Some progress here. I continued making the base and found out that the profiles with t-slot are slightly larger. Since they fit one to the other and there are 10 of them, this error will not allow to assemble everything.

So I had to fix it.

Finished all the profiles and parts for the base.

Now for the fun part. I've been wanting to try using profile filler for a long time and now I've finally made up my mind. I decided to use epoxy granite, it's easy to make and adds quite a bit of stiffness and most importantly, dampens vibrations very well. I made some samples to check the composition of the mix, everything went well with the calculation.

Then I decided that it would be easy to put the tabs in the profile with an internal cross-section of 70*30mm. But it turned out to be very difficult, don't do it like that.

Laying the mixture inside and tamping it down through all those tabs wasn't easy either. Now while the epoxy granite is gaining its strength I can do the other parts.

You are likely already aware of this, one issue is that some fillets are extending below the work plane:

My first intuition would make me think that this happens because the vertical line segment is too short to be trimmed back far enough to fit a fillet with the requested G64 Px Qx properties. In this case I would expect the optimizer to either
not cut the segment at all and not create a fillet
or (a more sophisticated path)
cut the segment the way it does now (ie to the minimum length) and create a fillet with adjusted parameters so it does not extend beyond the original segments.

int optimizer::trimCurve(emcmot_segment& seg, int& trim_front, int& trim_back) {
    double trim_distance = G64P; /*seg.tag.fields_float[3];*/  // G64 P..

    // Trim conditions.
    if(trim_distance<=0){
        std::cout<<"no trim distance for segment id:"<<seg.id<<std::endl;
        return 0;
    }

    if (trim_distance >= seg.length / 2.0) {
        trim_distance = (seg.length / 2.0)-1e-3;
    }

    if(trim_distance<=1e-6){
        std::cout<<"too short to trim, no trim is done for segment id:"<<seg.id<<std::endl;
        return 0;
    }

    if(seg.canon_motion_type==1 || seg.canon_motion_type==2){
        trimLine(seg,trim_distance,trim_front,trim_back,false);
    }
    if(seg.canon_motion_type==3){
        trimCircle(seg,trim_distance,trim_front,trim_back,false);
    }

    return 0;
}

Power on the PC, press F2 when logo shows, in the BIOS find the parallel port (probably in peripherals or similar), check if the parallel port address is 378 or 0x378

Hi I was able to take a picture showing all the details on the BOB. the loose wires you see wer connected to the limit switches on the mill. I marked them and disconnected them all, because I thought maybe they were the problem but no dice.

There is no "make install" for RIP, after setuid you just set the 'run in place' environment and start linuxcnc, see attached.

Dear fellow members
I encountered a problem while installing and compiling Linuxcnc from the source code. ./ configure and make can proceed smoothly, but there was an error with make install: there are no rules to create the target‘ install kernel dep’, which was stopped by the ’install software‘ requirement.
how can i slove it.

I posted this on the wrong topic last night, fixing that now

Santa came early this year, also brought a Zoyi ZT-703S osciloscope!

By now i got it working so the video is on the way...

After reading this several time i still can not figure out what you are asking! I am sure you are not asking for wiring as you can do that easily, so...
Would be much easier if you would tell us what you are trying to do/achieve/get to.
In short, the encoder velocity from the THCAD is feed to PlasmaC component (not GUI) where it is used to control the Z axis position during cutting, this all goes through a PID loop to keep the set voltage value inside the tolerances (usually +-1V) and the output of that PID loop is sent to external offsets component to do the actual motion of the Z axis.
There is much, much more to it, and for that you would have to go through the PlasmaC component on github, several thousands of lines of code there to explain what you are asking.

Take some pictures of the plasma source and upload them here, so at least we have a direction to point to.
Again, do you have anyone to help you with wiring, with electric/electronic experience?
