When we want to transfer g-code program,we got a SteelTailor “USB CONNECTION ERROR”.

When you got this message, SteelTailor need some information and SteelTailor suggest you check these:

1.Is the USB flash disk the one we sent with SteelTailor portable CNC cutting machine?

2.Did the machine read USB flash disk well ever, before this happened, what did you do to the USB disk and the SteelTailor portable CNC cutting machine?

3.Is your USB disk in FAT or FAT32 format? This is import, SteelTailor suggest you format your USB disk into FAT immediately and then have a try.

4.Open the housing of the central unit and plug the USB flash disk directly into the controller. And you can see there is an USB port at the back of the controller with a cable, unplug the cable.

5.Sometimes computer virus is the reasons of the failure, so we suggest you format your USB flash disk on other computer and have a try.

6.Your USB flash disk is damaged, change other USB flash disk and format them into FAT then have a try.

7.Test the Power voltage of the controller, see if it is too low or too high, it should be 24VDC.

Make sure all grounding terminals are grounded.
