First video of my Liteplacer mod in a small test run with th

Hi
Finally I got my Liteplacer + OpenPNP mod mostly operational. Here are the first few specs:
• 750mm Y Axis (instead of standard 500mm)
• Y motor upgraded to NEMA23
• X motor exchanged for faster 1.8° stepper
• Smoothieware firmware
• Azteeg X5 GT controller (+ donation to Smoothieware)
• Trinamic TMC2660 stepper drivers (+ tons of much-needed tuning)
• MPXV5050VC6T1 vacuum sensor
• 2 x ELP 6mm 2MP Full HD High Speed MJPEG USB Camera Module
• Z Probing Liteplacer style in OpenPNP (no part heights needed)
• Open frame base design (with some extras …)
• Sunken nozzle tip holder, flush with bed (banged it too many times)
• A surprising amount of work, brutal learning curves, at times a roller-coaster of emotions!
I hope to document all this much more and I will post all my config once it is really working in earnest.
The test run uses all the vision features just as a demo. Small parts (only tried 0603) can be reasonably placed without feeder and bottom vision (well, that was before I badly banged my nozzle tip holder… new is one ordered).
All comments very welcome!
For future reference and links:
