This is a very good question, Starting with the last question first, Yes it common where the design recommendations are ignored and sometimes it is successful. Many times it not because of warping...
Water will always flow the path of least resistance, This maybe a situation where you don't have enough pump to get the water to where it needs to go at a good pressure. However since your needing a...
If you keep a constant parameter specifically Max Injection pressure, you risk the possibility of over packing the mold during the first cycles resulting in flashed parts, sticking or stuck parts...

I agree with Crabstix in thinking a good direction to go is checking and making sure you have power going to each potentiometers. It would be helpful to know if you have rotary or linear pots. The...
There is good information and design guides from Dupont thermoplastics Resource Center. Check out Design guideline module 1 starting around page 10. It has examples of what you are trying to do. Some...
