The movement of the part along these rails is done by attahing a GT2 belt to the part and pulling it in either direction with a basic NEMA stepper motor. Both roller ball and polymer bushings perform well, however solid polymer bushings will last far longer and are nearly silent in comparison. Parts are mounted to linear rods by tightening them down around either roller ball or solid polymer bushings. Linear rods are the personal favourite of Dero.Solutions. Fully understanding how each of these work will allow for a good balance of the group, resulting in an affordable, effective machine. Linear rails and rods are accurate, but more expensive with rails being noisier and rods being more difficult to design for. Grooves and v-Slots are the least expensive option, but are the least accurate and wear fastest. There are 3 primary means of motion along any given axis: sliding over linear rods, sliding attached to a linear rail, and rolling along grooves in aluminum extrusions. Motion - Linear Rods, Linear Rail, & V-Slot Wheels To truly get the most out of the product, you must understand how each part of the machiners affects the results. Cartesian printers have their natural instability and CoreXY have their complexity and inconsistency between manufacturers.

If they are installed correctly, they will not make contact with the v-rollers or the LED's.With the purchase or build of every printer comes the ups and downs of its design. Rotate them slightly with tweezers, then pull them out. You will need to place them in at an angle and then flatten them once they are beneath the main slot down into the v-portion of the extrusion bar. Start with the 200mm, and scale only the length dimension (leaving width and height at 100%) to whatever dimension is desired. The easiest way to accomplish this is in your slicer. However, you will need to create the sizes you need for those. You may also install these on any v-slot that has rollers. How you install your LEDs will determine which sizes you need. Realistically, the height on the inner slot is ~400mm, but on the side where the wires run out, you may not be able to fit 2x200mm covers which is why the other sizes are provided.

24V 2835's are extremely bright and definitely look much better with diffusers in front of them and can also benefit from a dimming circuit (another design I've made). This is a v-slot cover intended to be installed beneath roller wheels and used as a LED light diffuser for SMD 2835 (and similarly sized) LED strips installed into the 2040 extrusions on the z-axis.
