How is the heated bed attached to the linear guide assembly ? |
| picclock:
Hi nmrl The heated bed is attached to the glass with clips as per normal, as shown in the picture. Best Regards picclock |

Hi picclock, The bits are coming together nicely! Following with great interest! /Peter |

Sorry I meant to ask how it was attached to the bearing linear rod assembly. Is it glued on to the little fibreglass boards or just clipped on? I can't quite figure it out from the picture. |

Hi nmrl The twin bearings are epoxied to a fibreglass carrier, and the glass is clipped to that. The single bearing is located in an open top 'box' which constrains axial movement but allows radial movement. Its only function is to maintain an accurate distance above the smooth rod. Gravity and the glass weight should keep it in place but for convenience I will fashion a clip, probably out of piano wire. So the twin bearing smooth rod will control x,y,and z about the axis, And the single bearing is just responsible for the z component. This leaves the glass easily swappable, with the only snag being the possible collision of head and belt clamp if not set up correctly. The distance between the smooth rod centres was changed to 230mm to facilitate this, also giving greater lateral stability. Best Regards picclock |
