trouble with pulse rate to 2nd axis
« on: June 05, 2012, 06:51:28 AM »
I am one of the ebay system buyers,4 axis 1600 oz/in cnc kits. I have everything wired, only x and y on machine so far. This is a dm860a driver,60 volt power supply,x220806 bob,1600 oz/in nema 34 motors. I have a .200 pitch 5 tpi ballscrew with 20 tooth timing pulley on motor and 40 tooth on lead screw i can run at 2000 steps and get good feed and torque but when I calculate my trave I am 1/10 my needed steps,The driver has no dip for 20,000 steps but has 25,000.when I set x or y to 20,000 it works as long as I keep the Y set at 2000 but the y is very slow. If I set both to 20,000 steps both move slow no matter what settings I use for accel ect... I did my system check up tp 100,000 and it said excellent but still no good. I have licensed mach3. I Know there is not alot of info on this but any help would be greatly appreciated as the wife is about to kill me if this doesn't work. Thanks

received email from mary long sent video of setup worked like a charm seeing is it for me, lots of power but not a barn burner knee mill, this is a 1985 jet jvm840 10x30 table very well built and heavy for a medium mill. anyone needing help on some of the out of country stuff give me a shout might be able to help. I still have a .001 backlash on both axis, got 2 more axis to install z and dividing head. Thanks for lookin and letting me post here.Goin to bed now!
