What is the maximum size to which engravings or cuts may be made? The maximum work surface is 34x23cm What is the maximum height for an object? The maximum height is virtually unlimited, whereby, as a standard, materials with a height of up to 3 cm are engraved or cut. By the use of chunks, the legs (of the table) may be variably adjusted upwards or downwards, which makes it easier to also engrave higher reaching items. In addition, it is also possible to place the LightWave laser machine on top of the item to be engraved and fasten it. What is the maximum amount of mm that may be cut? The actual laser area is +/- 4mm. Attention! It is only the LightWave 5500 type of machine which can do laser cutting (and engraving). How do I position an object? By the use of a weak laser point, an object may be aligned without the object being damaged or one’s hand being injured in the process. To be precise, only bundled light is used in this mode. With the software the placement of the alignment point may be chosen freely. The laser carriage may then, by a mouse click or, more easily, mechanically by hand, be shifted and thus be placed precisely to the point. Is it also possible to laser uneven/unlevel objects? Yes. The effective laser area is +/- 4mm, i.e., if an object is lasered over a sloping edge or formed by an uneven piece of natural wood, then these would not be affected. How do I recognise the effective laser area? It is best to take a piece of black paper, for the colour black absorbs most of the light, whereby the particular point will become most visible. By the use of the software, the positioning point will be set. Then one would hold the piece of paper underneath the laser and would move it vertically up and down. One will see right away where the point is the smallest and thus most precise, and from where on it will diverge, so that the laser would hardly provide any effect or precision anymore. What does the surface of the material have to be like? The more even or smooth the surface is the more pronounced the motive will be! Is the laser also capable of engraving or cutting metal or glass? No. With regards to engraving or cutting, it suits neither metal nor glass. The capacity is not sufficient for this. Is it also possible to laser very soft materials? Yes. The laser power may be adjusted at will. It is, however, recommendable to first make a test on a testing workpiece or an offcut. How precise is the work of the laser? Resolutions of 127dpi to 508dpi may be set! 508dpi (dots per inch), in conversion, correspond to 400 laser points on 1mm². This amounts to a size of 0,0025mm² per point. As a comparison: the resolution of 4c offset/digital printing is normally 300dpi. Will my material be burnt in the process of laser engraving? Yes and no. If the material is too hard for the capacity of the laser, then it will turn black, which often is intentional. There will, however, be no flames; the material will only be engraved. If the capacity is sufficient for the material, the laser will not burn it, but will destroy certain points, yet the material will not be burnt; i.e. only an indentation with a light colour will occur. If the goal is to achieve burns, in order to obtain a contrast of a light colour material to a dark engraving, then one must either reduce the laser power or, if needed, vary the time for how long the laser should be kept on one point. What kind of underlay is required for laser cutting? In principle, a plate made of wood, cardboard or plastic a couple of mm’s thick should be sufficient. Since, starting from a certain distance, the laser beam becomes bigger and thus looses of its concentration/power, then at some point it will no longer be able to cut more deeply or burn. Therefore, only materials with a thickness of up to 4 mm may be cut. What kind of protection does the laser provide? The laser itself is unprotected! That is simply for the reason that it is so flexible that it may also treat higher reaching objects. So, by the use of chunks, the laser may be lifted or it may be placed on top of the item to be engraved. In addition, you may, however, acquire the set of "Carriage case & protection frame", which will provide safety and is suitable for mobile use. Other than in the case of fire, the laser only shoots very short light pulses onto the material, which does not provide enough time for something to be „burnt“, as it is the case with fire. Therefore, you may laser paper or cloth without hesitation, as long as the laser unit is constantly in motion. There are 2 pairs of laser safety glasses contained in the package. By using these safety glasses you may place your workpiece and also observe it during the working process. It is not recommended to look at the laser for a longer period of time! The safety glasses shall only be used for the adjustment of the workpiece and for occasional inspection. The safety glasses compensate the wavelength of the laser, whereby the blue light is filtered. However, they do NOT(!)protect from direct radiation or reflection!! Therefore, neverplace any reflective items (metal, glass...). How much noise does the laser make? The integrated ventilator runs at 40dBA. During operation the noise level is extended by the stepper motors and the laser unit to a maximum of 48dBA. That corresponds to about the level of soft radio music. May there occur also smells during the process of lasering? Yes. The smell, depending on the type of material, may be perceived comparable to something being burnt [wood|plastic|paper....]. For how many hours may I use the laser device on a continuing basis? Our tests have never exceeded 18h on a non-stop basis. The laser diode, however, is sufficiently cooled and should be able to withstand also long-term strains. How much electricity will be consumed in the process of laser engraving or laser cutting? The laser is operated by a 12V power supply (4000 mA), which, in conversion, corresponds to approximately 48 watt. When taking into account an operation time of 8 hours per day, it corresponds to a consumption of 0,384kWh per day.
