Congratulations on receiving your Delta Go Desktop 3D Printer!

Before you begin unboxing your printer, please read the following instructions below. Failure to follow instructions could result in damage to your printer. If you’re stuck on anything or have questions, feel free to ask our community in the forums or contact us. We’re always here to help and our response time is usually within 24hrs.

WARNING: The Delta Go 3D Printer generates high temperatures and includes moving parts that can cause injury. Never reach inside your 3D Printer while it is in operation. Always allow the 3D Printer to cool down before reaching inside.

WARNING: Do not leave your 3D Printer unattended while it is printing, especially around young children or pets.

CAUTION: In case of emergency disconnect power supply from wall socket.

CAUTION: The socket outlet must be located near the equipment and must be easily accessible.

FIRE HAZARD: The Delta Go has an automatic safety shutoff, which will halt the printer and turn off the heater if it takes more than 60 seconds for the heater to reach the target temperature. This prevents the heater from continuously increasing the temperature if the thermistor is not in contact with the heater.

Make sure the thermistor does not fall out of the hotend’s nozzle. If it does, the printer will think that the hotend is cold and proceed to keep increasing the temperature, which could lead to a runaway hotend. To make sure it does not fall out, always keep the red sleeve on the hotend’s heater so it holds the thermistor inside and do not pull on the thermistor wires that go into the nozzle.

Addiction: You may become addicted to 3D printing. Currently there is no cure. Deltaprintr takes no responsibility for this 🙂

Step 1

As you unbox your printer, please check to make sure that everything arrived with your printer.

1 x Delta Go 3D Printer
1 x Sample of 1.75mm PLA
1 x USB cable
1 x 4GB Class 6 MicroSD Card with adapter (the MicroSD will already be inserted on the side of the printer)
1 x Power supply
1 x Extra blue tape

Step 2

Now that your printer is set up, we’ll go ahead and install the Cura 1 software. This is the software you will use to prepare your 3D models for printing. Download the version for your operating system and follow the screenshots below to install the software.

All Windows users: You must download this required USB driver, right click on it and “Run as Administrator” to install the INF file. It should create a new COM port that you can then use to connect to the printer.

Windows 8 users: If you are having trouble installing the driver, please try these steps.

Tip: Take a moment to disable the “sleep” settings on your computer. This will help you to avoid frustration later on. If your computer goes to sleep while printing via USB connection, the print will halt and fail.

Step 3

Next we are going to set up the Delta Go 3D Printer in Cura. Follow the screenshots to the right to set up the printer.

Make sure that your machine settings match the ones listed in the last screenshot.

Step 4

After completing the Configuration Wizard, the Cura control panel will open. Enable the Pronterface User Interface (UI).

Step 5

The first time that you open Cura, you will see the Ultimaker Robot on the print panel. Remove this model by right clicking on the robot and select “Delete object”.

Step 6

Download the Delta Go Cura profile and unzip it (if it’s not already compressed). Then go to File > Open Profile and select the file you just downloaded called Delta_Go_Cura_Profile.ini from your downloads folder.

Tip: You can verify that the new settings loaded by checking your print speed and temperature settings. It should read 30 mm/sec and 200 C as shown in the last screenshot.

Step 7

Download the 20mm_cube.stl file and load it into Cura by clicking the “load model” icon.

Step 8

After shipping your printer, we need to re-run the auto-calibration setup to ensure prints stick to the bed.

Un-plug your printer from the power supply and USB. Pull off the sample print and peel off the blue tape from the bed of the printer so the aluminum bed is exposed. Slowly move your carriages down until your hotend’s tip touches the aluminum bed.

Go ahead and connect your Delta Go 3D printer’s power supply and USB cable to your computer. Click the print icon and the pronterface window that we enabled before will pop up (Windows 10 users: if you’re having issues connecting, try download Arduino, which will install the necessary drivers). Do NOT click print yet on the pronterface window! On the command input line on the bottom right of the window, type M119. Commands are case sensitive and letters are always capitalized.

If you see this output: max_x:0 max_y:0 max_z:0  Probe: 0 It means that your printer’s hotend cannot make contact with the bed. This is because there is probably left over plastic on the tip of the nozzle after we tested the Delta Go 3D printer at our factory. You’ll need to move the hotend off the bed a few inches and heat it up to 200C (you may need to click the up & down arrows next to the temperature input field for the change to take effect). You’ll notice how the lights change from blue to red slowly. Once the lights dim red in and out, it means the target temperature has been reached.

Clean the nozzle with a paper towel/tweezers. DO NOT try to remove the plastic using pliers or any tool that can damage your nozzle. Heat it up and use tweezers/paper towel. You only need to clean the bottom surface of the nozzle. Be careful to not get burned!

After you cleaned the nozzle, turn off the hotend’s heater by changing the temperature to 0 degrees and move it back down and send M119 command again. Does your output show Probe: 1 ? If the number changed from 0 to 1, it means the nozzle is able to make contact with the bed. Awesome!

Copy and paste this command: M32 auto_calibration.gcode and click enter to begin the auto calibration process. The hotend will proceed to tap the bed several times and will take about five minutes to complete. Wait until the lights on your printer turn green before moving on (the printer may be idle for a few minutes). Do not touch your printer while this process is happening or your calibration may be thrown off.

The hotend has to tap at the corners of each tower in addition to the center. If it only taps the center and the lights turn green, re-run the calibration process.

Tip: You only need to auto-calibrate after you transport your printer or do maintenance on your hotend. Auto-calibration is done to make sure the first layer sticks to the bed. The auto-calibration results are saved on the printer’s MicroSD card in the config-override file so you do not have to re-run it before every print.

You can also install the standalone pronterface (aka Printrun) version. You can download it from our support page. The standalone version offers more options than the version incorporated into Cura. You can use this for manual control of your 3D printer and Cura for slicing and preparing the model for printing.

Step 9

After your auto-calibration finished and the lights turned green, re-plug the power to your printer to restart it. Heat up your hotend to 200 Celsius by typing in 199 into the Pronterface temperature setting and clicking the up arrow key to change it from 199 to 200. When you click the up arrow key, it will activate the heater on the hotend to reach the desired temperature. The hotend should heat up in under a minute and your lights will change from blue to red.

Next, take the sample of filament that came with your printer and cut the end at a sharp angle so as to make loading the filament easier. Push down on the extruder lever with one hand (just a bit to release tension, not all the way down) and insert the end of the filament from the left side of the extruder (into the small hole) using the other hand. Push the orange filament all the way up through the tube and into the hotend until you see plastic coming out the nozzle. You may see a different color coming out at first since we test your printer at our factory before shipping it. Once you see filament start to ooze out the nozzle, use the Cura software commands to push the rest of the filament as shown in the screenshot on the right until you see orange filament start to come out.

Tip: If you’re having difficulties pushing the filament through the extruder and into the tube, try fiddling with the extruder lever a bit. You can also try cutting the tip of the filament from both sides so that it’s in the shape of a cone rather than a right triangle. The sharper the tip of the filament, the easier it will be to load it into the tube.

Also, make sure you do not simply put the orange PLA sample that came with your printer on the table. You need to hang it on a bar or some sort of roller setup so that it easily feeds into the aluminum extruder on the side of the printer. Otherwise if you simply lay it down on the table, it can get tangled and cause a jam.

Step 10

Now we’re going to go ahead and start your first print! Exciting!!

Tape the circular blue tape onto the bed (included with your printer) as shown in the picture on the right. Make sure the tape has no air bubbles under it and that the perimeter of the tape is flat so it doesn’t peel off.

After adhering the tape to the aluminum bed, use a paper towel and pour just a tiny bit of alcohol on it and wipe the blue tape with it. DO NOT pour alcohol onto the printer! Using alcohol will remove any oil or contaminants from touching the tape with your fingers to ensure that plastic parts stick to the bed and don’t warp. We recommend you use Isopropyl Alcohol that is stated for at least 90%.

Then click print. The printer will first home and may be idle for a few minutes while it reaches the correct temperature. Once the temperature target has reached, the hotend will then proceed to move down to the bed and start to print.

Congratulations, you’ve now successfully completed your first print!

Tip: Do not try to print without blue painter’s tape. The plastic will not stick to the aluminum bed. It will only stick to blue painter’s tape. Never use spray, glue or any other adhesives on the printer’s bed to prevent the plastic from warping. Your printer’s aluminum bed must stay clean at all times in case you need to auto-calibrate again in the future. If you use glue or spray it with adhesives, you risk preventing the hotend from making contact with the bed to auto-calibrate.

Important Information!

Unmount SD Card – When copying files to the Micro SD card using the included adapter, always be sure to eject the card before removing it from your computer. Otherwise you risk the possibility of corrupting your MicroSD card or the files on it, which may cause your printer to malfunction.

The MicroSD card must be inserted into the Delta Go when using it, as it contains the firmware and settings for the printer.

Printing speed vs. temperature – In order to get good printing results, remember that printing speed and temperature are interdependent. If you increase the speed, temperature must also be increased and vise versa. There are however limits for both. We have included the table below as a guide for when you print with PLA filament. Note that this is an approximation and minor adjustments may need to be made depending on your filament material, quality and supplier. We do not recommend printing faster than 60mm/sec until you have used your printer for at least a month to get familiar with it. Printing higher than 60mm/sec will result in poor quality prints and may jam your hotend.

Speed (mm/sec) Temperature (Celsius)
30 190-210
40 210-220
60 220-225

Blue painters tape
– We highly recommend you use our custom blue painters tape. We’ve custom engineered this tape to work with our 3D printers. Warped parts can cause print failures as explained in our print troubleshooting guide.

Also make sure that when you lay down the tape on the Delta Go’s bed that there are no bubbles under the tape. If you use cheap blue painter’s tape this will happen and cause the first layer to not print flat and possibly start peeling off the bed. You can re-use the blue tape for multiple prints, just make sure to lightly press it back down on the bed again after you pull off a print (since the force of pulling off a print will also pull the tape up) and wipe it with alcohol again in preparation for a new print.

Printing from SD Card
– You can also print from the SD card (rather than using USB cable) by saving the prints onto it. This is our preferred method as printing from a computer can sometimes be risky! What if your computer falls asleep or crashes? The print will fail! Or you may also want to move your laptop away from the printer eventually. Printing from SD card is handy when you’re doing long prints. There are two ways to do this:

a) Save the file onto the SD card inside the ‘Prints’ folder. We recommend saving it in this folder to keep it separate from the main config files so you don’t accidentally overwrite them or delete them. Then you can open up Pronterface and type in the command input field @play /sd/Prints/FILENAME.gcode where FILENAME is the name of your gcode file. Note that upper/lower case is sensitive. Wait until the first layer starts printing before un-mounting the MicroSD card and disconnecting the USB cable from the printer. If you disconnect before it starts printing, you may cause the printer to stop working and will have to restart the print.

b) There is a shorter way to do it also. You can save the file in the root folder of your SD card (not in the Prints folder, outside of it) and name it on_boot.gcode. Now whenever you plug in the power supply to your printer and power it up, the print will automatically start. Make sure you’re ready for it to start before you power up!
