Who sells ELS components or completed assemblies? |
| JohnHaine:
If you are going to do this why not just fit full cnc? To do tapers and threads with the ELS you need steppers on the leadscrew and crossfeed anyway. In my experience I don't do much lathe threading but loads of other stuff which involves turning handwheel and getting bored, why not have a machine do it? But as JS says, Mach 3 isn't wonderful at threading with a single pulse per rev sensor, better to use Linux CNC so I'm told, I'm going to give it a whirl. |

Turning down a piece of stock is just the same as turning a very fine thread. You don't need to start up a computer to run it, it's all built in! Regards, Matthew |

just had a random thought regarding the single line encoder issue with both MACH and ELS. seems that both systems are unable to work with anything more then one pulse per revolution of the headstock. but why cant you simply use a 4 slot encoder and multiply your screw pitch by 4? e.g. 1 tpi required, would be inputted as a 4 tpi. thus for each 1/4 of work piece rotation the tool would advance by 1/4 of an inch and a whole rotation would equal 1 inch ? seem too simple an answer to me, must have been tried already? I imagine there must be a limit to how fast the control can receive signals and computate the required movement, but surely at thread cutting speeds that's not much of an issue? |
