rpi3, not need be fast, this come only dovetail jig tool make long plank top dovetails not more, no need be full cnc, working area has need only XY axis, what has moved Z axis to 90 degree and spindle have horicontal not normal vertical system. simple hardware but image need old rpi3 board first.

forum has made help any peoples how do linuxcnc to raspberry etc other linuxcnc problems, forum need help and teach all newbie how make somethink. my own language not have forum and maybe not many peoples who can help newbie user, Finnish language need be. but i believe not have many peoples. i has build many many cnc machine before but now think need one small simple dovetail tool made whit my old rpi3 board but search google lot and not have any image what can use, all has only lot problem code and install and what have kernel compile or what need doing not understand and know what need doing. need only image what can install to SD card simple not more need doing. same than normal computer can install linuxcnc 2,8,4 my daily used cnc machine, easy simple fast install and setting workig. no problems, why not has made normal image to SD card and can use similar than computer this working. not big job all computer engineer gurus and nerds. all not have nerd and understand linux code but lot have peoples who want use rpi3 cnc.

This is getting silly, 3 times you post, I did try to help you with your first post. You didn't say you were using RPi3B to begin with. I did politely ask what your native language was, so we could find someone to help you, as it quite clear English is not your first language.
First of all I think you need to find some Linux info in your own language, this forum is not here how to teach people how to use Linux takes way too much time. Anything Linuxcnc we can help.

what this all code have ??? not understand anything. have linuxcnc image what can add to SD card and run rpi3 ready to use, i not understand this all secret code anything, what need doing or how doing and were doing.

need only image who working and can run rpi 3 board and connect stepper drivers DM556 to rpi and run nema 23 motors. whit linuxcnc.

this link has only pi 4 images, not any oi 3. what need doing can use pi 3 and linuxcnc, what is patch and how need doing, or what need doing, not understand , ready to install pi 3 image only need how need patch or what this mean and how change kernel if need no understand anything linux and code, secret engineer language all.

not understand what is compile and how need do ? or have ready to use image to rpi3.
i looking make rpi3 linuxcnc small cnc my son.
or how kernel need use or how can change kernel or what need doing. too hard all linux system but have only what can use good whit linuxcnc and rpi3 board. not want buy old computer and paraller port use this.

I've just been down that road (at least one of them):

I wonder, is there a Raspberry HAT that can direct interface with a stepper driver ?

Hello friend, I will try to help as much as I can.
First I would like to ask what language is best for you ? I am asking this as I can only speak English. It is my hope that there maybe someone that speaks your native language and maybe able to help.

For the image the most recent can be found here:
forum.linuxcnc.org/9-installing-linuxcnc...mages?start=0#338181

Byte2Bob help can be found here:

I hope this is a start. I will do as much as I can to help.
All the best
Rob

you can use this bob directly on the RPI GPIO's:

www.amazon.de/DollaTek-5-Achsen-CNC-Brea...reiber/dp/B07PNDXZQK

only need to build an adapter cable, there are no 5v comming out of the bob on the db25 side, no risk to damage the gpio's.
