| - | ====== Tips & Tricks ====== | ||
| - | |||
| - | ===== General ===== | ||
| - | Here you will find information about general issues concerning the operation of the RepRap Industrial in your specific work environment. | ||
| - | |||
| - | ==== Commandline Access to the linux operating system via SSH ==== | ||
| - | Use SSH on your computer connected to the same LAN as your 3D printer to log in to the RepRap Industrials' built-in BeagleBone Black. You can use the hostname from the printers' [[reprap-industrial-v1:manual#Setup|Backend-URL]] and log in with the following access data: | ||
| - | User: kiosk | ||
| - | Password: eight-digit combination from the serial number at the back of the device. Take the first two four-digit blocks - XX-AAAA-BBBB-CCCC-YYYY becomes an "AAAABBBB" password. | ||
| - | |||
| - | ==== Setting a static IP address for RepRap Industrial ethernet connection ==== | ||
| - | First, [[#Commandline Access to the linux operating system via SSH|establish a commandline connection]] to the printer. | ||
| - | |||
| - | From within the terminal session, edit the network configuration via the command line editor "nano" | ||
| - | sudo nano /etc/network/interfaces | ||
| - | (use the same password as for the SSH connection) | ||
| - | |||
| - | The current DHCP setup looks like: | ||
| - | # The primary network interface | ||
| - | auto eth0 | ||
| - | iface eth0 inet dhcp | ||
| - | pre-up iptables-restore </etc/iptables.rules | ||
| - | |||
| - | Change the setup according to your needs. | ||
| - | Example: | ||
| - | # The primary network interface | ||
| - | auto eth0 | ||
| - | iface eth0 inet static | ||
| - | address 192.168.1.20 | ||
| - | netmask 255.255.2555.0 | ||
| - | network 192.468.1.0 | ||
| - | broadcast 192.168.1.255 | ||
| - | gateway 192.168.1.254 | ||
| - | dns-search family.local | ||
| - | dns-nameservers 192.168.1.254 | ||
| - | pre-up iptables-restore </etc/iptables.rules | ||
| - | |||
| - | The rest of the file remains unchanged. Save the file using CTRL+X and confirm the overwrite query with "Y". | ||
| - | Disconnect and finish by typing | ||
| - | exit | ||
| - | |||
| - | Shut down (see [[reprap-industrial-v1:Manual#Manual control]]) and reboot (power-on button, [[reprap-industrial-v1:Manual#Electronic chamber|11]] in [[reprap-industrial-v1:Manual#Electronic chamber|fig. 4]]) the RepRap Industrial to establish the alterations. | ||
| - | <WRAP clear> </WRAP> | ||
| - | |||
| - | ==== Use a custom NTP server for time signals ==== | ||
| - | First, [[#Commandline Access to the linux operating system via SSH|establish a commandline connection]] to the printer. | ||
| - | |||
| - | From within the terminal session, stop the NTP daemon background process | ||
| - | sudo service ntp stop | ||
| - | (use the same password as for the SSH connection) | ||
| - | | ||
| - | Edit the NTP daemon configuration via the command line editor "nano" | ||
| - | sudo nano /etc/ntp.conf | ||
| - | | ||
| - | Search for the few lines beginning with <code>server ...</code> and add an additional new line **before** these **with the address to your local NTP server** like this | ||
| - | server 192.168.1.123 | ||
| - | | ||
| - | add another additional statement anywhere in this file | ||
| - | # ignore panic threshold for huge time differences | ||
| - | tinker panic 0 | ||
| - | | ||
| - | The rest of the file remains unchanged. Save the file using CTRL+X and confirm the overwrite query with "Y". | ||
| - | | ||
| - | Re-enable NTP client service for background operation | ||
| - | sudo service ntp start | ||
| - | |||
| - | Disconnect and finish by typing | ||
| - | exit | ||
| - | |||
| - | Shut down (see [[reprap-industrial-v1:Manual#Manual control]]) and reboot (power-on button, [[reprap-industrial-v1:Manual#Electronic chamber|11]] in [[reprap-industrial-v1:Manual#Electronic chamber|fig. 4]]) the RepRap Industrial to establish the alterations. | ||
| - | <WRAP clear> </WRAP> | ||
| - | |||
| - | ==== Changing Shell Password in the BeagleBone Black Operating System ==== | ||
| - | |||
| - | After manually creating a new Micro-SD Card from a pre-packaged upgrade release provided by //Kühling&Kühling//, the user account running the RepRapOnRails software in the Linux operating system will be in default configuration. To change the password, use SSH on your computer connected to the same LAN as your 3D printer to log in to the BeagleBone Black. You can use the hostname in the printers' [[reprap-industrial-v1:manual#Setup|Backend-URL]] as its address and log in with the following access data: | ||
| - | |||
| - | User: kiosk | ||
| - | Password: kiosk | ||
| - | | ||
| - | Now you can set a new password by entering | ||
| - | |||
| - | passwd | ||
| - | |||
| - | and following the instructions. In delivery condition the unique password is an eight-digit combination from the serial number at the back of the device. Take the first two four-digit blocks (example: XX-AAAA-BBBB-CCCC-YYYY becomes an "AAAABBBB" password). | ||
| - | |||
| - | |||
| - | ===== Slicing ===== | ||
| - | Any information we gather related to improving or easing the slicing process is listed in the following paragraphs. | ||
| - | |||
| - | ==== Profile display problems in Slic3r for Windows ==== | ||
| - | ---- | ||
| - | **This bug will be fixed with the upcoming release of SLic3r v1.2.x.** | ||
| - | ---- | ||
| - | <WRAP group> | ||
| - | <WRAP half column> | ||
| - | It is a known problem that in Slic3r for Windows the drop-down lists for the profile selection are too narrow to display the full profile name. This can make it impossible to choose the correct profile when processing your slicing settings for creating a G-code.\\ | ||
| - | </WRAP> | ||

| - | |||
| - | ==== Overhang - adjusting the layer thickness ==== | ||
| - | If you want to print filigree objects with overhanging structures without adding supports, try reducing the layer thickness for this print by 15 - 20%. This will result in a finer Z-axis resolution and increased overlay of subsequent layers so that more stability is gained over the height of the target object. | ||
| - | |||
| - | |||
| - | ==== Modifying infill and perimeters ==== | ||
| - | There are currently two Slic3r profiles available at our [[https://github.com/kuehlingkuehling/RepRap-Industrial-Slic3r-profiles|GitHub repository]] that provide preset ready-to-print slicing settings. Her are some tips for handling these profiles to adjust them to your needs.\\ | ||
| - | The //SOLID// profile normally needs no modification since it comes with stable, reliable settings for printing solid objects with 100 % infill.\\ | ||
| - | The //ECO// profile supplies settings for objects with loosened infill. This makes objects lighter and reduces the print time and the material consumption. To achieve good results, the settings may have to be adjusted.\\ | ||
| - | We recommend to set the following always for printing ECO objects: | ||
| - | * A hull thickness of 1.0 to 1.5 mm. As a rule of thumb divide the hull thickness by the nozzle tip diameter and set the amount of perimeters equal to the result. Such, a closed, smooth and stable hull is ensured. | ||
| - | * Honeycomb infill as it provides highest stability at optimal density. | ||
| - | * A minimum infill of 15 %. | ||
| - | * A maximum infill of 30 %. Increasing the infill further does not have a significant advantage compared to a solid body but strongly increases the printing time. | ||
| - | |||
| - | |||
| - | |||
| - | ===== Operation ===== | ||
| - | In the following you will find more detailed descriptions of functions of the RepRap Industrial. In most cases, these are topics upraised by support requests or in-house lab experiments. | ||
| - | |||
| - | |||
| - | ==== Calibrating the extrusion ==== | ||
| - | The stability and dimensional accuracy of any printed object require a correct amount of filament conveyed through the nozzle. Too little extrusion and the part will be thin-walled, fragile and likely to break. Too much material is likely to clog the nozzle and ruin the print. | ||
| - | The amount of material effectively conveyed through the nozzle is depending on: | ||
| - | * the 3D printer itself - slight variations are possible due to the manufacturing process; | ||
| - | * the actual filament diameter - in the range of the dimensional stability of the filament; | ||
| - | * the printed material's properties - the extruder drive wheel grinds deeper into softer materials, thus reducing the actual diameter; | ||
| - | * the idler tension - high tension will cause the drive wheels teeth to grind deeply into the filament, causing a dilation of the material and a reduced output.\\ | ||
| - | \\ | ||
| - | To make sure that the print result is stable and accurate, an //extrusion multiplier// must be found for every material on every apparatus; it may be that this factor must be found for every spool of filament.\\ | ||
| - | The correct extrusion multiplier is set in the slicing software, compensating for the above named variables.\\ | ||
| - | <WRAP group> | ||
| - | <WRAP half column> | ||
| - | To find the correct multiplier, open the //Setup// menu at the GUI and choose [Calibrate Extrusion].\\ \\ | ||
| - | A detailed description for ABS filament can be found [[reprap-industrial-v1:software-version-v1.1.0-operation-and-commissioning#extruder-calibration|here]].\\ | ||
| - | For other materials, the same procedure applies but you have to prepare a G-code for the test print. | ||

| - | ==== Deactivating the heating elements after end of print job ==== | ||
| - | Sometimes you may want to start a print job just before finishing time or the weekend. Since there is currently no automatic shutdown function, the 3D printer will then stay on all night respectively some days. With the following description you can alter the End G-code of your print so that the heating elements are shut off after the print job has been finished so that the power consumption is reduced significantly. A side effect is, that due to the fact that the build chamber needs some hours to channel off the heat the cooling process is slowed and thereby internal tensions of the printed object are reduced. | ||
| - | To deactivate the heating elements after a print job: | ||
| - | <WRAP group> | ||
| - | <WRAP half column> | ||
| - | * Open the [Printer Settings] tab in Slic3r and choose the //Custom G-code// menu. | ||
| - | * Activate the End G-code editor by clicking into the text field. | ||
| - | * Position the cursor in the last line before the ''; /END-GCODE'' entry. | ||
| - | * Enter the command\\ ''M104 S0 T2''\\ This will set the heating elements of the build chamber to a temperature of 0 °C. | ||
| - | * Enter the command\\ ''M140 S0''\\ This will deactivate the print bed as the last action of the current G-code. | ||
| - | </WRAP> | ||

| - | </WRAP> | ||
| - | </WRAP> | ||
| - | |||
| - | ==== Adjusting the build chamber temperature ==== | ||
| - | <WRAP note> | ||
| - | NOTICE | ||
| - | |||
| - | //The build chamber temperature is preset to the maximal permissible temperature of +70 °C at delivery.\\ Exceeding +70 °C will damage interior components of the RepRap Industrial such as stepper motors, bearings and electronics.// | ||
| - | </WRAP> | ||
| - | |||
| - | <WRAP group> | ||
| - | <WRAP half column> | ||
| - | Since hitherto the RepRap Industrial is the only commercially available Open Source 3D printer with an actively heated build chamber, common slicing software does not feature ambient temperature settings. For some materials, it is advantageous to modify the chamber temperature together with the other temperature settings. | ||
| - | The build chamber's temperature of the RepRap Industrial is set via the "Start G-code" which can be manually altered. | ||
| - | |||
| - | To change the build chamber temperature (in the following example we use our standard //Slic3r// - other | ||
| - | software may differ in denotations): | ||
| - | - Open your slicing software. | ||
| - | - Open the tab "Printer Settings" and choose "Custom G-code". | ||
| - | -- Go to the line reading:\\ <code> M104 S70 T2; set recirculating air heater to 70 degree celcius target temperature</code> | ||
| - | - Change the entry "S//xy//" (here //S70//) by replacing the value //xy// with the desired temperature, for example //50° C//:\\ <code>M104 S50 T2; set recirculating air heater to 50 degree celcius target temperature</code> (for logical reasons, the comment should be aligned) | ||
| - | - If you want to keep the settings, save them in the profile (see [[http://manual.slic3r.org/|Slic3r manual]]). | ||
| - | Any G-code exported with this profile loaded will heat the build chamber to the stated temperature prior to printing. | ||
