*'''Ejector stroke position''': These settings control the positions of the ejector pins in the retracted and advanced position. It is recommended to leave the 'Ejector retracted position' around 25,6 mm. The 'Ejector pin advanced position' can be fine tuned if you have problems with unreliable robot pickup, but 56,0 mm usually works well. If you make changes to the 'Ejector advanced position' make sure to adjust the robot take-off position as well. Otherwise you risk missing the sample or that the sample is pushed hard into the robot arm and thus risk damaging both the robot and your samples. As mentioned in the 'Closing mold' chapter, remember that the the 'Opening stroke' parameter also influences the position at which the robot must pick up the sample. | *'''Ejector stroke position''': These settings control the positions of the ejector pins in the retracted and advanced position.

*'''Ejector shake counter''': If samples are difficult to release from the moving part of the mold, this setting makes it possible to move ejector pins in and out several times to help releasing the sample in order for the robot to be able to grab the sample. Usually leaving it at 1 works fine (meaning the ejector pins will move out once and the robot will immediately attempt to pick up the sample), but in some cases it may help to increase the shake counter to 2 or 3. | *'''Ejector shake counter''': If samples are difficult to release from the moving part of the mold, this setting makes it possible to move ejector pins in and out several times to help releasing the sample in order for the robot to be able to grab the sample.
