Hi
My name is Aurelien from France.
Sorry to ask here, i'm machinekit user but i does not foud help or information from machinekit group untill now, and i think you have do much work for CNC feature.
I knwo that the code is now many different but for this parts i have check and "all" seems to be the same.
I have a lathe (mechanicca cortini H105s) and i have retrofited this one with some beaglebone, driver new stepper etc.
The things that make me asking help is the manual tailstock changed as motorised stepper tailstock.
major settings :
[DISPLAY]
DISPLAY = axis
LATHE = 1
GEOMETRY = XZW
[TRAJ]
COORDINATES = X Z W
AXES = 9
JOINTS = 2
# W axis
[AXIS_8]
TYPE = LINEAR
Tailstock seems to work fine for standard command.
But i have do some test for show what is work and not work (turning speedle manually and simulating spindle-at-speed to 1) :
-G33 W-15.5 K1 work like a charm in G18 so is ok
-G33.1 W-15.5 K1 does nothing (i can see in Axis GUI after other command the status is like "run program" but this one change nothing)
-G73 W-15.5 R-10 Q1 need to be in G17.1 plane : lathe with XZW ????
-G81 G82 G83 need to be in G17.1 plane : lathe with XZW ????
-G76 "cannot move rotary axes with G76" off course this is fully out of interest for a lathe with W, but W is linear and i have do this only for test all synchronised stuff^^
I have check source code for G33.1 and i have see some difference vs G33 regarding to parsing value
I have try to patch all the needed file in /src/emc/: now i can see in Axis GUI the status is like "run program" but motor don't move.
After more check in the source tree i think also need to patch some other file like tc.c tp.c but i have some trouble understanding how to do this for stuff like "xyz/uVec" any help are welcome.

Unfortunatly i think they are other problem, i have read that is not possible for a lathe to wait spindle at 0 rpm before reversing direction or maybee this is not an issue for the stuff i likle to add ???

I really like to know what do you think about that ?
Br, and happy new year to all.
