Plasma Torch, first try and lots of questions

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 !!!

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??

tried that with new setup , motor test , is not faster ......
clueless ..if I touch the motor you can see the rpms...a stepper should go faster well ?????

also a new setup did not help...tested the motor ......

now it's time to go to bed, I get an error and can't figure it out ????

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
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 ....

It will be a configuration error in your in file I have to go so can't help

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
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 ...

setup for squaring and laser test
