Cant connect Orator LM3 with Mac M1

[ToxicityArmy (Sandro)]

Hello everyone,

I recently bought an Ortur Lasermaster 3.
It works on my Windows laptop without any problems. Unfortunately, I can’t connect it to my MacBook Air with M1 processor from 2020. I have already found a thread about this in this forum and bought the suggested cable (old USB A to USB C adapter that runs on USB 2.0). Unfortunately this has not worked yet.
The following message appears when I enter the command ioreg -p IOUSB in the terminal:

±o Root <class IORegistryEntry, id 0x100000100, retain 29>
±o AppleT8103USBXHCI@01000000 <class AppleT8103USBXHCI, id 0x100000583, reg$
±o AppleT8103USBXHCI@00000000 <class AppleT8103USBXHCI, id 0x100000351, reg$

Is there anyone who has a solution to the problem?

Greetings from Germany

Hello Sandro,

Not an uncommon issue with Apple Silicon portable macs (MacBook air, pros etc)

MacOs will silently fail a USB 3.0 handshake, which it will try with your laser. Even though they have a USBC cable, the Lasers are NOT usb 3.0.

Therefore you must add in between the laser and the Computer a USB 2.0 hub, as cheap and “dumb” as possible.

This will force all the connections through the hub to be 2.0 usb handshake and will - hopefully - fix the issue.

Hello Gil,

i have already bought an old an cheap USB 2.0 connector and it still doesn’t work.
Du you have any other suggestions?

[gilaraujo (Gil Araújo)]

If you have, it does not show listed on the
ioreg -p IOUSB

Therefore, it might not have a USB controller chip inside.

Can you take a picture of it and or retry the ioreg -p IOUSB

Hi Gil, thanks for the quick response.
This is the Adapter I use and it was already connected as it typed in in the terminal

[gilaraujo (Gil Araújo)]

That is not a Hub as such, is a simple cable converter.

You need an actual USB Hub 2.0

Hello Gil,
I have purchased a new adapter and the software now recognizes the laser. Thanks for the tip.
Now I have the problem that the console indicates that there is no connection (waiting for Cennection) . Can you help me with this too?

[gilaraujo (Gil Araújo)]

Please, remove ALL the devices

Manually add it as GRBL, not GRBL LPC or GRBL M3

Are you Auto Detecting them?

Delete them all - Import - use this LBDEV I am sending
OLM3.lbdev (3.0 KB)

Hi Gil,
Ive been auto detecting them.
I deleted them and imported your file, but it still says waiting for Connection.
Do you have any other suggestions?

[gilaraujo (Gil Araújo)]

Can you confirm you are connecting to the correct port

See if you have any other serial ports on the Drop Down Menu in front of Devices button
