Marlin going crazy?


Recommended Posts

Posted · Marlin going crazy?

I experienced something quite odd yesterday, I was printing, and suddenly my printing speed increased to insane. I had to abort the print because it caused the filament drive to grind into the filament. But I wouldn't be surprised if the print was happening at my travel speed of 300mm/s.

I tried starting another print, but it was still going at insane speeds, I had to reset the machine before it worked normal again.

Anyone else ever experienced anything like this? I was printing with RepG with the realtime control window open. I printed the same GCode with no problems after the reset.

    was there maybe a gcode m220 in the file...?! that sets the the speed in some marlin versions

    I'll check, I did do the print from "Slic3r" before this print. Might be related, so I'll check that GCode.

    Ok, more info. It's related to the realtime control feature from RepG. Once I click that panel open it goes all crazy. Not sure if RepG sends a M-code at that point, but it goes crazy, even if I put the speed down to 10% it goes crazy fast. It's only sending F180 at that point, which should be crazy slow.

    The strange thing is, the realtime control worked fine before...

    Hi All!

    I experienced the same behaviour with marlin (9f57cdd and 0ad9779). Every time I open the realtime-panel (RepG25/RepG26alpha, MacOSX) the printer behaves crazy at crazy speeds! I tried this several times and actually I can't use the realtime controls. Also lowering the value to low values (10%) has no effect......

    Best regards,

    I concur with the realtime panel bug. Its really annoying as you open it when you worry about your print, and this bug start to kill your print from then on... :(

    Marlin version is the latest one from Bernhards github. (used tortoisegit to update)

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
