ShopBot PRSalpha - Zeroing the XY Axes; Changing Bits

Quick-Start Guide for PRSalpha and PRSstandard tools
Zeroing the XY axes
The best way to zero the X and Y axes is by using the proximity switch homing process. This process
instructs the machine to touch o from each switch to establish a zero locaon, which creates an accu-
rate and repeatable start point.
Click the XY Zero buon or type a C3 command to use this feature. To make a permanent adjustment
to the locaon of your 0,0 point based on the switches, click on [T]ools > ShopBot Setup, and “Next”
unl you see the screen that’s marked “ShopBot setup: Prox switches.” Then click “Click here to make
it easy on me.” The program will help set up the new permanent zero locaon.
To set up a temporary zero locaon, simply move the spindle/router to the desired locaon. Write
down these coordinates to ensure the exact locaon for later. Type a Z2 (for Zero 2 axes) command.
Noce that the X and Y coordinates now read zero. This is the new 0,0 locaon that the cut le will ref-
erence.
Changing bits
Note: Spindles and routers have dierent collet styles. Instrucons are included for both.
Make sure collet and nut are completely clean. If necessary, use a wire
brush, compressed air, and/or mineral spirits to remove dust or excess
grease.
Spindles: Before inserng the bit, press the collet into the nut and listen
for the “click.” If collet does not seat, press it in at a slight angle. Conrm
that the collet is snapped in by holding the nut upside-down and leng the
collet hang freely.
Routers: The router collet and nut are held together by a retaining clip.
It is not necessary to disassemble the components for cleaning or bit
changes.
Slide bit into collet. Make sure that
the collet grips only the shank of the bit, keeping any parts of the
ute outside of the collet. Ideally, the bit shank should ll at least
75% of the collet.
Thread collet and nut onto router or spindle. It should go on very
easily. DO NOT apply force if nut is resistant. Stop and try again
unl it goes smoothly. Once the nut is nger-ght, check the bit
again to make sure that it has not slipped. Use the included
wrenches to fully ghten nut.
Spindles: snap collet into nut,
then ip it over to ensure it is
snapped in securely
Ensure no part of ute enters collet.
