Lathe problem

[jal123sin]

Hello, the iosender lathe radius mode and diameter mode problem, it seems that it is impossible to distinguish the gcode x value is set as diameter of the cylinder. As the sample cut depth I set is 1mm, it show 2mm cut depth on the main display area. I have tried to switch between the radius and diameter mode on tag of Settings: App, it can only displayed the 2mm cut path. Please advise a way to solve this problem.

Is lathe mode enabled in the controller? Settings: Grbl > General > Mode of operation
G7/G8 is used to switch between diameter/radius in the controller, current mode is displayed above the X DRO:

Settings:App lathe settings are used by the lathe wizards.

Thanks for your promptly reply, I try to change the radius mode to diameter on the tag (Setting: App) as figure below but the DRO section still display Radius.

Send G7 from the MDI or add it to your gcode file to change to diameter mode in the controller. Settings: App configuration is for the wizards.

Thanks, it great I add the G7 into the nc file, it's working. But I just find another problem on the G3 r value seems not functioning. I attached the nc file.

Did you change the plane to XZ (G18)?
ioSender may display arcs as straight lines depending on settings, this to speed up rendering:

I just add G18 in front of line G3 and I didn't change the Arc resolution, the former value is (10) . Now I try 40 segments but no change, still straight line display.

G18 changes the plane of the arc, which has to be XZ if I am not mistaken. The resolution of the display of the arc is controlled by both Arc resolution and Min distance, reduce min distance to get more detail. These settings has nothing to do with how the arc is executed by the controller so it is not very important.

Ok, G18 works. It's displaying round corners now.
