from my reading of the leadshine manual on page 14 from what we can tell it is saying switch 4 should be off for reducing the idel current?

Not in my manual see pic.!


If you change the Amp setting which you really should then you'll need to re-tune the drive. Always re-tune with any changes made.

this is what we have been going by and what I got from there website. page 14

Try this one.

hmm that's interesting that it seams to suggest the opposite very odd! will try switching the settings according to that!
Many thanks

This is correct and it does work 100% tried tested many many times. .

Great thes good news! Many thanks indeed I will change switch 123and 4 then re auto tune. I'm still trying to down load a driver (see other thread) and when I figure that I will ajust the Amps

Now I'm slowly starting to understand it a little more I'm Just wondering if I can improve the x axis as well with the kinco drive as we have noticed it is a bit notchy at the slower speed at ether end of the cuts so just wondering what I should have the micro steps set at for that? It is running a 4:1 ratio (yet to sort out the 6:1 box) I will take a look at what the other seting we have it set at tomorrow. Realy apresiate your patience!

So continuing with the above post the x axis is set switch 1 to zero which is only 2micro steps and switch 2 to three which I think is right which is the 6a peak setting for the 8nm nema 34 and like I say at slow movements at ether end of the boards I'm cutting is quite lumpy and at full speed it still looks like it is hardly working. Can I up the micro steps on the x and possibly the y and z too? How do you determine what they need to be at?

Charlie setting the micro steps higher makes the motors run smoother, thou at a very slight expense of some torque but it really is nothing worth bothering about and the trade off is well worth it.
Problem with high micro steps is that you need much higher number of pulses(frequency or Kernal speed in Mach3) to get the same speed or move the same distance. Normally with the parallel port this becomes a problem because it's too much strain on it with higher MS and can't cope so you get missed steps etc.

You how ever listened to uncle Jazz and bought Motion control card and a very good one to boot. So you can crank up the MS and not worry to much.
So set the MS to at least 1600 (sw3 or 8 micro steps) or 3200(sw5) wouldn't hurt (thou 1600 is good enough.) and listen to the difference and you'll also see it when going very slow.

Edit: With the Csmio-IP-M card the Kernal speed in mach is ignored so leave it set at 25Khz.
