Test Code Not Working I've been banging my head against the wall for the last week trying to figure out whats wrong. The test code found on the reprap wiki blinks all the leds on the ramps 1.4 board but the stepper motors don't move. The pots are set between .65 - .70. The motors are not vibrating nor are they moving. https://reprap.org/forum/read.php?160,601158,601158#msg-601158 Sat, 18 Apr 2026 22:38:25 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?160,601158,601940#msg-601940 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601940#msg-601940 Dust Stepper Motors, Servo Motors, DC Motors Tue, 29 Dec 2015 02:48:09 -0500 https://reprap.org/forum/read.php?160,601158,601906#msg-601906 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601906#msg-601906 BillyGoat Stepper Motors, Servo Motors, DC Motors Mon, 28 Dec 2015 21:44:16 -0500 https://reprap.org/forum/read.php?160,601158,601894#msg-601894 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601894#msg-601894
he presumes the voltage regulator has blown in such a way that its not putting out any voltage, This is not always the case, often a damaged regulator will output a random voltage.
You should remove d1 from the ramps to stop any voltage going into the voltage regulator (under X and Y stepper driver module)

You would use + and - pins of the endstops if you where using these to supply 5v to the ramps and mega.

I would just power it over USB myself, either from a pc or a 5v 1amp power pack (one of those with a usb plug on the back, so you can just move the usb cable from pc to power pack as needed)]]> Dust Stepper Motors, Servo Motors, DC Motors Mon, 28 Dec 2015 20:01:04 -0500 https://reprap.org/forum/read.php?160,601158,601765#msg-601765 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601765#msg-601765 BillyGoat Stepper Motors, Servo Motors, DC Motors Mon, 28 Dec 2015 13:08:19 -0500 https://reprap.org/forum/read.php?160,601158,601565#msg-601565 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601565#msg-601565 -Olaf]]> o_lampe Stepper Motors, Servo Motors, DC Motors Mon, 28 Dec 2015 03:28:30 -0500 https://reprap.org/forum/read.php?160,601158,601508#msg-601508 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601508#msg-601508 BillyGoat Stepper Motors, Servo Motors, DC Motors Sun, 27 Dec 2015 22:19:56 -0500 https://reprap.org/forum/read.php?160,601158,601495#msg-601495 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601495#msg-601495
Thats a 12v 5amp plug! not 5v... 5v is not enough voltage to move the steppers. (Luckily this doesn’t cause any damage)

both are meant to be 12v.. the 11amp cct is for heated bed, the 5amp cct is for steppers and hot end and is fed into the mega which creates its own 5v.]]> Dust Stepper Motors, Servo Motors, DC Motors Sun, 27 Dec 2015 21:02:35 -0500 https://reprap.org/forum/read.php?160,601158,601397#msg-601397 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601397#msg-601397

You say your running test code, but the LCD shows your running real firmware...

If your running real firmware get the controller to tell you what it thinks of the endstops

Ie send m119 to the printer, any that say triggered, it will not move in that direction.

I ran the firmware to post the X:---

Endstops all report open when running M119 through repetier

The test code doesn't move any of the motors with or with out the endstops.]]> BillyGoat Stepper Motors, Servo Motors, DC Motors Sat, 26 Dec 2015 22:35:32 -0500 https://reprap.org/forum/read.php?160,601158,601186#msg-601186 Re: Test Code Not Working https://reprap.org/forum/read.php?160,601158,601186#msg-601186

IMG_1045.JPG seems to show your endstops... these look to be two wires, and look to be in the incorrect place (they look like they will short - to + when the switch is closed... this is really bad) If they are 2 wire endstops they should be on S and - pins. They could be 3 pin endstops, in which case they may be fine. I can't see that from the pictures

ie two pin endstops (all set to min endstops) look like this



Now after saying this, the test code doesnt check endstops... But its they are shorting 5v to ground... you will have issues.

I would say you have you motors wired wrong.

check the motor wiring, ignore any color codes, as no two suppliers use the same colors and some even change the colors week to week.

read this http://reprap.org/wiki/Stepper_wiring you have to identify which two wires on your stepper motors are a coil and make sure those two wires are together on the ramps connector (pins 1 and 2 are first coil, pins 3 and 4 are second coil)
