Progetto cnc asse x z

thingiverse

Here is the rewritten text: Project of a CNC machine made with the idea of spending as little as possible, therefore using recovered material from printers such as the NEMA 17 motor and related gear (2-to-1 coupling) for the Z-axis taken from an Epson printer, as well as the 8mm bars of the Z-axis. The X-axis bars of 12.5mm come from HP printers. The lathe I used is a cost-effective version of Dremel and the mounting bracket is custom-made; it may be necessary to modify it to fit your lathe. Two x-direction bearings (dx and sx) and two support bar bearings must be printed. As printing settings, I used PLA with 30% infill and only Brim for large parts, supported on the plane only for Support Bar Bearings. Additional materials: -Bar M6 and more than one bolt with a counterbore, filet M6 internal and 10mm external (found easily in hardware stores for furniture) -4 Axial bearings (https://it.aliexpress.com/item/32908983254.html?spm=a2g0s.9042311.0.0.261d4c4dvTELwF) to fix the M6 bar to the Z-axis frame -4 SCS8UU bearings (https://banggood.app.link/vk2tRAvGQ7) for the Y-axis -One T8 bar and related bushing for X and Y axes (https://banggood.app.link/foUz8ohEQ7) -One 80x75mm wooden plate, 15mm thick, to which the SCS8UU bearings are fixed on the back with a central Z-axis attachment, and in front of the lathe supports -One 94x175mm wooden plate, 15mm thick, is fixed between the Z-axis frame and the X-axis bearings, with a central X-axis attachment -NEMA 17 motors for X and Y axes -Kit of electronic control (https://banggood.app.link/yPBCJ9NLQ7) -M4x45 screws with flat head and bolts -M4x30 screws with flat head -M4x25 screws with flat head -Wooden screws of various sizes -Microswitches for fine adjustment (https://banggood.app.link/VdxgVN0GQ7) To have the correct distances of fixation and linearity, screw the SCS8UU bearings to the small wooden plate only after mounting the bars in the Z-axis frame (the two internal lateral screws also hold the lathe supports), same thing for the X-axis bearings, which must be fixed on the large plate only after inserting the X-supports. The screws in the four external corners are inserted into the Z-axis frame and screwed into the bolts inserted in the corresponding hole on the X-axis bearings. Note: I re-made the X-axis bearings several times to find the right sliding on the bars without play, it may be necessary to make a small adjustment to the size of the sliding hole, if necessary contact me and I'll answer as soon as possible.
