Today I have finished the front of my enclosed Ultimaker 2.
On the front I engraved a small logo just for fun 🙂
Here a few picture
The build of the Ultimaker 2 clone was great and the printer works great.
My problem is that in my workshop it’s a lot of Dust what the 3D printer don’t like.
Now I’m sketching a new frame for my printer.
Here a photo of the front from my new frame.
I also added a small sketch witch I want to carve on the front 🙂
I hade a problem with my verry verry cheap China clone Ultimaker board Ver. 2.1.4
The stepper of the Z axis and all the other axis worked but they had no torque.
After a long search I found the reason.
The current sense resistance are wrong, it should be 0.05 Ohm and mounted are 0.5 Ohm. First I thought that my mechanic was to strong so I decide to a test and connected an external stepper driver on the testpins and the mechanic is not the problem. In the video you can see my test and I added 2 pictures 1 from the wrong resistor and the other ist the schematics of the driver.
At the last few day’s I got a lot of parts.
Belts, slider, print head, extruder, stepper, z axis lead screw, .. and a few more things.
Here a few pictures:
Today my steel rod’s arrieved for the Ultimaker.
Here the order:
6 mm: 1x 300mm 2x 320mm
8 mm: 2x 337mm + 2x 348mm
12 mm: 2x439mm
Here a few picture of the rod’s
Today I milled the 4mm aluminium plate for the heated bed.
My next project begins.
Building the case of my new Ultimaker 2 + ext.
Here a picture and the production of the first parts of the frame.
