Re: How to keep corners good when printing fast?

Coming back to this topic with some additional experience, I'd also suggest running an extrusion width about 1.2 x of the nozzle diameter. The plastic expands naturally when it exits the nozzle. Trying to maintain an extrusion width equal to the nozzle diameter requires the stream to be stretched a ...

Sensing an X/Y Shift

At the day job we have a MarkForged MKII printer. I just discovered an interesting feature of this machine. Between layers the head makes a trip to the X/Y Home. I had wondered why it did that. Today I found out. Some support came loose from the bed on the build I was running this morning. I got a n...

Re: 100% Infill Problem

I use 9999 bottom layers when I want a solid part. I find it works better than infill.

Re: First Layer Issues

your build plate is too far from the nozzle. Decrease the starting Z height - you can do that with the G-Code Z offset in S3d, but there should be a hardware adjustment on your printer as well.

Re: Too Heavy 3D printed RC Airplane- Dremel Idea Builder 3D40

Is the part building correctly? It appears to have internal ribs in the image with the weight spec, but yours looks to be built solid with top and bottom layers, perhaps filled with infill. S3D will give you a weight estimate when you PREPARE TO PRINT. What happens if you set the print up with ZERO ...

Re: S3D Misses The Mark On Weight And Time Esimates By A Lot!

I ran some parts last night on my Raise 3D N2+ with an aftermarket Bondtech extruder. Looking up ABS density it ranges from 1.06-1.08 g/cc. If I enter the density as 1.07 the predicted weight for the print is 314.8. With a density of 1.08 the predicted weight for the print is 317.7 Measured weight i...

Re: Make a part of a print solid , but not all

One thing I did was to "drill" some very small holes through the area that I wanted filled in. I don't recall the size, but maybe .004". Going too small caused issues with the STL file. S3D then drew perimeters around all the little holes, so by matching the hole spacing to the total perimeter X2 I ...

Re: Calibrarion axis steps x y z DREMEL 3D45

If you are wanting to dial in dimensions on your machine to get more accurate parts, I have a procedure I've used very successfully. You can find it in this thread. Note that there are newer files posted in the last post. https://forum.simplify3d.com/viewtopic.php?f=9&t=6130&p=26646 If you are needi...

I've generally had to try a few tools when repairing a big file. I haven't found one tool that works great on everything.

Re: S3D Misses The Mark On Weight And Time Esimates By A Lot!

Make sure the DENSITY of the filament you are using is set correctly. When I've checked part weight predictions they've been spot on. That calculation is a cake walk compared to print time.
