Also I just notice my elephant drives are set for 1000 pulses per revolution, should that be around 2000 ??
I am also running at 33,000 HZ

I always used geckos in the pass and never had a problem,
them Leadshine AM882's for 80$ if they work well that is pretty good deal :)

this is the ones i got now

General Mach Discussion / Knocking X axes, whats going on ??

Hello again everyone

I would like to Thank everyone for helping me out with this headache i mead project

machine was working fine, now all of a sudden the X axis knocks

you are moving the X axis and y axis at the same time, no problem until you change Y direction and knock
you can start, stop Y in the same direction and no problem, the second you change it direction X axis knocks
you can play with Z axis and every thing is fine, only with Y axis

What can be wrong ?? I am using 2 parallel ports one has the 4 motor and the other has everything else,
and them Stepper drives with the elephant on it

Thanks again

I understand, i think i will get a ESS for fun to play with and a copy of mach 4
I been having a hard time with this machine, it works well and all of a sudden it don't.
Tonight it started again
I move X and Y at the same time and when Y changes directions X makes a cluck and or knock and i am sure it misses a few beets, you can see it when looking at the spindle
And it seams like Mach 4 don't do it, but hard to tell, i cant get the keyboard to work hehe ( I will Print off the Manual )
I got them Chinese Stepper drives with the elephant on it, i think them will get changed for Geckos   

Thanks

Thanks Guys

After not getting anywhere I was trying to change the button macro, but when it comes to that i don't know what i am doing hehe
I will try that macro in the morning thanks
So Mach 3 cant really do what i want it to do ?? I am using parallel ports  
I have discovered a few more problems, i am starting to think i am wasting my time with mach 3 and should move to mach 4

Thanks again

Hello Everyone

My machine is now working pretty good, I am trying to have the axes move away from the switch more then it already dos
My Homing work good, but the spindle ends up off the table,
Is it possible to have it more a few inches after hinting the switch ??
I read the book and tried a few things with no success

Thanks

Right on, i use the same unit on the output side ??

Every wire on that machine is shielded, i made sure everything is bonded
even the power going to the spindle is shielded 

My Spindle is pretty much this pile of junk hehe

its 220v ac and out 100V DC i use the pot to control the speed and use a solid state relay to turn it on and off but disconnected the relay to try to eliminate possible problems 

Thanks
