General Mach Discussion / Third axis for Mach3turn
« on: April 06, 2014, 07:21:17 PM »
I'm getting along fine with Mach3turn but Mach3turn only shows the X and Z axis.

I'm setting up a toolchanger and found an Icon called "lathe" so I got it all set up to run my lathe and the toolchanger.   The toolchanger is the "A" axis.
All is well until I wanted to turn a radius.   The radius is more of a bevel than an arc.

It appears in this LATHE window Mach3 still thinks it is running a milling machine.   I detected that in the progress window.

I need to convert this LATHE window in Mach3 to lathe mode rather than milling mode, OR

Or, I need to add the "A" Axis to Mach3turn.

Which is ever is easiest.


General Mach Discussion / Activation file?

I purchased Mach3 on a CD.    What is the file name that needs to be copied from the CD to Mach3  to activate?
Thanks Jim

General Mach Discussion / Mach3 won't run program
« on: October 03, 2013, 11:36:39 AM »
I just set up and got running a smooth stepper.   However I have a problem I think is unrelated to the smooth stepper.

I have a fresh download of Mach3 on a Dell laptop.    I also have a copy of Mach3 on another computer that has been running since 2009.    I have tried to duplicate all the settings from the older download to the new download.

My milling machine will JOG in all three axis's just fine.   The calibrations seem right.   But, load a program into Mach3 and all it does is show 4 concentric
circles in the toolpath window even though the program is 4 tiny holes that are inline.   Run the program and Mach3 Machines a huge circle.   I loaded another program without any circles yet Mach3 display the same huge circles.

The only thing different between the old computer and the newer (2005) computer is the CPU speed.

I have setup Mach3 several times and never ran into this.      Seems like Mach3 had setup program that told me a bunch of things to do but not this time.

I don't think this problem is related to the smooth stepper.

General Mach Discussion / Mach3 turn; jog third axis

My Mach3 turn only lists the X and Z axis when in JOG mode and no Y or A axis.

I would like to get an A axis to JOG when in Mach3 turn.    How do I do this.

General Mach Discussion / Need Encoder for threading
« on: June 03, 2012, 12:00:05 PM »
I tried to do a search on "Encoder" but had no results.

Anyway, I'm doing a retrofit on a Denford CNC lathe.

Retrofit almost done

To cut threads I mounted a stepper motor to the spindle.
Stepper motor setup

 For normal turning the timing belt needs to be removed from the stepper. It works great for theading plastic but lacks the power to thead steel.
see it cut threads

Can somone recomend a source and part number for a encoder that can be used with Mach3 for threading?   I should be able to mount the encoder
where the spindle stepper motor is.    I'm using a Bob Cambell breakout board.

I have already read the Mach3 download about threading.   The download did not mention the encoder used.

Thanks   Jim Glass
