Hi Gary,

Slaving the X and A axes.

As said, I am not an expert at this because I have never had occasion to actually do it but…

In Motor Tuning make the settings exactly the same for both the X and A axes and save the settings for each.
In General Config uncheck the A-Axis so it makes the A axis Linear.
In Slave Axis select X to A then restart Mach3.

You should now have both these axes slaved.

Hi Gary,

Assuming I understood your description correctly this is how I arrived at the figures…

Your steppers are 200 steps per revolution – that is 1.8 degrees per step.

When you set 1/8 micro-stepping (8 micro-steps per 1.8 degree step) this increases the steps per revolution to 1600.

You have a gear reduction of 20 tooth to 60 tooth which equates to reduction of 3:1

You have a 20 tooth pinion running on a 1.5mm pitch rack so one revolution of the pinion moves it 30mm along the rack. This makes the equivalent lead-screw pitch 30mm.

Hi Gary,

I don't use slaved axes so I am not the best person to ask about this one.  

I calculate your steps per at 160 assuming I got everything right.

Hi Gary,

It depends on your leadscrew pitch and if you use Imperial or Metric as it is perhaps better to arrive at a nice round number but I would recommend that you set your driver board to 1/8 microstepping (dip switches 5 & 6 OFF) then Al's calculator should help you to arrive at the correct steps per unit. http://www.machsupport.com/forum/index.php/topic,16315.0.html

Hi MP,

Welcome to the forum.

Perhaps best to post your question as a new topic in the general section - it will receive more coverage there and I am sure someone will be able to help.

Bit of an educational project here with more details in this thread http://www.machsupport.com/forum/index.php/topic,24021.0.html

The material I used was 1.5mm thick polycarbonate. I have kept the feed-rate low but you may want to increase this using the FRO slider. The overall size can be scaled, if you wish, by using the X & Y axis scale DRO’s.
This tool-path has been created for use with a 2mm diameter end-mill with the X and Y zero (datum point) centre of the stock and Z zero with the tool touching the stock surface.

Excellent news Gary. 

Problems are so often caused by the most basic things which we (myself included) overlook or take for granted.

I doubt it is relevant in this case but this is typical of problems that can be encountered with some of the Chinese manufacturers product. http://www.phlatforum.com/viewtopic.php?f=128&t=9421

I am sure you did the wiring correctly - looks like a thorough job in your pictures.
