Title: Mach3 to Mach4 - Thread conversion G76
Post by: Rimmel on July 09, 2024, 01:58:33 PM

Mach3 to Mach4  - Thread conversion G76

Trying to convert Mach3 thread to Mach4 but seem to be struggling a little.

I am just looking to convert a M10x0.75p external thead (Mach3) to Mach 4

I am running in Lathe Mode - Diameter and METRIC.

Mach3:

Code: [Select]

G18 G21 G64 G80 G40 G98

G0 Z10.0
G0 X9.9
G95
G4 P1
G76  X9.09  Z-19.0  Q4   P0.75  J0.03  L45  H0.03  I29  C1.0  B0.01  T0
Could someone kindly post an example of a Mach4 Metric thread (in metric mode).

thanks

PS tried the MachMotion wizard and that just throws out garbage.

I can't give you an example but have you looked at the 'Lathe Gcode Programming' guide in your c:\mach4hobby\docs folder? It explains G76 and the required parameters... may help you..

Yes - I've looked at the programing guide and used the achMotion wizard as well. But can get a metric thread to come out of it all. Hence my last resort of asking for an example.

thanks
