    Flow sensor for the UM2+ (and even perhaps for the UM3) - Call for pilot users

    in Third party products & modifications

    Posted

    Has anyone with the filament sensor tried it with a Bondtech DDG extruder and a UM2+?

     

    No matter what I try or is suggested for me to try the flow rate just drops down until it gets to 0% using the move menu. 

     

    Steps climb as I turn the dial but flow rate always drops to 0%. 

     

    No no issues with printing when filament sensor is not connected. 

     

    Any ideas would be greatly appreciated.

    So I guess you are loading the filament manually, right? So do you push the filament forward enough that the end reaches the nozzle? I mean it could be the case, that your printer is working fine, but it takes some time until the filament gets to the end of the nozzle because you haven't pushed it enough forward. Try if you have the same problem when you load the material via the menu.

     

    I have tried that as well because when doing the factory reset to stock firmware it runs through the first time setup wizard and one of the steps is loading the filament.

     

    Its odd because even when I prep the filament by manually feeding until filament starts to flow and it prints the robot fine, next print it will start to under extrude again.

     

    UM2+ Under Extrusion

    Hello all,

     

    I'm been fighting with under extrusion on one of my UM2+ printers. Things I have tried.

     

    1. Changed the nozzle (replaced with an Olson ruby from another working machine)

    2. Taken apart the print head and cleaned out any debris

    3. Replaced the PTFE Coupler (I could feed some resistance when pushing filament through)

    4. Cleaned the inside of the Bowden tube

    5. Taken apart the extruder and cleaned debris

    6. Set the tension on the extruder to various levels between minimum and maximum tension

    7. I've reset the printer to factory (a few times) and loaded Tinker  V18.11.1

     

    I am just trying to print the Ultimaker Robot from the SD card.

     

    What I've noticed is that the printer will warm up, try to extrude some filament before starting to print (nothing comes out) then starts printing with no filament coming out. When I go to Maintenance -> Advanced -> Move Material and manually extrude by turning the wheel it takes a couple of turns but then filament starts to flow without issue.

     

    The only thing not stock about this machine is a printed lever for the extruder to allow for manual filament changes.

     

    I can see the marks on the filament showing that the extruder is biting into it.

     

    Any suggestions or things to try would be very welcome.

    UM2Go firmware doesn't exists yet, but should be doable with a bit of extra work...

     

    Basically: the growing count of different modifications to each printer variant is a recurring challenge. Even the UM2Go can have an Olsson block, a different feeder, a heated bed, a second extruder and so on... That's the benefit of open source hardware.

    There's no 'one-for-all' firmware but there's always the possibility to modify it - that's the benefit of open source software (i can not stress it enough... ?).

     

     

    Yep I can understand the amount of possible combinations with the various mods that can be done. My UM2GO as the Olson Block/iRoberti Feeder/Meduza Upgrade kit and a heated bed :). Thanks for the firmware to make that all possible :).

     

    I'd be happy to try the filament sensor with my UM2+

    What happened to Ultimaker 2 go ?

    I've got a UM2GO that I purchase earlier this year. Its a fantastic little printer. 

     

    Upgraded it to with a heated bed, meduza + iroberti feeder, door kit, 40W heater and an Olsson block. One  additional thing I like about it is that it shares most of the same parts as my UM2+ so any spare parts can be interchanged in a pinch.

     

    Works good as a second printer to print off smaller items while my UM2+ works on bigger/longer jobs.
