    I was actaully thinking about using silver based thermal paste or just some kind of thermal paste. Cram some in the thermister hole and then push the thermister in the hole.

    How to calculate stepper current.

    I emailed the company, Alunar, and asked them for the spec sheet for my control board. I don't think I'm going to get it. They sent me a spreadsheet with a bunch of info on it but there's nothing on...

    Thanks for the info!

    Ok so I have to balance the viscosity and speed of the print. I've been printing with a layer height of 0.2 lately. I'll try 0.3 now.

    Also, I have my retraction distance...

    Awesome advice. I already rounded the bracket. I also decreased the size of the holes so that they are more like pilot holes instead. I can easily drill them out later.

    Would it be better to...

    One more thing.... How do i keep the machine from infilling very small areas. I set the parameter for minimum area of infill, or something that, as 8mm^2,...

    Whats a typical flow? Right now i am printing at 120! When i was printing at 100 it appeared that the extruder was starving for material.

    Ill mess around with it more and see what happens. Thanks.

    Yea, printing on it's side is the way to go. I was printing it the other way just to see what the outcome would be.

    As for speed of the print, im actually printing them slow. Wall speed at 15,...

    Can you please critique these prints?

    This was my first print. Not good. I think I had bad retraction settings.

    I turned off my retraction and printed this one. Much better, but not as good as I would like it to be. I am having...

    Thanks for the information. I will check my thermister. Ever since the incident I have had to run the extruder hotter than I had to before. It might not be that hot, but that's what the display is...

    So I finally got the print printing again and I'm not quite sure it's the same. The quality appears to be where I left off from the other day with messing with the settings, but I'm having to run the...

    And don't forget to specify the units, during the conversion, to millimeters! That is if the model was built using standard units:)

    So I was messing around printing for the first time early this morning and everything was going fine until the thermister came out of the extruder. I have no idea how it happened. I probably bumped...

    Ok. I figured it out, but I'm left with another question. So, in my 3D software I built this bracket that's basically 1" x 1" x 0.5". When I opened the STL file in Cura, the object is only 1mm x 1mm...
  19. I'm new to this and have some questions about how small is to small with 3D objects.

    I had built this 3D model of a fairly simple L Bracket. It's small but not ridiculously small. It's a 1" even leg L bracket that's, for the most part, 0.125" thick and it's thinnest area is 0.0625"....

    Ok. I tried that. I lowered the voltage to 0.4v and even lower. I raised the voltage as well, as high as 1.4v. They still don't want to move. I lowered all the pot to 0.4V to see if the X and Y would...
