Problem with my china 3018 cnc

Most of those Chinese CNC machines use a CH340 driver that will either be on the CD or you can download it.

They also prefer USB 2.0 ports but will occasionally work on USB 3.0.

Be careful of the Chinese software as some of it is blatantly illegal copies.
You will also probably find the CNC board supplied has GRBL 0.9 and I found it better to upgrade the firmware to the newer GRBL 1.0

If your has the 3d printed spindle holder you are strongly advised to use the machine itself to make a spare one of of hardwood or if you can find the file get somebody to make a spare on a 3d printer but with much more filler section as they are quite weak and break easily.

Most times the spindle supplied is only any good for very light cuts < .5mm and has a lot of Z drift +- as much as 1.5 mm.
