SAFETY WARNINGS AND GUIDELINES
Please read this entire manual before using this device, paying extra attention to these
safety warnings and guidelines. Please keep this manual in a safe place for future reference.
•Be careful not to damage the glass build plate.
•Take care to avoid touching hot parts, including heat blocks, nozzle, extruded
filament, and the heated build plate.
•Keep the printer and all accessories out of reach of small children.
•Do not remove or disconnect the USB cable when printing from a computer.
•Do not pull or twist the black cable harness at any time.

making repairs or performing service.
•Do not install this device on an unstable surface where it could fall and cause either
personal injury or damage to the device and/or other equipment.
•Do not subject the product to extreme force, shock, or fluctuations in temperature
or humidity.
•This device is intended for indoor use only.
•Do not expose this device to water or moisture of any kind. Do not place drinks or
other containers with moisture on or near the device. If moisture does get in or on
the device, immediately unplug it from the power outlet and allow it to fully dry
before reapplying power.
•Do not touch the device, the power cord, or any other connected cables with wet
hands.

SLICING SOFTWARE
We recommend the use of the KISSlicer slicing software to slice your models and create
the gcode print files. You can download a version of KISSlicer that is preconfigured for use
with the Delta Pro printer from the product page (30993/33346) on the monoprice.com
website.

LOADING FILAMENT
1. Place the filament spool on the holder so that the end
of the filament hangs down to the right.
2. Using a pair of scissors or diagonal cutters, cut the
end of the filament at an angle.
3. Gently straighten about 2" of the end of the filament
with your fingers, so that it is easier to feed through
the sensor and extruder.
4. Remove the filament sensor from its holder, then feed
the end of the filament through the sensor and into
the tube on the right side of the extruder.
5. Pinch the extruder idler lever and push the filament
past the gear and into the Bowden tube, just past the
pneumatic connector.
6. Turn the printer on, then preheat the nozzle to the
appropriate temperature for the material being used
(e.g., 200°C for PLA).
7. Once the nozzle is up to temperature, touch > > Load.

8
UNLOADING FILAMENT
1. Turn the printer on, then preheat the nozzle to the appropriate temperature for the
material being used (e.g., 200°C for PLA).
2. Once the nozzle is up to temperature, touch > > Unload.
3. Hold the filament sensor and carefully rotate the filament spool while the filament
is unloading to avoid tangles.
IMPORTANT: When removing the end of the filament from the sensor, carefully string it
through to hole in the spool to avoid overlapping and tangles, which WILL cause filament
jams and failed prints.
SWAPPING HOTENDS
The Delta Pro's hotend is easily swappable, so you can print with different materials at
different temperatures. While we always recommend using the default, PTFE-line hotend
for use with PLA and many other low-temperature materials, the included all-metal hotend
allows you to print with materials that require higher temperatures than what the PTFE can
handle. Perform the following steps to remove and replace the hotend.
1. Turn on the printer, then preheat the nozzle to the appropriate temperature for the
material being used (e.g., 200°C for PLA).
2. Unload the filament.
3. Cool down the hotend, then turn the printer off.

4. Remove the Bowden tube from the effector by removing the plastic pneumatic
connector clips and depressing the top of the connector while pulling the tube.
5. Disconnect the heater and thermistor connectors from the cable harness.
6. While holding the hotend, use the included 1.5mm hex wrench to loosen the two
headless hex screws on the side of the heat sink below the effector, then remove
the hotend.
7. Install the new hotend in the same orientation, then tighten the screws.
8. Reconnect the heater, thermistor, and Bowden tube, ensuring that the tube is
pushed all the way in.
PRINTING A MODEL
1. On the LCD screen, touch .
2. Use the up and down arrows on the right side of the screen to highlight the desired
gcode file, then touch .
3. Touch YES on the PRINT MODEL? dialog to begin printing.

10
AUTO LEVELING
Before you begin your first print, and anytime you remove the build plate, you should run
an auto-level to ensure that your models adhere properly to the build plate. Perform the
following steps to auto-level the printer.
1. Ensure that the hotend is at room temperature.
2. Connect the auto-level sensor to the green wire from the cable harness, then attach
the sensor's foam ring to the nozzle.
IMPORTANT: Use the minimum amount of force required to attach the sensor to the
nozzle. If the nozzle is touching the plastic membrane, it may prematurely trigger the
switch.
3. Touch > > AUTO LEVELING.
