Hi , just finished a leadscrew 1000x1000 workbee build using nema23 motors , Arduino uno , protoneer shield with drv8825 drivers. it seems to sometimes have one y Stepper lag behind when jogging , it doesn't happen everytime but mostly if I do a large 100mm jog. I have set driver current to 0.9v running a 24V power supply , this is where they seem happy and quiet , I had it at 1.4V but the motors would not drive properly . I can up the power supply to 36V , would that help ? Motor specs Step Angle：1.8° Rated current：2.8A DC Rated Voltage: 3.36V Winding dc resistance（25℃）：1.2Ω±10% Winding inductance：2.3mH±20% Holding torque：≥1.26N.m Shaft diamater: 6.35mm or 1/4″
I had problems with my DRV8825s due to overheating. They would lose steps on larger jobs. Are you cooling them real well with a fan, or fans?
Problem temporarily resolved dropped ref voltage to 0.8v and added better cooling fan . Think i need to reconsider the drv8825s and find a better stepper driver solution .
I switched to the DQ542MA drivers and have not looked back. My fear was that I would be running a long job and at 90% complete they would overheat on me. For the DQ542MA drivers I used an arduino screw shield to make the driver hookups easier.
Thinking about going to the tb6600 drivers , cheap and can still hookup to my protoneer shield . did a 6 hr test cutting air last night, cooling made a big difference no steps lost but I am also worried about long term , its running at a lot lower current than is desirable.
I believe others have used those with success. Here is a post/thread that may help you. Stepper motor won't move, any suggestions? (Solved)
Well i fitted up the tb6600's to the arduino using a 36v 11A power supply . Using nema23 1.26nm motors . Instantly better setting current limit to 2.8A Found on the 1/16th microstep the motor would stall if i jogged faster than 5000mm/min. Dropped microsteps back to 1/8 and then was able to achieve 6000mm/min with a scceleration of 100mm/sec2 without stalling . Happy with the outcome .
