Re: Buying Nozzles

Been printing a bunch of glass-filled ABS. Compared an A2 hardened nozzle and an Olsson Ruby (both .6mm dia). Ran a bunch of Carbon filled nylon for another job and was doing well with the Ruby on the glass ABS. I tried the A2 nozzle on the glass ABS and got inconsistent prints - seems the nozzle wa...

Re: Faceted circumference

The settings will be in your STL export. I don't know F360, but other programs I've used display a preview of the STL. There should be some settings that allow you to create more facets. It's not going to be in the slicer.

Re: Has anyone done a 32bit upgrade to the N2 series?

A warning - I just learned that making a ribbon cable extension to between the Duet board and the Thermocouple daughter board is a bad idea. The communication protocol used on the daughterboards does not do well over any significant distance. I guess I've been lucky on my N2 - Thought the N2+ was go...

Re: bubble of build surface (Pro 2 )

I find PEI to be a much better, more durable build surface for ABS than BuildTak.
Never tried PEI on glass, so can't speak to how that might work. I've always had it on 1/4" aluminum.

Re: Raise3D ABS + XY Size compensation

Even in injection molded plastics, color has a significant impact on part size. With the same material, same color, a different material lot can result in print differences. Different moisture levels, there are all kinds of factors that come into play - some we have control over, some we don't. Your...

Re: Raise3D ABS + XY Size compensation

You might have a few things going on. Being too close on your first layer can create an "elephant foot" on the model - expansion at the build plate. Over-extrusion can also push out the perimeter where solid layers are being printed. Too much heat on the build plate can also warp the sidew...

I'm currently running a glass filled ABS. Changed to material with a different lot number - need to recalibrate. It doesn't take much.

Re: Dimensions not true

There are so many variables that impact the dimensional accuracy of a part. Anything that impacts how the plastic flows from the nozzle will have an impact on the final part dimensions, whether it's speed, temperature, layer thickness ... even the color of the material has a significant impact. It's...

Re: Dimensions not true

I use the SCALE number to scale models on the build plate. Double click on a model and you can CHANGE SCALING. Horizontal offset is on the OTHER tab. In IM you can also scale on the build plate. There used to be something comparable to the Horizontal Offset, but it appears that's been replaced by th...

Re: Dimensions not true

Here's the process I use for achieving dimensional accuracy.
I don't slice with IM, but the principals are the same. I normally can achieve +/- .1mm on dimensions large and small.

Re: Square corner problems

The problem stems from elasticity of the melted material and pressure in the nozzle as the printer slows at the corners. Running the prints at a slower print speed and/or reducing acceleration/jerk settings can also improve the corners. Linear Advance/Pressure Advance can address this without reduci...

Re: Layer Shift

You say the first layer was flat. Not sure what you mean by that.
Is the bottom surface of the failed print perfectly flat?

Re: Layer Shift

There are about 17 different things that can cause layer shifts. A few that come to mind are Condition of the gantry rods (lubrication, cleanliness). Speed, acceleration, jerk settings exceeding machine capabilities (either travel speed or print speed). Material collects on nozzle - drops blob on pa...

Re: What is the cause of these surface artifacts?

3D printing isn't plug-and-play. A different material color, different brand, different moisture level ... or just a different spool sometimes. It will do you good to play with the retraction settings and learn what those settings are for.

Re: What is the cause of these surface artifacts?

What printer are you running?

You need to look at your retraction settings. Retraction, retraction speed, extra restart (might need to add a little negative there) and coast will all impact extra material that the perimeter start point.

Re: Upgraded to a Duet 2 Controller

Working on my N2+ now - here's a shot of the board mounted using the brackets I shared above. I replaced the blower with a 24V unit, and also removed the standoffs in the case which space the blower away from the back of the box. On my N2+ (cover screws on the box) there were inserts in holes that s...

A brief follow up on my experience with an N2 running with the Duet2 Wifi board. Real happy with the outcome. The touch screen is not in used.
