The spindle continues to rotate when the machine stops It should then move freely across the axis. Move the spindle mount all the way to the left by turning the threaded screw by hand and tighten the left hand screws, move the spindle mount to the right in the same way and tighten the right hand screws. The Y-axis bearings work perfectly for reference.Ĭheck the alignment of the guide rods and the threaded screw moving the axis, check the coupler between the stepper motor and the X-axis threaded screw is correctly aligned and slacken the screws holding the guide rods. When I test slide them with the shafts outside of the machine there is a ton of friction on them. I am having an issue with the X-axis linear bearings, they are binding extremely bad causing the machine to catch and jump at certain times. The offline controller and the USB cable cannot be connected at the same time. If the USB cable is connected correctly, the 5V indicator next to the RESET key will light up. Have one can’t get to work don’t know if the USB cables connected correctly. If the offline control module failed to control the machine, we suggest that you upgrade the firmware for the motherboard.
Then use the offline control module to control the machine. Please check whether the USB port of the motherboard is loose or not. I’ve tried restarting, reinstalling the grbl software, and tried the reset button on the control board. The machine doesn’t show up on the com ports at all in either computer I’ve tried. Now no matter which usb port I try it will not connect. I have since tried it with two other computers and the offline controller which had worked fine when testing it earlier. I was able to assemble the machine and everything was working fine, but then in the middle of the sample carvings the machine lost connection. Make sure that you have installed the driver and selected the correct COM port. This is Windows saying it cannot connect to the router. When trying to connect, I get the “serial port error 1: no such file or directory”.
