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.

9
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.

11
4. Once the process is complete, remove the auto-level sensor.
ADJUSTING THE Z-OFFSET
The Z-offset is the distance between the glass build plate and the nozzle. The auto-level
process ensures that this distance is consistent across the build plate, but the distance
itself must be manually calibrated. You can easily do this using a piece of clean, flat
copy/printer paper, which is usually about 100 microns thick. Perform the following steps
to adjust the Z-offset.
1. Touch > .
2. Place a piece of copy/printer paper on the build plate.
3. Touch in the middle of the screen.
4. Touch or to adjust the height of the nozzle up or down.

12
5. Adjust the height of the nozzle until it pinches the paper, checking each time
whether the paper can be moved or not. Once the paper cannot be moved, return
to the main menu and touch to home the printer.
CLEANING THE BUILD PLATE
To prepare the build plate for printing, first ensure that the build plate is at room
temperature, then use rubbing alcohol or another ammonia-free solvent and a soft, lint-
free cloth to remove any dust and oil from the surface.
CALIBRATING THE PRINTER
Your Delta Pro 3D printer was calibrated at the factory to ensure great prints out of the
box. However, sometimes it may be necessary to recalibrate certain functions over the
natural course of use.
Calibrating Dimensional Accuracy
If you find that the dimensions of your prints differ from the dimensions of your CAD
model beyond 10 microns or so, you may want to the adjust the firmware to correct the
discrepancy. Perform the following steps to calibrate the dimensional accuracy.
1. Go to the Delta Pro page (30993/33346) on the monoprice.com website and
download the Sample Prints for Calibration package.
2. Print the calibration box gcode file.
3. Carefully measure the printed model with calipers, aligning the jaws with the layer
lines and record the dimensions.
4. Touch > Structure. Note the Push Rod Length. Calculate a new Push Rod Length
using the following formula:
New Value = Old Value x (Measured Printed Dimension / 3D Model Dimension)

13
5. Touch Push Rod Length, erase the old value, then enter the new value.
PID Tuning
If you find that the nozzle fails to maintain a stable temperature or fails to reach the target
temperature, you can run the auto-PID tuning procedure to attempt to correct the issue. If
nozzle temperature issues persist after running the auto-PID tune, you may need to replace
the thermistor or heater. Perform the following steps to run an auto-PID tune.
1. The tuning process varies slightly depending on the nozzle hotend type and the
target temperature of the material you are using. For the PTFE-lined nozzle, turn the
part cooling fans (side fans) to 100% power before proceeding to tune the PID.
Leave the fans off for the all-metal nozzle and materials with target temperatures
higher than 260°C. To control the fans, touch >. Set the fans to 100%
(default) or 0%, then touch .

14
2. Touch > Temperature > Hotend 1 Settings > PID Settings > Auto PID Tuning.
Wait for the process to complete.

15
PREFERENCES
Changing the LCD Screen Color
To change the LCD screen color, touch > System > .
1 Tap Preheat Temperature
You can change the default 1 Tap preheat target temperature by touching >
Temperature > Preheat Setting > 1 Tap Preheat, then enter the desired target temperature
value.

16
Maximum Temperatures
By default, the maximum temperatures allowed by the firmware are set to the maximum
safe operating temperature of the PTFE-lined hotend, which is 260°C. If you want to
increase this while using the all-metal hotend, touch > Temperature > Hotend 1 Setting
> Max Temperature and enter a value at least 5°C higher than the desired target
temperature to allow the PID to function properly.

17
UPDATING THE FIRMWARE
In the event that the printer's firmware has been updated, it will be linked on the product
page (30993/33346) on the monoprice.com website. You should download and install the
latest firmware. Perform the following steps to update the firmware.
1. Download the zip file containing the updated firmware files, then extract the files
to a USB flash drive.
2. Touch > System > .
3. Select the folder containing the .bin firmware file, then touch Update.
4. Touch > System > .
5. Select the folder containing the .ui user interface file, then touch Update.

18
CARE AND MAINTENANCE
Regular care and maintenance will keep your Delta Pro 3D printer looking and operating
like new for years. The following procedures should be performed periodically.
•Clean the printer's frame with a damp, lint-free cloth, such as a microfiber cloth.
•Clean the glass build play with rubbing alcohol or another ammonia-free solvent
and a soft, lint-free cloth.
•Lubricate the magnetic control arms with PTFE or lithium grease on at least a
monthly basis. This can be done by applying a small amount of grease onto the
magnet of the control arms, which function as a lubricant reservoir. After a few
prints, wipe away any excess grease from the ball joint using a lint-free cloth.
•The carriages have been factory calibrated to ensure many thousands of hours of
consistent, precision movement. If after an extended period of time they seem
noisy, lubricate the wheels using silicone lubrication ONLY.
•Use a dry brush to clean the extruder gear's teeth when they become clogged or
when the gear starts to slip.
•Clean the LCD touchscreen display with the printer powered off using a soft cloth.
DO NOT use any solvents or cleaning fluids on the display.
