General Mach Discussion / 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

newbie all around , I am a knuckle dragger by craft (industrial Mechanic). I have done civil engineering and worked with the US Army Corp of engineers, precision millwright for 10 yrs and Machining off and on my whole life, There are 2 things that i struggle with, electricity and computers(and I build a cnc!). My son is an electrical engineer but has very little free time so this prodject has been mine alone so far. I really enjoy this site and hope that some of my issues can be helped here. Thanks for having me and will be picking brains soon enough.
