Inverter

Programming the Inverter

Process is

1. UP (or DOWN) arrows to select PD number wanted
2. SET to display current reading
3. UP (or DOWN) arrows to select setting wanted
4. SET to store settings

SHIFT(button with both up and down) changes from single digits (0-9) to decades (10-90)

Correct Settings

For control from xPRO board

• Jumper is between 1 & 2
• PD001 is 0 (You need to press the green button to start the spindle. Seems setting this to 1 doesn't work)
• PD002 is 1

Grbl/Gcode

[Grbl] [| Gcode Reference]

Software

Main design

Fusion 360

Post processing through

• grbl from autodesks website
• an alternative post processor

Gcode sending/ control of CNC

Universal Gcode sender seems to be favourite at RML | Grbl Panel is the one suggested on the openbuilds website

bCnc seems to allow tool changes

Other

nccorrector gives another view of the gcode

Ian also suggested freemill but think this would replace fusion
