![]() 2312 forum posts 112 photos | Over on 'Homemade Tools' is a piece on using a pen microscope in the machine shop; I've had a look on a well known auction site and there seem to be some very cheap ones. Does anyone know if the software is likely to be compatible with Windows 10 and how could it be mounted on a mill? Brian |

![]() 2312 forum posts 112 photos | Hello Paul, yes, I know there are edge finders on Ebay and I already have a Starrett wiggler and an electronic one but the item described on 'Homemade Tools' is in a different league altogether and is more like a shadowgraph. Thanks Martin for the digital pen info, I'll look into that. Brian

5563 forum posts 322 photos | I went through this process on my little CNC mill, mounting a CCD microscope on the side of the column and using the CentreCam software. Obviously the 'scope centreline is offset from the spindle axis when you do this. In order to evaluate the offsets I used the following process.
However I have never found the method very useful because it's a faff and manual, much better to have a probe linked to the controller and find the edge or centre automatically. You can see some pics in my "Microscope" album. Edited By John Haine on 21/11/2020 10:02:39 |

![]() 2312 forum posts 112 photos | Many thanks for your input John, I did wonder about the offset between the camera and the machine spindle and wondered if a WiFi camera could be the answer, held in an ER collet on the machine. Brian |

![]() 2549 forum posts 235 photos | I tried CentreCam and a webcam camera as well. Tried to make a suitable spindle mount and found it so hard to set it on the centreline of the spindle You can set it on the centre line at one height then find it is not right at another height so try again to centre it, repeat this process a few times and give up. Effort involved compared to potential return was too high so gave up on it. Martin C |
