Laser Cutter Training

This page documents the process for being trained on the Laser Cutter.

Summary

Training takes place in three main steps:

  • Group Training of up to 4 members, going through the equipment and how to use it (~1hr)
  • Individual Training Task, where an individual member is set a task to complete to prove and improve understanding (~30min each)
  • Project Oversight, where more experienced users oversee the projects being undertaken when cutting (first 2-3 projects)

Training on the Laser Cutter is run by the Laser Cutter Owners. The Laser Cutter Owners are a group of people responsible for maintaining and training on the laser cutter, and hence have been trained to train, and trained to perform the weekly and monthly maintenance on the laser cutter.

Booking

Laser training is by request. Any training sessions will be advertised on Facebook/Twitter

Training Cheatsheet

The training structure and prompt sheet. Please note, this is used by the Laser Cutter Owners as a prompt to ensure training is executed in a consistent and complete fashion is included on this page; this does not constitute and is not a substitute for the training itself.

Group Training

The group training introduction structure, suitable for 1-4 members at a time in a 1 hr session.

Introduction of main components

  • Laser
  • Cutting Mechanics
  • Water Chiller System
  • PC/software
  • Materials (what it can cut, supply)

Laser Hazards

  • Process and progression for normal operation failure (fire) - pause, open, move, CO2
  • Process for abnormal operation failure (mechanical/jam) - emergency stop, open, move, CO2
  • Ensure confident of process

Checks for everyone to do

  • Check in use, looks ok
  • Check water bath, temperature

Powering Up

  • Turning on Laser, what to do if doesn't power up
  • Turning on PC and starting software

RDWorks Project walkthrough

  • Package function, drawing, import file types
  • Bed dimensions
  • Paths
  • Green Square
  • Layers and colours
  • Through cut, surface cut, scan and engraving, speeds and strengths
  • Various steps to build up design (shapes, text, uniting, layers, alignment, scaling, layers)
  • Job ordering
  • Saving
  • Download with "Current Position"

Laser Operation

  • Lid
  • Control panel, escape
  • Moving head XY, indicator laser, origin
  • Moving Z
  • Focus
  • Start position and test
  • Start, pause and emergency stop function
  • Do job, pause/open lid, restart

Power Down

  • Switch off laser
  • Switch off chiller and fans
  • Clean any residue from the bed or bottom tray
  • Close lid

Individual Training Task

The individual task to get familiar, prompt questions and check understanding:

Task

  • Make a simple item
  • Should use a selection of full cut, surface cut and scan/engrave features
  • Should demonstrate all steps, size, appropriate ordering, positioning

Steps

  • Set individual to work, don't prompt but do answer questions (or pose if needed)
  • Talk through design once done, question/check things etc
  • Proceed to lasering (watch carefully all steps)
  • Ask to stop job/restart, question escalation process

Assuming all ok:

  • Get them to read the health and safety notes about operation and materials
  • Add to the trained member list!

Project Oversight

For next 2-3 projects, ensure member will find another more experienced trained user to support them (second pair of eyes)
