I’m impressed! I got side-tracked and am narrowing in on a solution now (about to 3D print a prototype next week). I was inspired by the €35 T-Slot copy stand kit - https://www.dold-mechatronik.de/Reprostativ-V5-kit, but as mentioned previously, looking at a horizontal setup. I’d have bought this kit, if it wasn’t + €55 to ship to me in SoCal.
After talking with a couple of local T-Slot vendors, one design specialist made an inspired suggestion, and I’m working on that at the moment (flat custom plate at end of T-Slot). As I will only be using a single camera, some of the flexibility in your rig (especially the tilt adjustment of the EFH) I won’t need (I hope, as I can do a one-time alignment (shim or file end of T-slot, or ??) and be done). My mount should handle Y&Z axis adjustment, and I was thinking of a XR linear stage trimming platform for the camera, with R possibly being unnecessary?? From lurking /reading last few months, the sensor to film distance (ie getting focus perfect) as well as alignment is key. Hence thinking a X-axis micrometer linear positioning stage / trimming platform would help. I’ll update once I have a working setup.
What did you use for aligning sensor to film? mirror, or ?? Sorry, I don’t see how a digital level would work for this? I came across a test negative using USAF calibration markings, and was wondering if that would come in handy, or is complete overkill
