When do I need to calibrate?

• You will need to calibrate each time you take down or move your Ditto projector, if the unit is bumped, or if a different mobile device is used to project patterns.

What do I do if my app shows calibration success, but the projected image looks odd/off?

• Select the Calibrate button again and redo the calibration process. It should only take a few minutes.

My lighting is off; what is the best way to fix this?

• Calibration works best in a dimly lit room. You may need to cover any nearby windows.

Can you calibrate on an uneven surface, like a table with a dip or ridge in it?

• One of the requirements for Ditto is a flat work surface. Ditto’s calibration technology was designed to calibrate easily with a snap of a picture and eliminate the need for any manual adjustments. The system fully calibrates on its own through an algorithmic calculation.

What if I’m using a very thick fabric like Sherpa, faux fur or heavy fleece?

• If you use a thick, fluffy fabric, remember to calibrate with the fabric spread out and the cutting mat placed over it. Calibrating this way accounts for fabric height and ensures accurate sizing. When the system is calibrated, put the cutting mat back under the fabric. Trace or cut on the wrong side of the fabric. Calibrate the projector again before tracing or cutting additional fabrics of standard thickness.
