Pease talk to Tom Judge before tackling any items on this list.


Todo List

  • Install limit switches
  • Work out touch off wiring
  • Re-wire control box safely
  • Build PC workstation
  • Switch Plasma cutter outlet for a single phase 220 rather than three phase
  • Air lines
  • Order water table
  • Plumb water table
  • Plumb new air lines
  • Install Long axis drag chain
  • New PC
  • New PC/Stepper interface module
  • Software licenses

Future Items

  • Tube attachment
  • scribe attachment


Required parts

  • Smoothstepper Ethernet


Automatic Z zeroing

Ohmic sensing

Pros:

  • Simple wiring torch needs a few accessories to make it work correct
  • Pre-build modules avaliable relatively cheeply ($75 candcnc)
  • What everyone else does

Cons:

  • Un-reliable with the water table


Touch off

Pros:

  • Simpler that ohmic

Cons:

  • Err?

Torch Consumables

The torch is a T45m hypertherm machine torch.

Standard

  • Deflector P/N: 2206732
  • Retaining Cap - Ohmic P/N: 220719
  • Nozzle P/N: 220671
  • Electrode P/N: 220669
  • Swirl Ring P/N: 220670

Fine Cut

NOTE: These parts are for a t30 unshielded torch, they are compatiable with the T45m when it is run at a setting lower than 30A and cutting materials thinner than 3/16". Ohmic sensing will not work with these parts installed.

  • Deflector P/N: 2206732
  • Retaining Cap - Ohmic P/N: 220483
  • Nozzle P/N: 220480
  • Electrode P/N: 220479
  • Swirl Ring P/N: 220478
