[I am having some issues on my UMO+]

Hi gr5,

 

Thanks for reply. 

I checked all screws on pulleys and motors and YES all screws for motrs and set screws on pulleys were a bit lose.

 

I also checked on feeder as you mentioned I tried pulling hard on the filament and it was pretty okay but I made made it tighter, by tightening the spring on the feeder a bit. my filament always had some teethmarks from knurled bolt. 

 

About settings in Cura:

I am using corse quality print settings and modified few settings under it. 

When I started printing for current project after few pieces I changed filament and then after few more pieces it started giving me issues.

 

I am currently using setings that I have exported from Cura and attached it here.

Basically layer height is 0.4mm, line width is 0.4mm and speed of printing infill is 60mm/sec printing temperature is 200deg C.

according to formula you mentioned volume is 9.6cubic mm and may be the temperature of 200deg is not enough.

 

Should I change tmperature and how do I calculate what it should be?

I am printing quite big pieces so changing print speed will result in more printing time.

 

I think my teflon part should be okay as I havent print a lot yet.

 

Thanks for your help, I really appreciae it.

[I am having some issues on my UMO+]

Hi, I have Ultimaker Original Plus. In last week I have printed almost 40 hours approximately 5 to 6 hours prints.

I noticed some problems in last few prints that were made.

1. infill is not overlapping with Walls in some areas, it got worse in the last print that I had to stop. (pictures attached)

2. parts are way off in weight then what cura shows.

3. printer also makes different noise thhan what it sounded when I started the forst print.

4. In the last print I also noticed that home for X and Y was not correct. (something went off may be missing steps by motor?)

5. strength of the print is also not good. (I guess if other problems are resolved this will resolve automatically)

 

Do I need to recalibrate my printer? if yes what all things should I recalibrate?

Should I dis-assemble and reassemble the printer again? (I personalyy will not like this option but if needed I will do it)

Can there be answer to my problems in timing belts and pulleys?

[more power to cura]

Thanks Framar I saw it online how to do that. 

[more power to cura]

I was thinking about, if there can be selection on cura when you can take a cross section and specify density of infill required. 

like some joints where infill desity can be higher. or is there something like this available?

Thanks Geert_2,

I will try to print something on the glass plate itself and see how it work

[Top layer is smooth and Bottom layer is not and looks ugly]

Hi IRobertl,

Thanks for your reply.

I understand what you are trying to say.

Please check pictures below. This was my earlier print with Raft as platform adhesion type.

In this also Top and bottom layer looks different. Different parts were printed and assembled.

In the picture red marked faces are bottom layers, blue marked face is top layer and black marked is portion of Raft face towards build plate.

Can this be because of distance between bed and nozzle?

[Top layer is smooth and Bottom layer is not and looks ugly]

Hi All,

I need help in fixing my problem regarding bottom layer looking ugly.

Top layer is smooth and perfect. and it feels like bottom layer lines are not merged.

,

Layer height 0.1 mm; Bottom/ Top thickness 0.8 mm; Initial layer thickness 0.3 mm; bottom layer speed 30 mm/s;

Bottom was printed on the support structure. But I have seen similar effect when I print it on the Raft as platform adhesion type.

Thanks neotko.

First thing I broke my Derlin pin so I added a plastic washer (it works good holding the knurled bolt in its place.) yes as you mentioned it might push the bearing I will pint a new Derlin clip as soon as the printer starts working this is just a small hack.

I think the video will be helpful as I can see how it is setup. The pin which slides down to lock the plastic assembly is what i did not do.

Thanks I will inform about what happens after the setup.

Hi Guys,

I have attached pictures of the material feeder.

Now I am getting a problem with the plastic part not giving enough pressure to the filament.

If I hold it with my fingers tight enough then it works.

What do you suggest, I should do to add more pressure on the filament?

Thanks in advance for your help.

gr5 - I have used a m8 washer between the gear and cap nut, as mentioned by tommyph1208.

and also I removed the top plate which is engraved Extrude. now things are okay. I can see gears mating quite well.

I also found a perfect size of a plastic washer at my work place, cut a bit of plastic piece from one side to fix it in the place of plastic clip. it works like a charm. now it looks like it is complete. I will post couple of pictures.

Thank you guys for this help.

This community was also one of the reason to buy Ultimaker

Thanks tommyph1208,

I know about function of the pin which I broke. I was looking for a circlip to mount on it.

Washer between cap nut and normal nut is a good idea :)Thanks.

I will try this today and see if it works. Thanks for your help

Hi tommyph1208 and gr5

Please check pictures. I have another issue, I tried assembling and disassembling the feeder few more times last night and I broke the pin (picture is attached). do you know where can I get this pin?

[Need help for Material Feeder assembly problem for UMO+]

I have put the feeder together, the first problem I got is that the outer gear engraved with extrude is touching a screw head of part 10D. So I assembled the material feeder again after pushing ball bearing and 8mm nut a bit further.

Then the second problem I am getting now is that the wooden gear does not make full contact with the plastic gear on the motor shaft, there is about 3 to 4 mm gap.

Any suggestions?

Thanks guys, but yesterday I already bought my UMO+

Hi,

I have made my Prusa i3, I keep on running in to problems like layer shift, and Z layer height problems. Plus quality of the print is not good at all. I cant even print parts more than 40 mm in size.

Looking to buy an UMO+

Any suggestions are welcome.

Hi, I have couple of questions.

Why are you selling your printer? Is there any problem with it?

If there isn't any problem with it then I am interested buying it.

Can you send it to the Netherlands?
