Rhino Challange Question

It slows down for cooling if you tell it to slow down for cooling. Check the Cooling tab.

So if the option is checked that says "adjust printing speed for layers below 15 sec", it will slow down the print speed only if it takes the current layer less than 15 seconds to complete right? Even with the single unit a layer would have taken longer than 15 seconds to complete.

[jimc]

there is no way that a pair of those took more than 15 sec. perhaps the first few layers for the flange but not the other layers. a single small piece like that by default will always take longer to print that multiples. set the preview to print speed and slice one then set a table of them up and slice it and preview again. you will see a color change showing the speed difference.

I suppose once it got off the end disks and started doing the axle then yeah, that part goes very fast and shows up blue in the preview. I think the disks with 100% infill take 15sec or more to do, but I didn't time it so I don't know for sure. I always wondered why narrow tubes printed slower, I always figured tighter curve radius had to print slower or something but now I guess it's because the layers complete so fast that more cooling time is needed. I've never paid much attention to the cooling settings, I've always used the defaults.

So it really does print twice as fast doing a whole plate full... that's pretty neat!
