Plasma Torch, first try and lots of questions

2

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:

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




switches for power supplies motors and switches for motor drivers as well
