QB2 CNC Maintenance guide
It is recommended to visit this guide immediately after positioning your machine
and setting it up. It is also recommended to periodically visit this guide to ensure
smooth operation and a long service life of your machine
or if something isn’t
quite right such as cuts not coming out right or Z axis depth inconsistent
.
1.
Check ALL of the nuts and bolts on your machine.
Visit all of the nuts and bolts on your machine. You will need a 2mm, 2.5mm, 3mm
and 4mm allen keys and a small flat blade screwdriver to check every connection. Test
each bolt and tighten them if they are loose. This includes the green connectors that
join the wires together on your limit switches and stepper motors.
IMPORTANT: When tightening any allen key bolts it is recommended to use a solid
allen key end NOT any ball end side of an allen key or you run the risk of stripping the
bolt heads.
2.
Check to make sure your gantry is square.
It is important to ensure your machine frame stays square. Use a tape measure or
ruler to make sure both sides of the machine are equal distance from the front. To do
this, measure from the gantry side plate to the front plate. Repeat the same process
on the other side of the machine and record the results. If one side is more than 1mm
out from the other side you need to manual turn the lead screw on one side of the
machine until it is within 1mm of the other side. You can look at repeating this simple
process daily or every 1-2 weeks. The more frequently it is performed, the better your
machine will operate.
