Improve quality of prints, Micromake C1
Dramatically improve X and Y and Z precision. After the modification, the Micromake C1 better printing than most 1000 dollar printer.
- The Core XZ modification eliminate the X axis wobbling (it will be a perfect circle)
- Bed linear four point underneath eliminate 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 the movement almost disappears. (reducing the amount of ghosting effect)
Due to the transformations, maximum print volumes increased:
X = 245
Y = 245
Z = 260
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

The 3mm hole i use Plastic Injection Moulding Brass Insert Round Knurled Thumb Nut
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.
