220x525 Delta

I love my original Kossel Delta Printer, But I hate that it only has a small print bed. So this project is to enlarge my Kossel to the full size 220 print bed. I am using https://www.thingiverse.com/thing:154832 as part of my rebuild of my delta. Please give credit to https://www.thingiverse.com/Crashoverride for his help in designing this upgraded Delta. I used #8 3/4 Self Drilling Screws to mount the 3/4 inch Aluminum square tube to the printed ends. I just did my final Calculations on this Upgrade. This new design can print on a 225mmx844mm area or 9 1/16"x33 1/4" area. Final Print size is 230x509.5 or a max of 230x527.5. 6/5/2017: Update. I had some problems getting the Extruder base to sit level when I was doing the Dry Run process. So I've updated the RODS to 300mm from Center to Center. With that update, I was able to get a print surface of 250x475. SIDE NOTE "I'm not trying to take credit for all of the stl files, yes I have modified them to work on my design and yes you may have seen them on https://www.thingiverse.com. But I wouldn't say I have designed all of them just MOD them for this Printer." 6-12-2017: As of today, the new EX Delta is done and working. I've added springs to bed so I can adjust them. I've also added a second power supply to power the bed; it was taking way too long to heat extruder and bed at same time, so a second power supply with a 25 amp power module. I've also added the firmware I used to get this Delta working. I've also included a lower base so this Delta will be an extra 2 inches higher to accommodate the extra power supply. In conclusion, everything I tried or used is added to this delta; they all work, I just tried different variations till I liked the current final version. This final version with the 300mm rods can print on a 12 inch print bed if you want to take this version to the next level. The final print area is 220x454.7 with an extra 40mm at top.
