Scannermax 506s

[WolfMax]

Yes, the 'Pro' uses the same position sensor as the Saturn family, so is more accurate.
It was covered in some thread, either this one or the one that was the precursor to this one (before Steve and I got ours)

Ok, so all the talk about 50 degrees and 90k and all the super stuff the 506 has been heralded to do, is that only with the "Pro" version?

I think 90K is really only going to be had out of the Saturn I not the 506c's mainly because of the longer shaft and superior torque. I believe the pro version of the 506c has better linearity, not exactly more speed.

All the talk about 90k on other threads has been to do with the Saturn galvos. Bill has never claimed anything about the 506's other than them being a great 30k scanner capable of wide angles.

All of the videos and 'review' on this thread [so far] are using 506's with the standard position sensors (albeit small production run of prototype sensors)

[WolfMax]

I stand corrected about the 90k

I suppose what's really concerning me is that reference to the 506 is just that '506'! But if there are 2 types with differing performance (and no doubt different price), how are we to know what we can expect if we buy a set when we don't know which set people are talking about?

As Norty said.

Both 506's will probably manage the same speed and angle, I can't see the position sensor making any huge difference there. The difference will be most likely in repeatability. So if you want razor sharp delineation in fans or need to hit beam targets over and over again, then the pro version will be the one for you. If you just need a cracking good wide angle 30K (+) scanner (exact speed dependent on the new amp mods), then the standard 506's will probably float your boat for a little less cash.

Personally, for the likely difference in price, I'd probably go Pro as I've witnessed 1st hand the improvement of Cambridge over DT's at the same speed. That said, the standard 506's I expect will be far better than DT's in any event, so the gap may be narrower here. We're not going to know for sure until we can see both types side by side.

So far the only ones that are 'out there' are the standard ones, so you don't need to worry about what people are talking about yet.
The sensor shouldn't affect anything other than position repeatability so you're unlikely to notice much difference anyway.
I suspect that you probably won't see that many 506 pro versions anyway as people who will require that extra but will be buying the Saturn variants. I remain to be proved wrong.

When I took the Pango office tour, the 506 PRO vs the 506 is the same rotor, same stator, same coil, same mirror. The high end position sensor is the sole difference. Speed will be very much the same, the targeting accuracy improves.

For large mirrors and slow scan speeds I understand the 506 is actually better than the Saturn due to the torsional stiffness of its thick and short rotor shaft. If shaft twist causes the position sensor to operate a little out of phase with the mirror (depends where these two are relative to each other on the shaft) then there may be a dynamic component along with a accuracy or resolution component to take into account as well. Also, I don't know how frequently the position input is utilized. Even if the mirror is running ballistically , is the position sensor feedback so rapid that the driver is modifying the "flight path" of the mirror? Furthermore, how much better is the pro position sensor ie 99.999 vs 99.9?

I just purchased 2 sets of 506s and sent my scanner amps to Bill for modifications. When they arrive, one set will be replacing some bad DT40 Pros, and that projector has an identical twin, making it possible to do a side-by-side comparison with the DTs. Stay tuned!!!

so how much does this cost anyway?

I' ve seen hints here and there, but no "hard data"
