Re: [Emc-developers] RPi users LCNC
Just a warning, we had issues with a step/dir servo machine made with JMC integrated servos. They are way to slow controlled for a decent machine. Position loop is only 200Hz. This resulted in bad Path following => very ugly surfaces.

Re: [Emc-developers] 2.8 Situation
Ah yeah, here we go. Again. Open source =! Non commercial And please don't think that Beckhoff would pay for your wrecked machine even if they fucked it up. There is no warranty that covers you. That's why I prefer open source. I can look myself if I have to and pay someone if I'm able to. The latter is missing here. Let's fix it. And there is little sense in keeping improvements to lcnc to myself. The usual customer makes money with the machines working.

Re: [Emc-developers] 2.8 Situation
Moin! Oh, believe me I know what you mean. And, I am just stating my personal opinion. But you are confusing open source with non-commercial. And linuxcnc is a commercial software. Because it is used to feed loads of people in loads of machine shops over the world. And if you disregard this you make linuxcnc not better, but useless. You can't rely on those spenders who can pay in code lines. You have to use all of them, also those who only have dollars and machines...

Re: [Emc-developers] 2.8 Situation
Moin! (north german hello) I would like to add some thoughts. 1. Releases are a must have. Think about someone having a 1 Dollar Maschine being brocken by a Bug. I for myself am very cautious about testing new versions, as my machine has 2x 2KW servos on y-axis, easy able to tear the machine apart... 2. If there are spenders, bring them on. What about a patreon for lcnc? And payment is done in 3 tiles, one in advance, one @integration and one @release. We make a list of open things, define a price and publish them. I for myself would be OK with the one organizing getting paid for his work. 3. Mark Shuttleworth may be interested in sponsorship along with Ubuntu? I think we have the usual problem, communication issues. It the spenders and the developers would have a platform.

These are in the $30 region for 75W peak 40 ns pulse width, not much vibration or motion blur in 40 ns :-) the problem is not the vibration in the 40ns but that the recorded encoder image is more or less a random position within the vibration range of the device + vibration of the laser - I was thinking about compensations like done with satelite images where multiple pictures are taken and then the signals are compensated by filtering out szintilation effects If the actual sampling is in the multi kHz range only then that would be well in the modes that such systems can have and one - worst case - would have the full vibration in the positional information. Just wonder if there are any detection algorithms that look into such issues. Naively one could do a fft on the position data under the assumption that motion should be constant/known-trajectory and that could reveale such vibration/aliasing induced errors. http://www.osram-os.com/osram_os/en/products/product-catalog/laser-diodes/high-power-laser-diodes/pulsed-laser-diodes/hybrid-pulsed-laser-diodes/index.jsp ( thank you Harold Edgerton ) thx! hofrat -- ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers -- Diese Nachricht wurde von meinem Mobiltelefon mit Kaiten Mail gesendet. -- ___ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers

Reading the datasheet: http://datasheet.octopart.com/ADNS-9800-Avago-datasheet-10666463.pdf Page 13: Path deaviation It seems that a homogenous surface puts down the error to ~1.25 / 1600 inch / inch with an optimum @~0.8 /1600 inch / inch with photopaper and a sensing distance of 2.25mm. All at a relatively low speed (6ips) Combined with a rough syncing (every 2mm) - using a frame capture of the sensor - you shall be able to get pretty high resolution with a minimum of effort. The sensor itself works up to 150ips and 30g, what the resolution and deviation there may be... I dont know.
