N_Cook <diverse@tcp.co.uk>: Dec 23 04:40PM It looks as though tightening torque would be very critical. About 1/2 turn off opposing set screws changes the image about 70mm at 100m. Decided the way to do this is to measure one side only vertical and horizontal , the side where the moving brass block is exposed beyond the mount , so easily measured diametrically. First attempt went approx same error the other side of zero. So adjusted to half the measurement and then make final adjustemnt by varying the finger-tightness of torque to the opposing set screw, before a dot of laquer. . |

You can write a contract pretty well any way you like. It's pretty tough to enforce a hardware EULA on something you bought at a tag sale though. ;) Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC Optics, Electro-optics, Photonics, Analog Electronics 160 North State Road #203 Briarcliff Manor NY 10510 hobbs at electrooptical dot net http://electrooptical.net |

Not uncommon nowatimes for software distributors to only allow software to be downloaded to a machine that has an Internet connection using a special installer, keyed to the hardware configuration of the machine and run on that particular machine. If you want to install on a machine with no Internet connection, or download on a machine with a faster connection and transfer you're out of luck. If your hardware configuration changes whether you're out of luck or not depends on if the software-seller feels generous |

Good luck doing that after decapping the flash and reading it out via SEM. ;) Cheers Phil Hobbs -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510 http://electrooptical.net http://hobbs-eo.com |

LinuxCNC has added a number of features to the basic G-Code language, turning it into an actual programming language. So, you can write G-code that is "parameterized", so you can set a few variables and then the G-code loops and computes the actual coordinates based on those numbers given at the start. In your specific case, you would enclose YOUR entire G-code program within a couple lines, like this: #1 = 500 (do 500 parts) O100 WHILE [#1 GT 0] < your program goes here > #1 = #1 - 1 O100 ENDWHILE M02 See http://linuxcnc.org/docs/html/gcode/o-code.html#ocode:looping for more info. But, the sceme here is you set user variable 1 to 500, then the WHILE loop executes your program 500 times, and decrements variable 1 at the end of each run of the program. When variable 1 decrements all the way to zero, the machine stops. And, to get tricky, LinuxCNC has a virtual control panel that can put indicators and buttons on the screen. I use it to show touch probe status and spindle speed, but you can put nearly anything on there, such as the value of that variable. > programs will work the same without needing any changes.

That may involve adding a couple IO points to the hal configuration, but could certainly be done. Jon |
