CNC Table Step by Step by Jake
- turn on PC
- turn on CNC
- turn on dust collector
- put material being cut onto table
- turn on vacuum table a few minutes prior to making your cut. I've always tried to allow sometime for the table to flatten out.
- download G-Code being cut
- Open G-Code in text editor
- verify G-Code has the spindle turn on command (it will always be within the first 20 lines of code)
- modify G-Code z heights according to material thickness (test cuts are done in a single depth pass, verify depth on CNC log book)
- Open Mach 3 on computer
- disabled soft limits and move the machine on the z-axis
- calibrate all machine coordinates
- > Reference All = Machine Zero
- > Zero All = Job Zero
- re-enable soft limits
- import g-code being cut
- Open Mach 3 config and set safe as height to 70 (this is required ever time mach3 is opened with a file for the first time)
- verify correct tooling is in the machine per the cut log book (common use tools are below the keyboard for the computer)
- zero your job coordinates
- set your machine spindle speed per cut log book
- set your machine feed rate per cut log book
- manually jog machine away from each work 0 point
- press go to job zero button (this seems to prevent an issue with the machine loosing its job zero position)
- set feed rate at 1%
- initiate cut and watch spindle speed on the CNC's display, once the spindle is up to speed increase the feed rate to 100% (or ehat ever is required to reach the desired feed rate according to the CNC log book)
- monitor CNC cut until cut is finished
- type G28 command in console to home the machine
- shut down all systems once all cutting is completed
