Spoke Problem and Geneva

[John T]

Hi Art,
I'm have a couple of issues:
1.  When applying Damper spokes to a spur gear the gCode is not as shown on the Project Screen.  The gCode is cutting through one of the spokes (6 O'clock position).  See photos.
2.  Second thing is when I'm generating a Geneva gear and try to change the module to get the size I want it won't go on to the project screen saying they are different modules.  If I leave everything from the initial default I can get them to go on the project screen, and generate gCode.  So the issues is that I can't seem to change the size of the geneva gearing.

Hope you can help.

Hi John:

  Ill do a change this week to the module checking o geneva's, Ill let you know when its ready, I dont think
relaxing the module check would be a terrible thing..Youll just have to be carefull that things actually mesh.

  Your spokes and such ( Ive seen a few problems there lately for some reason ), I'll have to check out more deeply.
I know its a rounding error of some sort..never seems to happen in metric.. Ill investigate that at the same time.
It will be a few days, Im working on the new 3d bevels and its a confusing bit so I cant leave it yet, but it shouldnt take
more than a few days to complete and Ill redo the tolerances of the GCode section.

Do me a favour, save the project with that badly spoked damper gear, and post that project file here as well as your setting
for the tool size and point distance setting so I can duplicate what your getting, it should allow me to more quickly zero in
on whats causing the error. I suspect the spokes hit a trigger point with certain radius of tool where the allowance of  tool move
approaches zero and causes the cut off. Ill be a slightly smaller tool radius stops the weird output. Dampers are bad that way as the
bend in the spokes can be hard for the tool to reach..(but shoudlnt cause an error like that, it should instead simply cause the output
to be sligthly malformed in extreme curves..)

Thx

Hi Art:
Here's the info.

I've included two files one with just the bad spoke and a second one where I started with two spokes - no problem then three etc until the problem started at 5 Spokes. 
I have Gearotic installed on two computers and when checking I discovered that the problem didn't exist on the second computer.  The only variable that I noticed was the Gear Point Distance.  At 0.01 inches the problem exists (for five spokes) while at 0.05 the spokes appear correctly on Mach 3.  So it appears that its something to do with the Gear Point Distance.

Anyway the first attachment is just one gear with damper spokes that fail at Gear Point 0.01 (using Version 4.87)  The tool size is 0.0625

If these problems don't exist in metric then maybe I should switch?  Not a big problem for me.

Thx John:

  Ill check it out this week. Usuall a lower point distance is better, the higher one working may mean the points are too close together. Metric usually works better in all things I find, inches just amek too many small numbers. That having been said, both should work.. Ill let you know what I find.

Thx
