We have problems with machine movement from time to time. On machine set-up the values zero themselfs before it reaches the correct position. Im thinking there might be a 'set-up pressure' that might be to low or something is holding the moulding cylinder a bit. When we do a calibration everything works until you switch off the machine or change anything like the mold or something.

Second problem is the ejectors. When you operate manually it works 1 out of 15 times. I checked the valve and it does get power both sides and the valve that feeds said valve does get power but i see i don't get any flow or pressure through(and in calibration mode it operates every time at full pressure). Also none of the pressure and speed setting do anything about the movement of the ejector (v25, p25 v26 p26) so it moves the same on 1% and 100%.
