## Ensure 15 minutes have passed before beginning the next step. The dispenser should not be cold to the touch.

## Ensure 15 minutes have passed before beginning the next step. This helps the ink flow easier, so the dispenser should not be cold to the touch.

## '''Read carefully.''' The Voltera application explains this step well. Follow the on-screen instructions before moving on to the next step. Some tips/tricks/warnings: <br /><br /> - '''Nozzles are fragile!''' You would be surprised how easy it is to break one. Treat this process with care!<br /> - Hold the dispenser over a paper towel to prevent ink from getting everywhere.<br /> - If you need to wipe the nozzle, do so '''gently''' and '''use a cotton swab found in the drawers.''' <br /> - Ink should not be flowing quickly out of the dispenser when you finish priming, but '''a very small amount''' of flow is OK. <br /><br /> [[File:Voltera priming.jpg|border|none|300x300px]] <br />

## Click "Advanced." Start with the '''Z at 0.10 mm''' and the '''E at 0 um'''. Adjust the Voltera to these values.

## Click "Advanced." Start with the '''Z at 0.10 mm''' and the '''E at 0 um'''. Adjust the Voltera to these values, as it is a safe distance for the dispenser.

## Click "Calibrate."

## Click "Calibrate." The Voltera will lay down a test print. Pay close attention to the amount and consistency of the ink.[[File:Voltera calibrate.jpg|border|none|300x300px]]

## The example below has slightly too much ink. Notice how a portion of the horizontal lines touch and some parts of the ink glob up. [[File:Voltera calibrate_bad.jpg|border|none|300x300px]]

## In this case, to make an adjustment, the ink height was set to a '''Z of 0.09 mm''' and the flow was set to an '''E of -10 um.''' This dispenses less ink than before.

## '''You may need to do the same or make different adjustments. Whatever you do, do NOT run the nozzle into the board! The nozzle will break!'''

## If an adjustment was made, '''wipe the board clean with a paper towel (shown below)''' and repeat step 9. [[File:Voltera calibrate_wipe.jpg|border|none|300x300px]] <br />

## If an adjustment was made, '''wipe the board clean with a paper towel (shown below) and/or clean it with isopropyl alcohol''' and repeat the calibration. [[File:Voltera calibrate_wipe.jpg|border|none|300x300px]]  

## The example below is a more acceptable test print. Strive for this consistency. If your board looks right, proceed. [[File:Voltera calibrate_better.jpg|border|none|300x300px]] <br />

## The Voltera will print what is selected in green. Below is an example of a portion of the board selected. Ensure the portion you want to print is selected (in this case, select everything.) Remember that blue lines will not be printed. [[File:voltera_selection.PNG|300x300px|none]] <br />

## Click "Start." Let the Voltera finish its process. If a portion of the print fails or is incorrect, you can stop mid-print, or wait until it is finished and redo that selection. Also shown below is an example of a portion of ink that globbed up. The portion was wiped and can be reprinted.

## When you reach the "Flip Board," you are done. Quit the Voltera application.  

## When you reach the instruction titled "Flip Board," you are done. We want to bake these traces on the Reflow Oven before we do anything else to the board.  

## Unclamp the board from the Voltera. Remember that the traces are still wet.

## Unclamp the board from the Voltera, and remember that the traces are still wet, so do not smear them around.

## Consult the Reflow Oven wiki and complete that process.
