I have been quiet busy last week.

I performed nearly a full test assembly to check:

• what is wrong and that I need to modify: hopefully almost nothing.
• what is missing and I need to add.

As you can see, it really starts to look at a 3D Printer.

XY Gantry

The XY Gantry works correctly by hand, I do not have any binding if I turn the associated pulleys. Quiet happy with this part. I need to change a few screws that are too long, otherwise it is ok. The hotend does not seem to have any play on all the axis, I will try to measure this with a comparator.

May be I will try to find aluminum screws because M6 is very over-designed for the head and even for the remaining M5 there is no need to have a super strong assembly.

Z Axis

I had to perform some tuning for the assembly of the short version of the Z axis, and modify a bit the design. Everything is really super tight from a length point of view: I was very very lucky. It will be a good basis to implement a shorter version.

The tall one did not have any change.

I prepared a few parts for the Bed assembly, that will be covered later in another post.
