This is a printable mount for attaching a stock Makerbot PLA Active Cooling Fan Blower (Turbo Fan) to the Makerbot Replicator 2X. This is a “Plug and Play” upgrade and takes about 30 minutes to complete with all parts onsite. Despite the pictured upgrades made to my printer, you do not need them for this to work. This part was designed to be functionally as close as possible to the stock Makerbot part originally intended for the Makerbot Replicator 2. Please note that using PLA in a Makerbot Replicator 2X will void any factory (6 month - 1 year) warranty.
In order to activate the code that turns on the fan during printing in Makerbot desktop, change the material setting from ABS to PLA. If you face clogging issues with PLA in the 2X, use vegetable oil to lubricate the filament. I would suggest printing an filament oiler/sponge holder. Note: Be sure to use ONLY vegetable oil as its temperature of spontaneity (combustion temp.) exceeds 400F, where as other oils combust at temperatures below 230F. Using oils other than pure vegetable oil will cause black “gunk” to build up in your extruder nozzle and thermal barrier tube, thus preventing filament extrusion, or causing a fire to occur.
In order to upgrade your Makerbot Replicator 2X with a Makerbot Replicator 2 PLA Active Cooling Fan, follow these steps:
- Call Makerbot and order a “Replacement Active Cooling Nozzle” (~$10.00), a “Replacement PLA Active Cooling Fan Blower (Turbo Fan) (~$25.80)” and the two screws that connect the “PLA Active Cooling Fan Blower (Turbo Fan)” to the “Active Cooling Mount”.
-a. Makerbot will most likely forget to send you the bolts that you need with the fan parts, so I would suggest ordering them from a more reliable retailer, such as McMaster-Carr, as they are standard parts, unlike the custom fan ducts listed above.
-b. Bolt Information: 6-32, 25mm (.985”) long threads, Philips head 6.56mm (.26”) dia
- Print the PLA Active Cooling Mount that I have designed.
- Unscrew the left-side fan and heat sink assembly.
- Place the printed mount in place of the stock, black, cylinder spacers.
- Attach the “Replacement PLA Active Cooling Fan Blower (Turbo Fan)” from Makerbot” with the bolts that you ordered, either from Makerbot or another retailer.
- Gently slide the “Active Cooling Nozzle” into the bottom (Heated build plate side) of the “Replacement PLA Active Cooling Fan Blower (Turbo Fan)”.
- Flip the printer over. Remove the Mighty Board (Motherboard) cover.
- Plug the wire from the “Replacement PLA Active Cooling Fan Blower (Turbo Fan)” into the last remaining open slot on the Makerbot Mighty Board.
- Reinstall the Mighty Board (Motherboard) cover and turn the printer upright.
- Tuck the “Replacement PLA Active Cooling Fan Blower (Turbo Fan)” wire into the black mesh sleeve starting at the Mighty Board and working towards the fan so as to leave as much slack as possible next to the extruder head to allow for easy movement without stretching the wire.
- You must adjust your slicing software by plugging in the printer via usb. Failure to do so will cause the extruder head (newly installed fan), to impact the side of the printer.
-a. Makerbot Desktop
--i. Plug in printer via USB cable.
--ii. Adjust X offset +/- 30mm or settings of the like so that when it starts up the head will not travel so far to the left.
---1. I suggest playing with the settings before installing the fan to confirm that you are adjusting the correct setting. You will know that it is the correct setting as you can visually observe the extruder carriage moving farther or closer to the edge of the printer on the steel rods.
-b. Simplify 3D
--i. “Edit process settings”>”scripts”>
--ii. Mxx _____; MOVE TO WAIT POSITION OFF TABLE
---1. ^THIS IS THE LINE THAT WAS CAUSING THE ERROR.^
--iii. Adjust the x from -130 to -90, x to the right (from the front) is positive (numbers represent mm).
Note: Downloadable print file is set for the right extruder head, PLA.
