[Emc-users] Question for people using new qtpyvcp gui and touch screens

2020-02-22 Thread andrew beck
Hey guys. Just thought I would ask here hoping to get one of the qtpyvcp guys so comment and let me know what they think. I can get some Elo Touch screens from old kiosks. They are industrial and very nice touch screens built for public use. Now I can get them pretty cheap and Elo makes Linux

So your machine can access any point along a specific diameter cylinder? I'm curious about what the machine does. But the kinematics could be literally trivial. How to do this depends on what you want your g-code to look like. You can always write the g-code using native machine coordinates

I have 8i20's right now. I would use STMBL but I've already spent the money on the 8i20's. I'm willing to do some coding. I implemented halports in linuxcnc and intended to extend that into hostmot2. Possibly for UARTS and I also need to create an interface with datapainter so I can move my laser

hi Nicklas: I think you keep the X as linear and do a Cartesian to polar conversion for the Y. This is sometimes done to get a really stiff Y axis. Years ago I saw a utube of a shop doing one with a decently large rotary table; as in 18" or more. Dave On 2/22/20 12:50 AM, Nicklas Karlsson

Rene thanks, This will help a lot. I'll study that implementation. I would like to get my 5i25 to be able to process the encoder data. Is the protocol direction only one direction from the encoder? If it were I could just hook up the read signals in the 7i74 and create a vhdl component that

It's not directly relevant, but there's a Linuxcnc compatible PCI card for Yaskawa Mechatrolink protocol http://yurtaev.com/ymtl2p.html I mean, Mechatrolink drives can be cheap sometimes. сб, 22 лют. 2020, 17:04 користувач Curtis Dutton пише: > I'm trying to run some Yaskawa Sigma V motors with

I'm trying to run some Yaskawa Sigma V motors with a 5i25, 7i74 and 8i20. I want to read the encoder of the motor with hostmot2 SSI. I have all of my firmware set up, but I just cannot find the encoder protocol out in the wild. Does anyone know it? Also I would like to start a wiki page that

Did not find list of kinematics module but. Do not think this kind of kinematics module exist, scara however come close and so could be a good starting point. > > No attached drawing. > > Trying to attach smaller version of drawing: > > > > If it doesn’t work, see here: >
