FT6, Entire Printer & Bed Upgrade & Gantry/Carriage, 3rd leadscrew

thingiverse

Hi, This is the entire printer, plus a redesigned bed with a 3rd leadscrew and gantry mounts and carriage. The original bed heater can be carefully peeled off, cleaned with acetone and rags and plastic putty knife, and reapplied with high temp HVAC Red RTV, and you have to roll the bubbles out. I have not installed the new gantry and carriage mounts yet. This printer is running an SKR PRO, TMC 5160's, Klipper, BLTouch, Octoprint, 24V and separate 5V PSU's, with a relay module to control the Bed AC power and the 24V PSU. I have been running Marlin 2.0 as well. The bed is made from 3/16 aluminum and the bed surface was smooth from the supplier so I have 6in wide Kapton tape as the bed surface. The bed is within 0.4mm for the entire bed level, so very flat. I leveled it by changing the washers under the heated portion. Heat transfer from the heated portion is very minimal to the vertical supports. My current printable area is 740x340 and 410 high, but these should bump up once the new gantry/carriage is installed, which were inspired by blinkingsuns. I used a single 2000mm belt to tie all the Z leadscrews together: https://www.aliexpress.com/item/4000307119139.html?spm=a2g0s.9042311.0.0.27424c4dxR4p5p Here is the 3rd leadscrew: https://www.aliexpress.com/item/32840731929.html?spm=a2g0s.9042311.0.0.27424c4dxR4p5p I will add more descriptions later, but for now I am just posting so others can use this if needed. Thanks!
