If you are planning on printing high temp materials, it is recommended you print the parts in ABS.</p><p>&nbsp;</p><p>Parts should be printed without supports with two exceptions:</p><ol><li>The main body “Hotend Shroud” requires supports for the cable channel. I recommend using custom supports for that area ONLY.</li><li>The left part-cooling vent WITH ABL mounting is printed “upside down” for best result. Supports from buildplate ONLY, and make sure to block supports that go in to the vent.</li></ol><p>&nbsp;</p><h4>Preparation:</h4><p>&nbsp;</p><ol><li>Remove the lower V-roller from the Head assembly</li><li>Remove the head assembly from the printer</li><li>Optional: Crate connectors for the Heat cartridge/thermistor/fans and Blowers (HIGHLY recommended)</li><li>Remove the stock shroud and disassemble the fan and blower</li><li>Splice the part-cooling fan wires to allow for a second 4010 blower&nbsp;</li><li>push the blowers in to the part cooling ducts. they should fit snugly.
