CNC Maintenance Tips
Maintenance tips shown on this page are from the Nomad 3 “Getting Started Guide”. Other CNC mills may have different maintenance requirements.
Recommend lubricating your X-, Y-Axis rails approximately every 50 hours of machining, or when you start to notice a buildup of dust and grime. Also recommend lubricating your Z-Axis every 6 months. Other than the occasional lubrication, your Nomad 3 is maintenance free!
Lubricating the X- And Y-Axis The only oil we use and recommend for lubrication of the Nomad 3’s X- and Y- rails is Super Lube Synthetic Oil with PTFE. It’s available from Amazon in various container sizes and types as well as some sewing machine supply shops.
To lubricate the X and Y-Axis:
Move the X or Y-Axis to one extreme.
Wipe a thin layer of Super Lube onto the rails.
Then, jog the lubricated axis back and forth a few times. Most of the oil will be pushed aside by the bearing seals but some of it will get in there, and that is enough to do the job.
After you’ve jogged the axis back and forth a few times, wipe the remaining oil from the rails so that it doesn’t attract dust.
To lubricate the Z-Axis:
Put a quick coat of synthetic oil (such as Mobil Vactra No. 2 Oil) on the linear rails and leadscrew.
