Hi,
the picture you posted shows 1,2,3 as ON,ON,ON which is 1.5A.
What you want is 1,2,3 as ON,OFF,OFF which is 4.2A

Notice the 'ON' icon and arrow on the dip switch block...

Hi,
as I said earlier try reversing switches 2 and 3 only.

Craig

Hi,
I didn't find that exact table but that is the model I think it is you have, so 4.2A is correct.

I think you are confusing the direction of the switch and it on position. Looking at the icon printed on the switch block 'ON' is with the toggle
to the right. The picture shows 123 as on,on,on.

Craig

yup changed it to 1=on 2=off 3=off  now 4.2a steps same power save off

Hi,
kool, let it rock...

Craig

its rocking moving smoother noticed the motors are warm but not hot.. yet?! will keep you all posted thanks for your help feeling positive.

well tried to make another box today more fire wood, still messing about motors got quite warm so think I might drop the voltage a bit. So checked the PC its running xp pro service pack 2 barely any services switched of all networking as well as its in my workshop, anyone any ideas? motors (mainly X but not exclusively) sometimes just squeal instead of moving until next command is sent then moves on to destroy the work. Cant think whats left to check slowed it right down as well low acceleration speed etc. HELP!

Hi,
if you can't hang on to the motors they're getting too hot and you should reduce the current, a bit....say from 4A to 3A.
If they are not going above 50 degrees Centigrade then leave them alone.

That squeal is a stall. It doesn't sound great but it doesn't hurt the motor at all. From your description it sounds like the stall occurs when
the machine is instructed to move at G0 rate, ie maximum. Sounds like its struggling for acceleration.

What are your current velocity and acceleration settings?

Run DriverTest.exe and post a screen shot if possible.

Craig

so power now down from 4.2amp to 3.2amp motors ok heat wise. Steps are 1600 speed down from 900 100 acc recomended to 700 acc 50 this stall happens under load or not I actually tried to stop the machine by hand to put it under strain no chance. stall can happen on any axis but mostly x . I ran the driver test computer came back excellent, no background programs running cut out all nonessential services its so fast. I'm running out of ideas
