You need a Macintosh computer with OS X 10.8 or higher running in 64 act mode. Some printer boards need a driver, like the FTDI driver, for the serial joining .

Getting the software

Go to the download page and fetch the latest adaptation for your bone. It comes either as zip code package or as pkg installer. If you have a nothing box, unzip it and drag the application on your programs folder. If you got a pkg installer, run it .

Updating the software

The software comes with an automatic updater since version 0.32. If you are not questioned for an update directly, go to the menu and run “ Help ” – > ” Check for update ” .


Configuring your printer

The following step should be, to configure your printer so you can connect your calculator with the host. Make certain your printer is connected and enabled. Some printer need limited driver to access the device, so make certain the drivers are besides installed. If you have uploaded the firmware to your printer, the driver is already installed.

Click on the “ Printer settings ” button in the toolbar. You will see a window like this :
Printer Settings - Connection Printer Settings - Connection

At the top you see a drop down box, with the presently selected printer. At the begin you have merely the default option printer. To create a new printer press the “ Add ” -button and give it a modern list. The new printer will start with the lapp settings as the last choose printer .
Below the drop down box you see four tabs with most off the data stored with the printer shape. In summation to this, for each shape a start/end/pause/kill and five drug user defines scripts are stored with shape. These can be changed in the g-code editor, which is described in a different chapter .
In this first check, you set how to connect with your printer. In “ Port ” you select the port, where your printer is connected. At the hatchway of the window, all available ports were scanned and added to the list. Select the right one. then select the baud rate entered into the firmware. Stopbits and parity are adjust for 99,9 % of the printer, so leave them unmoved .
The remove protocol determines, how the host will communicate with the printer. All supported firmwares work in ASCII mode. The Repetier-Firmware besides supports a binary format. The advantages of the binary star format are :

  • Reduced data size. Normal data is reduced to 50%.
  • Better error correction.
  • Less computation time needed for the firmware to parse the data.

You can leave this on “ Autodetect ”, which will automatically switch to binary format if Repetier-Firmware is detected. For all other firmwares, the ASCII communication is used .
The following decision is, how to send data to the firmware. The method that was planned with the foremost firmwares works like table tennis. The host send a command and waits for the firmware to return an o. This causes latencies, which can result in empty buffers if you have many humble moves. To improve rush, you can allow the horde to send more then one command at once. Your printer has a input buff. deoxyadenosine monophosphate long as you are sending not more then the size of the buff, you can send more then one instruction if they fit into the buffer. so if you disable the table tennis mode, the host will send up to “ Receive hoard size ” bytes, before it waits for the all right, telling him that the command is processed. If you are diffident on the printer buffer size choice 63, which works on all printers. Firmware compiled with Ardunio versions before 1.0 even allow 127 bytes .

The irregular pill defines important behavior you want. The Travel prey rate and Z-axis feed rate are used, when you move the extruder with the manual of arms controls. The temperatures are set in the manual controls als start values. You can change them there any time .
When you turn the extruder on, you surely want to know the temperature of it. This is done by sending the M105 command to the printer. If you don ’ deoxythymidine monophosphate design to do this yourself every ten seconds leave the option checked. You can besides select how much you want the host to check the temperature. The default option 3 seconds are a good start. With every request you get 2 entries in your log. The horde will show the read temperature at the penetrate in the condition cake, so removing these messages from the log makes it much more clear .
Park stead is where you like your extruder head the most. In the manual of arms control you have a clitoris to move the head to the park status. You can besides tell the host to go to this position, after a print is finished .
The following arrest boxes define, what the printer should do, when a print is finished .
With “ Add to comp. impression time ” you define, how the master of ceremonies should correct the calculate printing time. When the host computes the clock from g-code, it assumes all moves are executed at the feed rate requested. If you do a dense print, this will be quite correct, except that it doesn ’ t take the time to heat the extruder/bed into bill. With fast prints, the firmware needs to accelerate/decelerate a logarithm, which increases the print time. Ofter some prints, where you compared the computed and real print time, you should be able to figure out how much percentage you need to add to the calculate clock time. Don ’ triiodothyronine expect to match every print. Depending on the geometry, the time will still differ a sting .

The third yellow journalism defines your printer shape, or to be more claim the form of your human body area. The server will use this to limit your moves and to check, if your models fit onto the photographic print bed. You can besides define the position of the ten and y end stop .
The dump area is a orthogonal hole in your print layer, where you can drop filament. largely the original Mendel had this. If you don ’ t have a dump area, leave the option unchecked .

The last pill is for promote configurations, you most probably will never need. Currently it entirely contains a postprocess filter. After the slicer is done with slit, you can start an external program with the g-code. This platform must save the resulting g-code in the charge named by the # out parameter .
