Oh great that worked , even 2 motors on gantry , axis toolpaths are as they should be.
the machine is fighting I tell you , my home switches are the only pnp no , I use cat5 for connections and exactly on the two motor gantry one home did not work due to broken wire !!!![:evil: :evil:](/media/kunena/emoticons/devil.png)
It took me a long time to find where.
I added the distance from home to max with 110 but when I travel the whole distance it show 470 only which is strange have to figure that out too.
further somehow the system is very slow I used the maximum which I could enter and still jogging is very slow.
I got 15.55mm travel per revolution that should be possible for much faster speed.
I add my ini and hal, since I got the wire problem I am already frozen
in my unheated Garage.
thanks again for your help .....

i'm a bit rusty, but pretty sure that jog speed is determined by DEFAULT_LINEAR_VELOCITY in your ini file and its a lot lower than the MAX_VELOCITY you have in your joint configs. I kept the jogging a bit under the max velocities.

Hi Rodw,
thx, funny it does not allow me to go higher on DEFAULT_LINEAR_VELOCITY, jumps always back to 1000 max...
I remeber when I just tested one motor the 7i76e on my kitchen table it was much much faster with standard settings...
Maybe I have to discard all and start a new fresh new one setup??

Try typing a G0 command from the MDI and see if its faster. If you you have a setting preventing the jogging to use full speed.

tried that after studying G codes ![:-) :-)](/media/kunena/emoticons/smile.png)
same speed!!
I read nema23 should be possible at least a view hundred rpms...mine is very slow...
should I do a latency test?
the error I reverted to a previous version of ini and hal file ..hope that solves the error message ....

I use the great suggestion from swolebro to use the git repository and the different stages , so I should be able to go back one step ![:-) :-)](/media/kunena/emoticons/smile.png)
I will see today.
The speed of the motors is clear I only use pncconf which limit to velocity 2000mm/min max and 1000mm/min default which is slow.
So no problem with that, I asked Chris so he will maybe change since I like the wizard a lot.
forum.linuxcnc.org/39-pncconf/38556-defa...ocity-limited#159847
2000mm/min makes in my setup approx 2 rev/sec 33mm/sec travel distance 1.3 inch/sec.

after a lot of help I got and still need , here some pics to view as thank you!!
I would make the gantry a big taller in height next time..wanted to make it flat but it's not necessary ...
home switch Y
setup for squaring and laser test
switches for power supplies motors and switches for motor drivers as well
