Hello,

I'm using Linuxcnc with a,x,y,z axis. (see 
https://www.youtube.com/watch?v=vw4KiemWCtI )
Therefore I have modified the maxkins.c transformation slightly so that 
it matchs to the machine geometry.

As a result:
- In Jog mode and switched to world coordinates a move in A-Axis causes 
a correction move in y/z axis depending on the relativ position to the 
rotational center of A axis. --> fine
- In MDI mode a F100 G1 A20 command works also fine as in jog mode.

So far so good
Two Problems and Questions:
1. The T-Planner for example in case of the linear interpolation (G1 
A20)  plans the move according the limits of the A-Axis (max acc, max 
vel) but this move could result in acc, vel for the y/z axis which are 
higher than they are specified in the ini file.
--> So the TP doesnot check/recognize possible limits due to inversve 
kinematics? Am I right? (May be also a Problem for singularities in 
serial kinematics, general question)

2. In my case in Jog mode and switched to Joint mode a move in the a,x,y 
or z axis depends on the settings of the "default vel"and max acc 
specified in the ini file. --> All is fine
If I switch to world coordinates the "vel sliders" (axis display) for 
the vel has no effect and it seems that the max acc is set to inf.
--> Could this be a issue due to the fact that I'm always using 
motion.adaptive-feed connected to some external analog input (feed 
override poti)? (In case of trivkins all works as expected)

Best Regards
Andreas/
