[Can I use a smaller nozzle for a high resolution model?]

Got it! I will try once the nozzle is ready. Thanks a lot!

 

Yeah there kind of is. but its kind of speed and part related.

If you are installing a 0.8mm nozzle It generally means that your not really wanting high details, just fast prints. Most details get rounded off a bit and my last 0.8 nozzle print was at .25 layer and came out pretty good.

For any nozzles smaller then 0.4 you can get a finer details and can lower the layers quite a bit but you don't need to lower the layer heights much. 0.08mm layers look the same on 0.4 and 0.25 nozzle, you just end up with less rounded edges. Things like lettering end up really clear where you may have had gaps if it was 0.4 nozzle.

Angles print better with lower layer heights but overhangs print better with higher ones. How long prints take also have an effect. So its really part dependent.

The new cura which will hopefully be out of beta testing soon is really good for setting up print profiles. So you will be able to make lots of different ones for different nozzles and different situations.

 

[Can I use a smaller nozzle for a high resolution model?]

Thank you Labern. I will try a smaller nozzle later. Now I generally use 0.4 nozzle with the 0.1 layer height. Is there a suitable layer height for each different nozzle to achieve a good result? For example the 0.05 is good for 0.25 nozzle and the 0.2 is good for 0.8 nozzle.

[A question for OLSSON BLOCK]

Great! Thank you Labern, I will order one:)

[A question for OLSSON BLOCK]

Now I am using Ultimaker 2, I am just want to know where can I get a new OLSSON BLOCK. I want to buy a new one on line. Thanks in advance!

[Can I use a smaller nozzle for a high resolution model?]

I am new in 3d printing. Now I am just using a 0.4mm nozzle which is fine for some nomal model. But if I print some more detailed models such as the Eiffel Tower. The result is not satisfied. There are many thin parts in it. So I am curious whether a smaller nozzle (0.25) can make a good result for it.

[Sometimes the filament is broken.]

Actually, it does not often break. But it is really aggravating :( . Since it is impossible to wait beside the printer all the time until the printing is finish, so I am thinking whether there is a way to pause the printing ASAP when the filament is broken.

What brand is it?

If it happen often, you might need to pay attention to how you store your filament

 

[Sometimes the filament is broken.]

Since I always print some large models which is time cosuming. But unfortunately the filament is broken today, so I have to print again. I just wonder is there some methods to prevent the filament from broken.

[Can ultimaker2 print this type of model?]

BTW, for the image I paste above, I just lay it flat and print, the final result is very poor...

[Can ultimaker2 print this type of model?]

Today I try printing a bridge which is very complex. In this bridge, I add many supports. Also some parts are too thin. So I am not sure how to print this type of model by ultimaker2. I also want to print a Eiffel Tower, but I am afraid the final model will not be satisfied, for there are too many thin parts in it. How to set the parameters of cura if I want to print it? Thank you!

[How to programme the power on image?]

Firstly Thank you tinkergnome for the answer. I just notice that sometimes the lcd cannot show the logo correctly, not each time，the image cannot be fully shown in the lcd occasionally .Also there is image Dithering sometimes.So I look into the firmware and try finding the reason. I did not change the firmware. I guess if the code is correct, maybe there is a problem with my lcd screen. Not sure whether my thought is correct.

[How to make the top layer smooth？]

thank you for the answer. I already set the top layer to 6. I will have a look at your link. Maybe there are some more issues during my printing.

[How to programme the power on image?]

When the machine is power on each time, we can always see that there is a large logo “Ultimaker” on the LCD screen. I just have a look at the firmware and find that it is programmed through a so long code as following. I am just a little curious why the long code indicate the big logo. What code is it?

[How to make the top layer smooth？]

Sometimes I print modules with large top layer. To make the top layer flat, I set the bottom/top thickness as 0.1mm, the bottom layer is very smooth, but the final model is not very satisfied. Is it possible to make the last layer smooth as the bottom layer after change some parameters of cura?

[Did the ultimaker support shut down automatically？]

Hi Labern，

One more question.:)I look into the circuit diagram of the mainboard v2.1.4. I found the big change is that the 5v small fan is under the control of the microprocessor. Also there are some resistors added to the output of the A4988, right? I am a little curious what is the reason of it? Besides these 2 differences, there seems no big change between the v2.1.4 and the v2.1.1. is that correct?

 

yip, that one or UM2 extended

 

[Did the ultimaker support shut down automatically？]

In this folder Ultimaker2Go/1546/1546 ultimainboard V2.1.4 electronics, right?

 

I see. Thank you Labern. Then where can I find the circuit diagram, I want to have a look at the 5v fan connection.

 

V2.1.4 is the new board. its not supported on the older ones

[Did the ultimaker support shut down automatically？]

I am using the ultimaker2 and I found the mainboad version is V2.1.1. From the diagram, I found that the small fan is connedcted to 5v power directly. So it is not under the control of the microprocessor. So how to make it turns off when it cools down to 40deg. There is a update for the mainboad after V2.1.1 , right?

 

Yes the small fan can run for hours.

how old is your printer? the new ones the small fan turns off when it cools down to 40deg

 

[Did the ultimaker support shut down automatically？]

Yes, I found that the motor , the hot end, the hot bed and the PWM fan can stop working when the printing finish, but the 5v fan working all the time. So I am not sure whether it is ok for this fan work for a so long time.

Thanks,

Vincent

 

I think Labern's only talking about the LED's shutting off, not the printer itself.

However it's totally fine to leave it on. Once the print is finished the heated bed and printhead cools down and the stepper motors turn off, so essentially its idle, like a computer in screen saver mode. It's on, but it's not really doing anything.

I leave prints overnight all the time and come back to a finished print in the morning (or over a few days...)

 

Thanks for your long explaination. It is really helpful. You just mentioned that you can have it switch off after a set time. So how to do this? Does the ultimaker support this function or need I  modify the firmware? I just do not want the machine power on all the time until I turn off it. Thanks a lot!

Thanks,

Vincent

 

No It doesn't have this function.

When the print is finished it will cool down but stayed powered on.

If I am to leave it and the print will finish when i'm away then I normally turn the LED's off. this can be done when the machine is printing under TUNE, and set LED's to 0%. You can also set it so the LED's turn off automatically when the printer is finished or to do different things under expert settings on the printer.

or you could get a power point timer and have it switch off after a set time. I always add an extra 30mins on the timer just encase.

 

 

 

[I cannot set the temperature of the hot bed.]

Very happy to see your quick answer again. I have found the setting on my machine. Thanks again!

Thanks,

Vincent

 

on the UM2 this is done on the printer its self under material settings not in cura.

You can create a new material profile and save a different temperature under that profile or you can edit a current profile on the printer.

If you want to change it in cura the you need to change the Gcode Flavor under machine settings to RepRap.

[What is the voltage of the PWM fan?]

Hi ,

I am a beginner of the ultimaker. From the circuit diagram of the ultimaker mainboad, I notice that the PWM fan and the PWM led use the voltage VCC/2. So what is the value of VCC/2?

Thanks,

Vincent

[Did the ultimaker support shut down automatically？]

Hi,

Now I am using ultimaker 2 to print some large models, so the printing time is very long. I am just curious whether this machine support shut down automatically. Then I can leave it printing instaead of waiting until it finish.

Thanks,

Vincent

[I cannot set the temperature of the hot bed.]

Just a short question of my Cura 15.02.1. I cannot set the temperature of the hot bed as following. So I have to use a fix temperature each time. Did someone hit the same issue as me? Thanks in advance!

Thanks,

Vincent
