Thanks!
I'm not going to supply a BOM of the build.
You have to figure out for yourself what's needed ;-)
The many pictures and sketchup file must be enough to get you going.

 

Which parts do you mean?, i can help you out with that though

 

Those are "hand made" plates from a sheet of aluminium (3mm thick), cut on a table saw

 

Quick post of my first prints... ever
A little cube of 1 x 1 x 1 cm
Layers are very consistent, definitely need some extensive tweaking (temperature in the first place i guess) but i'm very happy with these 3 first prints. no problem with sticking to the build plate whatsoever (use glue stick on glass)
PLA, Heated bed 70C, Nozzle 190C, layer height 0,2mm, fan from 3rd layer onwards.
width/depth varies a bit from 9.99 to 10.03 mm
height approx 8.80 mm (first layers little too hot / sagged / sqeezed to bed?)



first 2 prints (background) only got halfway, due to overheating problems i think. (need to look into it)
Third print was printed with a big fan blowing on to the ramps board.
I'm have to rethink the cooling part i guess
Next week i'm snowboarding in the alps, after that, i'll be tinkering again..

 

Quick update;
After a number of cubes, i printed my first (useless )"figure".
Printed in PLA with 0,2mm layer height, shell thickness 0,8mm, speed 50mm/s, bed 70C, nozzle 190C
Print cooled only from one side (the right), so left side is not as tidy.
No additional tweaking done yet.
The print looks pretty decent, alltough a good photograph reveals lot of imperfections to attent to :

 

When printing, i noticed a 'weavy' pattern in straight walls.
This was due to the extruder motor not turning smoothly, but with little 'ticks'.
This issue was solved completle when changing the motor driver from an DRV8825 (1/32 microstepping) to an A4899 driver (16th stepping)
Now some other minor issues are getting my attention. I also found out that ui prefer printing in ABS than PLA.

I noticed some erratic movement of the Z-probe servo.
I've put a resistor of 220 ohm between signal and ground which seems to eliminate that issue completely.


I've printed a fan duct in ABS for cooling the print when doing PLA.
It is based on number 491316 found on thingiverse, but altered it to my needs. The fan can be taken of easily by unscrewing
one M5 bolt from the back
I had hooked the fan up to output D9 on the ramps board so the fan would automatically turn on at a given print height.
This was troublesome; Even when the fan was not turned on, the nozzle temperature (often) went nuts and kept on rizing..
The temp measurements of the nozzle were still ok, but the temp kept on rizing beyond the set temperature.. weird?
Now i'm not using D9, but added a manual switch which i active when the first layer is printed. Works fine.



Maybe i should experiment with sticking ferrite clips onm some wires or twist some wires.

 

After switching to the A4899 driver for the extruder, and lowering the nozzle temp down to 185 C (was using 190 C upto now), my PLA prints start to look pretty OK.
Picture taken from prints without any touching up:

I'm using dutch made PLA and ABS, so no chinese stuff for me ;-)

 

Okay, that's nice to know, i haven't read that anywhere? (any informative links?)
The silence was the main reason to go for 1/32 stepping.
Future thoughts; Maybe an upgrade to an Arduino Due and a RAMPS-FD board?

 

Alright, thanks!
When googling, i found some info about the Arduino not been able to cope with 1/32 microstepping on 0.9 degree stepper motors, but on 1.9 degree motors should not be a problem.
Still, you've got me thinking; Occasionally i have a small X-axis shift in bigger prints.
The construction of my printer is as rigid as can be so i was thinking about magnetic interference between signals.
Missing steps due to 1/32 stepping like you say could also be a reason. Worth investigating i think

 

Let me post an update after 6 years
@DarkAlchemist; It indeed was the 1/32 microstepping that caused the rare layer shifting. Changed it to 1/16 and never had a problem since.
This first printer was my only 3d printer and has been reliably printing for 6 years now!
No problems with it what so ever. Never had any loose belts or screws. In these years i only had about 4 nozzle clogs. (original E3D V6)
I've made almost no changes to the initial design, only added a brass brush at the side to be able to auto clean the nozzle before printing.
(very handy to be able to move the nozzle some cm further than the left and right edge of the build plate )
Still, my favorite material to print with is ABS, but i'm shifting towards ASA now..
I always print on capton tape on the glass bed, ABS stick very well to it (wipe it a bit with some 400 sandpaper and it's good for lots and lots of prints)

Note;
I'm close to completing my second build, a coreXY printer with direct drive extrusion which i can fully enclose. I wanted to use 10mm linear rods and linear bearings. That was a disaster. I tried multiple ways to get the build plate moving up and down reliably and smooth, and eventually i ditch these linear rods completely and used v-slot wheels again. These things are so easy to work with and so **** smooth and accurate!
