    Re: Yet another epoxy granite mill

    Got the controlpanel wired up:
    503516 503518

    ...now i just need the mounting arm for it...and attach the backplate :-)

    ...on to the next part: finish wiring the main electronic enclosure!

    No, not yet :-( But i have moved it around many times since it arrived because it is always in the way of something ;-) But hopefully VERY soon as the electronics is almost done and i'd like to test...

    I'm sorry to "hijack" your thread here, but I'm curious if you have any pictures of the setup doing this? I'm about to do the same with my EG mix to compare and i'd like the tests to be somwhat...

  8. Re: Epoxy-Granite machine bases (was Polymer concrete frame?)

    I haven't done much research into EG vs. UHPC, it mostly seems like a "religious war" and in my opinion there is not a clear "winner". The biggest downside to UHPC (as far as i've research!) is that...
  9. Re: Epoxy-Granite machine bases (was Polymer concrete frame?)

    Yes and no:-) I didn't get the institute to do the testing. Mostly because the ones i talked to usually "just" test concrete and their main focus is compressive testing, which isn't very usefull for...

    Re: Yet another epoxy granite mill

    As part of getting the electronics in order, i'm trying to figure out how i'd like the control interface....and honestly...i have no clue :-)

    A little progress on the electrical part of the project:
    501228
    ...might look a bit messy without the covers on, but looks very tidy when they are mounted:-)

    The panel is like 95% done. I'm...
  13. Re: Advice needed for parts selection for new DIY CNC Mill

    I'm guessing your simulations assume "100% rigid connections" between all plates? That would require full penetration during welding, which (i think) would be impossible based on the images you've...

    The pump is an "air to hydraulic pump" from https://www.amf.de/en/ with article no. 6904-25, you'll also need a valve to release it, i chose 6904-52. Finally you need a cylinder that matches the...

    Re: Yet another epoxy granite mill

    I think i got room for everything for now:

    ...there is still room for 4th and 5th axis drivers next to the line-filters...i hope :-)

    Small update: Got the electrical cabinet mounted tonight:

  20. Re: Advice needed for parts selection for new DIY CNC Mill

    I'm honored, but not sure i can live up to these expectations :-) My take on this is that "everything moves and everything is rubber". So, i wouldn't trust a steel-plate to hold pre-machined inserts...
  21. Re: Advice needed for parts selection for new DIY CNC Mill

    With cost in mind i would just let them mill the flat surfaces, it is where you get the best "value" as i see it AND is not easy for you to do it yourself with decent results. The other stuff you can...

    Re: Ballscrew Locknut tension - fixed end mount

    Ok, cool, so the consensus is that matched bearings should just be "nice and tight" and no need for the torque-wrench on this one...
