AM8 Large Print Volume 220x320x290 (Enlarged Bed)

thingiverse

The links below for the 200x300 bed are now unavailable, I've found replacements at Gulfcoast Robotics https://gulfcoast-robotics.com This is a straightforward way to expand your print volume if you already have the AM8 built. This will increase your Y-Axis to 300mm and Z-Axis up to 300mm depending on your hotend and carriage design. There are only two parts to print and a few parts to purchase. You will need to buy longer Y-Axis rods, longer Z-Axis extrusion, larger sub plate (H-Plate), larger bed heater and larger bed. Here's the list of parts I purchased. You will need to print four bearing block spacers and one Y-Axis belt holder. https://www.amazon.com/gp/product/B0045DWA9C/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 https://gulfcoast-robotics.com/products/300x200mm-aluminum-heated-bed-build-plate-for-reprap-3d-printer-prusa-i3-full-kit https://gulfcoast-robotics.com/products/anodized-aluminum-y-carriage-plate-xl-300x200-for-upgrade-reprap-3d-printer-prusa-i3 https://gulfcoast-robotics.com/products/y-carriage-plate-xl-300x200-kit-with-4-x-sc8uu-for-reprap-3d-printer-prusa-i3-upgrade 2040x480mm extrusion 2 pieces https://us.misumi-ec.com/vona2/detail/110302684350/?Inch=0 https://www.amazon.com/gp/product/B00UR0N370/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B00F2IQNX8/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 To accomplish this, you will need to remove the existing 440mm Z-Axis extrusions and install them in place of the existing Y-Axis 340mm extrusion. Then add the 2 new 480mm extrusions to the Z-Axis. Add the 2 new 495mm 8mm rods to the Y-Axis. Install the new subplate, heater and bed. I would not use the wire that comes with the bed as it gets too hot; replace it with good quality silicon wire at least 14ga. Don't forget you will have to change your bed size in your slicer software and in Skynet/Marlin config file. NOTE: To get the most amount of Z-Axis travel, you will also need to do the 2020 X=Axis conversion and use two short bearing mounts.
