Also remember that if your material is not flat, the focal distance will not shift Of your material (we use 2" lenses in all our machines). set focal distance MANUALLY with 6" combo square (as in photos) - remember that you ideally want the 2" focal distance in the CENTER.ONLY if you have pixels to raster, (make a separate layer) and leave its line quality at 'default'. organize cut lines & reference lines by layer - change line quality (print width, by layer) to "hairline" for vector line cutting,.draw reference rectangles for 24x36 bed and material piece size/location, if different.check units, scale and orient drawing at 0,0, also check layer/object colors for consistency.TL DR? Quick reference (if new to this, please don't skip thorough instructions) It is not possible to cut materials with larger dimensions than 24x36 in. The physical dimensions of the laser bed. Drawings should be formatted to fit into a 24x36 inch bounding box that represents Begin by opening Rhino and opening a file, importing, or starting a new one- make sure your units are consistent from drawing to plotting! Must be checked in detail to ensure all settings are consistent and as expected before attempting to plot. if that isn't possible, properties of imported geometry Keep in mind that importing geometryĬan bring issues that can be avoided by starting with a new, clean file. Geometry for cutting can either be generated in Rhino or imported from other CAD softwares. Geometry can be generated and sent to the laser cutter by a number of different softwares. Provides a step by step process based on Rhino CAD software. This tutorial is meant as a reference for trained users, and There are a number of ways to send information to the laser cutter this tutorial is intentionally Reservations are not required, but will take priority (2 hrs/day maximum). Laser cutters can be reserved for up to 2 hours a day per user, on Reservations. Your top priority as a laser cutter operator will be to prevent a fire from In case of a fire, in detail, during the orientation session. MIT policies dictate that you do not attempt to put out a fire if you do not have the training or equipment necessary - we go over what to do Rules will result in loss of access to the shop, and required remedial retraining for the possibility of restoration of access. It may be added to this website in writing, when time allows.Īll users can contact shop staff for training and re-training on these and any other subjects at any time. Shop orientation includes a more detailed explanation of these safety rules. The one whose access information has been used (you will sign in to print with your MIT name/password). If the machine is operating, it must be done by Out to others, you cannot give them access to these machines - regardless of their experience. Users gain access to laser cutters as part of shop access, with a long safety orientation - thatĪccess cannot be given to anyone else. You cannot lend your access to anyone.Must make sure anything you want to put in the machine is on OUR "ok" list first. In an enviroment like this (comparable to a kitchen stove with a vent outside) - many materials burn with hideous results, as well. Users can only cut approved material - refer to our lists (link to be added - printed lists posted each machine) for what is/isn't allowed.You must be able to react to any beginning sign of a problem IMMEDIATELY, without any delay. Rule unless you are directly facing/watching with a clear view of the whole bed and the cut as it happens, until it finishes. Being near the machine does not qualify as following this Laser cutters work byĬutting/melting - every job is a fire hazard.īeing in the room is not adequate machine supervision. This means watching right at the machine,Īnd being able to immediately see any sign of a problem - without any delay. All users MUST WATCH the cut the entire time it runs.Indefinitely for willful disregard of safety rules. In return,Īll users must rise to the occasion and operate these machines, which are always fire hazards even during correct use, with an equivalentĪll users will be required sign a user agreement for laser cutter and general shop access access may be revoked Laser cutter resource to users in the school of architecture (under normal circumstances, 24/7 during any given semester). All users MUST remember and follow these at all times. Access requires a signedĪgreement which includes these 3 rules. All shop users will have taken an orientation session that goes over our laser cutter safety rules in depth.
