Re: Printing time significantly different than build statist

Pulling the acceleration values from the machine can be problematic because different firmware packages calculate acceleration and jerk settings differently. This can have a pretty big effect on time estimates. Simplify could get burned by calculating acceleration differently than your machine (and ...

Re: Printing time significantly different than build statist

We all have this problem to varying degrees and yes it's mostly related to acceleration for each individual printer. Simply cranking up the acceleration may seem like a good idea but it does come with possible print quality issues. Corners can get messed up, any start-stop point may get messy, and w...

Re: Variable height layers

Yes, I think this is a duplicate request. I think the best way to calculate and implement variable layers is based on part angles. The user would specify the vertical layer height and the minimum layer height that would be implemented near horizontal. This could smoothly vary in .01mm increments. A ...

Re: Preview Mode Missing Critical Information

I think these are good ideas. The current layer height in preview would be extremely useful when setting multiple processes. Starting and stopping processes properly can be problematic currently because the setting in the process is in mm and not layers. In order to calculate the correct start/stop ...

Re: First Layer Width doesn't seem to do what I think it sho

I think what people think the first layer width setting "should" do and what most of us want to use it for are two different things. The setting increases the width of the material coming from the nozzle but also increases the distance between paths. This means that there is little change in the amo...

Re: Outer layer rectilinear fill angles

Unfortunately, you can't. I would also like to see a concentric option.

The start angle is already a feature request. I hadn't thought about the end angle...

But, the workaround is to rotate the part (hint, the first angle used for the bottom layer is 45 degrees)

Re: Solid layers on top of infill are all messed up

If you don't want to increase the infill for the entire part you'll need to run 2 processes. The first process is most of the part and has the low density infill. The second process is just the top maybe 5mm of the part and has the dense infill to support the top layers. You just have to punch in th...

Re: Dynamic layer thickness

Here's what I'm thinking Assumptions: Use the same angle measurement method already implemented for supports. The layer change would be non-linear (angle changes near vertical have major effect while changes near horizontal have a minimal effect) Layer thickness would be based on the most horizontal...

Re: Complex infill managment needed for large prints!

I'm thinking about a variable infill that doesn't just support the top of the model. Think of it like a cake with two layers of frosting on the outside. The outer layer is the number of perimeters. The next layer inside is the dense infill (for strength and top support). This would have a thickness ...

Re: Add a new printer.

The fastest way I've found to switch between printers is to have a factory file for each one. Pulling up the factory file will change to the new printer without having to page through a list. Just save a factory file with a small part in it for each printer. Pull up the factory file and delete the s...
