Trouble homing makelangelo 5

[tjhawkey]

Hi Dan, I’m getting back to work with my makelangelo 5 and am suffering some homing problems similar to others I’ve seen here.
1) I have the 400 step motors — my config.h is correct, but I have to confess that it’s not clear to me from the instructions how to set up a local config.h as suggested in version 9.2
You said this, but I can’t parse what that means exactly (sorry!)
copy ./presets/makelangelo5.h? to ./local_config.h and it should work.
2) Homing goes to the limit switches, but then stays there without moving up. That makes all following actions fail.
3) The makelangelo 5 settings window in the software says the belts are 2mlong, but they are really just about 1 meter. Doe that dialog box mean anything? The main firmwre file has lines that say 1011 mm

I have not yet sent D11, but I can try that. How does that relate to the settings in the firmware?

Also, software 7.21 works on my win 10 machine, but 7.23 starts with the picture, but then crashes with the message “an unexpected error occurred…” Any suggestions?

Thanks!

Du-oh. I still don’t understand the local config guidance, but I just realized that “find home” is sort of a misnomer. “Find limit switches” seems like a more accurate description.
After I “find home” I have to “go home” before starting a drawing. That’s a little different than previous behavior and it faked me out.

copy ./presets/makelangelo5.h? to ./local_config.h and it should work.

That is correct

“find home” is not “find limit switches”

True…. in the M5 my default is that the home position is also limit switch position. That is not the cartesian origin (0,0). Someone recently contributed a way to set your own home position and that may be part of the confusion. I like it bottom center because it’s reachable on all sizes of machine. Your mileage may vary.

Can you run the 7.23 from the command line? It’s probably spitting out an exception that is not logged to the file (boo). That exception will tell us more about what’s going on.

Also feel free to join our discord to talk live, it can often get faster response times.

re bonjour

après investigation

je suis sur Makelangelo 7.2.4.0 et Makelangelo-firmware-9.2.0
rumba et DRV8825 avec
#define MICROSTEPS (32.0)
#define MACHINE_STYLE POLARGRAPH
#define MOTHERBOARD BOARD_RUMBA

find home ces bien un G28 = il fonctionne

Go home ces la position du porte stylo a 20 cm en dessous du centre = les moteur tourne tout doucement (il avance au millimètre)

il avance correctement pour le G28

désoler le le dérangement
