I am using an UNO, GRBL v.8 and a CNC v3 shield with DRV8825 drivers to control 3 stepper motors using G-Code Sender. The power supply is a 24v 20A 480w.
I am not running a cnc machine but using this setup for a completely different application. The 3 steppers are attached to 3 components in an HF antenna tuner. The application is really irrelevant as my question will be about how to achieve the most torque from my steppers given the setup.
I would like to learn how to achieve the most torque from the steppers for both homing and x,y,z stepping. After I home the steppers I will send a simple code like this to send the steppers to their preset spots: g90 g01 f200 x -.697 y-0 z -11.406
The stepper is a NEMA 23 size 2.5A 1.3nm 184oz in.
I have the DRV8825 drivers set at 1/4 step.
Here are my G Code Sender parameters:
Machine control step size - .1mm/step (under machine control tab)
$0=175.000 (x, step/mm)
$1=200.000 (y, step/mm)
$2=175.000 (z, step/mm)
$3=5 (step pulse, usec)
$4=150.000 (default feed, mm/min)
$5=150.000 (default seek, mm/min)
$6=28 (step port invert mask, int:00011100)
$7=25 (step idle delay, msec)
$8=10.000 (acceleration, mm/sec^2)
$9=0.050 (junction deviation, mm)
$10=0.100 (arc, mm/segment)
$11=25 (n-arc correction, int)
$12=3 (n-decimals, int)
$13=0 (report inches, bool)
$14=1 (auto start, bool)
$15=0 (invert step enable, bool)
$16=0 (hard limits, bool)
$17=1 (homing cycle, bool)
$18=0 (homing dir invert mask, int:00000000)
$19=75.000 (homing feed, mm/min)
$20=100.000 (homing seek, mm/min)
$21=100 (homing debounce, msec)
$22=1.000 (homing pull-off, mm)
Thanks for your help!
