Author Topic: LatheCannedCycles Face Cycle - Strange positioning at start?  (Read 157 times)

Hello,
I am using Mach4 Hobby (Build 5036 but also tryed 6105) with the LatheCannedCycles Wizard. It works great so far, but I have some issues with positioning at the start during the FaceCycle. For example, I want to perform a facing on 12mm round bar at Z=40mm. But why is the line N0080 inserted? This causes my tool to either crash or travel unnecessary distances. Is this a bug where the X and Z positions are swapped, or am I using something incorrectly? I've found the Example folder (Mach4Hobby\Wizards\LatheCannedCycles\Examples) and the file "Facing-Simple.tap" doesn't include this line. But I can't find any option to disable the generation of it. Of course, I can manually delete the line from the G-code, but if I forget to do so after new generation, it can lead to a crash again.

Here is the relevant code snippet: 

Code: [Select]
...
N0070 M03 (Spindle Forward)
N0075 M09
N0080 G00 X40.1000 Z6.2000 (Positioning for Start of Cycle)
N0085 G00 X6.2000 Z40.1000  (Rapid move to Clearance Height)
N0090 G01 Z39.9000 F0.0190  (Cut in on Z-Axis)
...

Could you please clarify why this line is added and if it’s expected behavior?
Thank you very much, and have a nice day.
