Hello folks, I am rather new here and  I have two projects that I am working on at the same time. I am not sure if this has come up before or perhaps this is new in respect to the Sherline
mill and lathe.  I have not seen anything like that in the Sherline site, or anywhere on the internet, for that matter,  including the CNCZONE, so I thought I post this here.  

1) I  am wondering if anyone has used or is using a Sherline Rotary table as an indexing tool turret?

I just tested a setup with the original Sherline Rotary Table on my Sherline Mill on 4th axis using AHA a pretty good older DOS software program (soon to be converted to Mach3)  and the rotary table seems to be doing a decent job, it is holding the tools,  but I am not sure if this will last for repetitive work or maybe I should consider building one of those air activated locking and indexing lathe turrets, as seen on some You Tube videos. ? but my logic is that a rotary table that uses a wom gear to drive it, naturally locks the table pretty tight when it indexes it. Any commetns, suggestions would be appreciated.

2) I also want to convert a Sherline Lathe spindle to one that indexes,  to machine hex flat on round stock.   I called a couple places to see if they have a kit retrofit,  one of the places
quoted me $3K for a complete system.  Doing some research on the internet, got me interested in doing my own indexer, as I think I can do my own setup for about 1/3 that price if I do some of the mechanical parts myself.  I am not just yet sure on the logic to tie it into Mach 3, but I don't think that will be a problem once the mechanical setup is worked out.

I want to use the Original Sherline Lathe spindle (Same as on the Sherline mills) since I have aquired quite a bit of tooling for it and most of the parts I make are small and delicate from 1/8"-1" round aluminum and plastic stock.

I understand I will need a hefty servo motor with an optical encoder, with high  rpm and torque to act as the power driver for the spindle - and  to hold "Lock" when in index mode, respectively. I don't think I will need braking or elaborate gear redutions with this setup, but I am still looking and comparing thoughts and ideas with cost and mechanical work involved.
I like simple but effective setups and if I can save time in machining some of the parts, even better, but if I have to design and make some mechanical parts myself, no problem.

Here is a list of things I am considering for this project. I have yet to source them, I have some idea but would like to lock on a final setup by the end of next month.  Any suggestions would be greatly appreciated. Also, if anyone knows of a specifc kit that I can purchase, I may have missed in my internet research,  please let me know. Remember this is for a Sherline Setup, so  It cannot be unnecessarily bulky, but a setup with some degree of finesse.

Mach 3 Setup:

Any one have experience with Mach 3 and the MAXPATH 42 routers?

How are you configuring the system so that this runs smoothly?

I have an XML file that MAXNC  Recently Sent me to try out but I cannot get MACH 3 to run G programs


1) if I followed the right procedure for loading the XML file in Mach 3.
2) Is there something else I need to do to the Configuration to get this setup to work?

Here is what I did.

1) Loaded Mach 3 (Trial Version) on a laptop
2) Downloaded the MAXPATH42 1.2  XML file MAXNC sent me  and place it into the MACH 3 folder
3) From my Desktop, Mach3 "LOADER" icon,  click on it and I see the file there
I click on, OK, and Mach 3 starts with Profile indicating MAXPATH42 1.0, in the bottom right area of the Mach 3 screen, so I know this loaded
4) Homing and manual jog of motors works fine. May require a bit of motor tunning on the x axis but I can do this later on.
5) Loaded G file Roadrunner to test system, I get Condition buttom "unstable" ??, E Stop keeps reseting and indicating Watchdog Timer error.
As a result the MAXPATH 42 router controller and motors reset, as well, going OFF, then as soon as the Reset is toggled via the Mach 3 screen, the controller resets and
so do the motors. 

Can jog OK , but running G Code program stalls,  nothing happens, sometimes I can see the code moving, sometimes I cant,  motors don't move
at all when I try to run G program, no sound indicating there is any action?  Try joggin and homing, this works!.

I am running out of options to try, except to ask here and in other forums . I am also going to go over the Mach videos, one more time and see if I missed anything.

Please help, if you can.



I am desperately looking for a schematic for a MAXpath42 controller so I can determine if the controller has gone bad.

Please, let me know  if you have a schematic for this controller.

I am going to be checking againg here often to see if anyone can help.


I have a dual reason for posting here and I hope that someone more experienced than I am can help me. I would greatly appreciated. I need to find some help today Sunday if possible, so if you are reading this and can get me an aswer or direct me in the right path I would be very thankful.

First of all I have read that Mach Version 3 might be suitable for use with a Maxpath 42 router, and this is what has been on my mind for a while now. I've been running this router I purchased from MAXNC just fine for a few years now with the original program it came with, but I want a more graphical control software and I think Mach 3 might be the answer.

The second part of my reason for coming here and signing up is, that I need a little help trying to find out if maybe my controlller went bad.  I know this is not a MAXNC forum, but I have tried elsewhere and have not being able to get help. So maybe some of you can helop me out here.   I was trying to cut a part last night and all of the sudden my router stopped working in the middle of a job, so I figured it might the controller,  the cam program ran  fine,  but it gave me  an error message "cannot communicate with computer" , so I think it is the controller board, but  I have no diagram or schematic to trouble shoot it.

If anyone has a diagram or schematic for the MAXPATH 42 controller board I would appreciate it, so that I can determine if anything is blow out.  First thing I need to do, then get it running again with the original software and then I am going to try to configure it for Mach 3, or anything that is more grpahically suited  for this machine.

The only think I miss about this MAXPATH 42 router is not having good technical documentaion with the machine, the original manual I received with it, is very basic and I have found that trying to get the company to asnwer questions is a little difficult. 

I hope I can get an aswer today, so that I can at least check some things and determine what indeed went wrong with my machine, then take it from there.

Thank You.
