diy 3d prin drv8825 rumba motherboard stuck help

Thank you for posting details of your motors but you should not assume that we know what a "rumba motherboard" is. Please post a link to its datasheet.

What motor power supply are you using (volts and amps) ?

Have you correctly adjusted the current limit on the DRV8825s?

Try running each motor separately with this Simple Stepper Code. You will need to adjust the pin references to suit your connections. You may also need to set the drivers' enable pins if the motherboard holds them disabled by default.

im rewriting marlin now to add the [Gulfcoast Robotics] HEX Screw-In M3 EPCOS Thermistor im new to the tuning thing I was trying to tune the voltage not current wondering why it don't go to 10.5 volts then I read the run on current found the Stepper Driver Vref calculator still brain not all caught up yet but the power supply 360w 30a 12V 30A DC Universal Regulated Switching Power Supply 360W for CCTV, Radio, Computer Project, 3D Printer,LED Strip Lights,Home Appliance,etc: Computers & Accessories

got it guy thanks so much wires that came with kit were not right on the moter side was red blue black green they came blue green red black never ordering through them again man a wasted weekend

Never assume that wire colours mean anything unless you have a datasheet that is specific to the exact product that you have.


it was a kit came with everything in a box motors wires board drivers endstops they aren't wired right either

You have my sympathy. That can be a real PITA,
