Slow feed rate on stepper driver, solved Anyone with a good clue here? I'm building a reprap, and i'm testing motors. Setup is an arduino mega 2560 with ramps 1.4 and an 12V 8A psu. Just one nema17 hooked up. When i move the axis in Pronterface/Repetier Host, i can't go beyond 150mm/m at 50% on the stepper driver. Anything beyond that, e.g. 155mm/m, regardless of stepper driver setting will just result in vibration and screaming stepper. Same thing goes for when i try homing that axis, then it'l just do the same, so i'm guessing it moves a lot faster there, then by manuel movement? Anyone with a good hint on what's wrong? Kind regards. https://reprap.org/forum/read.php?160,384803,384803#msg-384803 Mon, 12 Oct 2026 14:54:20 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?160,384803,384990#msg-384990 Re: Slow feed rate on stepper driver https://reprap.org/forum/read.php?160,384803,384990#msg-384990 Azuria Stepper Motors, Servo Motors, DC Motors Fri, 18 Jul 2014 16:11:38 -0400 https://reprap.org/forum/read.php?160,384803,384803#msg-384803 Slow feed rate on stepper driver, solved https://reprap.org/forum/read.php?160,384803,384803#msg-384803 I'm building a reprap, and i'm testing motors.
