Instructions

expect a Sherline machine to stand up to the rigors of continuous production use.
Continuous use of stepper motor driven leadscrews in a production environment can
introduce wear that would be impossible to produce manually. Therefore, slides, gibs,
leadscrews, leadscrew nuts and bearings that are subject to high wear due to continuous
usage are not covered under this one-year warranty.
Non-warranty service and machine tune-ups
Sherline machines are easy to service, and all replacement parts are available from the
factory. However, if in the future you wish to return your machine for any reason to have
Sherline repair or adjust it, we will be glad to do so. Our shop rates are very reasonable
and our production people have all the proper tools and fixtures to repair or service your
machine quickly and return it to factory new condition.
Returning machines or parts for warranty or non-warranty repair
Before returning any tools or parts for repair, please call first and obtain a Return
Material Authorization (RMA) number so that we can process your order immediately
upon receipt. Remove all non-essential parts from the machine to save shipping weight
and return only the portion to be repaired. Wrap and package all parts securely so they
cannot move around in shipment. We recommend that heavy parts be double-boxed.
Include a brief written description of the desired repair and your return address and phone
number or e-mail address inside the box so we can contact you if questions arise. Repairs
are normally return-shipped the next workday after they are received.
Technical Support
If you have a physical or electrical problem with a machine, component or accessory
manufactured by Sherline, please feel free to contact us at 1-800-541-0735, 1-760-727-
5857 or [e-mail]. If you have technical questions regarding the
functions Linux or EMC that are not answered in these instructions, the Linux group
maintains an excellent website at www.linux.org that has a search function and a lot of
helpful information. Remember that Sherline hasn’t charged you a single penny for the
Sherline version of the EMC2 program even though we have spent a considerable amount
of money and time adapting the software to the Sherline mill. Our CNC instructions also
include a free basic course in the use of g-code. Beyond that, we recognize that many of
our customers are new to machining and to CNC, and we will do our best to put callers
on the right track to the information they need to get their new CNC system up and
running. Learning to use g-code and learning to cut metal beyond what we provide in our
instruction manuals must ultimately be the responsibility of the machinist, but we will
help where we can.
A short history of CNC
In order to shorten the instructions and get right to the operation of the machine, this
introduction has been moved to the Sherline web site at
http://www.sherline.com/CNChistory.htm. If you are new to CNC we urge you to read
this introduction first, as it will give you a good background on how we got to where we
are today and why the instructions are presented the way they are. The following
instructions are divided into Part 1, which covers the basics of connecting your computer
