    Double print?

    in UltiMaker Cura

    Posted

    Would it be possible to get a warning from Cura when ArcWelder is enabled on at least an Ultimaker printer that does not support G2/G3 code?

     

    Looked almost the same as when I first tried that plug-in on UM3

    UM3 will not print with PETG ?

    Yes it will, no problems at all but I reccomend you print on PEI sheet, and on a flex plate, or order lots of spare glassplates. The adhesion of PETG is so strong it easily chips glass when cooling down.

     

    What Ultimaker is announcing is ready optimised profiles for their PETG, you simply have to make your own for your printer.

    No extrusion at last part of layer

    Looking at second picture and third layer (Z1,9) it seem to start at X75,762 and end at the same if I read the file correct. Gap is in the X-axis

    I assume the last G0 movement is wiping the outer wall

     

    Start outside layer3:

    Same part but arc welder enabled makes the code easier to read to me, knowing what is circular and straight motion.

    However, I did not save this as a 3mf file and might have moved the model so X and Y positions cant be compared but it seems to do the same:

    No extrusion at last part of layer

    in UltiMaker Cura

    Posted

    Material flow stops close to layer end and I cant find settings in Cura that might do this.

    Looks like excessive coasting but that is not enabled.

    Width are roughly 4-5 mm

    Smart Z-seam hiding is enabled so I get this at mixed locations, both inner and outer wall

     

    Any hints?

    Advice on Nylon G and printing with Ruby 0.40mm

    in UltiMaker 3D printers

    Posted

    I've done some Nylon with carbon fibre with standard 0,4mm nozzle and that came out with a superb finnish.

    Parts were pressurised to 5 MPa and connected to a solenoid that reached about 100°C so I wouldnt say material properties were compromised by nozzle size.

    Didi it first in PETG with carbon fibre but it got too soft after a while and deformed under pressure so I know material properties was under strain in that application.

     

    Maybe glass fibre is different, never tried that

    First, make sure the filament is dry. PLA isnt that sensitive but if the material has been laying open a longer time it helps to dry it.

    If you have an enclosure you can just heat the bed to 60°C and leave the roll on it a coupple of hours.

     

    As dmyth said, small parts can suffer from insufficient cooling if layer print time is short.

    If you already run the fans at 100% try to print a few more of your model at the same time. That will allow them to cool down better. 

    There are parameters in Cura that can control layer time as well but that is beyond my experience.

    Zoom limit?

    Try this setting to get your model sit flat on the ground plane:

    This is also a nice plugin I recommend, if you havent already installed it, written by Nallath.

    It will calculate best orientation for the model and orient it for you (you can change orientation manually anyway you want still)

    Arc Welder Anti Stutter plugin

    in UltiMaker Cura

    Posted

    I have started to try Arc welder but getting some weird 1st layer behaviour.

    Tried two different model and the result is similar. If you look at the picture you see a strange pattern that is neither in the model nor visible in Cura preview.

    First try I did was worse than this, broke off what was supposed to be a continuous outer wall. This one I let run and it seem to fill ok.

    Issue with PETg printing

    in UltiMaker 3D printers

    Posted

    I have done a fair share of PETG printing (20-30 kg) and has given up on printing on glass, it just sticks to hard.

     

    Have changed to printing on PEI instead and that does magic. No need to fiddle with glue or anything to get a good match.

     

    Do yourself a favour and get the flexplate system from Build-Tak makes removal so much easier.

    The PEI sheets have been good with most materials I have used (PETG, PETG+Carbon fibre, PLA, TPU)

     

    Mixed results with Nylon+carbon fibre, some good some got loose. Failure might be due to getting lazy not cleaning the PEI after every print since the other materials dont require that.

     

    They have a special sheet for nylon but I have not yet bought one.

     

    Dont use their standard build sheet together with automatic levelling if you are printing on an Ultimaker. They heat the print cores during levelling and that makes the core dig in and destroy the build sheet.  Learned that the hard way.
