TinyG v9 Testing

This page is just some notes for now but will ultimately turn into the jump page for testing a v9 with the test jig and also as a self-test w/o a test jig.

Required Equipment / Parts

Gcode | Parameters | Command | Description
------|------------|---------|-------------
G28.2 | _axes_ | Homing Sequence | Homes all axes present in command. At least one axis letter must be present. The value (number) must be provided but is ignored.
G28.3 | _axes_ | Set Position | Set machine origins for axes specified. In this case the values are meaningful. This command is useful for zeroing in cases where axes cannot otherwise be homed (e.g. no switches, infinite axis, etc.) (See also G92 Offsets)



No. | Item | Summary Description
--|------|--------------------
1 | TinyG v9 Board | Referred to as UUT for unit-under-test
2 | Bench Power Supply | Bench power supply capable of 2 amps at 24 volts. In the absence of a bench supply a standard 24 VDC will suffice, but some test steps will not be possible
3 | Stepper Motors | Five NEMA23 stepper motors with a current rating of approximately 2.5 to 3 amps
4 | Dumb Stepper Fins | Two Synthetos DumbStepper fins. Used to test slots 4 and 5

Setup

No | Step | Summary Description

1 | Wire and Verify Power | With the power supply On power-up the blue Power LED should light. This verifies 5v switcher operation and 

Tests

No | Test | Summary Description
--|------|--------------------
1 | Blue Light | On power-up the blue Power LED should light. This verifies 5v switcher operation and 3.3v LDO operation
2 | Fan Test | On power-up the 12v fan output should power a 12v fan. This verifies 12v linear regulator
3 | Programming | The board should be able to be programmed via the USB port using the BOSSA boot loader. On completion the RED indicator LED should flash slowly - approx once per second.
4 | Basic Motion | `{test:100}` runs 5 motors in sequence at high speed in both directions. Tests processor functionality as well as operation of step, direction, enable and Vref for all 5 axes. Requires two Dumb Steppers for 4th and 5th motors.
5 | Slow Motion | 
6 | Red Light |
