Hi all, I've been working with aengel on the Xaar system using kyle's code and we noticed that in his code after the power up sequence has finished, he has a delay put in for 1000 ms. Does anyone know if this delay can be shortened or even taken out completely or is it necessary to protect the Xaar head?

I don't remember respecting this delay. However, please use lower high voltage, I run with 24...28V since february last year. I believe the voltage must be adjusted accordig to the ink viscosity.
