Are G33 & G76 supported in Mach3?
« on: July 17, 2020, 03:49:56 AM »
I'm investigating 'Thread Milling' but cannot find any details about the parameters I need to add after a G33 or G76 call. Using the [ G-Code ] button in Mach3, these codes are not listed so there are no 'hints' and I can't make head nor tail of what is supposed to happen after I select the 'Thread Milling' Wizard -- it simply shows me a new screen with Exit. Post Code, etc. along with a number of apparently editable dimensions which return to the initial state upon exit. The [ Post Code ] does not alter the 'No File Loaded' message.

Since I am looking to make 'large' (but short) threads  -  100 - 200mm dia and 2 - 4.5mm pitch  -  using a single point tool a 'Tap' is not an option  :)
I understand the complexity of threads needing a very specific feed rate in the Z axis which will not (necessarily) be the same as the feed rate in X & Y but cannot yet see any G-Code that will achieve that.
Any input appreciated!

Thanks for the input TPS but that is about Mach3TURN  I'm looking for a solution for Mach3Mill  - sorry I should have made that clear in my post  :-[

for thread milling i am using a cam Programm called Estlcam.
it is cheap and easy to handle, also for other parts to create cnc code.

sorry the side is in German, but the Software can be switched to english.
anything is possible, just try to do it.

Thanks, I'd already found that video and watched it before your re-post came in  :)
It looks to do the business - though that video only shows 'Standard' threads, I'm sure 'specials' are also catered for. 

What it doesn't tell me is what parameters I need to enter when writing G-Code by hand.  Yes I am a masochist!   ;D

Is that as far as Mach3 is concerned?
I see G76 listed as also available as 'Fine Boring Cycle for Milling' which seems to suggest that the Z feed can also be specified as a separate parameter.  It also 'Includes OSS and shift (oriented spindle stop and shift tool off centerline for retraction)'  -  I just can't find any reference to the form that the parameters take.
