Re: [Emc-users] Mirror Grinders.
Hello Andrew, you are so right! Making large diameter (300 mm) grinding tools of large radius of curvature (e.g. 6000 mm) was my reason to join this mailing list. In fact, I turned some on my lathe almost 20 years ago with steppers replacing the hand wheels and all driven by home made BASIC programs. The grove net was then cut by hand with an angle grinder. But: turning the tools out of slabs of cast iron makes more sense than trying to cut or grind the glass directly by means of numeric control. You must have metallic grinding tools anyway if you are to make more than one mirror (or lens). Furthermore, there is no means other than fine grinding to achieve smooth surfaces like the ones needed in optics. Without fine grinding, you can't make a surface true to 1/10 of a light wave, not even with EMC2. But you (almost) can't make a spheric tool without something like EMC2, either! Some time, I will finish this job - the telescope is still waiting for its lens and mirrors Speaker To-Dirt schrieb: > Hey Kirk: > > I used to work at a large optical lab.

Re: [Emc-users] Wichita fest
Ok - I want to schedule the Wichita Fest for Friday 12 Nov 2010 thru however long anyone wants to stay the next week. The shop is working 4 days so we should have Friday, Saturday and Sunday to work on projects without much interruption. We can stay during the next week and work around everyone. Most of the shop thought it was a neat deal last time. I fielded a lot of questions. There are a number of cheap (not 5 star) motels in close proximity. Come for the fun. Bring a project to program, wire and/or machine. Please let me know if you are coming so I can arrange room, electricity, tables, etc. thanks Stuart On Thu, Aug 26, 2010 at 8:21 PM, Jon Elson wrote: > Dave wrote: > > That is the right thing to do...

I have exactly the system you describe. I started with a VMWare Lucid install on my Mac (based on a downloaded ISO) I then used the "Startup Disc Creator" that is included in Lucid to make a bootable USB stick, (System->Administration->Startup Disk Creator) to make a bootable Lucid USB stick. I needed to make a couple of BIOS changes to get the system to boot from the rear-panel USB slots, but I think that the front panel header is meant to support USB drives by default. However that is unwired on mine (and probablu yours) and the others worked. I recall a bit of messing about to get the drive bootable, I think it has to be FAT16 for example. Once the machine is booted you can install from a script. You will soon be able to create a bootable Lucid USB stick from the LiveCD image, I think, which will save a few steps. Currently the LiveCD is Hardy, which has been perfectly OK as a CNC OS for the last couple of years. -- atp -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.

Re: [Emc-users] Mini ITX systems
Andy, There is no reason why you cannot connect a Sata or USB CDROM drive to your system, install the OS and then remove the CDROM drive. Get the latest EMC2 live CD and boot the system off the CDROM drive, then have it load the system right off the live CD. You can't get any simpler than that. I have a portable USB CDROM drive that I use all of the time just for that purpose.But you could temporarily plug in a Sata CDROM also. The Pico power supplies work fine and so does the 510 board.

Re: [Emc-users] Mirror Grinders.
Yes simple rigs can give you a sphere, nature gives that one to us. You can do it by hand up to a meter or so in diameter. It took a few decades to develop optical tests and parabolizing strokes to take the sphere and grind it to a parabola, and nowdays, secondaries can be hyperbolas. A sphere does not make a good imager unless the focal length is huge compared to the diameter of the mirror. It's why old telescopes are long. But then f5 and greater system are still parabolic primaries. I don't think you can go spherical only until you start playing with f10 or greater. you could use a Dall Kirkam, but you need some image field correction still. The machine tools used in mirror grinding are not encoded to twice the limit required on the glass as called for by Mr Nyquist. All the optical grinders I've worked with are close to run open loop along these lines. There is a model by which glass is removed. Foccult testing and Hartmann testing give you the high and low points on a mirror. Strokes with a given grit are computed to remove the high surfaces, and then run on a machine that may only be encoded to 0.010 inches/tick. You run the stroke, then run another optical test, then compute another stroke . You keep going until the error is within acceptable limits.

Well - I fail at copy and paste... this should work better. I thought I would give an update on our ongoing project. This is a 60's vintage NC that used hydraulic servos. we are converting it to EMC2 using not quite as old Inland servos. (80's vintage) they are 8 brush low rpm high torque. (with the amc drives we are using - it will be 40ft-lbs peak.) We are using 2 mesa 5i20 boards as we are needing a good 70+ i/o + atleast 7 encoder counters and 5 +/-10v outputs. We are at the point where the machine is waking up. the mesa hardware is awesome (thank to peter and seb for their work). Be sure to watch the 2 videos at the end of this email. lets see if I can create a linear picture show... this is what the machine looked like in the 60s http://electronicsam.com/images/KandT/oldkandt.JPG this is what the machine looks like now http://electronicsam.com/images/KandT/DSCCurrent.JPG getting rid of the old control http://www.electronicsam.com/images/control.jpg this is the old electrical box http://electronicsam.com/images/KandT/conversion/mainelectricalbox.JPG we welded 2 of the same boxes together for new electronics. http://electronicsam.com/images/KandT/conversion/moreelec.jpg here is it mostly hooked up http://electronicsam.com/images/KandT/conversion/mostio.JPG This is the x,z,b gearbox - the old control used 1 hydraulic servo to run all 3 axis http://electronicsam.com/images/KandT/conversion/xaxis/start.JPG open http://electronicsam.com/images/KandT/conversion/xaxis/start.JPG stripped http://electronicsam.com/images/KandT/conversion/xaxis/stripped.JPG shafts extended out so we can hook the servos up. http://electronicsam.com/images/KandT/conversion/xaxis/3shafts.JPG servo plate mounted http://electronicsam.com/images/KandT/conversion/servo/x-zservo_mount.jpg belts (B axis still needs a solution) http://electronicsam.com/images/KandT/conversion/servo/belts.jpeg Because we are still using the z axis drive train that goes up though the saddle - we needed to get the backlash out of it.

Hi Andy: I may be showing my ignorance here, but while searching on your motherboard, because I'm about to do the same thing you are, I found this http://www.newegg.com/Product/Product.aspx?Item=N82E16813121399&Tpk=D510MO Where's the parallel port?

[Emc-users] Fwd: EMC in joint mode?
Hello, guys! I still would like to find out, how can I make my machine safer and at least disable jogging in joint mode, but I did not receive any answer. I would really appreciate, if anyone could share some insights on how to achieve that. See below forwarded initial message for more details :) with best regards, Viesturs -- Forwarded message -- My machine has a gantry setup and there have been several situation, when I accidentaly start jogging it before I switch to world mode and last week I noticed that EMC sometimes swithces from world mode to joint mode, when I go from "manual control" to "MDI" tabs on the left side of the screen. So I wanted to ask: 1) is there a way to disable jogging, while in joint mode? what I actually would like to achieve is - start EMC, home all axis and automagically switch to world mode and do not allow switching back to joint mode. Is something like this possible? I think that situations, when machine is in a position, where separate joints have to be jogged, are special cases and I find totally acceptable to change some settings in ini/hal or any other files before doing it and then set it back. 2) what information should I try to get, if this unwanted world-to-joint mode switch will happen, when I will just switch from "manual control" to "MDI" and back? when this thing happened, I clicked several times to go from one tab to another and back and so on, but then it behaved as it should - remained in world mode. I noticed it, because I started to jog the machine and it started cracking as only one motor on the gantry was turning. It seems to me that it might be very easy to destroy the machine, but I do not know, how to reproduce this error.

Well, the beauty of the eccentric mirror polishers is that the kinematics of the polishing process make the mirror surface ideally spherical.

This looks like something EMC2 could be used on: http://www.mirror-o-matic.com/machines.html , maybe to simplify the mechanism or allow for more sophisticated or randomized sweep patterns, automate grit and fluid. I have a 6" mirror from a 1970's project I'd like to finish. A vacuum chamber for aluminizing the mirror would be fun to make too, but adding projects to try to finish projects is not a good sign. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- Sell apps to millions through the Intel(R) Atom(Tm) Developer Program Be part of this innovative community and reach millions of netbook users worldwide.
