making my machine distance work accuratly

i will get this distance in the morning!

I'm not sure if you missed what I posted, but you dont have to measure anything. It has all been figured out for you.
I have the exact same setup from the same company, but I have the 2:1 belt ratio on mine.

If you want to enter it into stepconf
then enter:
Motor steps per revolution - 200
Driver microstepping - 10
pulley teeth - 1 : 3.2
leadscrew pitch - .31831

.31831 is 1/pi so that makes sense to you.

The pinion has a 1" pitch circle, so each rev of the pinion is 3.14159"
with a 3.2:1 belt ratio: 3.14159" / 3.2 = 0.98174" per motor revolution
200 steps per rev / 0.98174inches per rev = 203.718 steps per inch
with 10x microstepping thats 2037.18 steps per inch.

ok!

thanks, i would have not been able to understand this. this make sense once you know.

will set it up over lunch today. stocked!

i am tryinng hard to setup a new board. i failed on the pmdx126, was a friend board and now i am doing mine.

i am doing what it said on this and my motors just run so bad and distance is still affected.

so here is the setup.
The R&P system is based on a pinion with a 1" pitch circle. The total linear distance traveled per revolution of the pinion is thus 3.14159". With the Nema 34 R&P 2:1 reduction, this means that the distance traveled per motor revolution is 3.14159 / 2, or 1.5708". If you have a stepper with 200 steps per revolution, this means you have 200 / 1.5708" = 127.324 steps per inch, or 0.007854" per step. With 10x microstepping (like in the G201x or G203V), you would have 1273.2 steps per inch, or 0.0007854" per step.

i want my setup in mmas i dont use inches whatsoever but i can convert later.

so for linux cnc in the configuartion wizard they ask for:
motor steps per revolution: 200
driver micco stepping :10
pulley teeth : 2:1 or 1:2 ??
leadscrew pitch: ?? REV per IN


thanks,
for some reason i can not get to 1273.2 step per inch

enter 1?

doesnt make sense. i cant get this right,

please leaborate. what is 1 gonna do? what do i write in the leadscrew pitch.

sorry guy, i really need someone to do it for me because seem like whatever i put in those boxes with all the info i put in previous post , my motors are moving the wrong distance and they are moving slow and rough. in the speed i tried for 300 to 10000 and nothing goes. in the velocity i tried from 1.5 to 150 and same.

is it possible that my board is not compatibe with linux cnc?
here is the board thati have.

sorry my ignorance but i still dont understand bigJohn comment, to put 1 in every box? is the stepconf wizard the most important part to mae the machine run?

those numbers have to be right dont they ?
i mean if i put the leadsrew with the wrong value the machine will never run properly ?

my motors are nema 34 from cnc router parts, every thing is from them.

what is confusing me is that on the bottom of the page (stepconf wizard, axis configuration) it say AXIS SCALE, on the CNCRP site i should get to 1273.2 step per inches, but i cant never get to that number.

if i cant get the step per inches right, the machien will never move at the right distance, am i wrong there?
