    Spring belt tensioner

    in Third party products & modifications

    Posted

    Hello all,

    Just want to share this, perhaps it can help someone.

    I'm designing a new frame for my UM1 from aluminium extrusions.

    When designing the XY clamps like the ones of the UM2, I ran into the problem that there's not enough space available in those clamps for a integrated belt tensioner.

    To keep those clamps light weighted, I needed to find another solution.

    Browsing the Internet I found some people are using springs of clothespins.

    I've tried that but my belts went to tight causing more resistant on movement.

    So I've been looking around if there are suppliers that sells those springs with less torsion.

    Finally I found one and ordered 10 sets but at high shipping costs :cry: .

    Because my new frame is a work in progress, I've replaced my traditional belt tensioners in my UM1.

    They work very well I must say.

    Hallo Marlot,

    Hier nog een mede nederlander die je wel wil helpen :-)

    Die 'ringen dingen' heten pulley's.

    Deze dienen goed vastgedraaid op de assen te zitten.

    Wanneer je de printkop met de hand beweegt, kijk dan of riemen in 1 lijn recht om de pulley draait, maw, de riem mag niet scheef gaan tov de pulley's.

    Stel deze zonodig bij.

    Zorg er tevens voor dat de riemen strak gespannen staan, slappe riemen hebben een negatief effect op de print kwaliteit.

    Wat betreft de ventilator, staat in Cura ingesteld dat de fan aan dient te staan?

    Standaard instelling is dat deze aan gaat na de 1e laag.

    Kun je wellicht toelichten wat er niet goed gaat bij punt 3?

    Mvg,

    Harold

    Hi Harold

    The cooling fan mount in your printer looks cool, is it available on thingiverse? Appreciate if you can share a link for download.

    Thanks

    Pay attention to Valcrow reply about hitting the slider blocks.

    Sorry to reply to my own post so late, but I almost forget about it because I made this post in June.

    Nevertheless, thank you Daid for your reply, I already use the newer versions since 13.06.4 where those support lines don't hit the object itself.

    I must say i really admire your work, I've programmed a few years myself an I know how difficult sometimes it can be.

    Keep up the good work!

     

    MIC-6 alu plate

    in Third party products & modifications

    Hallo Sander,

    Dank voor je reply.

    Die heb ik inderdaad ook gevonden, echter leveren zij geen MIC-6 aluminium.

    Ik heb tevens begrepen dat zij het aluminium knippen, hetgeen effect heeft op de vlakheid van de plaat.

    De bedoeling is dat ik rechtstreeks op het aluminium ga printen (met een stukje kapton tape ertussen), vlakheid is dus essentieel.

    Mvg,

    Harold

     

    Has anyone built an Ultimaker from aluminum instead of wood?

    in Third party products & modifications

    Currently I'm building a frame of aluminium extrusions for my UM.

    Intention is to reuse all the (non wood) parts of the original UM to the alu frame.

    I also build in a heated bed with alu plate, dual extrusion, UM controller and the possibility to close the frame to make some kind of heat chamber for printing with ABS.

    But all of that is a work in progress.

    Regards,

    Harold
