Instructions

immediate practical need for small precision parts, you are on your way to joining the

leading edge of today’s modern machinists.

Again, you should remember that Sherline hasn’t charged you a penny for the custom

EMC2 program even though we have spent many thousands of dollars designing a

system and writing instructions that an average hobbyist can understand. In turn we

expect you the customer to make an honest effort to find the answers to your questions in

these instructions before calling Sherline on their 800 number. The only way that

Sherline makes a profit is by selling products it makes in the USA throughout a very

competitive world. We don’t make a profit helping you find careless typing errors in your

programs.

If you found my instructions useful and you are not reading them to operate a Sherline

machine may I suggest a way to show your appreciation and help a good cause would be

to donate a few dollars to my foundation that is dedicated to getting great craftsmen the

respect they deserve in this world. Check out

http://sherline.com/jmfound.htm and be

sure to visit the Joe Martin Foundation’s Internet Craftsmanship Museum at

http://www.craftsmanshipmuseum.com/ where the marvelous work of these great

craftsmen can be viewed and enjoyed 24 hours a day.

Using the optional 4

axis

The Sherline driver board was designed to accommodate the fourth (A) axis; therefore,

all that is needed is P/N 8730 rotary table that includes both the proper stepper motor and

the stepper motor mount. The A-axis is programmed in degrees. A minus entry will rotate

the table in a counter-clockwise direction. The A-axis can move in unison with the X-,

Y- and Z-axes. Use slow feed rates to avoid a situation where the A-axis cannot keep up

because of the 72 to 1 worm ratio of the rotary table. There isn’t any EMC software

available at this time to write the complex code associated with engraving or machining

on a round surface; however, I believe the type of parts that will be made by Sherline

machinist are straightforward and can be easily programmed. Engrave parts such as

jewelry will need special programs.
