The Z homing on a BfB Rapman is insured by an inverted bolt placed at the back of the extruder.
The bolt's head is actioning the Z switch when the bed moves up.
The bed to nozzle distance can be controled by tuning the lenght of that inverted bolt.
But I think it could be made much easier...

In the last days I've been printing Hairygael's InMoov robot's left hand.
It works pretty well but I need it for a punch server robot that will have to hold a glass.
So I need the thumb to be able to close in a "C" shape with the index.

I have the opportunity to test a UP! printer from PP3DP.
In the next days/weeks I will tell you what I think about it...
But now I'd like to show you my first print with the UP!
It's a case I designed for my Raspberry Pi...

Leveling the Rapman's bed to ensure it's perfectly parallel to the XY toolhead's plane is something important.
Until now, like a lot of people I guess, I was doing it "by eye", trying to achieve a thickness of about 3 sheets of paper (hot-end/bed distance) where the 3 leveling bolts are placed (back left and right corners + middle front).
It usually is enough for classic 3D printing.
But as I allready said, for pen-plotting and especially for milling, it's important to insure that the bed is perfecly leveled. Or at least as perfect as it can be.
So we're going to need a more "scientific" way to make sure the bed is at an equal distance to the toolhead (at least at these 3 leveling points).
And I think there is an easy way...

I will need something to hold a pen in place of the original extruder if I want to use my Rapman as a pen plotter.
As usual, I'm gonna design that part in Sketchup.

When you print using the support feature with a diferent temp setting for the support, the print head will constantly go to its rest position to change its temperature.
Doing so, it will deposit some stringing on the printed object.
Let's see if we can manage to find a solution for that...

Unless you mounted the PCB fan on its wrong side (which you should better check twice - 99% of the Rapman I've seen have been built with both fans upside-down !), you are probably pissed off having it sucking the dust from your desk !
And I don't even speak about the generated noise.
Let's try to find a solution for that...

The plastic conduits are just laying on my desk if I do nothing.
It's not a big deal but it could be better...

In my previous post I've been printing Bogdan's right Y belt holders.
But I didn't find any allready done spare parts to replace the left Y belt holders.
So I decided to design them...

Among the spare parts designed by Bogdan I decide to print the Y belt holder...

The way the bearing blocks are held on the original kit design is not ideal.
Bogdan has designed a set of spare parts to replace the bearing blocks.
So I'm gonna print and use them...

Not only the extruder connector is unprotected.
The PCB itself has all the electronics visible...

Let's have my Rapman print parts for itself !
