I´m currently working on a custom delta printer running Marlin 1.0.2 firmware. To control it I´m using the Repetier Host software with the onboard Cura software to slice my objects. The printing works fine but it takes the nozzle nearly 5 minutes to move from the homing position at 250 mm to the starting position of the print near z=0.
I already tried to increase the travel speed but nothing changed. Can you guys please tell me how to increase the speed of my nozzle to move down to my starting point of the print?
I had the same problem, and I solved it by changing the Z-Axis Feed Rate to a much higher value (1000 mm/min.) in Repetier Host via Config -> Printer Settings -> Printer.
