Greetings from a very poor python programmer, begging hat in hand; I have an old lathe that has some bed wear, an linuxcnc has the facilities to correct that. But it takes me surveying the machine for errors as the carriage is moved up and down the bed. Obviously I have to know what the error is, before I can correct it.
The best way is to mount a gunsighting laser in a 38 special caseing in a suitable adapter, and spin it in the lathes chuck, with a considerable neutral density filter in front of it, take a time exposure long enough to let the camera integrate the non-circular beam into a good circular pattern as the spindle turns at 500 to 1000 revs, then close the "shutter" save the image and locate the centroid of that saved image. Is there code to do that centroid math in somebodies "bottom desk drawer"? Something I could download and control with a bash script which I'm fair at? Thanks everybody. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
