Hey guys,
Feel free to share here the tips and tricks you discovered while printing the Ultimaker test print!
Hope it could be beneficial to everyone

The first print looked good on UM2, but failed to spin. So just releveled the bed (it printed a bit to far in the bed) and adjusted the flow to 100% (my default was a bit more). Another attempt is started. The first few layers seem to be ok now. Let’s wait 2 hours…
Same here. Used the .gcode from the zip-file on an UM2. Can’t get it to spin.
Form what I read at Thingiverse: “It’s designed to fit onto the standard English hex size for screwdriver bits”
But my screwdriver bits are too small :(It’s designed to fit onto the standard English hex size for screwdriver bits,
Ok. Got it spinning. I hit each gear with the back of a screwdriver to get the gears loose.
Have to say is not spinning smooth yet. There is a point where it needs more force to spin it.
Have to find out what causes that.
Discovered something else:
In the PDF the quality settings are 100 micron. In the .gcode in the zip.file the qualtiy settings are 150 micron.
What settings does it have to be?
100 micron is 1,5 hour more printing time.
The third attempt did spin right from the start. This model was printed with 99% flow.

After the third try I finally managed to have one spinning nicely! I used the original red UM PLA, printed on a UM1 (with heatbed). I used the original gcode file, but changed the first line to
M109 T0 S194.000000
Watch the first layer, don’t print it too close to the bed - otherwise it just squeezes out.
Good luck!

Did you use the original gcode file?
Hi WebfinityDesign, I did use the UM2 gcode file that was provided in the zip-file.
The only things I changed: 1- bedlevel adjusted so the first layer is not too squished in the bed; 2- use 99% flow, so the layers do not interact (much).
N.B. After the last print did spin right from the start, I read this blog and managed to make the second print spin also. Banging on the gears with the back of a screwdriver and using a hex tool finally convinced the print to spin. this one has more resistance, while the 3rd print is kind of loose.
Tried one with 99% flow, but it had some underextrusion and a lot of play between the gears.
Finally I have one spinning nicely without resistance.
I used the provided gcode file, 220C and bed-temp 55C

Hi @WebfinityDesign,
150 microns is fine as well. I will correct that in the PDF. Thank you for noticing.
Best,
Hi everyone,
I have some problems with the gears test with my Ultimaker Original in PLA Ultimate-Blue. The problem is with the printing result that the gear teeth are printed together. I put all the pressets of the Ultimaker Manual, the .gcode and doesn´t work. I ´ve tried three times changing some pressets with best quality but no way. What can I do?
Thanks in advance.
With kind regards,
Raphaël.

On a UM1 it was a challenge - a mix of speed and temp to get the support to print properly while not sticking everything together.
I print on glass (cold) with colorfabb pla/pha and found for a reliable spin I needed the first layer to ‘just’ be touching - more of a bead than a smoosh and slowed it down to about 75 as the 100 was not letting the support print properly at 210degrees - in fact I think that is why the 1.2 mm top/bottom layer is important because I normally do a way thinner layer than that.
but no one looks inside the model
Took a few apart that did not work and the ricky one was the outside to cog - which was well stuck in early tried, but the centre cog was free - now having done a few (wanted to check I could repeat it) i know that when the firstlayer is printing if the outer cogs touch the outer edge then it will not work - so can abandon after the first layer, adjust the flow (I am using 98%) and start again.

Hi James,
First of all thank you for your help, i´m very grateful.
I tried to mix temp and speed but i haven´t got (like 205 degree and 70 print speed). Anyway, when you talk about adjust the flow (in your case 98%), what do you mean? I tried to find this pressets in cura but I haven´t found! :s
Thank you again for your support.
With kind regards,
Raphaël.

First print worked totally fine. Just reduced the nozzle temperature to 210°C and the print speed to 50% then using the original UM2 gcode they provided.
Works like a charm…
