There is also an Arduino Nano controller with GRBL firmware in the cabinet:

Stepper motor information:

  • Holding torque: 1.13nm
  • Voltage per phase: 4.2a
  • Step angle: 1.8° (200 steps per revolution)
  • Angle error: ± 5
  • Connection lines: 8

steps_per_mm = (steps_per_revolution*microsteps)/mm_per_rev

The CNC Mill is currently being commissioned

So we officially started up the comissioning of the CNC Mill on Tursday 8th May. First job was to see what components we have and what the current state of the mill was.

The overall state of the Mill was messy with the current components and accessories all stored in the main compartment. We cleared this all out, and gave the mill a thorough clean.

Next we took a look at the electrics in the back.

These were in a right mess with unshielded wires, and some dodgy epoxied sections for the coolant. The decision was quickly made to strip everything out and start again. Drew logged the wiring locations and traces and then we removed the components.

The team decided to make things cleaner and easier to maintain, to mount all of the electronic components on a board which could be hung on the back wall of the cabinet.

Ryan made the mounting board and the components were laid out and fitted. The board then got mounted to the cabinet for wiring.

Simon has kindly offered to take the lead on the wiring so, we will update as progress is made.

UPDATE 01/08/2019: X axis movement!
