Photonkenstein's Monsters - it's ALIVE!!!
For those who haven't been following - on a tinkering whim, I decided to try shoehorning a 70W LED array with a parallel lens setup into my Photon, since I wasn't happy with how long it was taking to print Siraya Blu (~45sec on time per 0.05 layer). *Edit* Many people are pointing out that this is excessively long. I tested twice with the Photonsters test script to find this. I'm going to test with some other resins to see if I got a bad batch of Blu.
I finally turned it on last night... and thought I'd broken it. No display on the touch panel. Taken it back apart, I thought I'd messed up the FFC. Fortunately, I had an insight this morning and realized I'd just plugged it in upside down
:D
So with that resolved, it has now completed its first print! And by print, I mean a Photonsters calibration test, since there obviously is no spreadsheet in creation that would tell me what numbers this abomination needs. For reference, it looks like I can do Blu in 14-16 second layers now instead of 45. Given that this LED array is specced as roughly 3x as powerful as the stock one, this is right on target!
While it's operational, it's nowhere near finished. There are three main problems remaining. First, I'm getting some patterning on the display from the lenses. The lens array is currently only about 10mm from the bottom of the screen. Fortunately, there's still a lot of space to work with in that direction - I could move it out another 50mm or so and still have room for the array cooling fan. That will ideally even out the array pattern.
Second, UV leakage. As seen in the last picture, my current mounting solution isn't 100% sealed, and enough light is leaking into the print chamber through gaps in the casing that, while I don't think they'd cause major problems, I would prefer to fix.
Finally, packaging. The heat sink for the array and the touch LCD currently wants to occupy some of the same space, so as a stopgap, I rerouted the FFC out the side (through the hole left by removing the left handle) and taped it to the side of the printer. While this works, it is obviously not ideal. Fortunately, I think the solution to problem #1 will also help this - by moving the entire thing up, I can reshape the mount to add clearance.
