Brian, How do set the  step pulse width to 5-8 ? Is that in my motor tuning settings?
I attached a screenshot of the motor tuning and my xml file

Hi Brian, Thanks for the reply. I am running in sherline mode now. I will try the step pulse width. How do I take out the screw mapping?

Yes it is different. I setup everything from scratch. I will post it tonight when I get home. Thanks

Ok - I uninstalled mach3 and deleted the directory and started the setup from scratch. everything is much better now except for the following problems:
- Machine is inconsistent on axis travel distance - moving 1 inch does not yield one inch all the time, very inconsistent results. I tried the button under settings tab to test the movement and setting the motor steps but it keeps increasing my motor steps every time.
- Even though the machine is referenced and homed, my ref all button moves the axis beyond softlimits. when I jog the softlimits work just fine, but If I press ref all it moves beyond softlimits.
- Under screw mapping, the length for all screws is 1300. I am not sure what that number is and I could not find a reference to it on the internet. Is that the correct setting. My y and a screws are 43" from tip to tip and my x is 26". Z axis is 12".

Thanks Hood, I'll enabl enhanced pulsing.
to recap:
- When I jog x, x moves and when I jog y, y moves - no problem here
- When I ref x the y/a axis moves in the positive direction. When I ref y, the dro numbers increase in the positive direction but the y axis it does not move on the table.
- When I click on go to Z, all axis go to table 0,0
- when I click ref all, the y dro increases in the positive direction but none of the axis move on the table.
I posted 2 zip files under a different post (mach 3 strange behaviour). They have pictures of my machine and screen shots of my settings.
I also have a video that I can send you that shows the exact problem. it is 10mb file.

   Hello all, I am a newbie to cnc. I posted some pictures of my 24X 36 machine and my mach3 setup screenshots for anyone who can help me with this. I also have a problem with circle g-code that comes with mach3 download. It turns into an oval on my machine. My machine has very strange behaviour right now. When I press ref x diagnostics page the machine moves in the y direction. I have a Dyna1000 and the led indicates that Y is moving but the dro shows X increasing in the positive direction from machine 0,0. When I reference Y in the diag page, The dro indicates that Y is moving in the positive direction but the machine itself does not move at all. And when I press soft limits (set to 23,0 for x and 35,0 for y and a and z to 0,3) the machine says that I am out of softlimits for softlimit activation. Thank you all in advance for helping a newbie. I will post the files in 2 replies.

Ok, Sorry It took me long to reply. I made the change and it made no difference. My machine is at zero location. When I click on ref y, The DRO for Y counter increases in the negative direction. but the axis it self on the machine does not move. I am trying to set the soft limits and I am getting an error of machine out of limits for softlimit activation. Please advise. Thank you
