Hi,
I'm building my first 3D printer, and I'm struggling with a challenge. I'm testing my stepper motors and, although I can make them move correctly, I can not make them move very quickly without them stalling. If I move the engine more than approx. 1500 mm/min in octoprint they stop moving and just make a terrible noise. The engines run freely, I have not yet put a load on them.
My printer is a CoreXY design, and I have only connected the x and y motors to my RAMPS 1.4 card. I am using DRV8825 drivers that are set to a voltage of 0.650V, which should give a current of 1.3A. I have until now only connected drivers to the x and y axis. The drivers are set for 1/16 microstepping. The power comes from a PC power supply and I have only connected the 12V to the 5A-port of the RAMPS.
The motors are RTTM 17HS8401:

Am I doing anything wrong, or can these motors not move faster?
Edit:
I just wanted to add that Marlin is set up to 100 steps/mm. :-)
