I'm trying to relate a simulatiion to a real life situation but am having problems.

Whichever parameter I change (drop lock angles etc) the pendulum swing stays at +/- 1.5 deg.

When I simulate the rotational angle changes from about -4.4 to about 1.4, again not changing with a change of parameters ...

Hi Art

Have upgraded and have used the workbench to produce the gcode and simulated it - no sign of the jumps.

Many thanks

Hi Art

Attached is the project file after creating the toolpath. On reloading I can't see the toolpath.

The steps I take are:

start gearotic 2
open Planetary.gth
click Output Options/CNC
click Project Tree/Shaft/Planetary--Driver
click Gen Paths

Artifacts should now be visible. there are three ...

Hi Art

Thanks for taking the time to look into this.

My code is attached, note that my zero is in the centre.

Hi Art

I've loaded the file I posted here and re-generated the G-Code from that.

The tap file has the same numbers as reported earlier eg

X 1.6293 Y -9.1360 Z -1.0000
X 1.6430 Y -9.1325 Z -1.0000
X 1.7666 Y -9.1035 Z -1.0000
X 1.8810 Y -9.5902 Z -1.0000
X 1.7666 Y -9.1035 Z -1.0000
X 1.8901 ...

Project file attached (hopefully).

Hi

I am trying to design a planetary (inside) gear and GCode output as follows:

Circular Gear Module
Round Gear (Planetary)
Spur
Module 1.0286
Pressure Angle 20
Tooth Count 21
Involute

GCode Processing
2.5D Profiling
Tool Dia 1mm
2.5D Depth 2.8mm
Depth per pass 1
Spindle Speed 7000
Feedrate 1

Hi

The shaft distance calculator doesn't seem to work for planetary gears.

For one planetary and one pinion the shaft distance should be the difference between the pitch radii rather than the sum of the radii.
