Hello @AV1987, that's great to hear! Have you adjusted the A4988 stepper driver by turning the little bolt on it? That controlls how much current flows to the stepper motor, which may be causing the slow movement. Check this link which explains it well and how to adjust for your stepper motor.
Hi @ProjectsWithRed I did try both increase current and voltage on 3x A4988 drivers. All of them slow like slow motion :) Also, each of them pulling only 250mA Whatelse could it be?
What step configuration do you have on the A4988 drivers (the MS1, MS2, and MS3 pins)? You can also try to increase the speed of the motor by using these two variables, LINMOT_STEPPERS_SPEED
and EXTRUDER_STEPPER_SPEED
.
@ProjectsWithRed I keep your original sketch with exact same hardware setup. MS1,MS2,MS3 connected like your schematic. it shouldn't be moving slow. Could it be the motor wiring? Can't be because i swap A & B still the same
Can you link the exact motors used? Also, try increasing the LINMOT_STEPPERS_SPEED
and EXTRUDER_STEPPER_SPEED
variables.
@ProjectsWithRed Good idea! RTELLIGENT Nema 17 Stepper Motor 3PCS, 2 Phase Step Motor Bipolar 1.5A 59.5oz.in(42Ncm) 42x42x38mm 4-Wire 30cm Long Cable for 3D Printer (3, 42A02C-XH2.54) https://a.co/d/7eo0juY
@ProjectsWithRed Forgot to quote your replied: yes i did change it to 200, that didn't help. Here's exactly problem when I turn it on (after uploaded sketch):

@ProjectsWithRed
@AV1987 No its not normal. Are you sure you changed the bolt on the A4988 stepper drivers to the correct current for the motors? Check this link, which explains it in great detail.
Hi @ProjectsWithRed I got my setup is running, I leave everything same as your original sketch it seems matches with my calibration. A new problem for me why these motors are moving very slow like "slow motion" Please advise Thanks
