I am running a MacBook Air, Catalina 10.15.7. I am having some problems with Lightburn recognizing the Genmitsu L8. I am working with SainSmart as there seems to be some issues with the CH34X USB to Serial driver installation and so I am just wondering if anyone else has been down this road. I think the problem is more on Sainsmart’s end but thought I would post the question here as well.
MAC OS needs no drivers
Probably you are on M1 chip?
Check these
Thanks for the quick reply. I have the Intel Core i7. I ran into a similar issue with my CNC router. Some said to load the USB driver file others sites said no. I ultimately deleted the supplied drivers and the CNC router communicated just fine. I just did the same thing this morning. I unloaded the CH340 USB to Serial driver but Lightburn still did not see it. One thing that does trouble me is in the bottom righthand corner of the Lightburn screen where you can find “devices” my only options is “cu.bluetooth-incoming”. That to me does not seem correct based on my CNC router configuration.
you can check if your usb serial is being detected
Open terminal
Type
ioreg -p IOUSB
paste result
you might want to do this on several iterations of usb adapters and or hubs
Here you go…Dons-MacBook-Air:~ ldontyler$ ioreg -p IOUSB

from what i can see, but you can do a double check by retriggering command without machine on, is not being detected
so is cable/Hub issue.
Typical issue on M1 chips
I just dealt with this in another thread. Same issue. Easy solve.
M1 chip looks for USB-C first. If it does not find it then no go. Go to Best Buy and get the cheapest (oldest) USB hub you can. It will force the M1 chip to go beyond USB-C and recognize the machine.
The first one I sent was with the laser off. Here is with the laser on. What i find interesting is the last line clearly shows a RGB camera which makes me think it sees the camera mounted with the laser. I may not be using the right cable…

I am not particular on the IO of this machine but, i would think is 99% sure a serial coms issue
Easier to diagnose if you have a different pc/Mac you could run a sanity check with
not the wrong cable… but i will try the hub mentioned by Joe Glynn
crazy…but seems to have worked. It now sees the laser…can’t get it moving yet but i bet i can figure that out…thanks for all the help
if you read the post i set on 1st answer there is an explanation why
