Troubleshooting

Each section lists checks in the order to try them. Most problems are the first check.

A tab or a button is dim

A dim control is waiting for something, never broken.

What is dim	Why	See
Everything but Wizards, Design and Help	No machine profile yet	First launch
Projects, Macros, History; the jog pad	The machine is not homed (or not connected)	The homing gate
Save Pos, Load Pos	Not homed, not moved since connecting, or no position saved	Saved positions
Overrides	No job running, or Enable Speed Override off	Feed and speed overrides
The Design, Manufacturing, Parameters tabs are missing	No design is open	The Designs panel
A drawer's commit button	The drawer still needs a pick or a value	The drawer's own prompt

The state tag: Offline means no connection; Alarm means the controller stopped itself — see After an alarm.
The Notes card: Machine not homed means home first.
A jog toward the edge of travel is blocked: the Notes card says At X+ machine limit — jog blocked. Jog the other way.
A job is running or held: the jog pad waits until it ends.

The drawer names the reason; the fix is in The Control screen. The usual ones:

Work Zero Not Set — set work zero on the Location card.
Work Zero Is No Longer Valid — a reset cleared the tool length; set Z again.
Work Envelope Exceeded — the job does not fit the machine at this zero; move zero or the stock.
Export out of date — the design changed since the program was posted; regenerate and export.
Sign-In and License Required — see License.

Look at the toolpath in the view before starting. Is it on the stock?
Check the active work system chip: G54, or the one your program uses.
G54? with a question mark, or +G92 under the chip, means the datum is in doubt or offset. Check Work coordinates.
Was zero set at the corner the program expects? The Tool Run's WCS Origin says which.
Did you zero X or Y by touching an edge? Zero is at the tool's centre; allow for its radius. See Setting work zero.

Problem	What to check
A design will not open: saved by a newer version	Update Prime Motion
Designs are missing after removing the SD card	Reinsert the card; designs on the card stay there. See Settings → General
A sketch says its face reference failed	Its menu's Repair face reference or Re-home to XY; see The design tree
A toolpath shows a red ⚠	The model changed since it was generated; Regenerate it
Text cannot be extruded	Its font is not installed, or it is a Single-line font; see Resources
An STL imports at the wrong size	Re-import and choose its Units; see Importing STEP and STL

the Version from Settings → About;
your machine and controller, as Settings → Connection shows them;
what you did, what you expected and what happened, with a screenshot if you can.
