Comgrow Z1 Connection to PC

Hello all!

Trying to get my new(first) Laser Engraver to connect to Lightburn.

I’ve made some progress on my own and via googling, but I’ve hit a wall.

Installed drivers and PC didn’t see the engraver, changed USB cables and now my PC sees that it’s there. However, Lightburn and the other Software that I legit can’t remember the name of will not connect.

Enabled DTR > Nothing
Checked all Baud Rates with and without DTR enabled > Nothing
Uninstalled other software > Nothing
Uninstalled and reinstalled Drivers > Nothing.

Now I’m stuck and here’s what I’m getting in Console:

(Note: There’s WAYYY more of the following in Console than I’m pasting)

I’m about 92% sure that the issue is operator/driver/setting. But I’m at a loss

Waiting for connection…

Update:

Now I’m just getting the G0 Command on repeat in console

The Baud rates to try;

Check latest firmware and CH34x driver
Setup your device as GRBL only.

Attempted a Firmware update.
Indicator Light = Solid Red with no green.
Multiple USB Cables & Ports Tried.

Seeing only repeating G0 Command now. Will not respond to $$ commands.

Try the attached device configuration file (download then drag it into the LightBurn window to install it).

COMGO Z1.lbdev (2.4 KB)

Tried that. I’m still getting G0 on repeat. I’m wondering if the control board is bricked at this point?

If you updated the firmware above 2.0 you might need to change the baud rate to 961200.

Also, tried LaserGRBL. Nothing from it either.
Control Unit has only the Red Light lit solid, no life out of Green.
Firmware update was done off a SD card other than the included one.
Attempted to connect Via Wi-Fi and still no disco.

You might need to contact Comgrow?

Contact Comgrow? Oh you crack me up!

The email they give Amazon for support returns undeliverable. Tried another email off their main website and it’s quieter than a snowy night.

Going to try the firmware for the 5th time for kicks. But I’ve just contacted Amazon and having them send me another one to arrive tomorrow.

seasonally appropriate dig :slight_smile:

Good plan!

Having the same issue, when I update it while it is plugged into the PC it gives this output

G0
G0
The TF card already exists.
Mount succeeded.
Firmware.bin file already exists in TF Card
File opened successfully.

This is with the new 2.3 firmware just wanted to see if this helps with the troubleshooting.

Maybe the solution is connecting without the SD card.

It looks like the firmware is unable to write the “program area” and that is why it failled.

And yes with the sd removed it still doesnt work. Due to that.
