$25 = 500.000 (Homing search seek rate, mm/min)
$24 = 25.000 (Homing locate feed rate, mm/min) $11 = 0.010 (Junction deviation, millimeters) Measure also at the board to detect a bad/lose connector. If it doesn't help, put the pot meter back to its original position (compare it to the other 2 pot meters). You hear more noise if the stepper gets more current. Increase the current if the stepper doesn't get hot. This means you should measure a low resitance between pin 1 and 2 (and pin 3 and 4) on the connector at the stepper.

I guess, the stepper coil pins are A- A+ B- B+ (A is a coil and B is a coil), because the stepper pin layout on the driver board has this layout and Ramps and other grbl boards also use this layout. I searched the internet for half an hour but didn't find any information about the woodpecker stepper pinout. However I can't image the steppers wouldn't run at 12V. The power supply has enough power to drive these 3 steppers but the input on the board is 24V and your supply delivers 12V max. But i cant find any info or datasheet of the board to wire steppers motors. (Although I could be wrong) it should be as simple as power the shield and Mega.

Motor Works fine.įor some reason my instinct tells me it's a software issue or GRBL Setting issue that I'm not aware of.

I have taken GRBL out of the equation and run the stepper motor using a simple Arduino code and the Stepper Driver to control it. I have tested with multiple stepper drivers. I have tested the pairs of the motor to make sure that they match the data sheet provided. But have not been able to recreate that and don't know what I did to get it or lose it. I once had the motor very difficult to manually turn. So I know that there is power making it to the motor. UGS will tell me that the x axis has moved and I can continue to play with it in all directions but nothing moves.Īfter playing around a bit I have managed a few noteworthy things.ĭisconnecting and connecting has on occasion made the motor twitch once like it does on my 3d printer when I connect to the computer. Jogging the "X" direction will not do an damn thing to the motor. I can then Send the Code "$X" to go to a state of idle $132 = 200.000 (Z-axis maximum travel, millimeters) $131 = 200.000 (Y-axis maximum travel, millimeters) $130 = 200.000 (X-axis maximum travel, millimeters) $27 = 5.000 (Homing switch pull-off distance, millimeters) $26 = 250 (Homing switch debounce delay, milliseconds) $24 = 500.000 (Homing locate feed rate, mm/min) $11 = 0.020 (Junction deviation, millimeters) I Click Connect and my console comes up with my GRBL Settings And is in a State of Alarm My jumper settings are set to 1/16 step according to my datasheet on the GRBLDuino I've got 5 Volts when I test the driver across Gnd - Sleep & Gnd - RESET I've got 19.1 volts when I test the driver across the motor power supply. But from what I've read I can run 19 volts for short periods of time. The Motor is a small Bipoler Stepper motor. I have it set at 200ma which should be proper with the 0.4amp rating of the motor. I have followed the procedure from pololu on setting up the driver for max current. I'm using Pololu DRV8825 Stepper Drivers. I've supplied the Arduino with 5 Volts as I've found out that the shield doesn't supply power to the Arduino. I'm using Universal G Code sender to send a G Code to the Mega. I've Flashed it to my Arduino Mega and have a GRBLDuino Shield Attached to it. Once I get one moving, I plan on Adding more. I am trying to make 1 stepper motor turn using GRBL Mega Version. I am not an electronics wizard by any means, Most of my knowledge comes from countless hours of Youtube. My experience is limited but have played with a 3d printer/miller/Laser Engraver (Boxzy) for about the last year. I've read all sorts of problems, but none seem to meet my criteria. I know, This is a common Occurrence, but I Am Stumped.
