Re: [Emc-users] Running on a G4 MAc (new world)
Hi Jason, just some snippets from the RTAI mailing list: (Thread called [Rtai] rtai on a ppc405 (Xilinx XUP Boad) from the 1st February 2008) - Is it possible to use a newer Kernel than 2.6.14, are there any more patches? At the moment no. Newer patches requires adapting to Linux powerpc framework, not ppc. With the hardware I have, a small 9 year old G3 portable Mac, the only witness of externally gifted hardware support in all of the RTAI history, compiling and testing the kernel and RTAI directly on it is a bit of pain. I know I should install a cross development environment to speed things up, but at the moment I've little time and space to make it ready to use. The only witnesses I know of the use of the latest RTAI for PPC are on G3 and G4 UP CPUs, 7xxx series I think. Notice that it is just for UP at the moment. There is an effort underway on a Mac G5 but is still at the verification stage using 3.6, the ppc environment and 2.6.14. It should end on powerpc environment and thus more recent paches but I've no scheduling authority on it. On my side I've a plan to use ppc/powerpc on a new project but I'll talk of it only if I'll be able to make it take off. Paolo Reading that thread, it seems you should start by using 2.6.14 and RTAI 3.6. Let us know how things go along.

Re: [Emc-users] Stepper torque measurement article
aram, It would be easier to measure current to the motor as this would be what creates the torque. Current measurement is easy. If you want to truly measure the torque, it is done either with a strain gauge on the shaft or with a spring coupled drive and measure the deflection of the spring. Either way, you need a pair of slip rings to get the information to the outside world. These are noisy and will be hard to use. bill [EMAIL PROTECTED] wrote: Hi Can you measure torque on AC servo motor? - This SF.net email is sponsored by: Microsoft Defy all challenges.

The only witnesses I know of the use of the latest RTAI for PPC are on G3 and G4 UP CPUs, 7xxx series I think. Notice that it is just for UP at the moment. There is an effort underway on a Mac G5 but is still at the verification stage using 3.6, the ppc environment and 2.6.14. It should end on powerpc environment and thus more recent paches but I've no scheduling authority on it. On my side I've a plan to use ppc/powerpc on a new project but I'll talk of it only if I'll be able to make it take off. Paolo Reading that thread, it seems you should start by using 2.6.14 and RTAI 3.6. Let us know how things go along. Maybe we should move this thread over to emc-developers Good luck best regards, Alex - This SF.net email is sponsored by: Microsoft Defy all challenges.

The OS X system, whilst similar in many respects to Linux/GNU (it is, I believe, a BSD derived build), Linux kernel code will not work. 2. install ubuntu 6.06 as that is the lattest for a PPC class cpu. i think i still remomber how to manualy do a patch from the rtlinux ad NIST days. at least i know linux :). If you *really* want to go with Linux, might I suggest going for Debian - You can always upgrade to Lenny (or Sid) if you want testing/unstable/experimental packages without waiting for them to appear in ubuntu. To be honest though, if you already have a distro installed and running, why change. 3. unknown to me at this stage. either way, it should be this week that i start to give it a go Keep the original OS X install, then you have a chance to compile and test for both environments (and we get to see were things go tits up).

Re: [Emc-users] Stepper torque measurement article
what about a spring coupler and 2 encoders? and do current measurements while exerting known levels of torque, make a chart so you know how much current = how much torque, use current monitoring... isolated ADC across shunt resistors for each phase of each motor be it AC or DC. It'd jsut be quite a few inputs to watch, and might end up being not the fastest of all. i know from watching the load meter on the mills at work that you can easily see a change in the trend when the tool's wearing. so if you could script it to alarm when it's increased by X% from an average of the first number of runs on that tool. I know the new fadal's my work has does have spindle load limits for you can set for each tool... Sorry if this has been a long ramble, i guess i'm getting all i can out of 'computer time' before i have to go do the dishes hehe...

If you want to truly measure the torque, it is done either with a strain gauge on the shaft or with a spring coupled drive and measure the deflection of the spring. Either way, you need a pair of slip rings to get the information to the outside world. These are noisy and will be hard to use. bill [EMAIL PROTECTED] wrote: Hi Can you measure torque on AC servo motor? - This SF.net email is sponsored by: Microsoft Defy all challenges.

Ensure that the rings are rigidly fixed to the shaft and you will find that you will get a varying phase difference between the output of your two pick-ups as the shaft twists under torque loading. No noisy slip rings :-) . Cheers, Geoff. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Emc-users] Request for Fonts
I ran across a macro written in Visual Basic that can be installed in Autocad that seems to do a pretty good job of converting polylines into gcode. Using creating text in autocad then selecting Expresstextexplode, then Modifyexplode, then using the pedit command convert and join the lines to polylines, then run the gcode converter after you install it. It spits out the gcode you are looking for.

Re: [Emc-users] Stepper torque measurement article
On Monday 11 February 2008, Dave Engvall wrote: Spindle load is certainly one way to do it. Whether you do spindle load or force your cam is going to have to do a good job of keeping the cutter load constant or you will end up setting the trip too high to do much good. The same is true in trying to control such things by setting following error rather tightly. Dave Running steppers here, so there is no feedback from that. And it could have been useful yesterday as I was cutting the crush slot in a boring bar holder, the cut involved going about 1.25 deep from open end to open end with a std 1/4 end mill that had been sharpened till there was only about 5/8 of flutes left. A particle of swarf apparently got jammed between the shank and the slot wall, stopping my 4 ipm x motion. Backing away by hand allowed it to clear, but then I had to rezero the x axis, edit my routine for the then current depth of cut to restart it at, and it continued till it was done with no further issues. I was cutting about 10 thou deeper per pass each way, at around 500 rpm. Trying to keep the chips big enough to not constitute a nanoparticle hazard. Or in my hands, virtually invisible but painful as hell. Lubed by a couple of drops of cutting oil per pass. Too cold to plug in the air compressor since I'd have to leave the door open, its outside under the roof overhang, with a tarp over it ATM. I need a shop about 4x bigger. Don't we all? But using the finished boring bar, I've found about 75% of the motor mount I just knew was hiding in a 3.2x3.2x4 block of alu. I should have put a fresh chip in it though, it sings to me leaves a stippled finish. Now I have to turn it around in the 4 jaw, relocate it and do the other ends last 3/8, drill the motor mount and flange holes mill away the sides to clear the mill table when the rotary is mounted to it. Then switch the 3 axis card for a 4 axis, pull the 262 oz/in z motor from the mill and replace it with a 430 use the 262 on the rotary table. And plug in another parport card I've bought so I can use the 3 axis card on the lathe eventually, which would have made that boring job a heck of a lot more precise. And, I obviously need to cut an allen wrench down for a very short short leg so I can reach the carriage adjustment capscrews which are only about 3/8 above the lead screw, I could see it bouncing a bit last night after I'd pulled it down hard enough I had a heck of a time restarting the carriage onto the ways. Way wear in the middle I 'spose, there's a lot of time on that little 7x12, I've refinished the bottom of the carriage once already. The factory way fit was atrocious, wrong V angle by a couple of degrees so the wear was very high initially. Subject to being replaced with a bigger lathe IF I can get my sugar under control, we're still working on that. Then I can start playing with 4 axis's on the mill. 8:) There are a lot of things I have left to do, hopefully I have the time left before I fall over. 73 and diabetic, so who knows...
