To build this metal antenna rotator you will need a welder.
Bill of materials
| Part | Qty | Source | Price per Unit ($) |
| Nema23 stepper motor - Wormgear 60:1 | 2 | [1][2] | |
| Bearing for the az axis 100x135x25 mm | 1 | [3] | |
| Stepper motor driver | 2 | [4] |
Test and setup
rotctl -r /dev/ttyUSB1 -m 202 -s 19200 -t10
-t is to use \n as end of cmd
To test you will need to :
type P<enter>
then give position
The motors should move, if not check connexions.
Then you have to check that the endstop are working:
type IP1<enter>
type IP2<enter>
If the result end with ',0', and the endstop is not activated, its good. (if it's not good, revese them in the config)
If the two endstops are at 0 when reset, the homing will be peformed. Homing is alway in the opposide way of the motor (-max angle)
