THANK YOU JHINKLE FOR THIS!
I've been printing for 8 months with a VERY hard to move head. I was 100% sure that my printhead wasn't making my small rods exactly 90 degrees (because I was unable to get my large rods truly perpendicular), but everyone said it was unlikely that the printhead would cause that.
I will try again now!
Thank you...
It squared nicely once I got the rods in the print head to be 90 degrees.
I loosened the print head's clamping screws and the adjoining bolts. The print head was still a very solid and no flexing anywhere was perceived.
Using my drawing of perpendicular lines and the rods as lever arms, I attempted to get to 90 degrees.
I felt nothing move at all. but after a couple of times on the rods applying force in the correct direction, the rods measured 90 degrees. I felt no movement -- but it moved.
With the print head rods now at 90 degrees I inserted the print head into the printer.
Set belt tension and placed the alignment squaring tools.
Perfect square!!!
It only took 8 hours of pain and anguish figuring out root-cause and addressing it.
Now that everything is square WITHOUT having side forces applied to the bushing in the sliding blocks -- the head moves smoothly.
I hope this helps anyone else with a squaring issue. Be careful NOT to just force square by forcing and setting the pulley (as UM suggests) or you will not run smooth and your stepper motor will run hotter than required.

Im not much better. I printed 2 items and filament flow jammed. Trying to clear the head i broke mine.
Ordered replacement and still waiting for it to ship.

Is there anyone from SEA here??

Shipment ???

this spam looks automated... if so, simple tools
like akismet could be added into the forum code to solve the problem once and for all, automatically.
afaik, using akismet just requires adding a few additional lines of code

if we have a cad drawing of the desired nozzle I could check up one of the local CNC guys here in Asia to see if they can do a prototype...
-
i'd support this....!
How much would an actual proof of concept cost?
Im sure we gather lets say 50 people together who each contribute say $XX for the prototype, we'd raise enough funds to get a prototype made?

Hi daid, thanks for your suggestion.
Laser cutter does sound interesting. Which models might you be considering?
I was also thinking of a 3d scanner... Would really save time!!
-
Oops my mistake~ Yes 0.2mm radius i mean..
-
For me it was the wooden box and super cool logo.
And of course the fact its a great printer (pulled the trigger right after seeing ddurants 0.02mm yoda post).
-
Ah you are right...
So basically because the "line of plastic" that is printed is 0.4mm (due to nozzle size), this means that sharp corners will never really be truly sharp, but would have a 0.4mm radius to them?
-
To add, the reason why I am asking this is because I am thinking of getting the UP Printer while I wait for my Ultimaker to ship (just placed order).....
-
Anyone here have the UP Printer?
Apart from its "ready out of box" nature and less tweaking required, is there any other reason why an UP Printer would be better than an Ultimaker?
Thanks!
-
it wasn't critism, more suprised that it can go as accurate as a lathe
In the Z direction that is. The X/Y direction stil lay down ~0.4mm width lines, so you can get some "rounded" corners, but this isn't visible at all with organic models like the Yoda.
Hi Daid,
is the X/Y 0.4mm limitation due to nozzle size? Or is it due to stepper motor precision?
Thanks!
-
0.02 mm ??
thats better than most lathes or mills can do
I ordered mine last weekend. I am planning to build some rc vehicles, starting with a T34 tank (specially printing the tank threads should be a blast) and a submarine to play with in the pool
Thats what i read here:

Check out the yoda model... amazing finish!
-
SAME HERE!
I was initially looking at makerbot, UP printer, kickstarter printer....then I saw dave durant's post about Ultimaker's layer resolution (with all the amazing tips).... 0.02mm!!! Then i pulled the trigger.....
My wait starts now... sigh
Hotend Heat Up Intermittent Lag
in UltiMaker 3D printers
Posted
Hi guys,
I have a UM1 and am facing an issue with hotend:
--When i start print, I manually push up the temperature to 200c (controlled via laptop).
--However, it usually takes sometime before it actually starts heating up. So on the temperature graph in cura, there will be a long flat line (at room temperature), then suddenly / randomly it will heat up.
Sometimes everything will be fine. I raise the temp in CUra, and it heats up immediately.
What's the best way I can I can trouble shoot to see what the problem is?
Thanks!
