The differential gears are nothing to do with prime but to add the traverse into the equation and also to add a rotation for a helical. I have a diagram of one at http://www.collection.archivist.info/hobbing.html then you can wind the hob back along its cut traverse and it remains "in gear" Dave

I have looked at some gearing diagrams of gear hobbers and I noticed that a 'differential' gear set was included. What does that actually do? I suspect it is for cutting prime number gears? - Original Message - From: emc-users-requ...@lists.sourceforge.net To:

I thought it would be a good idea to display what the RPM setting is before the spindle is started. I see current_rps is right there WHILE the spindle is running. But when I enter "S1", it's set inside LinuxCNC even before M3. I'd like to display it in pyvcp before M3 uses it. current_rps
