How to setup bltouch and Z touch plate for 3 in 1 cnc.

@Ambros two folders in sys is correct. But you still need a config.g in sys for startup. Something like:

M505 P"3D printer"
; M505 P"CNC”
M98 P"config.g"

You can comment/uncomment the M505 commands to have one or other active at start up.

You can also create two macros in the macro folder to switch between the two, similar to above.

Make sure you keep the firmware binary files and iap4e.bin file in the sys folder for firmware updates.

@droftarts An apology for my dumb question. what you are saying is that after making two different folders of 3d printer and CNC and putting only config file. In the main sys folder, I need to create a config.g file and put the code.
M505 P"3D printer"
; M505 P"CNC”
M98 P"config.g"

And that's all.
One more thing I wanted to know that if you take a look on homeall.g, homex.g, homey.g and homez.g file and few more files as well they have code written inside them. But since in my CNC I am using a limit switch to zero the z-axis and in my main folder, the file homeall.g and homez.g doesn't contain any parameter to use those limit switch. Did i need to put any separate file for them? Or I need to put all the files inside those folders which I created named CNC and 3d printer and in the main folder, there is only custom config.g file. And there are only 3 files shown in main system folder CNC, 3d printer folder and a config.g file and that's all I need. Which one is correct. down below I made a file structure in the main folder kindly suggest which one is correct.

File structure in sys mains folder
3d printer(with all the files)
CNC (with all the files)
Config.g(which created custom having those three parametre)

or

3d printer(only the config.g)
CNC (only the config.g)
Config.g(which created custom having those three parametres)
bed.g
deployprobe.g
homeall.g
homex.g
homey.g
homez.g
pause.g
resume.g
resurrect.g
sleep.g
retractprobe.g
stop.g
tfree0.g
tpost0.g
tpre0.g

@Ambros said in How to setup bltouch and Z touch plate for 3 in 1 cnc.:

File structure in sys mains folder
3d printer(with all the files)
CNC (with all the files)
Config.g(which created custom having those three parametre)

This one is correct, except that you also need the iap file in /sys in order to upgrade the firmware from DWC. New firmware files must also be uploaded into /sys, not into one of the subfolders.

@dc42 Sir now with that file setup the machine is able to load the printer settings, but the problem is that when I use the macro to use CNC files I got an error and it says
macro file config.g not found.
can you please tell what wrong I did. The macro file name is cnc and inside that the code is
M505 P"cnc"
M98 P"config.g"
One thing I noticed in the 3dprinter folder that there it a folder created by itself named cnc" and this is the correct notation I wrote. And inside this folder, if I open again and again seven times then a file name config-override.g shows and it says that its a computer generated file. But if I gave cnc to first problem it says macro file config.g not found, even though it still present inside that folder with everything properly written inside them.

@Ambros In the sys folder, you should have two folders; "3d printer" and "cnc". You should not have "cnc" in the "3d printer" folder.

To change from 3D printer to cnc, because you have already set the path to "/sys/3d printer", you need to give the full path to "cnc". This is in the macro only; you don't need to do this for the startup /sys/config.g.

For the cnc macro, try:
M505 P"/sys/cnc/"
M98 P"config.g"

For the 3d printer macro, try:
M505 P"/sys/3d printer/"
M98 P"config.g"

@droftarts @dc42 Hi dear, you are correct about the macro and now I am successfully able to switch but the problem is that when I switch to 3dprinter it's accomplished without any error but if I switch to CNC it again says
macro file config.g not found.
So to sort out this problem I flash the sd card and upload the config files of both cnc and 3dprinter. but error remains the same (able to switch to 3d printer but not to the cnc)
Then I put the same types of files in both the folders(I mean the 3dprinter files which are successfully loaded by the duet) but issue remains the same.
I also change the folder name to something different like a router, cncrouter etc. but the issue remains the same.
I also give first preference to cnc in config.g file which is
M505 P"cnc"
; M505 P"3dprinter"
M98 P"config.g"
But same issue again.
Dont know why it wasn't able to load that second folder files. It always says(macro file config.g not found.)
During all these changes I also change the name in config.g file which is in sys folder and names in the macros as well, but still facing the same issue. The machine have no problem in switching back to printer mod but during the cnc mod, it says that line and I wasn't able to do anything.

I am not able to understand if two folders have same files inside them then why it gives error in one case and not in other.

[droftarts]

Maybe a space, or extra invisible character, on the end of the cnc folder name on the SD card? eg "cnc "

[Ambros]

@droftarts so besides that reason there is no other reason for this error because after reading your message I double-check and still the same problem.

[droftarts]

@Ambros Can you post a screen shot of the /sys/ folder from DWC? And showing contents of /cnc and /3dprinter? And post the EXACT macro files and /sys/config.g (copy and paste them from DWC)? I can't tell where the error is from your descriptions.

Ian

[Ambros]

@droftarts So here are the screenshot of the different directory

[droftarts]

It's the curly quote on the cnc macro:

Change it to a straight quote "

I can't see anything else wrong. Does this fix everything?

@droftarts You are a true master and I am really thankful to you, Can't able to express my feelings. You and all the people helped a lot and huge thanks to all of you. Especially you and dc42. Extremely happy now.
