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.

Docs on github linked on that topic, at the very start of it
remora-docs.readthedocs.io/en/latest/har...ring-to-raspberry-pi

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 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.

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 ?

Thanks

Some advice regarding chatgpt and AI in general for help. Currently it is not a good idea asking about Linuxcnc, many many times it gives answers that make no sense and will not work.

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:

Byte2Bob help can be found here:
forum.linuxcnc.org/9-installing-linuxcnc...aughter-board#339613

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

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.

NOT can found, no have, only can use paraller port hat and paraller port breakoutboard, if want rpi use stepper drive direct need voltage level shifter board, 3,3V to 5V 8 pin converter, rpi use 3,3V and convert output can use 5V stuff, etc, stepper motor driver, step and dir pin, and enable pin. and same can bi -directional board use input too 5V sensors,limitSW etc convert to 3,3V and use whit rpi. same output relays etc, cn use gpio pin 3,3V convert to 5V and then use trnsistor who connect to relay on/off relay. gpio not handle lot current about 2mA out and in little more, or burn input/output port. thats why need converter and optocoupler to input current resistor need too, stuff not broken rpi. and shift level converter and resistor output no burn output pin, if have lot money waste buy ower price protoneer rpi cnc shield 100€ horriple price, or cheapen option rpi paraller port hat 35€ and cheap chinese 10€ breakoutboard. i think have possiple use shift level converter to input/output gpio pins and optocoupler cheap in-out system direct to driver and all limit,home,probe,etc inputs, opto input pins and shift level converter output pins, i hope working , i need test if has order all parts, but i not understand what software need do, image were is linuxcnc and how working whit paraller port hat if use, or what need hal file doing or other, programs and code not my job ,not understand anything.
