Hi Jim,

It won't actually do any harm if the step and direction pins are wrong - it just will not work. Similar story for the step / direction active state. My suggestion would be to experiment until you get it right then note the settings for future reference.

Hi Phil,

Just post as a new topic here http://www.machsupport.com/forum/index.php/board,1.0.html

(I did try to move the last couple of posts to the correct place but failed miserably  )

Some of the Chinese imported machine controllers set up and run perfectly some just refuse to toe the line - I will keep my fingers crossed that you are one of the lucky ones.

So my long winded question is can we have the program on both sides of the Atlantic, uk side connected to the mc, USA side only connected for training?

Hi Phil,

Yes sir, you can.

The demo version is not locked in any way it is just limited to running a maximum of 500 lines of code.

Under the terms and conditions of the Mach3 license - Provided you are not actually running CNC machines, for commercial purposes, on both sides of the Atlantic then your one license can be used in both instances.

Tweakie.

A Quote from the terms and conditions...

Non-commercial users (aka hobbyists) are permitted to use one Mach license for as many machines as they require. For commercial users (anybody who uses the software to generate profit), we require a separate license purchase for each machine. Mach1, Mach2, and Mach3 may all be used on one computer, but only one version of each will co-exist on a single computer.

A license is only required on the computer actually running a machine (Mach) or generating G-code (wizard software). If a computer not connected to a machine is used to test code, please use Mach3 in Simulation mode – it will remove the 500 line limit. Simulation mode can be accessed by uninstalling (or not installing) the Parallel Port Driver.

Hi Jeff,

Perhaps the GCode M11P1/M10P1 commands are the way forward - it is the system I now use.
This document and the attached comments refer http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29

Hope this helps.

Hi Radu,

Welcome to the forum.

Yes please start a new thread (new topic in the General section) this is a most interesting idea and I think may be a quite a challenge to resolve.

Hi Bob,

Welcome to the forum.

If you post your question, giving as much details about your machine / setup as possible, as a new topic in the general Mach discussion section I am sure someone will be able to help.

« on: May 19, 2014, 01:36:23 AM »

I am pleased that you have been able to solve the problem.   

It relates to the I/J Mode and how your particular CAD/CAM software creates the arcs - the Mach3 manual section 5.6.6.2 perhaps explains it better than I can.

General Mach Discussion / Re: h-bot can mach3 run them?

« on: May 14, 2014, 03:12:09 AM »

can I run it with 4 motors 2 each side and simply wire them together

In the good old days when stepper motors were only operated in whole steps it was common to see two or more steppers wired together (either series or parallel) and driven by one controller chip.

Since the introduction of micro-stepping, modern stepper controllers are 'smart' and use emf feedback to control motor windings current when holding position – connecting two motors to one controller chip confuses the logic and it is now regarded as bad practice.

In line N0040 change the G90 to G91.1   Does this produce the desired toolpath ??
