I have just turned a JT2 taper with mach3's taper turning wizard, unfortunately the angle is not correct and I don't know why.

If you look at the finishing cut , this is incorrect to.
My machine is set to work in mm.
Any ideas what I am doing wrong ?

 X end +12.39 , Angle +2.335 , X Start 14.2 , Z End -22.23 , Z START +0.0 , Clearance 1.0

roughing feed rate +100 , Roughing depth +0.1 , Finish Feed rate +50 , Finish Depth +.05

The final finish cut Gcode also looks wrong

G1 X12.3084
G1X14.2029 Z-22.23
G0 X16.2

The spec for the JT2 taper is :- small end 12.39 mm, big end 14.2 mm,  Angle  2.335

General Mach Discussion / HB04 MPG - Mach3 Detent calibration
« on: February 14, 2016, 12:17:06 PM »
Hi Everyone,

I have a wireless HB04  Mpg working with Mach3.
When I move the hand wheel 1 detent it moves the Dro's more than the specified amount in the Jog setting.
Is there any way to calibrate the wheel? or have I got something else wrong?

E.g  if I move 1 detenton the handwheel, with the jog set to .1 it moves the Dro .1016

All help Gratefully received

Newfangled Mill Wizard / Countersink Option
« on: January 18, 2016, 04:39:23 AM »
Hi Ron,

It would be good if the hole wizards also included the ability to do countersink holes.

e.g set the countersink angle , and top diameter , then the system did the rest.

Kind regards


Mach4 General Discussion / Version 2803 Problems

**** Reference all Axis Home ****

HI everyone,

Can you confirm if the reference all home should be working the same as Mach3.

Currently my system does reset the DRO's to Zero , but does not motor over to find home switches.

Are there any other settings that I need to set befor this will work? or do I have to code this in the button script?

Or is this a future Mach4 enhancement?

Kind Regards


Hi Everyone,

Can we have a Mach4  release schedule.

This does not have to be exact, but it would be nice to have some approximate release dates and some idea as to what new features or fixes are to be included.

As each release is made this could be updated to form a version history, similar to other software products.

Best Wishes
