Geeetech A30 Y MGN12H Linear rail mod
Description
The steps are as follows: - print 2 guides and the other pieces you need - remove the heated bed - remove the belts - remove the bed - apply the 2 guides - loosen the screws that secure the 2 long Y 2020 bars - place the bed with the printed guides - slide the bed to perfectly align the 2 long Y 2020 bars - tighten the screws of the 2 long bars Y 2020 - drill with a tip 3.5 - remove the 2 printed guides (You can trash them, they are not more required) - apply the 2 rails MGN12 but do not tighten them - fix the bed to the guides MGN12H - slide the bed and tighten gradually: in this way the 2 rails align In my printer I had to make the rails protrude from the front, because I had designed the holes of the MGN12 guides too far apart. The design I uploaded has been fixed You need - 2x 500mm MGN12H rail http://s.click.aliexpress.com/e/FRtpNpfK - 4x MGN12H blocks http://s.click.aliexpress.com/e/tPaqOmqk - 10/12 M3 t-nuts http://s.click.aliexpress.com/e/qsa9Hg2c - 10/12 M3x8 screws for the tracks and 16 M3x8 for the guides http://s.click.aliexpress.com/e/2B6eKbYy You will need the new endstop support that you find in my files. For those who, like me, use the sensorless home, find the relative holder in my files. If you want to offer me a coffee for the time wasted in planning and testing, it will be appreciated Here a demo video: https://youtu.be/hJnAHdRcaTY
