[Emc-users] Why doesn't LinuxCNC run? Error log attached.
Just trying to run LinuxCNC to have a look at it and it won't even run. I also tried the latency test and nothing at all happens, *nothing*, not even an error message. Just got done with a fresh install off the 2.5 disk then updated to 2.5.2. I first tried one of the simulation setups, then tried gantry-hs. Then I tried the wizard setup and kept clicking forward until it was done. I just want to have a look around to get a feel for the program. I get this same fail to run every time. 2.5 did this same thing, I was hoping 2.5.2 would fix whatever is wrong.

On Tuesday 25 June 2013 04:08:40 MC Cason did opine: Gene, Since you just LOVE the PDP-11s, this should make your day: http://www.theregister.co.uk/2013/06/19/nuke_plants_to_keep_pdp11_until_ 2050/ That is one of the articles that prompted my tirade. First off, its nowhere near rad hard, and AFAIK only 2 of the older CPU's would qualify, the RCA 1802 family, and the Hitachi cmos workalike clone of the motorola 6809, the HD63C09EP. But thats much newer than the 1802. While the HD63C09EP is a much more powerful CPU, the 1802 was well established, and was enough to get the job done by the time the Hitachi chip came out. And Hitachi's agreement with moto was not for masks, it was to reverse engineer the clone. But they used a different layout, in cmos, and filled the empty spots in the 6809 op-code map with newer, more capable instructions. Like a canned routine to divide a 32 bit value with a 16 bit value, giving the result and modulo 16 bits answers, in 39 clock cycles worst case. Any control computer in a nuke facility really should be rad hard, so that it can continue to function right up to within a millisecond of being a glow in the dark crater in the ground. Those PDP-11's aren't. RCA 1802's are yet today, used in the oil exploration business as part of a downhole surveying tool functioning as the interface between a multi-curie rad source, and an alpha detector that measures the alpha coming back from the rock, which indicates how much oil is in the rock. Operating 6 from a multi-curie src doesn't bother it a bit.

This by the way is a huge challenge for space travel: outside of LEO the radiation levels are nasty and affect heavily both people and electronics. Funny enough, the old semiconductor technology had large cell areas and charges, which gave it relative immunity to charge deposition caused by ionization events. The newer technology shrunk the feature size and unit charges, but it turns out that smaller size makes it harder to hit an individual cell, and also apparently there's more ECC-style error correction in the data paths of the more modern designs, so the bottom line seems to be that the radiation sensitivity did not increase by much. -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Pointless, petty, regulatory BS like that, which has zero bearing on the safe operation of the facility is why the control rooms of nuclear power plants still look like they're 30 to 40 years old - because they are 30 to 40 years old. Modernization and upgrading not allowed, thanks mostly to the green people. What contributed a lot to the problems at Three Mile Island was the light indicating the core vessel pressure valve was open was across the room from where the operators were gathered, looking at the gauges and trying to figure out WTF the temperature kept going up and the pressure kept dropping despite all the water they were pouring into the core. Someone finally noticed the light and hit the manual close button. Problem ended - except for the politics that have kept the reactor from being cleaned up and rebuilt these past 34 years. That's the scary part about old nuclear power plants, many are forced to keep their vintage control and monitoring systems and everything else exactly the way they were when constructed. A decently modern setup would be able to flash an alert and exactly what the problem is on a screen in front of the operators, who could then take any required manual action to correct the problem - if the automatic systems hadn't already. But n, can't have that! Gotta keep plants like Fukushima in pristine original condition with gauges and blinkenlights encrusting all the walls of the control room. It's not just nuclear plants afflicted with this regulatory stupidity. Old coal, oil and gas burning ones are too. George Bush the 2nd tried for eight years to get changes passed that would allow old power plants to be updated with whatever pollution reduction was *practical*. The greens blocked it every time, demanding that the only way any upgrades would be allowed would be bringing them up to current regulations - which would mean tearing them down then spending 20+ years trying to get past their blockade to build new ones. I wouldn't mind having a nuclear power plant, built with the latest technology, close to me. The problem is in the USA they're having to start with a baseline that's 34 years old then trying to get the bureaucrats to approve modern designs. Nuclear power CAN be inexpensive and super safe (it actually *is* safe, the number of death causing reactor incidents can be counted on the fingers of one hand that's missing 2 or 3 fingers*) but only if it's not constantly beset by people determined to make it expensive just so they can claim it's expensive and thus shouldn't be used. *That would be the SL1 and Chernobyl. AFAIK there's been no other reactors, research or commercial power producing, that have exploded. There's been plenty of nuclear incidents that have killed people, but those have all been accidents with radioactive materials or acts of outright stupidity such as a few incidents of people peeling the shielding off RTGs powering old soviet era light houses because they were too lazy to build a campfire to keep warm. -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] Retrofit Candidate Advice
Honestly if the machine is not too far away your best bet is to call your local rollback wrecker companies. They routinely make in town moves of large equipment that they can just drag up onto the flatbed and away you go. That is how I moved my Cincinatti Arrow 500 into my shop. Hell he could even jog the bed and use the flat tow ram to drag the machine off the bed in such a way that he could ALMOST put it exactly where I wanted it. We had an overhead issue that kept him from getting it fully inside the building but he tried and only charged me $150.00 to move it. Then I used some rented machine mover skates to position it in its final place. Some companies don't want to mess with mills and stuff but many do. Just tell them when and where and what exactly it is maybe even send them a picture of it and get the most accurate weight of the thing and they will let you know. It works great for them too because they can schedule it at their leisure unlike a car wreck which often has to be right now. As far as the dowels on the floor. I moved a 4500 lb large lathe with myself and my wife and a come a long on some 1 diameter black iron pipe pretty easily. Just be careful of any grades it can get away from you quick. The nice thing about the small diameter pipes is that IF it happens to roll off the pipe it usually is not high enough to cause a tip over just keep your digits out from underneath it at all times. The mills are quite tall and can be scary to move if you are not familiar with moving larger heavier items so be real careful. That is why I suggest the rollback guys, they move all sorts of stuff all the time and know what the hell they are doing. The guy who moved my VMC made it look pretty damn easy. It did take a larger truck tho due to the 7k+ weight. Good luck man.

Re: [Emc-users] Retrofit Candidate Advice
Andy, Agreed, and the less height and the less you have to maneuver the beast the better off you are gonna be that much is clear. If you have a slab that is nice and level and smooth you can probably do that pretty easy. If he has the rollback move the machine to his shop and then gets it unloaded onto the floor they can push it in with that flat tow ram coming out the back. The one on the truck that moved my cincinatti arrow 500 was able to travel quite a distance. I had carefully lifted my machine before I moved it onto some long 4x4s and bolted them on thru the same large bolt holes that the leveling pods screw down under and made essentially some heavy duty skids. Once he set it down in the doorway to the shop he pushed it as far as he could and then retracted the ram and used another piece of 4x4 to push it the same ram distance into the shop. I only had to move it another five or six feet into position.

The chandelier I'm guessing will weight 200 pound and the winch can be 120 volts I would like to drop, free fall the chandelier 16 to 25 feet then in the last foot or so arrest its fall so it crumples on the stage without actually crashing into the stage floor, then raise it back up slowly. I'm thinking I could just attach a spool to a servo motor and unwind the cable really fast, some question I have would be what motor, how do I size the motor, what controller that's easy to program, how do you guarantee the cable does not get tangled up, how do you make the cable wind up side to side on the spool. Any help or ideas I can get on this project or if you can point me where i can go to learn or get help will be greatly appreciated.

Modernization and upgrading not allowed, thanks mostly to the green people. I don't know how you arrived at that conclusion; it's simply not true. You are correct that this stuff is highly regulated, though---once a plant is licensed for something like 20 years, it's fairly difficult, albeit not impossible, to make changes because it requires proving that the modifications are safe. If it was economically favorable, people would go through the process, otherwise they leave it alone. What contributed a lot to the problems at Three Mile Island was the light indicating the core vessel pressure valve was open was across the room from where the operators were gathered, looking at the gauges and trying to figure out WTF the temperature kept going up and the pressure kept dropping despite all the water they were pouring into the core. Someone finally noticed the light and hit the manual close button. Problem ended - except for the politics that have kept the reactor from being cleaned up and rebuilt these past 34 years. Problem ended, except for the small problem of melting the fuel elements. There was no radiation release thanks to the containment vessel holding up, but inside it was a mess. What do you mean that the reactor not cleaned up? The damaged unit TM2 was declared un-salvageable after few billion dollars of cleanup, but the sister unit TM1 is in operation. Come on, this isn't hard, let me Google it for you: http://en.wikipedia.org/wiki/Three_Mile_Island_accident It's not just nuclear plants afflicted with this regulatory stupidity. Old coal, oil and gas burning ones are too. George Bush the 2nd tried for eight years to get changes passed that would allow old power plants to be updated with whatever pollution reduction was *practical*. The greens blocked it every time, demanding that the only way any upgrades would be allowed would be bringing them up to current regulations - which would mean tearing them down then spending 20+ years trying to get past their blockade to build new ones. This is highly debatable. There's an alternative view, to which I subscribe, namely that GB2's administration was dominated by old-energy lobby and spent 8 years trying to gut the regulations that I personally credit for the nice state of our environment. When they succeeded, like in the deregulation of oil and chemical industry, the results were predictable (explosions at the Horizon platform, and fertilizer plant in Waco). I wouldn't mind having a nuclear power plant, built with the latest technology, close to me. The problem is in the USA they're having to start with a baseline that's 34 years old then trying to get the bureaucrats to approve modern designs. Nuclear power CAN be inexpensive and super safe (it actually *is* safe, the number of death causing reactor incidents can be counted on the fingers of one hand that's missing 2 or 3 fingers*) but only if it's not constantly beset by people determined to make it expensive just so they can claim it's expensive and thus shouldn't be used. We're in agreement here, but the large part of the reason why nukes aren't being built is not the regulation of the plants, but the abject failure to solve the waste storage problem, and the fact that natural gas is just too cheap an alternative. -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

Re: [Emc-users] OT, Programable winch design, need help
Priority number one needs to be safety. Lifting 200 lbs is not a big deal. Lifting 200 lbs when people might be underneath is a very big deal. If something breaks and it drops 16 to 25 feet it could kill somebody. Maybe you already know all this stuff - in that case, please don't be offended. Better safe than sorry. Does the stage already have a fly system? Even if it is manual, having the pulleys and counterweight system in place simplifies things a lot. In any case, I would strongly recommend counterweighting the chandelier. Hang two strong pulleys in the fly loft, one where you want the chandelier, and one backstage or in the wings. Run a cable from the chandelier to the first pulley, then the second, then the counterweight. Make the counter weight maybe 10-20 lbs heavier than the chandelier, so the chandelier will naturally want to go up. Then to drop it, use the motor to lift the counterweight. That way, if the motor fails, the chandelier goes up. The counterweight will fall, but you can locate it in a spot where it can't hit anyone. Everything should be ridiculously strong and overbuilt if there is any chance of people under the load. Breaking strength of all cable, fittings, pulleys, and rigging should be at least ten times the maximum expected load. Use as much redundancy as possible. Pulleys should be hung from the ceiling from strong structural members, using two independent methods of attachment. One that bears the load under normal conditions, and a backup (such as a loop of chain or steel cable) in case the first one breaks or comes loose or slips. The backup loop probably should pass below the actual lifting cable, so even if something crazy happens (like the pulley axle failing), the cable will still be caught by the safety line. Ideally you would never let it be above people at all. Perhaps you can drop it at the very front edge of the stage, and instruct the cast to never enter or cross that spot. Be very cautious about lifting and especially holding any significant weight with a servo. If the drive shuts down or trips out for any reason, the weight will drop unless the motor has a brake, AND the brake is properly interlocked with the drive, AND it works correctly. Holding a weight stationary is typically harder on the drive and the motor than making the same torque while spinning - that just increases the risk that the drive might overheat and shut down. My gut tells me that it will be very difficult to slow the falling chandelier without it being very obvious. The mind knows what a falling object should do, and is pretty good at detecting unnatural behavior. The control can be done in HAL if you want. It isn't hard to set up a servo loop with a PID controller. The position command could come from hal-streamer, which would let you define a position vs time profile using something as simple as a spreadsheet, and play it back exactly as many times as you want. You could experiment with different profiles to try to get something that looks as natural as possible. Making the cable wind evenly side to side can be done with a level wind mechanism. If the cable is short and thin and the drum is wide it can be a simple threaded rod 6 inches or so in front of the drum that is belted or geared to the drum, and moves a guide across the drum. For example, assume you are using a 1/4 cable, and your drum is 4 in diameter. One turn of the drum means 4 times pi = 12.56 inches. Call it a foot. To handle 25 feet of line, you will have 25 wraps on the drum. If each wrap is 1/4 and you want to have a single neat layer, then the total width of the drum needs to be at least 25 times 1/4 = 6.25 inches. If your level wind uses 3/8-16 threaded rod, it will take four turns of the rod to move the cable guide 1/4. So the threaded rod needs to turn four times for every revolution of the drum. Small timing belt pulleys would work for that. A couple years ago I built a system somewhat like this. I was lifting a much smaller load - a prop that weighed less than 10 lbs and was bulky and rather soft - so I didn't have the same safety concerns. I used three winches with a kinematics module in HAL so I could control the prop in three dimensions over a fairly large working envelope. I was using kevlar line that was about 0.035 in diameter. I used 1/4-20 threaded rod for the level wind, geared roughly 4:5 with the drum. So the 0.035 line wound onto the drum at about 0.040 per turn. The drum was over a foot long, so I could fit at least 300 turns on it. The drums were made from 4 schedule 80 PVC pipe with plugs for the motor shaft on one end and a bearing on the other. The OD of the pipe was about 4.5, so when completely wound up I had over 350 feet of line on the drum. The motors were some beefy NEMA 42 steppers with microstepping drives. Even with my much lighter load, powering down the stepper drive would allow the string to unwind and the load to drop, Here is some
