    "HELP"

    like I explained yesterday, the linear stage did not move the platform to the upper 0 position. This morning I checked it again. It does not work.
    Something is wrong with the left side Rod of the linear stage. The cylinder (cone) is sticked to the rod and the motor will not move it. I released the cone and moved the platform manually down so I can inspect it freely.Tryed to move it bye hand to take it out and see if something is blocking from the inside. But it was impossible to take it out by hand. I took it out with a wood hammer and removed it from the top side of the machine.

    This Cone is to narrow in the inside (I tried to check with the other rod but even there it will not move (I made some new lubrication but definitely this rod is to small) 

    I was wondering if the platform had some defects too because of the middle screw (because yesterday when I type in the G28 Z command the motor was working at least 5 minutes and trying to push the platform upwards but the platform didn't moved) So I removed it but I did not realise that there is some kind of bearing inside (all the bearing balls are apart now.

    Please let me know how to fix the bearing and please arrange a working cylinder cone. It would be not difficult for me to contact th guys in China as I am in Hong Kong.

    Awaiting your fast feedback

    I have a problem with the linear stage.After 2 days of trying to make the machine work correctly, I printed 3 small objects when I typed in the command G28 Z the linear stage moved up around 5 cm and stopped moving but the motor and rod still moving.

    I was trying several tamest reset the machine but I think there is some mechanic problem.

    How canisejd you a video of the problem??

    Hi Rkundla,

    I saw you have experience in lost wax casting. Your results are beautiful! 

    I have a few questions, hope you can help me :-)

    1) What is the difference for lost wax casting between B9 resin and B9 cherry resin for the casting and the casted results?
    2) Do you always use the same resin for lost wax casting? If yes, which resin or mix (and mix ratio?)?
    3) Do you have experience with lost wax casting with small aluminium parts? (for industrial/mechanical purposes for instance). 
    4) I would like to use my Draken printer for lost wax casting especially for aluminium parts. Do you have advice or tips for me?

    Thanks in advance.
    Kind regards,

      Hi Lennart!

      Sorry, I just saw your message since it didn't come through the private message section.

      I haven't been able to print pure cherry resin because the projector is not powerful enough and the peel is touchy because of the viscosity of the resin.

      I print a mix of red and cherry to get more pigment which provides more detail. The current mix I am using is 3:1 red/cherry. I will probably move to 2:1 in order to increase the detail. I have used CastSolid resin to do a print and the results were okay, but in my test not as good of fine detail like the b9 resin.

      The only lost wax I have experience with is in precious metals and small sizes around 20^2 mm max.

      If you would use investment like Plasticast from R&R, follow the directions and burn out the b9 resin to their schedule, you should be able to get good quality castings. You do need to make sure that the resin print is fully cured. Any uncured resin during the burn out will damage the investment and ruin the surface quality. The b9 forum recommends a mixture of UV and heat curing (either in microwave in water or in a kiln/oven).

      For more specific information, you may need to search online for others experience with casting aluminum and any additional steps to help get a good casting.

      Regards,
      Ron

    Ron, it seems that there is 10 days delay to go with fedex while DHL is $30 more expensive but could pick/ship tomorrow (we can cover the additional shipping for you). Accordingly to your schedule, which one you prefer?
