About GRBL System Q-1: What should I do if the driver and software cannot be installed successfully?A-1: First install Win7/ win10 under the support system, the re-install or exit th anti-viirus software and re-install. ( We cannot guarantte 100% support for win10. If the user cannot install the driver on the win10 system, please contacte uss to solve it. ) Software: Grblcontrol Format flies that support Grblcontrol engraving: Support G-code files of nc, ncc, tap, txt Format flies that support 2-axis engraving: Support nc, ncc, tap, G-code, ngc, png, jpg, gif, svg GRBL1.1 CONTROLLER BOARD Updated Version New fuction : Add emergency stop port and X/Y/X axis limit switch portAdd the power switch button, simple operation, more safety in the process of using the machine.Enhanced spindle drive, can support up to 20,000 rpm spindle motor.Add the outer casing, not only protect control board in transit, to avoid short circuit problem during use.Cancel the drive module,use integrated imported stepper motor drive,with short circuit protection,and integrated heat dissipation aluminum alloy. Improved USB interface: The original USB interface is patch soldering, transport collision and improper use, easy to drop, now changed to plug-in, very strong. The spindle drive increases the optocoupler isolation, which makes the control board generate less heat, and the spindle speed adjustment is more linear and safer. Add offline controller recognition,can insert offline modules and computers at the same time. Offline controller will automatically identify if there is computer control. Add the low noise fan port to force heat dissipation.
