Binky's First Smoothieboard print

[lordbinky]

So here's my first print, a heatwave julia vase ( 1.6x increase in size, .2mm layers). I haven't seen a Moiré pattern in the horizontal layers before so I was surprised by that. Only one small bit of layer separation, which bodes well for me since I plan to do an enclose soon. I'm really happy my mods and tear/down rebuild finally got me to satisfactory prints again. I'll have some more things to post Sunday (I hope), it depends on whether or not I get that day off. Anyways, I'll post more about the smoothie settings then as well.

Cripes that looks nice! As for the moire pattern, are you talking about the bottom of the print? I had to look up 'moire' to know what you meant.

I also like the Marvin the Martian lamp. I'm also quite jealous of the huge digital calliper...

looks pretty sweet so far! The Smoothieboard seems like a nice upgrade!

A very handsome vase!

The circle patterns in the base are indeed what I'm referring too, and they visable in person not just seen when you take a picture and shrink it. I didn't know the term moire either until I did image processing work. Before that it was just 'the weird shapes when you resize a pattern'. Also the towers are using 0.9° steppers (the extruder is still 1.8°), so that helps the smoothieboard show its stuff. I think it really shows how great of a printer the Rostock Max is when the limiting factor is really the electronics moving the physical parts around and not limitations in the physical build itself (although it comes at the cost of being less forgiving in it's construction).

I am begining to wonder if this pattern is from the steppers, or perhaps from the belts themselves?

I may try a spectra line setup on my minikossel as an experiment.

It's a secret NSA digital algorithm to track the parts you make. Just in case you ever start manufacturing guns once they outlaw them here in the states.

If you're getting miore patterns, (and not just vertical banding) there's lots I could do to change the pattern like change the base frequency, the pause between steps (settling time), segments per second,etc. Some of those settings could get rid of the patterns for certain prints (and cause them in others that didn't have them before), .

If I'm thinking about this right, it's a product of translating the x/y points from a higher density coordinates to the (relatively) smaller density coordinates physically possible by your printer. The patterns occur because you have consistency in this translation (which says good things about the build) and that the coordinates are fairly discrete, so unless the spectra lines smooth movement (and reduce positional accuracy slightly) it wouldn't get rid of the pattern. When you think smoothing in this context, think of how jagged aliased lines disapear if you blur an image.
