its on .378

 

yes port 1

 

yes

 

Ok so in that case when you jog you should see steps on pin 2 and direction on pin 3,

If you jog the x do you see the dro figures move?

Sorry if I'm sounding patronising btw it's not intentional just helps to visualise what's going on

 

it oky your fine i get no movement of motors

 

If so put a multimeter over the Gnd terminal and pin 3 terminal, when you change direction you should see a voltage

 

The dro is the Xyza figures in the top right of Mach 3

 

the figures are the position so if they are not moving neither are you outputting any steps so need to confirm Mach 3 is outputting steps before continuing

 

oky motor runing

X -MOTOR MOVED BUT JUST RUNS

 

Brilliant, your almost there then. Most likely an active low unchecked. So what changed that made it run?

 

MOTOR LIKE MOVES SIDE TO SIDE LIKE ITS STUCK

 

No infact, it's well past my bed time, active low should make a difrence it shouldn't just run. Could you have your driver direction and steps wiring round the wrong way.

 

just vibrating and not moving? Two causes you have your motor poles wired wrong or too little current to drive the motor. It's only doing it when you jog tho yeah?

 

Two windings with both sides of the winding bridging both channels of your driver will make one winding try to go one way and the other the opposite way and cancel themselves out. I think, it's 3 in the morning I'm not sure of much right now but worth checking

 

YEA THEY ALL RUN BUT TRY TO MOVE ON STEP LOW

 

Oh and need to set your motor tuning, 400mm/min 50mm/ps/ps is a good place to start for x and y, half that for z

Got to hit the sack, good luck. Sounds like your on your way. Takes an Intire week to set my machine up from scratch, calibrate and test it. And pretty much same with my ox. Have fun.

 

SAME HERE THANKS

 

Almost forgot, you need to do a steps per calculation, as default they are set real low and will make your motors go super slow especially with microstepping

 

is this what your talking about http://micro100.hsmadvisor.com/?page=FrontPage&shell_id=247&load_tool_id=4763

 

No that's for calculating feeds and speeds of cutting, search for steps per mm calculator.

This is what i got useing the gt3 belt on this site

 

Well if you enter that into motor tuning and then go to tools tab should see a button axis calibrate or setup or something similar in the bottom left corner, you can enter a dimension for it to travel, measure once travelled and enter that distance and see if it calculates a similar value, if it does I suggest you leave it with the original calculation over the Mach 3 calculation as it's usually more accurate

 

oky

sir the x is going back and worth

 

Lol is it not supposed to?

 

oky i had the red and green wire on motor wrong so i switched them and now it move to the R and L but moves so far and stops

 

? i have the ox buils with 4 motors can i hook the to Y ASIX UP TOGETHER

 

Oky i got every thang moveing

 

oky my X is only moveing in one direction any help

 

You're driver most likely isn't receiving the direction signal.

Yes you can put both y and a (the other y driver) into one port on your bob, simply reverse the wiring of one of your y motors coils, ie choose a channel at the driver say b make pos neg and neg pos. so one motor turns the opposite way
