6.1 Common Trouble Shooting Questions
The problems and answers below are the most common issues that we have received in
our experience. If you are having an issue, before contacting us, we recommend reading
through this beforehand.
Problem - LED Volt Meter is not displaying anything.
Check it is wired correctly - if it is wired correctly please email us asking for a replace-
ment and one will be sent out right away.
Problem - The voltage drops on the LED Volt Meter when turning on the
machine.
There is a switch on the side the power supply to change the input voltage. Make sure
this is set to match your countries voltage supply.
Problem - Motors are not moving when issuing a jog command.
Check $4 = 1.
Problem - A motor is juddering, but not turning.
This is mostly due to either the motor being wired in an incorrect color order, or there is
a loose wire connection.
Problem - When issuing a Y-Axis jog command, it just vibrates but doesn’t
move.
This is a common error on a belt drive machine, as the motors have to be turning in
opposite directions. Go back through section 6.1, and specifically look at the top right of
the image regarding belt drive wiring.
Problem - Soft limit errors every time when running a file.
Check $130, $131, & $132 are set to the correct value for your size machine. Make sure
the CAM program is setup in millimeters. Make sure that work zero is set in a position
which allows for enough travel on each axis to complete the job. Most CAM programs
have a safe Z Height setting, so make sure there is also enough positive Z travel from
work zero to accommodate this. Wherever the zero position is set in the CAM program,
you need to home the machine and then move the tip of the cutter to this position, and
press the ‘Reset Zero’ button
Problem - When cutting, circles are not circle.
This is most likely because either a coupler or pulley is slipping on the motor shaft. Check
screws are tight, and one of them is on the flat portion of the motor shaft.
Problem - Machine goes randomly off course mid job or machine stops.
Electrical interference is a common cause of this problem. Make sure the USB & router
cable are outside the drag chains, and sleep/low power mode is turned off on the com-
puter. Carry out a long dummy run with a pen (i.e no router and no dust extraction) and
see if the problem persists. If it still persists, try another computer.
Problem - Machine was working correctly, now suddenly behaving strangely.
