[Emc-users] An alternative way to make encoders.
I recently got some Avago AEDR8300K encoder sensors. These have two detectors in a small SMT package for quadrature in one device. http://www.avagotech.com/pages/en/motion_control_encoder_products/incremental_encoders/reflective_encoders/aedr-8300-1k0/My plan was to laser-print a target onto adhesive vinyl and use that as the target, but unfortunately it seems that these sensors require a very shiny target (specular reflectance 60) with not-shiny parts. White paper is not there to these sensors. Polished aluminium is very much there but so is polished aluminium with black marks on. After some experimentation I found that polished aluminium with an etched pattern works very well, though. So I CNC-marked a polished encoder ring and etched it in FeCl. This looks like it is going to work very well indeed, and was a lot less trouble than milling (and more suited to the dimensions of the part)http://youtu.be/c1zCG-uPaoM I will see how the pen-drawn version works out, but the idea ought to work fairly well (and at much finer pitch) with photo-resist methods. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. -- Ridiculously easy VDI.

Re: [Emc-users] hal taking machine down
If you want the ultimate in low writes, install your OS as a 'live' CD image. There are plenty of instructions on doing this with a thumb drive and they apply equally well to an SSD. You can have a separate partition for your data. I ran my network server like that for quite a while. Some distros have an option to save the current RAM drive state on shut down so you only write to the card on shutdown. Windows XP Embedded does something similar. Of course if you have a power failure you lose your recent data. Les On 04/01/2012 17:49, Peter Blodow wrote: I use an 8 GB SSD as a boot device in my ISDN monitor, an old, slowed down Pentium PC.

Regards, Kent It really isn't just a CPU cooling issue. Usually the entire enclosure needs to be cooled. The cheap industrial way to cool a cabinet is to use a Exair type vortex compressed air powered cooler. They are relatively cheap, and bulletproof, but they eat a lot of compressed air. But if you have a lot of compressed air available, then that can be a good solution. In general, I like to keep water away from electronics and high voltages... :-) Although... the low rider lighting is attractive.. ;-) I have worked on a few high power induction heating units that use water to cool just about everything, including the power conductors. I find them a bit scary. 480 volts, SCRs the size of hockey pucks, mixed with hoses and water all in the same cabinet!

Re: [Emc-users] Riser for Intel Mini-ITX
Just an FYI, I have an Intel MD525MW motherboard, 4gig ram, and disk. The smallest case my supplier could get had a small fan on the power supply, and a fan for case cooling so I guess I could say that my motherboard is fan-cooled, but that's just life. Had to turn off hyper threading on the motherboard; otherwise, I think that's it. My G540 and 48v power supply is in a different case; this one came from an old-school 6gig disk drive; the fan was replaced with a 48v fan. This box sits on my mill stand, and is painted to match. Makes for a nice, clean installation. JohnS Canada. -- Ridiculously easy VDI.

Re: [Emc-users] ur steppers
On Thursday, January 05, 2012 03:36:36 PM Cathrine Hribar did opine: Hi gene Wanted to ask where you found your steppers? I see that they pull 6 amps, what is the voltage and size? Thanks Bill I bought all those from Jeff at Xylotex, 3 ea of the 262's he had originally, then bought a 4 axis kit with 425's when I needed to add a 4th axis. And 6 amps might be what the 425's need when wired parallel. They are 8 wire, in series currently getting about 2.35 amps/phase. The 425 motor on the Z drivers ios the only 425 installed ATM, and could do more than that 2.37, but ISTR I had them set for 2.4 amps/phase when I cooked the 4 axis Xylotex board so as that seemed sufficient, I set the new MM-542's for about that same (2.37) amperage. The 262's are sometimes called a double stack as they are long, and the 425's are often called triple stack because they are even longer. I have to open my new drivers box up, as the A axis is running at 100% current full time, one of the dip switches must have gotten bumped, but when I do I may as well set them all up to 2.84 amps. They can go to 4.2 amps, but that may demag the rotors I'm told. But with 20 tpi XY screws, I doubt I'll gain any advantage in rapids. I am pretty well voltage (28) and rpms at that voltage limited. A 36 volt supply would help but those are generally make it yourself, with 3x more in parts than I have in the 28 volt switcher with 5 12 volt low current outputs in there now, about a dollar a volt from All Electronics.

I just looked at that pix again, and that says 5.0 Amps, parallel. But that is not the motor on the A axis now, I downgraded it to a 225, runs it just fine weighs half a pound less. So I probably shouldn't set it to 2.84 amps, could well be too much damage the rotor since the series wired current max then would be only 2.5 amps. It can put 155 pounds on the end of a drill bit as is, good enough I think. The 225's can take the 2.84 amps IIRC, but those puppies don't have a label of any kind on them. All I can recall for sure is that they could take everything the Xylotex could throw at them, which is 2.5 amps.

Regards, Kent And likely to remain so unless somebody comes up with a whole new technology whose switching losses are 10% of what we have today. In my case, 28 volt supply, times 2.37 amps=66 watts circulating between the driver and motor. I'd estimate the motor is converting 40 watts of that to heat from i2r losses while the driver is using 20 in switching time losses with the other 6 watts being wasted in the semiconductors on resistances, commonly down in the milliohm range these days. There probably is not a heck of a lot we can do about the motors eddy current and i2r losses and that is today, the almost veto proof majority.

I see that they pull 6 amps, what is the voltage and size? Thanks Bill I bought all those from Jeff at Xylotex, 3 ea of the 262's he had originally, then bought a 4 axis kit with 425's when I needed to add a 4th axis. And 6 amps might be what the 425's need when wired parallel. They are 8 wire, in series currently getting about 2.35 amps/phase. The 425 motor on the Z drivers ios the only 425 installed ATM, and could do more than that 2.37, but ISTR I had them set for 2.4 amps/phase when I cooked the 4 axis Xylotex board so as that seemed sufficient, I set the new MM-542's for about that same (2.37) amperage. The 262's are sometimes called a double stack as they are long, and the 425's are often called triple stack because they are even longer. I went to Jeffs page and found that the motor I've been calling a 262 is actually a 269, and it has a 2.8 amp/phase rating. I also hauled the drivers box down to the garage and found out why the ABC motor was running hot. It had the 50% throttle when idle switch set ok, but the switch next was miss-placed so it was getting 4.2 amps when moving, but it never lost a step so I doubt the armature was hurt. and 2.1 when idle. Set them all to 2.84 amps left it running idled for about an hour with heating of about 7 or 8 degrees, since that is only 1.42 amps when idling. Sweet. But that new D525 computer will be next Monday getting here, so I'm still figiting about. I don't mind wasting time, I am decently good at it, but I hate enforced idleness. I also booted the old box and found its latency sucked, just moving the std sized glxgears window around on the screen took the jitter from 16 u-secs to around 120 u-secs. Where can I find some real docs on this isolcpu thingy? Thanks all. Cheers, Gene -- There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
