[Emc-users] another (possibly silly) EDM question

For you EDM experts out there: How well would it work to do sinker EDM with a 3D printed metal part? In other words, have a part printed to "near net shape", and use a machined (graphite or copper) electrode and EDM to take off just enough material to get it to the final shape with a smoother

Re: [Emc-users] OT: Need some guidance on high temp/pressure water circuit

How about using self-closing quick release connectors? They're used in hydraulic piping, especially on things like farm and construction equipment with attachments that are swapped often. The amount of fluid loss with each disconnect would be small. Wear nitrile gloves and use lint free cloths

Re: [Emc-users] M. P. Jones has deal on manual pulse generator

That is about the going price on ebay (between $15 and $20..) we have used a bunch in our projects. No issues so far. sam On 2/13/2017 10:35 AM, Jon Elson wrote: > M. P. Jones has some 80 mm manual encoders for $19.95. 100 > pulse/rev, differential output, they don't say anything > about

Hello, you can look at http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Parallel_Port_Tester There is a version in the first linuxcnc screen (aka the config picker) If you use any of these, check the address and if different, make copies and edit These configs set the port simply as type 'output', but

[Emc-users] M. P. Jones has deal on manual pulse generator

M. P. Jones has some 80 mm manual encoders for $19.95. 100 pulse/rev, differential output, they don't say anything about detents, but hopefully it has them. Part # is 33106MI Jon -- Check out the vibrant tech

Re: [Emc-users] how to test output pins?

Thanks Todd, which parallel port test program should I use to toggle the output pins ? Thanks, Valerio On Sat, 2017-02-11 at 09:43 -0500, Todd Zuercher wrote: > Most parallel port plugs have the pins numbered, and the Linuxcnc parport > driver's hal pin numbers correspond to that numbering.
