Some more parts and Frame Part 1

The mounts for the steel rods of the y-carriage arrived today. They are made of aluminium and black anodized. The steel rods are heat in place by some set screw instead of zip ties. If this is better? Well, time will tell.
To mount them you need M3x10 screws. Only problem I found is that the holes for the screws are either not tapped properly or during the anodizing process they messed it up.


And as I have most of the parts now, I decided to mount the frame today. So what you need is the frame parts and 32 M5x16mm screws.



And do not forget the T-nuts for the power supply and the rubber feet, before you attach the front and rear plates.


The most important thing about the frame is to get it square. I strongly recommend to follow the instructions from Prusa. They are very detailed and very good.
Prusa MK3 assembly instructions

And this is the result, my cloned Prusa MK3 frame.



As you can see the frame is not really black. The frame parts seem to be powder coated, not anodized like the extrusion parts. This coating is thick and has some metallic effect.
But the holes did fit, some where a little tight because of the coating.

A new project "automatic cat litter box"

 I did not post any updates for a long time. I spent some time making some money with 3D printing to recover some of the costs from this hob...
