Does anybody had problems with Colorfabb HT? Won't stick well on buildplate :(

I have tryed lots of prints, with support print were needed, and after 4th-5th layer, the print start to unwrap especially under the support.

I m printing with 260 degrees, 100 d. buildplate, 60 mm/s print speed. I had the same problems with 0.4 and 0.8 noozles.

Fan speed 10%, Flow 100%.

I have tryed w/wo glue or hairspray.

Any suggestions will be welcomed!

I think they recommend 100 to 110 for the HB temp so maybe give 110 a go.

    Up to 120 deg. At what temperature are you printing? Without having it tested on HT higher temperature for the first layer usually also improves adhesion.

    I don't think 10 degrees can have such a big impact ....anyway 100 degrees bed temp is the max bed temp for ultimaker 2+ :(

    For PLA a difference of 10°C in bed temp can make a huge difference in bonding: 60°C is optimal and very strong. At 70°C the model becomes too flexible, so corners can be peeled off the build plate due to warping forces in case of difficult models. At 50°C bonding is clearly less strong, and a few corners may start to lift. At 40°C models may suddenly pop off halfway the print. At 20°C there is no bonding at all. At least, this is my experience, but your's may vary if your circumstances do vary.

    For other materials, temperatures will be much different, but I think the same effects will play. You need to find the balance where the bottom layer of the material gets a little bit soft, but not too much, a bit above its glass transition temperature.

    I would suggest testing this on a small test design, so you don't waste too much time and filament.

    If you created the design, or if you can edit it, you might also try to create the supports manually, or at least their bottom layer. If the bottom layer of the supports would be a solid layer of let's say 0.2mm thick, it should stick much better than individual lines.

    Yup, I was thinking to try also manual support. Thanks!

    I print HT with bedtemp of 80˚C and PVA glue on glass or use buildtak.

    Colorfabb also recommend using buildtak..

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
