'''<div style="font-weight: bold; font-size: 110%">NOTE: This is our old laser cutter which has now been replaced with the [[Silvertail A0 Laser Cutter]]. This page is left here for reference.</div>'''
 
We have a HPC LS3060 laser engraver and cutter, with a cutting area of 300mm x 560mm. Trained [[Membership | members]] can use it for the very reasonable rate of £5 per hour.
 
This cutter was sold.

==Status==
The cutter is currently operational - check the [[Equipment/LaserCutter/LogBook|logbook]] for more information.


==Model==
==Training==
* [http://hpclaser.co.uk/ HPC] LS3060 "plus" laser engraver and cutter.
 
====Specification====
You must not use the laser cutter without being trained. The laser cutter is unlikely to hurt you, but you can easily hurt '''it''' without training.
{| class="topalign"
 
| '''Laser:'''
Training is given most Wednesdays or Thursdays at around 8pm, is free to attend and available to all members but your place needs to be pre-booked. Space is strictly limited per session so you need to reserve a spot on the [[Lasercutter_Training|Training Roster]] when a session is available - watch the [[Mailing List]] for announcements. Reserving a spot is on a first come first serve so you'll need to be quick. If you can't attend your training session please remove your name from the roster and inform the Mailing List, this will save wasting people's time and can allow a last minute replacement to take your slot.
|| 40W - water cooled CO<sub>2</sub> laser.
 
|-
Training is currently limited to members only but this may change in the future.
| '''Working area:'''
 
||320 x 600mm honeycomb bed (cutting area possibly about 300 x 550mm)
A good way to get notified of new training sessions is to go to the roster page, add it to your wiki page Watch list, and modify your wiki account preferences so that you receive emails when pages you Watch get modified.
|-
 
| '''Features:'''
Feel free to ask for help on the [[Mailing List]], but please read the [[Mailing_list_FAQ|FAQ]] first
|| Air-assist (removes debris from cutting region),
 
red-dot pointer (to show beam location)
==Costs==
|-
 
| '''Water cooling:'''
* Training - Free
|| Simple tube cooling circuit connected with (9mm OD, 6mm ID) latex tube.
* Usage - £5/hour
Uses supplied submersible pond pump (2.8m head, 2800L/H flow).
* Consumables - Bring your own and/or use what is in the off cuts bin, but always ensure (rather than assume) it's [[Laser_Cutter/Instructions#Chlorine_Testing_and_Material_Safety|laser safe]].

==Safety information==
==Safety information==
'''<div style="color:red">Please don't touch or fiddle with the laser cutter unless you've have been trained.</div>'''
* '''Don't touch the cooling system without asking first''': overheating or rapid cooling can damage the laser.
* '''Never leave the laser cutter unattended while cutting''': your material may ignite, and an unchecked fire in the laser cutter could be both dangerous and costly. We've also seen mirrors go out of alignment and cut into the cables, This is what a laser cutter fire does to a laser cutter:


* '''Please don't affect the cooling system without consultation''' - overheating or rapid cooling can damage the laser.
[[File:lcfire.jpg]]
* '''Never leave the laser cutter unattended''' - Your material may ignite, and an unchecked fire in the laser cutter could be both dangerous and costly.
[[File:lcfire2.jpg]]
* '''In case of fire''' - Use the CO<sub>2</sub> extinguisher by the laser cutter first. Do not use the powder extinguisher unless you feel that you can't control the fire.
* '''Never cut PVC or chlorinated plastic''' - You should always know what material you are cutting, and chlorinated plastics should be avoided because they release chlorine gas when cut.
* '''Do not try to cut metal in the laser cutter''' - If you wish to mark the metal, please use [http://hpclaser.co.uk/index.php?main_page=product_info&cPath=2&products_id=17 "Thermark Laser Engraving Spray / Paste"], or use anodised aluminium.


==Instructions==
* '''In case of fire''': use the CO<sub>2</sub> extinguisher by the laser cutter first. Do not use the powder extinguisher unless you feel that you can't control the fire. '''[http://bit.ly/LaserLogbookForm Put it in the logbook] and tell the [[Mailing List]]''': tiny flames while cutting are normal; anything more must be reported.
These instructions are intended as a companion to [[Workshops#Regular_Hackspace_workshops|laser cutter safety training]] - not a replacement.
* '''Never cut PVC or chlorinated plastic''': you should always know what material you are cutting, and chlorinated plastics should be avoided because they release chlorine gas when cut. [[Laser_Cutter/Instructions#Chlorine_Testing_and_Material_Safety|Guidelines for how to test materials.]]
====Powering on====
* '''You can't cut metal in the laser cutter''': if you wish to [[Laser_Cutter/Metal|mark the metal]], please use [http://hpclaser.co.uk/index.php?main_page=product_info&cPath=2&products_id=17 Thermark / Cermark], or use anodised aluminium.
# Insert key and turn
 
# '''Always''' perform the following pre-checks:
==Using the laser cutter==
## Check that there is a '''CO<sub>2</sub>''' fire extinguisher '''immediately to hand'''.
 
## Check that the water pump is running
# Make sure you're familiar with the [[Laser_Cutter/Instructions|operating instructions]].
## Check that the extractor fan is on
# Look up the laser cutter parameters for the material you're using (see bottom of this page).
# '''Caution:''' Be certain that the water coolant is at a suitable temperature.
# Use the [[Media:LHS-Laser-Cutter-Checklist.pdf|LHS Laser Cutter Checklist]] to ensure that you don't forget anything important as you cut.
#* If you are unsure if the cutter has been '''used recently''', or you have been using the cutter for an '''extended period of time''' (an hour or so) check the temperature of the water using the infra-red thermometer.
# [http://bit.ly/LaserLogbookForm Log your use] to help with the upkeep of the lasercutter. (Records can be viewed [http://bit.ly/LaserLogbook here].)
#* If the water temperature is outside the acceptable operating range (22 &plusmn; 3 &deg;C) then wait for the water to cool before using the cutter.
# Pay for your usage - the cost is £5 per hour, which is just enough to cover our [[Laser Cutter/Maintenance|maintenance costs]].

* [http://www.blueprintmodel.co.uk/ Blueprint Modelshop] There's a commercial laser cutter service 10 mins from the space, DIY service is £30/h (as of 2013). You can buy acrylic there, but it's coated with horrible sticky paper rather than easy-to-peal plastic.  Beware.


====Uploading your data file====
==Manuals==
* '''TODO''' Different file types pros/cons
* [https://www.bosslaser.com/images/pdf/User%20ManualDSP5.3LaserCut53.pdf LaserCut software manual]
* Sometimes it's useful scale your design. The Laser cutter application allows for this but it's rather quirky:
* [[:File:JSM3040N&3060N Manual.pdf | HPC LS3060 hardware manual]]
** From the Laser software menu select 'Tools/Size'
* [http://www.leetro.com/english/down/MPC6515%20%20Manual.pdf Controller manual]
** Calculate and enter your new widths/heights in Google/calc etc.
* [[Equipment/LaserCutter/LogBook|Maintainers Logbook]]
* '''TODO''' Setting the origin - what to watch out for
* '''TODO''' Layers - how are they used
** Power settings, speed.
* '''TODO''' How do you know when the file is sent successfully


====Positioning your material====
==More information==
* '''Caution:''' Know your material - be absolutely certain that your material is safe to use in the laser cutter. If in doubt - ask. For unidentified plastics try [http://www.nycresistor.com/2008/08/28/how-to-identify-polymers-with-burnination/ this test method].
* How the [[Equipment/LaserCutter/CoolBot|cooling system]] works
* '''Caution:''' There are a number of electrically live areas inside the cabinet towards the back. Be very careful when reaching around at the back as you may get a shock.
* Some useful [http://www.ladyada.net/library/laser/index.html laser info from Adafruit] - the settings section in particular gave a good idea of what we can expect.
* Place the material on the cutter bed.
* More information about the controller card used by the cutter  
* The bed height must be adjusted to the thickness of your material. This can be done as follows:
** http://www.leetro.com/english/sale/20.html
** Press the 'Z' button on the [[:File:Laser-Cutter-Screen-Z-Axis.jpg|control panel]] with your material on the bed.
** http://www.leetro.com/english/sale/23.html
** The display will show 'Z-Axis operate'
** [http://www.jqlaser.com/service/service.html Latest version of the software]
** Then press the 'Datum' button
** [http://www.leetro.com/english/down/59.html Firmware for MPC6515 controller and software] (hit the download page for latest version)
** The display should now show 'Z-Axis datum' and the bed should move to the correct height for your material.
* For making boxes you can use:
* To make sure that your design will be cut within the boundary of your material you can have the cutter mark out the bounding box with the red-dot pointer. Note that you must upload your design to the cutter before doing this.
** [http://www.thingiverse.com/thing:404 this script] - recommended settings of "--bolt_length 13 --nut_multiplier 1.8" YMMV
** Click the [[:File:Laser-Cutter-Screen-Run-box.png|'Run box' button ]] in the laser cutter application
** [http://rahulbotics.com/personal-projects/boxmaker/?boxmaker/ BoxMaker] is also _very_ good for making boxes.

====Cutting====
==Laser Cutter Parameters - Background==
* '''Caution:''' Never leave the machine unattended. The laser cuts and engraves by burning the material so '''you must be present''' to deal with any fires should this process undesirably escalate.
===Thick Material===
* Turn on the air pump on the [[:File:Laser-Cutter-Screen-Control-panel.jpg|main control panel]]
Do not try to cut anything thicker than the thickest width listed for that material on this page.
* To begin cutting press the [[:File:Laser-Cutter-Screen-Start.png|'Start' button]] in the laser cutter application.
===Corner Power===
* Monitoring progress
When the path goes round curves, or a straight line passes close to previous line (TBC), the laser will slow down. As a consequence, the Corner Power needs to be lower to compensate. Typically about 80% of the Power setting.
** '''TODO''' What to watch out for
===Lowest power===
** '''TODO''' What to do in case of problems
Setting the power below 10 or 11 means that the laser will not activate.
* '''TODO''' What to try if the result is not what you expect
===Tried but DIY parameters===
* Log your Laser Cutter use in the [[Equipment/LaserCutter/LogBook|logbook]]
Laser rubber has been used (mainly for stamps) it works well but you'll need to experiment for engraving/cutting.  Check out [[Laser_Cutter/Parameters#GradeEngrave]], which is useful for rubber stamps.

NOTE: This is our old laser cutter which has now been replaced with the Silvertail A0 Laser Cutter. This page is left here for reference.

We have a HPC LS3060 laser engraver and cutter, with a cutting area of 300mm x 560mm. Trained members can use it for the very reasonable rate of £5 per hour.

This cutter was sold.

Training

You must not use the laser cutter without being trained. The laser cutter is unlikely to hurt you, but you can easily hurt it without training.

Training is given most Wednesdays or Thursdays at around 8pm, is free to attend and available to all members but your place needs to be pre-booked. Space is strictly limited per session so you need to reserve a spot on the Training Roster when a session is available - watch the Mailing List for announcements. Reserving a spot is on a first come first serve so you'll need to be quick. If you can't attend your training session please remove your name from the roster and inform the Mailing List, this will save wasting people's time and can allow a last minute replacement to take your slot.

Training is currently limited to members only but this may change in the future.

A good way to get notified of new training sessions is to go to the roster page, add it to your wiki page Watch list, and modify your wiki account preferences so that you receive emails when pages you Watch get modified.

Feel free to ask for help on the Mailing List, but please read the FAQ first

Costs

  • Training - Free
  • Usage - £5/hour
  • Consumables - Bring your own and/or use what is in the off cuts bin, but always ensure (rather than assume) it's laser safe.

Safety information

  • Don't touch the cooling system without asking first: overheating or rapid cooling can damage the laser.
  • Never leave the laser cutter unattended while cutting: your material may ignite, and an unchecked fire in the laser cutter could be both dangerous and costly. We've also seen mirrors go out of alignment and cut into the cables, This is what a laser cutter fire does to a laser cutter:

  • In case of fire: use the CO2 extinguisher by the laser cutter first. Do not use the powder extinguisher unless you feel that you can't control the fire. Put it in the logbook and tell the Mailing List: tiny flames while cutting are normal; anything more must be reported.
  • Never cut PVC or chlorinated plastic: you should always know what material you are cutting, and chlorinated plastics should be avoided because they release chlorine gas when cut. Guidelines for how to test materials.
  • You can't cut metal in the laser cutter: if you wish to mark the metal, please use Thermark / Cermark, or use anodised aluminium.

Using the laser cutter

  1. Make sure you're familiar with the operating instructions.
  2. Look up the laser cutter parameters for the material you're using (see bottom of this page).
  3. Use the LHS Laser Cutter Checklist to ensure that you don't forget anything important as you cut.
  4. Log your use to help with the upkeep of the lasercutter. (Records can be viewed here.)
  5. Pay for your usage - the cost is £5 per hour, which is just enough to cover our maintenance costs.

List of allowed and banned materials

Allowed

  • MDF (up to 4mm)
  • Plywood (Up to 6mm) Note: Denser/poor quality ply will have trouble cutting deeper than 4mm, use poplar or another less dense ply for 6mm
  • Balsa wood
  • Non-resinous wood IE hardwood (Engraving only)
  • Paper (Cut only, don't engrave)
  • Card/Cardboard
  • Acrylic (up to 10mm)

Banned

  • Food
  • Body parts
  • Plastics containing PVC
  • Plastics containing ABS
  • Fibreglass
  • Glass
  • Circuit boards
  • Polycarbonate
  • All metal (except anodized aluminium)

You should only be cutting materials on the Allowed list, if you want to cut a material which is not on this list, contact one of the trainers and get them to OK it first.

    • Price guide 320x600x4mm (laser bed size) clear acrylic = £8 + VAT (=£9.60).
  • Acrylic-Online - Elliot has bought some Palglas from here. They cut to size - delivery £8.00. Price guide (incl. VAT):
    • 320x600x4mm (laser bed size) clear acrylic (Palglas) = £5.12
  • Hobart Laserables - wide range of materials: MDF, Birch, Acrylic (clear and coloured), Rubber, Laminates, Anodised metal. Prices seem competitive. Nigle has ordered from here. Shipping is £12.
  • Fred Aldous – online craft supplies, free delivery on orders > £30. Polypropylene sheets amongst other things. Alex P has ordered from here.
  • 4D ModelShop is not too far from the space, and is open Saturdays. They offer laser cutting too, and hence seem to have a lot of suitable materials. Helpful staff and a good selection.
  • Blueprint Modelshop There's a commercial laser cutter service 10 mins from the space, DIY service is £30/h (as of 2013). You can buy acrylic there, but it's coated with horrible sticky paper rather than easy-to-peal plastic. Beware.

Laser Cutter Parameters - Background

Thick Material

Do not try to cut anything thicker than the thickest width listed for that material on this page.

Corner Power

When the path goes round curves, or a straight line passes close to previous line (TBC), the laser will slow down. As a consequence, the Corner Power needs to be lower to compensate. Typically about 80% of the Power setting.

Lowest power

Setting the power below 10 or 11 means that the laser will not activate.

Tried but DIY parameters

Laser rubber has been used (mainly for stamps) it works well but you'll need to experiment for engraving/cutting. Check out Laser_Cutter/Parameters#GradeEngrave, which is useful for rubber stamps.

GradeEngrave

What happens when you use GradeEngrave

Grade Engrave will cause an area inside a engraved area to have raised edges. It is intended for easier rubber stamp making but can be applied to any real use. See the Nottinghack wiki for more details.
