    • RE: DIY Fan Smoother

      @zapta I received the board.
      The pump starts smoothly at 20% and is at full speed at 92%. Far better!

      Thank you very much...

      @zapta
      I'm interested to buy one too.

      I've got a 24v pump that don't like pwm...

    • RE: Belt driven Z =) (dropping problems ofc.)

      I had the same problem. My bed is stationary but the XY gantry moves up and down. I have 4 stepper. I went the counterweight route. I melted 4x1 kg lead blocks.

      I wanted to use some springs but the strength change with the position in z.

    • RE: Pictures of water-cooling

      @lael nope, no leakage. But in my opinion, it would be better to have a real fitting. I'm gonna change it soonish.

    • RE: Tinkering of building HD Voron

      @paulhew i have built a printer using this kind of design. You can build it without being overconstraint. But you need to think about each z axis as independant axis. My 2 y axis are fixed in the back and they are just put on the front z axis.

      You can't really make 4 identical z axis.

      But it's somerhing you can make.

      For my printer, it was easier to keep the bed stationary. 7kilos is enough...

      Copper tubing is easier to find than brass tube...

      @mrehorstdmd

      The tubing isn't copper in my watercooling, but it will be...

      But i need to find a way to solve the galvanic corrosion.

      @fma said in Z axis: ball screws vs belts:

      Does small gaz cylinders exist, like for car rear tail-board?

      Yep, you can find these in any length, but their power is different along the length.
      Think of them like a spring.

    • RE: Z axis: ball screws vs belts

      I went the other route, with belts and counterweights...
      1 kilo per belt.

      Works nicely, no more falling without power.
      I used brake cable for bike with wheels because the tubing had too much friction.

    • RE: 3D Printer Water Cooling advice?

      @theruttmeister
      I agree with you, the watercooling is overkill. You can have a single line with a 120 fan easily.
      I put a watercooling with a 40x40 fan on a aluminium heatexchanger for the hotend and the extruder. The temperature stays at 25 deg max.

    • RE: Mosquito vs water cooling

      As pump, the cheapest Waterpump found on ebay. 12v for computer watercooling.
      The cube is smaller and less powerful but is enough to drive the water trough 3meters of bowden tube.

      As tubing some tubes found at work and bowden tubes

      As connector, i used the pushfits for bowden or the 90deg found on conrad

      @fma yes i think i have it.

      What kind of files do you want?

      I work on catia

      With only a drill (and a screw), you could have a u shape.

      @fma

      Why have 4 pushfits?

      You could make a u shape inside your watercooling.
      It will reduce the flow but will increase the heat exchange.

    • RE: Mosquito vs water cooling

      Yup the red thing is a remote extruder.

      The watercooling on the corexy is just a 8mm aluminium part with 7 holes drilled
      A m7 for the heatbreak
      2 m5 for the pushfits
      A m4 to connect the 2 m5 holes
      3 m3 holes to attach on the carriage

      On the delta, the hotend is a maxiwatt with a homemade silicon sock
      And yes with a piezo as z probe

      Why you heat

    • RE: Mosquito vs water cooling

      In an enclosure, a watercooling is the best solution for me. A chimera might very large for a single extruder. I drilled some blocks of aluminium used with the e3d heatbreak.
      No more heatcreap with a very small block 15936391776921731898753787276774.jpg

      15936392269301246707830868041104.jpg

      All the parts in the watercooling are in aluminium
      The first block had a thermistor in it and the mesured temperature remains at 27deg in a 60deg enclosure.
      These blocks were made with a drill.

    • RE: Extruder temperature problème

      @JuL

      I had the same problem last week
      The problem was in the e3d connector. I replaced it and the temperature was back to normal.

    • RE: [HELP] How to use DueUI without a Duet using chrome

      Thank you very much,

      I'm on tracks.
      I'm modifying your file.
      I was looking for a way to modify the layout of dwc but your way is easier.
      Thank you again.

      I didn't have any apache server
