Hi All:

  Version 3.0 is online, and a video to show any changes since the spring. Any bugs I have discussed as
being fixed , this version should correct as well.

Have fun, welcome back from summer..

I installed 3.0 and randomly dinked around a bit.  Cage gear simulation with 4 circle1 spokes is somewhat weird.  The spokes in the wheel jump around quite a bit, and if the wheel and pinion both have an even number of spokes the teeth don't mesh.

I haven't looked at the video yet, which is  undoubtedly why I couldn't get florishes to work.

The copyright date is still 2013, but they tell me I'm behind the times.

Looking forwards to another season of amazing things!

I should add that this is W10 64b, latest insider preview, on an i5-5200u laptop with the latest intel drivers for the chip's build-in graphics.

Hi Kirk:

  Drop a project file here for me will you if you get a chance, Ill see why the jumping...

No project, I was just using simulation on the Tools tab.

I've attached a screenshot.  Looks like I have rhythmic geneva checked, but no geneva.  Hmm...

Kirk

Hi Kirk:

  My fault, I should remove at least one tooth in a rythmic geneva. It faisl if it has all its teeth
as it isnt rythmic anymore. Click on any tooth on the pinion to remove it and the sim will work
properly..

I hadn't really intended to make a rhythmic geneva, but since I was just playing around trying random stuff...

Clicking on a tooth removes all the other teeth, but in the simulation the tooth meshes into the center of the pin, rather than the space between them.  Both the cage creation screen, and the project screen, have the same issue.

I have a new 3D printer coming, a Thingybot Delta.  Perhaps a rhythmic geneva would be a good test.  Never made one before.  Wonder if the pins show up in the stl?  Update:  Yep, you select all of them and combine into a single object.  Cool, gives the choice of cutting a lot of pins from a different material or printing the whole thing in one shot.  Maybe I'll unjam the extruder in the Printrbot (lesson, chuck the cheap cr*ppy filament in the trash and order up good stuff) and see what happens.

Kirk

Looks like the escapement simulations work now!  Thanks!

Sweet features added!  Need to find some time to play with it.  You know, the day job sure gets in the way of my hobbies.

I drilled the baked in crud from the now discarded mystery brand cheap filament and resurrected the Printrbot, and made a two tooth rhythmic geneva.  The pinion turned out fine.  I selected all the pins and the cage wheel and created a combined stl object.  No joy, all but one of the pin locations were created as holes, then the upper half of the pins dropped on the holes with no overlap - they were the same diameter as the holes.  Just noticed when removing it that one pin was part of the wheel, but only one.  Printed it for grins, anyway.  Have a new spool of HH3DP gray to replace the mystery brand "silver", so this was a fair test of it.  Good stuff.

In a perfect printer world the pins would have dropped into the holes, but they did print on top, with essentially no overlap, some of the plastic from part of the pin dropped into the hole and left a gap, and the pins wiggled a bit as the top surface was printed.  Everything was sized properly, the pinion fit into the wheel when carefully tested, but any load will shear off the pins.  Pic attached.

I expected the pins would have started at the base of the wheel and become one with it, then projected out of the top, as if the separate objects were merged before the stl was created.

Kirk

Art,

Great job...you are amazing....

Okay........would it be possible to turn a "flourish" into a spoke?

We could create some very fancy wheels like that...........

Your opinion,

Richard
