Go through this guide: Limit Switches - Diode Laser Wiki

Do NOT flash the firmware when adding limit switches. It caused many issues.

Thanks a lot, i’ll check it now.
Now, i want back and i flash original sculpfun s9 software, and Y and X motor axis wont work.
Its possible the motherboard damage after i flash it?

No. But you might have selected the wrong firmware version. The S9 has many different mainboards used in different years. What does yours look like?

5

I install DLC32 normal version from sculpfun download center. I dont know that this software are installed before i flash it.

And MKSLaser Tool is good for flashing?

6

You can use either MKS tool or Sculpfun tool. They are the same.

Okey, thanks.

You recommend some firmware? this DLC32 is bad, and Y and X motor wont work, even i start burn or i frame shape in lightburn. everything in console is work, status machine are busy and program shows time to end laser cut, but laser head wont turn.

Next, can you tell me about this value?:

You recommend some value for instal firmware on sculpfun s9?
In video from sculpfun chanell, i see that firmware installed with BAUD 115200.
Can you explain me please, what this changed?

Before i start setup LIMIT SWITCHES with your guide from Laser Wiki, i must set up machine to latest work firmware.

And of course, thanks a lot for support :slight_smile:

Show a picture of your mainboard, then I can tell you the correct firmware version. The S9 is available with 4 different mainboards and each of them has a different firmware. The values to be used are explained in the wiki as well:

Looks like an esp32 processor.. sure you got the right firmware?

:smiley_cat:

No, im not sure. That why ask about it on forum :slightly_smiling_face: i installed dlc32, what i post few posts ago, and machine crashed.

@misken knows these machines, I do not. Suggest you look for the proper firmware.

Good luck.
