| − | THIS IS A WORK IN PROGRESS
| + | |
| − | | + | |
| − | ==Background==
| + | |
| − | A 3D printer takes a 3D model and turns in into a plastic part. To do this there are a number of pieces of software complete this task. A good source of more information can be found here:[http://reprap.org/wiki/RepRap_Options#Software_Toolchain Software Toolchain (reprap.org)]) We suggest the following open source applications:

| − | ==Section 1- Install software==
| + | |
| − | | + | |
| − | Gigabot is fully compatible with open source programming tools supported by the RepRap community. We encourage you to become an active participant in this thriving community!

| − | ===USB to Serial driver===
| + | |
| − | The Virtual Communications Port driver talks to your USB port in a way that Gigabot understands.
| + | |
| − | | + | |
| − | :Download and install the VCP driver for your specific operating system.

| − | :You may need administrator rights, or need to right click and "Run as Administrator".
| + | |
| − | | + | |
| − | ===Slic3r===
| + | |
| − | Slic3r takes a 3D model (usually an .stl file) and turns it into G-code. G-code is the instructions for the 3D printer to create the part. A more detailed understanding of G-code can be found [http://reprap.org/wiki/Gcode here].
| + | |
| − | :Download and install [http://slic3r.org/ Slic3r].
| + | |
| − | :Read the complete [http://manual.slic3r.org/ Slic3r manual]
| + | |
| − | :Download Slic3r settings [[File:Gigabot_Slic3r_config.ini]] to your local computer.
| + | |
| − | :Open Slic3r and go to File -> Preferences -> Mode -> Expert
| + | |
| − | :Click OK and follow prompt to restart Slic3r
| + | |
| − | :Once you have restarted Slic3r go to File -> Load Configuration
| + | |
| − | :Choose the Gigabot_Slic3r_config.ini configuration file you saved earlier
| + | |
| − | | + | |
| − | ===Printrun (Pronterface)=== | + | |
| − | | + | |
| − | This program is the interface you will use to communicate with Gigabot. Once the 3D model (.stl) has been turned into G-code, it must be feed into the printer. This can be done by loading the G-code file onto a micro SD card and inserting it into Gigabot's Viki controller or feeding it from your computer to Gigabot via Pronterface. More information on Pronterface can be found [http://reprap.org/wiki/Printrun Here]
| + | |
| − | | + | |
| − | :Download and install [http://koti.kapsi.fi/~kliment/printrun/ Printrun for Windows or Mac].
| + | |
| − | :Open Pronterface and go to Settings -> Options
| + | |
| − | :Under the Printer Settings tab change:
| + | |
| − | :Baud rate to 250000
| + | |
| − | :Bed temp for PLA to 65
| + | |
| − | :Extruder temp for PLA to 195
| + | |
| − | :X and Y manual feedrate to 6000
| + | |
| − | :Z manual feedrate to 200
| + | |
| − | :Width, Depth and Height to 600
| + | |
| − | :Click OK then restart Pronterface for the changes to take affect

| − | ==Section 2- Calibrating your Gigabot==
| + | |
| − | Correct calibration will ensure the machine moves freely and in a precise manner. Investing some time with the calibration and your prints will turn out much better.
| + | |
| − | | + | |
| − | ===Belt Tension===
| + | |
| − | Ensure the proper belt tension for the two Y axis belts and the one X axis belt. If the belts are too loose the accuracy and surface finish of your part will suffer. Belts too tight will cause accelerated wear and reduce the life of your machine. Using the belt tension clip, supplied allen wrench set and a piece of string to hang the allen wrench set on the belt.

| − | :If the belt is too loose it will look like this below:

| − | ==Just the Steps==
| + | |
| − | A video walkthrough of these steps can be found here: http://youtu.be/ZEZWn6atmq4
| + | |
| − | # '''Download and install Slic3r''' - Slic3r has a nice download and install page which can be found [http://slic3r.org/download here]. We suggest downloading the precompiled version to get started.
| + | |
| − | # '''Download and install Printrun''' - Printrun is a little more complicated to install then Slic3r. But again we recommend the precompiled version to get started. It can be found [http://koti.kapsi.fi/~kliment/printrun/ here]. Printrun doesn't need to be installed in windows. You can just run it from where ever you extract the zip file.
| + | |
| − | # '''Download Test file''' - [[File:20mm-box.stl]]
| + | |
| − | # '''Download Slic3r Configuration file''' - [[File:Gigabot_Slic3r_config.ini]]
| + | |
| − | # '''Slice Test File''' - [[File:20mm-box.gcode.txt]]
| + | |
| − | # '''Connect to printer''' - After powering up Gigabot and connecting the USB port to your computer, open Printrun, select the proper comm port, and use 250000 for the speed. Click connect.
| + | |
| − | # '''Load your file''' - Load the gcode into Pronterface. You should see a representation of the first layer of your object on the plater.
| + | |
| − | # '''Calibrate your printer''' - You will need to follow the calibration procedure at the end of the Parts Kit Assembly Instructions prior to starting your first print. Do this now if you haven't done it already.
| + | |
| − | # '''Home your axes''' - If needed, press the positive Z 1mm button on the Pronterface panel a couple of times to clear the tip from the bed surface. Watching the cables that they don't get tangled or inadvertantly touch the limit switches, press the home button to home all axes.
| + | |
| − | # '''Heat the hotend''' - Heat the nozzle to the appropriate level by typing in 200 (for PLA) in the "Heat:" area and click "Set".
| + | |
| − | # '''Watch carefully as nozzle heats''' - It is VERY IMPORTANT to see a smooth curve of heating on the graph (click the "Watch" checkbox if the graph is offline), and a positive trend on T0 in the data on the bottom left of the screen. ''If the temperature does not change within 15 seconds, immediately click "Off" on the heater and carefully check to see if the thermistor is properly seated in the nozzle tip.''
| + | |
| − | # '''Extrude some test plastic''' - With "5" in the "mm" box and "100" in the "mm/min" box, click extrude, one click at a time, until a steady stream of plastic exits the nozzle.
| + | |
| − | # '''Print your object''' - Click "Print" on Pronterface to start your print.
| + | |
| − | # '''Keep an eye on your print''' - As the Gigabot goes through it's actions, be ready to press pause if there is anything wrong with the print (and be aware that there is a buffer and will take a few seconds to actually accept the pause command). If anything sounds bad (like belts jumping or the hotend contacting the bed forcefully), power down the Gigabot using the switch on the electrical box, and the click "Disconnect" in Pronterface. Powerup again, reconnect, and assess what may have gone wrong.
| + | |
| − | # '''Retrieve your finished print''' - When the print is complete, your nozzle will cool automatically. You will need to do this manually if you paused the print for any other reason.
| + | |
| − | # '''Assess your print''' - Look at the parts of your print that could be improved. Repeat the process with slightly lower temperature... a slightly higher temperature. You can even adjust the temperature during the print to see the effects in real time. Open Slic3r and adjust other parameters one at a time to see what they do to the quality. Also, consider how the design and/or orientation of your model affects the results of your print. There are endless possibilities in not only design, but the printing process itself. Share your successes (and failures) and engage others in this expansive and growing 3D printing community!
