Remove Firmware

Hauke · November 19, 2022, 6:33pm

The image you show which lists the three files ending on .json, .db and .lock, I see when no toolhead is connected. In that case, also the Start-Screen does not list any connected devices (usually it lists the toolhead, for laser the camera, and if you have, also the enclosure, stop button etc.). Can you confirm that your Start screen is “empty” in that sense? If so, your problem might be as simple as the toolhead cable broken. Or, worse, the controller might have a broken toolhead port. To check this, plug the toolhead cable into the Addon 3 port (just below the toolhead port). If that changes things back to normal, that’s a strong indication for a broken port. In that case, acquire a new controller via Snapmaker support.

The dot was yellow

I done what you asked went through all items and nothing changed.

When I go to open a cnc file its a no show again, I only see my download firmware file. Its strange when I have my cnc module installed and will not see cnc settings at the bottom, I see printing heat bed settings and nozzle. I should see cnc speeds. I need this there are times when I manually cut wood holes on the back side of my projects.

Question I have is the controller the brains for Snapmaker or is the vertical member with all the connectors the brains? If its the controller can this be sent back to Snapmaker for repair or replacement?

How do I go about having this done? If you feel you can fix it I can send it to you for repair and I will pay you for the repair.

Like I mentioned before everything worked fine until I purchased a spare cnc module. I installed the new module it asked for update I updated via wifi and then the problem started. I always updated my modules using wifi.

The controller is the box all the wires attach to, yes. You can either email snapmaker support and request to purchase a new one, or order third party such as 3DJake.

Hauke,

You are the first one to mention .json, .db, and .lock. What is this?

I moved the toolhead cable no difference, it will home it will move. When I go to into the usb you can see firmware download folder no, cnc files

I went through changing the firmware no results, I went through removing firmware no results. I tried about everything I can do with help from others, no results.

When I go through installing firmware my low power laser light will stay on.

This all started when I purchased a backup cnc module. When I tried to run the cnc up came install new firmware, I did this by installing by wifi, that’s when my problem started.

Question: Is the controller the brains for Snapmaker or is the vertical member with all the connectors the brains? If its the controller can I send it back to Snapmaker for repair or replacement? How do I go about having this done?

Skreelink,

Do you think this might solve my problem? Should I also get a new controller? I will buy both if necessary.

I refer to this image you posted:

Here you expect to see the CNC files, but you see one .json, one .db and one .lock file. This is the same for me when I start my Snapmaker with no toolhead attached. On top of that, with no toolhead attached, the start screen shows an empty space:

If you have the same, my guess is that your toolhead is not recognized. Since all of your toolheads are not recognized, I’d suppose that either the cable or the controller is damaged. Since you tried another port, my bet would be on the toolhead cable. Perhaps you bent a pin when you plugged in the toolhead cable at some point? It should look like this:

Perhaps one of the six thinner pins is bent? If so, order a new toolhead cable - it’s 8 € or so.

Sorry, did not answer this one: The controller is the thing with all the cables going into, and it is the part that controls the motors, the toolheads and the heated bed. It receives the instructions via GCode either from the serial port or from the touchscreen and runs a modified version of Marlin 3D printer firmware.
The touchscreen is the user interface, handles the USB port, the WiFi-connection and the laser camera, and it runs Android. When you use the Jog interface or run a job from the USB stick or via Luban (either by sending a file or running the job directly), the touchscreen sends commands to the controller, which then moves the motors, powers the laser etc.

Hauke,

Mine looks good I am going to order one

Thanks,

Skreelink,

I will order one if and when I solve this problem I will let you know something. I appreciate all your help.

Hopefully it works out and you get back up and running.

It’s been a while, but I believe that updating firmware for the different modules needs to be done by usb stick, not over wifi. Done separately for each head.

Should I shut down Snapmaker between each module upgrade?

Yes you have to unpower the machine between because it is not recommened to unplug any cable while operation.

Hi there - Wanted to follow up on this - i still am having the exact same issue as timsco60.

I recently (yesterday) upgraded firmware to my cnc module or my whole snap maker ( i cannot remember exactly)

Since then, my snapmaker can recognize all my other modules, except the cnc.

I have downgraded firmware, and made sure to upgrade all other toolheads.
the cnc is the only piece that does not seem to work

xchrisd · November 29, 2022, 8:31pm

Maybe this helps:

sbrehmer · November 29, 2022, 8:55pm

This is my current set up

firmware version - Snapmaker2_V1.14.3 -looks like latest
Touchscreen - V1.14.2
Controller Version V4.4.17

I am having trouble finding the latest firmware is for the touchscreen and controller.

sbrehmer · November 29, 2022, 9:05pm

I connected via serial and did a M1999 This is what I was returned.

The only issue i can see is that it has no module in can1… which i can confirm the cnc module is plugged in right now.
