Re: [Emc-users] Spanning beam lathe stand

You would NEVER bolt a machine to a building. If you are worried about flex, You might double up the column and connect that to the base. You might add 50pounds of steel but you'd still not bolt that to a building Has anyone been able to measure column flex. Possibly with a nail indicator.

It ought to be worth close $1500 just for scrap metal. (probably weighs almost to 15000lbs) Still a shame to see good old iron like that left to rot outside. - Original Message - From: "dave" To: "Enhanced Machine Controller (EMC)"

Thanks Jon, After having used steppers for so long seeing one of the .nc sample files move the servo in such a silky smooth motion is really sweet. I did manage to get everything working and not only timed a 120ipm jog but the pulley actually turned the correct distance too. I'm guessing the

Re: [Emc-users] MachineKit on the BeagleBone Black

Thanks for the reply Andy, The Machine Kit forums give the impression that for any LinuxCNC type questions these forums are the place to ask and only Machine Kit specifics are addressed on those forums. All very confusing. I was hoping there were people on this forum who had experience with

Re: [Emc-users] Spanning beam lathe stand

If you look at semiconductor fabs where that make parts with features sizes as small as 10 nM now they seem to never bolt equipment to the floor. No matter how strong your machine is, bolts will distort the frame. They take strong measures to isolate the machines from the building. Of course

[Emc-users] MachineKit on the BeagleBone Black

I've resurrected a nine year old project and am finally adding CNC to my G3616 mill. Way back I bought DC Servos, HP_UHU controllers, pulleys, belts, angular contact bearings but everything languished in a box after the pattern for the HP_UHU heatsink was a failure so I never got past getting the

Re: [Emc-users] Spanning beam lathe stand

Rather a cute idea. :-) So taking it a step further ... use a double column of CMU for the headstock and a single column to support the tailstock. Epoxy the CMU to make a good column but don't epoxy to the floor. Use a rod end or automotive ball and socket to relieve stress on the
