Spindle Warmup Routine (C5)

Before running an ATC file make sure that the spindle has been properly warmed-up. Failure to
warm the spindle could lead to premature spindle failure. Type C5 (“Spindle Warm-up Routine”) to
start the 9 minute routine that ramps the RPM through 3 different speeds and then shuts off. If the
machine sets idle for longer than an hour, run the warm-up routine. If unsure whether or not to run
the warm-up cycle, go ahead and run it to be safe.

Run the File

Open the file and run by typing (FP) or clicking the “Load Part File” button on the ShopBot
position screen.

If Something Goes Wrong

If for some reason the ATC does something that is out of sorts, use the (C3) command. This will
home the machine and reset it back to the original table base coordinates. Always verify X, Y, and
Z locations before continuing.
