Check the correct spoiler board size for your machine here. An MDF board with 12mm thickness is suggested. Spoiler board - you will need to source this locally. We don't supply them since we ship worldwide and different countries use different plug types. Power cord - you will need to source a power cord with a plug, to connect your machine to the wall. ![]() If you acquire a MESH Workbench matching your machine size/name, the benchtop will be about 10cm wider than your machine on every direction, to allow enough clearance for an enclosure (coming soon!). You should check the critical dimensions of your desired machine size before buying (Footprint, Spoiler board size, Working Area, etc). This reduces the lever-effect of the Z axis on the X axis, allowing for even more precision and performance while cutting harder materials. Users who want to push their machine to the limit may benefit from this small upgrade that lifts the height of your spoilerboard and reduces Z travel. Tingle tension uses thrust bearings, to ensure that the tension load doesn't create friction and is not passed on to your motors. The tingle system allows you to adjust the tension your lead screw is under, to prevent lead screw whip. The KillerBee is equipped with the Tingle tensioning system on both the X and Y axis of the machine. Artifacts like this create vibrations that can be propagated to the material you're cutting, creating inconsistent cutting At these lengths, the mass of the rotating lead screw is subjected to centrifugal forces that can create lead screw whip, an artifact where the lead screw starts behaving like a jumping rope, instead of staying straight. Long machine axis are driven by long lead screws. If you take good care of your linear rails, your machine will provide consistent, high-level performance for many years to come! All you need to know about linear rail maintenance can be found here. Linear Rails should be protected from humid environments and require proper lubrication for consistent performance. The Linear Rails are one of the most expensive components on the entire machine, since they require industrial-grade manufacturing. 2 rails are used on each C-Beam with 2 MGN15C carriages per rail (for a total of 8 MGN15 rails and 16 MGN15C blocks) ![]() Rails are made of steel, providing additional structural reinforcement of the machine's frame Ball bearings are protected from dust and other contaminants by seals all around the carriage Load is carried by dozens of rigid, incompressible, low friction, stainless steel ball bearings which circulate inside an ultra compact carriage - saving a lot of space while ensuring smoothness, sturdiness and complete rigidity. Manufactured with very strict tolerances for almost zero slack The KillerBee moves away from a wheel based system in favour of a MGN15 Linear Rail system: ![]() But wheels are hard to tune right, need a lot of maintenance, and have many moving parts that wear out with time. To achieve this, slack needs to be down to an absolute minimum, and strict manufacturing tolerances are required. Smooth, precise, reliable and repeatable motion. Perfectly milled edges require perfect linear motion. The KillerBee uses 8mm thick Q235 steel plates, up to 8x stronger than the Workbee plates, so the machine won't break a sweat, whatever you choose to throw at it. A strong machine needs a strong foundation. ![]() These sturdiness improvements are the result of a few important upgrades, listed below.įorget about aluminium plates if you're serious about performance.
