Regretfully Just Add Sharks Ltd has closed at the end of September 2017. Over the last year Just Add Sharks Ltd has faced challenges with the vanillabox crowdfunded Open Source laser cutter project and with leads times from their suppliers. Demand for low cost laser cutters has outstriped the supply. Lack of timely supply causes delays and disappointments to customers. This is further exasperated by the drop and fluctuating value of pounds sterling. Just Add Sharks Ltd will honour all customers manufacturers warranties.

Customers should continue to email their requests for technical support, software support, spare parts and warranty enquiries to or using the contact form below.

Key Features

300mm x 400mm cutting area
The cutting area holds a sheet of A3 card, but there is an additional 100mm on each side of the Laser cutting area for oversized objects
1,100mm x 660mm x 450mm machine size
The laser cutter has a compact size that would easily fit on a bench in a shed or garage, all of the external connections are on the sides of the machine so it can be pushed against a wall.
40w laser tube
The 1000mm long laser tube produces a peak output of 60W and 40W of continuous cutting. It will typically cut through 3mm birch laser ply at 15mm/s. The 40W tube extends out the side of the case by 35cm in an protective enclosure. The tube should last for around 1200 hours and comes with a 3 month warranty.
Lasercut 5.3 Controller
The laser uses the Lasercut software package from Leetro automation. It is capable of importing dxf files such as those created by 2D design and Adobe Illustrator.
100mW Red dot alignment
The laser aiming dot is particularly helpful to optimise your material usages and for realign work after removing it from the laser cutter.
Work Stand
A free standing frame with lockable wheels lifts the laser cutter to a sensible working height and allows easy access behind the cutter for maintenance. If removed from the stand for mounting on a workbench, the Blacknose A3 laser cutter is 45cm in height.
CW3000 Chiller
The chiller is a passive air cooled radiator chiller, Size (L x W x H) 49 X 27 X 38 cm
Powerful extraction
Vaporised material can leave significant staining on the work piece, the extractor fan draws the smoke out of the machine and away from the work in progress.
Air assisted cutting
A 120 L/Min compressor pumps air through a pipe right up to the cutting head. Air assist improves the cutting effectiveness and protects the optics from smoke damage.
Honeycomb bed
A closely packed framework of end on metal sheets. The dense arrangements supports all the work while cutting small items, the end on style reduces the number of laser reflections that burn the underside of the work.
Knife bed
A dozen vertical slats support large pieces of work during cutting, the vertical arrangement limits the number of laser reflections that burn the underside of the work.
LED illumination
A row of LED lights under the X-axis provides even illumination of the work piece during cutting.
