    High quality hand wheel? Buttons?

    Hi,

    I'm designing a new controlpanel for my CNC mill and i'd like to use some good components and not just the cheapest of ebay. Are there any recommendations for e.g a handwheel in high quality with proper haptic feedback etc?

    What about buttons? I''ve considered using custom membranes because it would look nice and there are good options, but i don't know if its better with a "real button" in the day to day use. I think i'd prefer real buttons, but what are your opinions on this and are there any recommendations here aswell?

    Thanks!

    /Thomas

    For encoder hand wheels these are really quite good, with reasonable feedback.

    As far as push buttons and switches, real ones are the best. I normally buy from Automation Direct. https://www.automationdirect.com/adc...-z-_indicators They have consistently high quality industrial grade products. I would avoid membrane switches for day to day use.

    I also like to minimize the number of physical switches and push buttons, but rather have on-screen switches for all functions except the E-stop, reset, and power on buttons. On-screen buttons can be operated by touch screen or a mouse click. My preference is a mouse click, I really don't like touch screens.

    Handwheels are generally simple ~100p/rev incremental encoders. You require one to match your input, generally they are 5v RS485 output standard.
    I always used the Telemecanique style PB's, They don't make the model any more, but I see they are cloned now from China and much cheaper!

    Thanks for the suggestions and links! I'll look into that... I'm also going for minimum amount of buttons, however, some things (besides e-stop) need to be physical IMO. Like feed overrides, start/stop etc...

    Regarding the membrane-stuff, i have the same feeling that for a "once in a while" they are ok... but working continuesly with them would be annoying... Do anyone know what type the Heidenhain use? e.g. https://www.fdz-shop.de/user_html/14.../g/3030116.jpg I've never seen a Heidenhain in real life, but it looks like some sort of silicone keypad, i wonder if they can be customized like membranes?

    Yeah, i'm going to connect it to a Beckhoff ethercat module to connect to LinuxCNC via EtherCAT, so i'll choose the correct module when i know the encoders requirements:-)

    Regarding the chinese clones: I actually used a couple of chinese clones in a previous project, but i ran into problems with the e-stops. I had a bunch in series and the contactor resistance was almost 10x higher than on a proper "Telemecaniques"-original. Also the vibrations in the machine made the resistance fluctuate like crazy....So it worked with one or two in series, but with 4-5 it started tripping the e-stop randomly... The solution was to buy replacement contacts for the e-stops from Scheider(i think they bought Telemecanique?) and all problems went away...just a tip :-)
