1  General Category / Newest Rev Release / Re: Version 2.279 online on: February 16, 2015, 02:34:55 AM
2.279 (and the previous version) is cactus on my PC.

When I start, the window strobes between the blue check pattern an black - I thought it was while "tip window" was up, but it seems timed - it does it at other times for about 1sec. 
The message text at the top center is overwriti ng itself (see attached)
When I try to create a gear using the "Circular Gear Module" the display is black.
I can load an existing project, which again shows a black screen.  I can click on the screen and get the check pattern.  If I use the middle mouse button, I can then view things.
When I simulate it, nothing simulates .  The 3 circle orientati on indicator flashes.  If I hold down the middle mouse button the gears simulate properly.

Thanks.

My issue wasn't that I needed extra strength with a wider face, it is those little peaks, which don't 3D print well.  I originall y was going to edit the .stl files and try and stretch them, but it was easier just to slice at the round face.  So I needed to add some width back.

Can the face width of a bevel (helical) gear be set? 

There is a field for it, and it is displayed in the list of parameter s when a gear is placed, but the actual gear doesn't change.

Picture attached in case my terminolo gy is incorrect .

I accidenta lly pasted a URL into the "Module" field in the Spur Gear section in GM and it locked up.

I tried to copy the value from the Module text box in GT using Ctrl-C, but Ctrl-C copy doesn't work.  Mouse right click does.

It appears to lock up GM if any non-numeric text is entered.

1) Hypocyclo idics
2) Casing/Boxing.
3) Non-Circular Gears.

From a sales/marketing point of view, Hypocyclo idics come up a lot at cnczone in discussio ns about DIY 4th axis and other low backlash gearbox situation s.

I'm seeing a few glitches in the stl files generated for bevel gears.

I'm only using simple software that doesn't seem to be able to repair them properly.

When I load a bevel gear into Netfabb Studio Basic 4.9 (the free version), it shows a strange line through the gear, see attachmen t.  Even after repairing in NetFabb, the line still appears.

I've ignored this up to now, but it has caused some applicati ons to crash and produce funny results.

Closer inspectio n in Blender shows what looks like overlappi ng triangles, see attachmen t. 

It doesn't appear to be a completel y duplicate d triangle - if I delete one of the overlaps, it reveals a hole through the object, see attachmen t.

This was done using a straight bevel, mod 1, PA 20, 14 teeth, 4mm hole, 5mm face.

What I ended up doing was calculati ng the distance using the Outside Diameter, Face Cone Angle and Cone Distance.  See picture below.  I'm not sure if Cone Distance is the correct value to use, but by eye the results look ok.

A bit of a brain fade there.  Cone Distance isn't used.  It's just...

L = OD/2 * tan( Face Cone Angle )

Thanks for making a new release for me, unfortuna tely I struggled to find the reference point to use.

What I ended up doing was calculati ng the distance using the Outside Diameter, Face Cone Angle and Cone Distance.  See picture below.  I'm not sure if Cone Distance is the correct value to use, but by eye the results look ok.

Using the outside corner made it easy to define a reference plane using my CAD software.

I look forward to the future release where we can just use the distance from the axis intersect ion to one of the gear's front or back faces.

Thanks,
Frank

Thanks for the reply, but that didn't help.

I did what you suggested, and this is what I got, see attachmen t.

The red cross is approxima tely 0,0,0

It doesn't help me position the gear on the axle at the correct position to mesh with the other gear. 

I'm trying to position 3 gears on a tee shaped bar as shown in the picture.  I need to know the positioni ng of the gear on each shaft just as I would use the center distance of the spur gears to place them

I clicked on the AutoTrain button, and it said it needed to do some calculati ons and would be back in a minute.  I just got an error box saying...

c:\Program Files\Gearotic Motion Release\gprimes3.bin was not found.

The Gear Train Calculato r then never shows any gear combinati ons.

Turns out it was a permissio ns problem.  GT tries to write to "c:\Program Files\Gearotic Motion Release\" but can't.  I need to run it as administr ator

How are the dimension s defined for a bevel gear pair?  I have a pair of Mod 1, 20 deg, 28 tooth gears at 90 degrees. 

GM says the gear center is 28.0.  When I put the models of the gears into my CAD program and try to align them by eye, the back of the gear is about 15.0 away from where the axis meet.  What is the position on the shaft, and from where to where do I measure it?

When I create the gear, I ask for a face width of 5.  The Gear Thickness on the project display shows 4.2426.  Is face width supposed to be the thickness of the gear?

Thanks,
Frank

I downloade d the latest version today - I think it's the latest version - there's no version number in the about box.

Just a couple of minor issues...

* When typing in the edit boxes when a gear is selected, hitting the "DEL" key to delete a character prompts with a dialog to delete the gear.
* The first thing I did when I installed GT for the first time was to checkout the new GT2-2mm pulleys.  I didn't quite get what I was expecting - see attachmen t.  This went away when I switch the Units from inches to mm in the Global settings.

Which printer are you getting?
15  General Category / Newest Rev Release / Re: Sample HiRes STL output file on: March 27, 2013, 12:48:04 AM
Slic3r liked it although I had to flip it in an external program.  No warnings.

This took 2 hours to print.  Scaled to 50%.  Those peaks are a bit of a mess.  Now I just need an extruder that dispenses white chocolate!
