    • RE: Fans vs Berd-Air

      If you don't want the noise associated with an air cooling pump, there is an alternative that combines the benefits of an air pump without the noise, called the tusk air cooling. @mhackney has created good information on this: https://www.thingiverse.com/thing:2445660 http://www.sublimelayers.com/2017/03/the-tusk-fan-shroud.html

      I'm running a brushless air pump I sourced on aliexpress that came with silencer mufflers, as the the 'berd-air' pumps are brushed motors.

      A disadvantage with both the brushed and brushless motors, is they get extremely hot, hot enough to where you can't even touch the motor for more than a second.

      @gavatron3000

      Thank you for being a backer. I noticed with the amazon sheets and Prusas is that the texture is pretty coarse; maybe that is part of the issue. I've had people using them since July without issue.

    • 0.36ΒΊ stepper motors

      Is it possible to use Oriental Motor 5 phase bipolar stepper motors, assuming I build or buy the correct driver for them with the Duet? These steppers are 1000 steps per rev.

      I guess specifically I should ask @dc42 what your opinion is on these motor specs for use in a 3D printer if they would be a good fit or not?

      They have tighter manufacturing precision than even 0.9ΒΊ and 0.72ΒΊ steppers, so they should have a more accurate non accumulative step accuracy. They could be driven at lower than 1/16th microstepping or even full steps if necessary.

      Thank you!

      Update: we are now offering sizes up to 350mm and have lowered the costs of rewards! We have streamlined the reward tiers to make it less cluttered. You can also buy just a flex-plate now, whereas before we required the purchase of two at a time. ☺

      @klcjr89 hope it will succeed πŸ™‚

      Also - Can you share an image of how the underside of a print looks when it is printed on the surface? πŸ™‚

      Will this image suffice? πŸ™‚

      Here are two new images I took today. One shows the beautiful, uniform texture of the coating, and the other is a MK52 sheet I also made today.

      No plans for logo; it makes production much simpler and a more aesthetically pleasing product πŸ™‚

    • RE: Heater Fault, Slice Engineering Mosquito Magnum

      The Slice thermistor has extremely high resistance at low temperatures and will report as min temp on most firmwares using standard thermistor tables. The table linked here needs to be defined:

    • RE: New bed, from scratch.

      @bearer said in New bed, from scratch.:

      I can't say I got very scientific about this, but seems the magnet doesn't care very much if there is air, cardboard or aluminium between it and the steel sheet. And even at 1mm gap a handfull magnets provide ample holding force (or so I would think)

      But I've been told I can have the 120C/250F magnet sheet "smuggled" to me in a couple of months, so I'll skip trying to mill out pockets for magnets this time around. Mostly because the larger magnets would end up having the heating wire pass directly over them and not sure they would enjoy that despite being rated for 150C.

      Used "704" to tack down the heating wire, clamping each row down to try and get a good thermal bond, covered it all with high temperature silicone, a layer 2mm ceramic wool and a sandwich of silicone, fiberglass and aluminium foil. Will see how durable it ends up being. Also put a 120C thermostat, a 150C thermal fuse and PE bond on it, hopefully that takes care of the health and safety checkboxes:)

      6 minutes and some change to 20 to 100C, phone died while recording so not quite sure.

      Did you check out our Kickstarter? We are offering 150ΒΊ C magnet and PEI coated spring steel; might be a perfect fit for your bed! πŸ™‚

      @devleon I got it new old stock, so wasn't too bad πŸ™‚ If the idea works, the manufacturer has volume price discounts!

      @devleon The parts were very expensive, which always seems to be the case with any prototype project I undertake haha.

      The heart of it is a transducer, or known as LVDT in the industry. πŸ™‚

    • RE: Fillament-thickness sensor

      I am working on a sensor that measures in more than 2 axes and should eliminate all under and over extrusion issues for good. It even has the benefit of allowing a user to use random diameter filament without having to worry about issues.

      Even good quality filament is far from consistent. It may be '1.75mm', but has an egg shaped cross section or non consistent cross section across the length of the spool.

      This also doubles as a filament run out sensor. πŸ™‚

      @underdonesushi said in PEI coated flex-plate system:

      @klcjr89 It would be a personal preference to not having the magnetic sheet 3M glued to the heated bed, but yes true. Awesome can't wait to see the next round, will that be kickstarter also?

      Hopefully we won’t need a Kickstarter again. We’re just trying to raise capital to be able to fund mass production.

      Larger sizes are coming in the future after we have capital. You also don’t need embedded magnets with the entire surface of the magnet sheet.
