    I hate to start a new thread and the old one´'s about this subject is close to 10y old so I´m going to ask here. And again I am tagging you @gr5 .. Sorry!

    So I´m calibrating my extruder, but I cannot get it to extrude when I write Gcode and put it on the sd card..

    code : G91 G1 E100 F300

    Wrote it in notepad ++ with G-code marlin language and moved the file to the sd card. All it did was homed axis and then said finished.

    same thing when opening the gcode with cura and export to sd card. What am I doing wrong?

    Machine settings in cura is "g-code flavor" ultimaker 2+

    Thanks guys! I figured it out when I assembled my um. Both 5mm spacers goes to the front of the 8mm Y-axis for anyone wondering.

    The new Z stage bearings was a great "upgrade". I bought a new z nut aswell and made a anti-backlash nut with a spring as someone posted on a other forum. The bed vibrations are gone now! 

     

    I still have some problems going on that I have not figured out yet. My bowden tube is leaning to the right and I'm experience some under extruding still. Even with all new print head parts. Perhaps it's due to the bowden tilting to the side..

    I have ordered a new tube so hopefully that will fix it.

    I see the benefits with not using the "change filament" option. You always get a clean nozzle when you change the filament. I'll give it a try next time I change the material..

     

    Well I'm from Finland so I doubt you have shipped me anything in the past 😅 

     

    Perhaps my bed will be more stable after the linear bearing swap. Time will tell.

     

    Thanks for your opinions!

    Hi gr5!

    I´ll sure be getting a Um2+ feeder if I ever in the market buying another one. Yes I have the QR version. I don´t really understand what you mean with the pain to open and close? The quick release system perhaps? 

     

    3dsolex was nice to send me a ruby nozzle as a gift a few years back, I havn´'t tried it yet but sure will when my printer is back up and running. 

     

    I´ll be doing some research if it´s worth stabilizing the bed somehow. What do you personally think about it?

     

    cheers!

    Hi @robson,

     

    I'd just thought about the same as @nallath, -but he was to fast..  🙂

     

    However, I would also mention those two shaft 6 mm for the head included with the bearing.

     

    So, I'll say go for it, -as it's the best refreshment you can do for your UM2 (+) perhaps..

     

    Good luck

    Torgeir

    Thanks for the tip, but since I have a new feeder/extruder, hosuing for printhead,40w heater and sensor, + 3d solex block I basically have all what they are offering.. except for the new 6mm linear bearing and rods. I checked my rods and they are straight, linear bearing are sliding well on the rods aswell so I don´t need the printhead upgrade kit.

     

    Cheers

    Hi Nallath!
     

    I have a 3dsolex block for the nozzle. Kinda like an olsson block. Same principle. 

    Bad linear bearings on Z axis makes it tougher to move up and down. it can get somewhat stuck at different places when moving bed up and down ny hand. Hence missing layer.

     

    I would need a video to show the vibration. Sorry to say I don´t have one. Here´s a vide on someone else (different brand printer) bud the issue is similar to this. not as much as in the vid but still.. 

    I´m not the only one with this problem. https://www.thingiverse.com/thing:2007717

    So my 6 year old ultimaker 2 has always been printing semi bad. Today I desided to pull it apart and rebuild it with some spare parts I ordered years ago. 

    I´m installing new belts, pulleys, bondtech QR extruder, renewing parts in printhead, and I´m ordering new linear bearings for Z axis rods. along with z nut[s].. Building a anti backlash nut as someone did over at endless-sphere using 2 nuts with a spring. 

     

    One thing that I´ve had problem with since day one is that the print bed is vibrating to the point it´s hard to print support (or just print above 40mm/s ) if I don´t go superslow. I´ve seen some people re-inforcing the bed with steel or alu U-profiles. 
     

    My question for this topic is basically tips for upgrades or parts since I`m already have it apart and don´t wich to do it again anytime soon.

     

    Regular problems with my printer :

     

    - Underextruding (Bondtech should fix this)

    - Missing layers (New linear bearings and z nut should fix this)

    - Vibrating print bed (Has nothing to do with how tight or loose the 3 springs are) Stabilizing it somehow would be the solution here. New linear bearings and anti backlash nut will probably help a bit, but I rather fix this then rolling the dice

     

     

    Any tips are welcome.

    @robson This is off-topic but I had a simmilar issue with the pulleys. They were not completely round either and I replaced them with some custom manufactured ones and.... it didn't change anything. If you have problems with printing round objects, at least I can say that it might not be related to the pulleys at all.

    If you have problems with round and square objects, post a new thread - I am sure people will step in to help with that. There could be issues like loose pulleys or slicing problems.

    Thank for the tip! I will creat a thread once I get my spare parts and are up running ( if those part didn´t help)

    Also my pulleys is VERY excentric. meaning belt will only be tight in one possition, turn it 180 degrees and belt is slack. Wich should have impact on moving print head in XYZ. Never heard a tooth skip on the belt tho.. Also it´s not just one pulleys but 80% if them. One of the short belts are affected by it..

    There's definitely some resellers on the forum; there's probably one on here closer to you than I am. fbrc8 is based out of Tennessee, in the US.

     

    We stock official spares of most parts at fbrc8.com. Even things not listed on the website, we usually still have in stock (like the pulleys). We just usually list the most common parts on the site. 

    I´ve bought a lot of stuff from US lately and shipping was usually 36€ with ups or dhl. wich is actually not bad at all. Do you happen to have the following parts or can get them for me?

    1. Metal fan shroud horizontal version for UM 2/2+

    2. Upper plastic house for the print head

    3. Complete pulley kit

    4. The support axis tool for removing rod´s. It´s probably 3d printed but not sure..

    Yes there's only one reseller in my country. I actually bought my um2 from sweden since swedish is my native language and felt more comfortable buying and getting support in my native tongue..

    But I'm not too happy with them since I addressed that the pulley's was very excentric and would like a new set of pulleys, I got the answer that it wouldn't affect printing quality and I should just keep on printing. This was still when my printer was under warranty.. And now I need a new set since printing cylindrical and square object is not working out for me. So giving them money for something that should have been replaced under warranty doesn't sound right in my book. 

    Haha I realice I sound like a whining wiener here but principle are principle..

     

     

    However paying extra for shipping wouldn't be a big issues for me as long as I can get all the parts from one place. And shipping wouldn't cost me 100€..

     

    Any official resellers here on the forum? Ultimaker team members? Any one that can get me the parts here?

     

    Appreciate your help guys!

    Hello!

    I sent him a reminder yesterday. Will wait until next week befor I give him a call.

    I did print a couple of those fan shrouds from youmagine. Nice design but ofc they tend to deform while using higher temps. So I would really like to have an metal one. Also good to have all original parts if I ever tend to sale my ultimaker.

     

    Do you know any place where I could get good quality pulleys for all axels and the top plastic house for the printhead? 

     

    Thanks for your reply

    Regards

    I´m in need of some spare part to my ultimaker 2. Trying to get a set of pulleys and a fan shroud ( the fan shroud for ultimaker 2+ horizontal version) and I sent 3 emails over the past year to ultimaker.com...And no answer at all.. Realized there´s an official ultimaker retailer in my country nowadays and contacted him. He offered me a boundle set with spare parts for a fair price but that excluded the shroud and a tool I also want.  (the rod support tool when removing rods). Also there was so many parts in that boundle I had no use for so it would only cost me extra $.... Now another week has gone by without any further answers or help. This is starting to get on my nervs. It can´t be that hard to get me those part´s I need.

    Who shall I turn to to get the parts I need? I would very much want to get my printer up running asap. I will let next week go by because who knows. he might be sick or on vacation and that is fully understandable. But if that´s not the case. who shall I talk to? source 3d party spare parts even tho I payed over 2k € along with probably 500€ add ons? 

     

    Any help/suggestions will be appreciated

    Cura 2.4 Nozzle size options

    in UltiMaker Cura

    Posted

    Just set the "Line width" and "wall thickness" setting to a appropriate amount, and you are good to go.

    I just need to clarify this because I´m an idiot, and just started to use Cura..

    I got a model with 3mm walls, roof and flor. And want to print this with 1mm nozzle.

    Does it matter if I use .25 / .4 / .6 / or .8 nozzle when printed with 1mm?

    Line width : 1mm

    Wall thickness : 3mm

    Wall Line count : 3

    Top / bottom thickness 1

    Infill : 0%

    This should give me 3mm thick walls all around the model right?
