Peter I followed this to the letter and all worked until the menuconfig.
It complains about a file missing -
scripts/kconfig/lxdialog/dialog.h fatal error . curses.h: no such file
or directory.
It would seem that I need some dependencies. Any idea what to install?
It is a new install of Ubuntu 12.04 from a CD and I have done nothing
but the above instruction to the machine at this time.

Re: [Emc-users] OT: Allen Bradley PowerFlex 40 question
I say the original machine, because we're only using the fixture for positioning the coil, since the machine used a generator to rise the frequency up, a beast that it's now obsolete. We replaced that for a little IGBT unit.

Good luck on the project. > Hello Ray. Indeed what's circulating through the coil is AC, I just gave you the aproximate voltage that the machine uses on the input of the inverter. The machine uses a IGBT transistors to switch a square wave AC and then feed this to an LC tank to generate a sine wave. I really don't know how much voltage is on the coil but I assume is a little one, because there, the current rises because of the transformation ratio. We didn't built it but we were experimenting with induction heating, and I can tell you the tricky part it's how to design the circuit for fire the IGBTs. There are some very good references on the internet if you want to build a heater that's not that big.

It *IS* AC. 10-30kHz AC. And 40A isn't going to cut it. I think Leonardo is mentioning 97A/phase MAINS input. Compute the input power draw. Is typ goes through a high freq stepdown transformer so its only a couple volts AC and hundreds (thousands?) of amps. Takes many many kJ of energy to make that much iron glow in seconds.

Thanks for the reply. I'm thinking about building a little one for my home shop, so I'm interested how they do it in the real world. If I understand correctly, you're running DC through the coil, and it oscillates from 0 amps to 40 amps between at a chosen frequency between 10-30 kHz. I'm surprised it's DC, for some reason I assumed it would be AC. Thanks again for the reply. Good luck on the project.

So you'd have to take that linux-patch-xenomai package (or, maybe better, get the xenomai patch directly from the xenomai developers) and build a kernel package from it.

The minimum we're using is about 40 amps. Voltage is about 650 v when rectified if I'm not wrong because it takes the three phase 380 v from the line. Frequency goes from a minimum of 10 Khz to a maximum of 30 Khz depending on the coil, because it has a phase locked loop to mantain the resonance at all times.

BTW heres approximately whats needed to make a current preemt-rt kernel
cd ~
mkdir rtlinux
cd rtlinux
wget ftp://ftp.kernel.org/pub/linux/kernel/v3.x/linux-3.18.9.tar.xz
wget
https://www.kernel.org/pub/linux/kernel/projects/rt/3.18/patch-3.18.9-rt4.patch.gz
tar -xpf linux-3.18.9.tar.xz
gunzip patch-3.18.9-rt4.patch.gz
cp patch-3.18.9-rt4.patch linux-3.18.9
cd linux-3.18.9
cat patch-3.18.9-rt4.patch | patch -p1
make menuconfig
make
sudo make modules_install
sudo make install
If you accept menuconfigs defaults you should get a working preemt-rt kernel
(this will however make a kernel that supports every hardware device in the
world and its brothers)

So the reduction was only meant to decrease the speed of the motor, and the part turned around at a constant speed. Now we have several types of lobes, we go from 6 mm to 12 mm of lift, and the ones that have that amount of lift tend to overheat quickly on the high point and less on the rest of the lobe. This causes a pretty uneven hardening. > Its a really quick way to heat treat a part! > Indeed, it's beautiful to see how in 7 seconds the part reaches glowing orange.

I re-controlled one of those in the past but we simply rotated the part around the Z axis as the part moved downward through the coil in the Z direction. But then all of our parts were round. Its a really quick way to heat treat a part!

Re: [Emc-users] Delete Debian
I did use gparted, easy enough-select partition-click delete, that worked, but when it boots back up, it still shows it being available in the grub menu at boot. How do I update grub to show that debian is now gone? On 3/11/2015 10:30 AM, Adam McLeod wrote: Hi Rick, It depends on how you have it installed. I assume that you installed Ubuntu and Debian on the same hard drive, but in different partitions. If you haven't put any data you want to keep on the installation partition, you can just delete the partition that contains Debian. To get the space back, you can create a new partition, or grow another partition into the space. I usually use fdisk from the command line. I think gParted will allow you to make the changes graphically within Ubuntu. Then make sure that you grub config is up to date so you can boot back into Ubuntu when you restart your computer.

[Emc-users] new 2.7 prerelease: 2.7.0~pre5
Another pre-release with several bugfixes: * fix vel/acc in non-G17 arcs * fix some TP bugs in rigid tapping/threading * add hal-histogram (shows histogram of hal pin values) * bugfix in stepconf, doublestep now works again * bugfixes in gmoccapy * improvements to xhc-hb04 jog pendant, moveoff, and pncconf * fix 64-bit math in halcompile This one's better than ever, and we're hopefully getting close to a real 2.7.0 release.
