For some engraving jobs, “megabytes” will be on the low side.

One _assumption_ that has proven true, over and over again, is that the laser controller’s USB hardware is borderline inadequate, driven by relentless cost optimization.

In addition, the USB standards were never intended to cope with low-budget PCBs switching high-current lasers using MOSFET drivers and marginal power supplies.

Mash that together with the cheapest possible USB cable and you get all the USB-related problems washing ashore around here.

These resolved nicely :

> I have just purchased a Gweike Cloud RF laser, using with Lightburn. The supplied USB cable works fine but it’s very short. So I bought a nice long one, 5 metres length. USB C to USB A, I use Macs. It’s a good quality cable, but I don’t seem to be able to make a connection when I plug in to the laser and to my Mac? Any suggestions/fixes most welcomed. I came across a really useful post by @BillieRuben who seems to have knowledge of these machines and setting up, any idea Billie ? tia blush

> Hello, I’m a nub to lasers and LightBurn but I have been a CAD operator for 40+ years so I the LightBurn program is not a foreign software to me. I have created a LightBurn drawing that i want to use to test my new laser and figure out power and speed for my laser. When i test my drawing by starting the PREVIEW command, the preview runs perfectly. But, when i send the send the START command to the laser, the laser starts by moving to the first object (a 1/2" diameter circle) to engrave/cut (li…

But that’s not the way the machines start …
