Welcome to the SeeMeCNC Community

I found this object and thought it would make a nice test print. This was only the 4th item I've printed and I'm really happy with it. There are issues, but it stayed on the bed and the issues are nothing major.

Can you pro's take a look and point out what you see wrong and possibly what actions should I tweek to make it better? This is so damn addicting!!

Thanks

For being one of the first prints, that looks great! Even the retraction looks like it's doing a good job. Are you printing in PLA or ABS?

Looks pretty good. Nice, consistent layers, minimal spider web, perimeters and top fill seem to be bonding well.

If you're using Slic3r you might want to tweak up the % extrusion rate on the outer perimeters and top/bottom layer a little bit just to smoosh that shell a little more. You might also benefit from increasing your retraction rate by 30-50% to get rid of the whiskers.

Might.

I'd be pretty happy if that came off my printer exactly the way it is.

+1 I would add that once you get those settings tweaked look at lowering your layer height a little at a time. It will go miles in improving surface finish.

Thanks so much for the feedback. I'll try those tweeks and see what happens. I would not mind making another one (or three) of these things.

This was printed in ABS & using Slic3r with the default 225 / 90 heat settings.

One of the dual extruders printing one of these with a different fill would make this look really awesome! Though you'd need to get it to put numbers on the fields....

Bloody D&D nerds

You're just mad because all your saving throws have failed.

Is a dual extruder available with the Rostock? I'll have to search around for that option. That would be fun to get down the road. But what did you mean with the "numbers on the field" comment.


I thought this detail was interesting. While printing the top layers there is a point at which the extruder has to draw a line across mid air from "tower to tower". Some of those strands did not attach properly, basically because it didn't draw the line far enough over the distant post. Why not overshoot to ensure the line attaches properly? I guess this has to do with how the Slic3r converts the object into action steps for the printer, right? If so, would a different slicer be better at this "over the air" type of object?

oh. okay.. lol

So I tried some of the adjustments you guys mentioned, listed below. Then I printed a test of this plaque (80mmx40mm)..

https://skfb.ly/zTJA Slic3r v1.0.1
.3mm Layer Height
.5mm 1st Layer
Brim = 5 (I just wanted to see what this would do)
Advanced: Extrusion Widths
.....Default ext width = 120%, Perimeters 120%, infill 0, solid infill 0, Top Solid infill 200%

For my purposes this turned out nice. But I see that it's really rough around the edges. I might make the letters thicker next time. Any other suggestions?

.25 layer, .35 first layer height.

Thanks Gene. I'll give it a try
