BACK_TOOL_LATHE = 1 in the INI.

 I have a new problem that I can't solve. For the first time I have a turret back !!!. I have placed the scale [-] atand it works fine !!. but the margin of x machine axes in AXIS appears reversed. I am using 2.7.14 on this lathe.

is there any way to specify to linuxcnc that the turret is back ? image

File Attachment:


 

Actually for the Axis GUI you need both both LATHE = 1 and BACK_TOOL_LATHE = 1 in the [DISPLAY] section.

linuxcnc.org/docs/2.8/html/gui/axis.html...g_axis_in_lathe_mode

Also this is not in 2.7.

Thanks a lot!!!!.

I was reading the 2.7 documentation, I will leave it like that for now and I will update later !!!.
the X axis is fine !!. it's just visual.
I'm glad that 2.8.x has an easy solution

Thanks a lot  BigJognT - andypugh !!!!!!

You can put in g code file:
G10 L2 P0 R180 (Rotate around Z axis, 180 for back tool, R0 for front)
I use front and back tools in the same program with gang tooling.

Although there is a bug in 2.8 that requires a work around.

Is that bug listed in the bug tracker?

I already have the X axis working fine.

But I noticed that the  X JOG keys are reversed.

Can it be reversed? or do I have to change the direction of rotation of the motor?

Thank you!!

Is it actually wrong? Jog + should move further away from the spindle axis.

jog-X-reversed manual movement

the x-axis works perfect, the coordinate system is now well defined. only the manual movement of jog X was reversed

Axis and jog X coincide in their + and - signs.  But the X axis moves reversed and correct in its + and - signs.

They are dissociated, both are doing well but inverted between them

remember I am using 2.7.14. !! Should I update to 2.8.2? is this necessary to fix this problem?

I'm dizzy and I don't know if I'm doing something wrong

Are you talking about jogging from the GUI, with buttons, or with an MPG?
