Micromake C1-M (Modified C1)

thingiverse

Improve quality of prints, Micromake C1. Dramatically improve X and Y and Z precision. After the modification, the Micromake C1 prints better than most $1000 printer. The Core XZ modification eliminates the X axis wobbling (it will be a perfect circle). Bed linear four point underneath eliminates bed vibration and bending. The previous two result in very uniform Z layers at one time (and easy bed leveling). Due to the double fixation, the twisting between the Y and Z frames movement almost disappears. (reducing the amount of ghosting effect) Due to the transformations, maximum print volumes increase: Original X = 245 Y = 245 Z = 260 New X = 280 (Compact Z carrier) Y = 280 (longer Y axis) Z = 270 (lower bed) I use 300x300 glass on bed. (these new dimensions must be overwritten in the firmware, see the picture above) I set all printable parts to the correct print position Part needed: frame: 2x460mm 2040 alu profile https://www.aliexpress.com/item/HOT-Sale-CNC-3D-Printer-Parts-European-Standard-Anodized-V-Slot-Linear-Rail-Aluminum-Profile-Extrusion/32813630598.html?spm=a2g0s.9042311.0.0.781iM0 1x360mm 2040 alu profile + (use the remain Y axis 2040 profile, cut 360mm) https://www.aliexpress.com/item/HOT-Sale-CNC-3D-Printer-Parts-European-Standard-Anodized-V-Slot-Linear-Rail-Aluminum-Profile-Extrusion/32813630598.html?spm=a2g0s.9042311.0.0.781iM0 Y axis: 2x 500mm 8mm dia steel rod https://www.aliexpress.com/item/2pcs-NEW-8-500mm-Long-steel-shaft-metal-rods-diameter-8mm-DIY-axle-for-building-model/32727032946.html?spm=a2g0s.9042311.0.0.Nxyy1b 4x LMUU8 equivalent bearing (igus drylin 8mm nylon bearing) https://www.aliexpress.com/item/2pcs-lot-3D-Printer-Solid-Polymer-LM8UU-Linear-Roller-Bearing-Rod-with-Housing-For-CNC-Machine/32842140058.html?spm=a2g0s.9042311.0.0.L5psiW The 3mm hole I use Plastic Injection Moulding Brass Insert Round Knurled Thumb Nut https://www.aliexpress.com/item/100pcs-M3-M3-4-3-ID-OD-L-Copper-Injection-Moulding-Brass-Insert-Round-Knurled-Thumb-Nut/32705709306.html?spm=a2g0s.9042311.0.0.L5psiW The original bed should be drilled and cut out as shown in the picture above! Important! : before the use printer after core XZ modification, in the firmware change XY stepper motor rotate direction! See the picture. Update 2018.04.13. Added some picture and Z carriage set (L and R) this part needed support (a little)! Update 2018.04.17. Remove old upper idler and added my own design better upper idler. two version, two design. Common features - Anti twist design (it does not loosen, himself) - Swing horizontally to stretch and loosen the belt if necessary - Built in spacer (Only one washer needed, between the gears) - Open design (visible the gears) Update 2018.05.16. Added New LCD Frame, holders, and Motherboard holders (Removing the outer box, the control card is placed inside the frame and the LCD is on the front of the frame.) - LCD frame front with percent scale signs. - Experimental suggestion: 100% infill recommended for exposed to load element ! Update 2018.09.15. Added my own design Igus RJMP-01-08 equivalent printable bearing. (This bearing 100% fit my own design holder.)
