Boxford Laser Cutter 2023 Pledge Drive

This is a pledge drive to purchase a second hand Boxford BGL1390 laser cutter from a local person who has offered it at a good price and has kept it in good condition, with light usage. If purchased it'd replace the current 9 year old laser (which would likely be sold).

• Misc Spare materials (will be used for workshops)

If we reach £3600 and go over money will go towards the below items:

• Spare mirrors and lenses
• Improvements to the laser area
• Running the Hackspace

Pledge Money for Laser Time and Inductions Information

Like the first laser cutter pledge we will be allowing the pledge money to be also used against the cost of using the laser in the future.

It has been decided by the Trustees the cost will not be increasing from £3 per hour which is judged to keep it at a good, affordable level and cover usage, parts and repairs.

To use the new laser cutter you will need a safety and Lightburn software induction. If you have already had an induction on the current laser this will be free and these will be done in groups. The laser team is prepared to commit the time to do this.

Inductions for members not already inducted on the current laser will continue to be paid one to one sessions bookable on HMS (cost £20).

Information and Background on the Boxford Laser Pledge

Boxford Laser

We were recently offered the opportunity to purchase a laser cutter that is surplus to the requirements of the owner. The machine in question is a Boxford 100W with A0 (1300mm x 900mm) bed.

It was purchased in 2021 and has had relatively little use, mostly during Covid when their primary business was on hold.

The machine has a built in chiller, air assist compressor and advanced control panel with screen. It also has front and back pass-through panels that are easily opened and closed, allowing sheet materials larger than the bed to be processed. To assist in maintenance all parts of the system are accessible by removable panels.

Also included is a rotary attachment which has not yet been used. There is also a camera to assist in positioning work on the bed accurately.

The laser has been well looked after with the honeycomb bed in excellent condition with only a little residue. It has been tested by the laser team doing cuts and engraves.

The user had a small fire in the machine that led to one of the clear lid panels being damaged. This has now been made good but unfortunately it also affected the auto focus system which is currently not working and we will be seeking to fixing this as part of the pledge. Other than this, the machine is in good condition and is recommended to us by Dominic and is recommended by the Laser Team for purchase.

Software is Lightburn which is one of the best laser control programs currently, allowing use of many different file formats including both raster and vector files.

When new this machine cost £8932, but the owner is looking for £3500 for a quick sale and we want to fix the autofocus for an additional £100 for £3600 total.

Our Current Laser

The current laser cutter was discussed in the last Members Meeting, and rightly the question was raised about fixing or improving the current laser cutter.

Our current laser cutter is currently over 9 years old and in recent times (3-4 years) we have seen multiple problems develop which despite servicing by a professional engineer continue to plague us.

Lasercut software on the PC has always been unreliable, sometimes failing to load files, even the regularly used induction files from both hard drive and removable media and failure to download files to the laser for cutting. Multiple attempts usually result in success but there is no pattern to the problem.

Intermittently the laser head will jog around 10mm to either left or right while cutting and continue while maintaining the offset.

While the base bed on the laser is level, both knife and honeycomb beds have problems with the honeycomb bed having a significant dip in the middle, this may be contributing to uneven cutting with parts of projects not cutting through completely.

We have also had instances of the cut becoming random during a session, which can result in a waste of materials.

While some of these issues could be resolved by modifying the laser, we are faced with it being taken offline for indeterminate periods while work is done and tested. This could cause upset amongst users of arguably the most popular tool in the Hackspace, especially as there is no guarantee of the machine being fixed by this work.

The Laser Team recommends this Pledge Drive to raise the funds required to purchase the Boxford as it will quickly solve the current issues, while giving a significant upgrade in laser performance (25% power increase and much wider capabilities with Lightburn).

FAQ

How/when will the new laser be installed?

The seller wants it gone ASAP so it could arrive quickly. If we can arrange installation at the same time this will be announced to all members. The lift is currently out of order so will depend on that being fixed.

The new laser will require a short reinduction as noted before, but these can't occur until the new laser is installed.

What is happening to the old laser?

It will hopefully find a buyer since it is in working order. If you are interested, contact the Trustees!

Pledge List

Add your pledge to the bottom of the page if you have a wiki account (the password is the same as your HMS account) but if you can't access let the trustees know. Your pledge money will be requested once the pledge is fulfilled and once we have the money the laser will be purchased.

We are reviewing the pledge list on Saturday 5th of August.

When paying the code will be LASER2023-XX where XX is your initials. Do Not send money until we call in the pledges
