SmoothStepper USB / Help with SS and Servo drives please :(
« on: April 22, 2010, 07:34:31 PM »
I have everything setup up and my friend has made me a g-code test file, but for some odd reason it keeps losing track of where it thinks the spindle is and loses its true soft limits. the smoothstepper is driving a cnc4pc's C10 BOB and thats connected to me servo drives.

When i ran the file that my friend did for me, i zeroed in my tool to my work piece then set the program off. initially the first line of code told the tool to do +10.000 then go down to a depth of -2.000. mach thinks its done this but in reality its only moved about -5mm from the original +10.000. if you leave it to run, it moves again to -4.000 as if it were doing a second pass but then goes all loopy and plows my tool through the table more or less.

On a second run of the same file it did not try to kill my table but to kill my X axis. as i have two motors moving X (A setup as a slave to X). For some bizarre reason tried moving A in the opposite direction of X.

One last thing is when i move the Z up and down then run abit of code, then stop and try to manually jog the Z in the + direction, there is no movement but mack thinks there is. the Z - works fine. I have to restart mach 3 and it works again.

My Servo drives do give of a large amount of interference when i enable them to "run", i have yet to successfully get my limit switches working because of this.

Altering de-bounce does not effect anything in anyway.

At the moment i have the SS board by my PC and the BOB is located in the cabinet with the Servo Drives and spindle inverter.   setup is like this ... PC --- usb cable --- SS ---- parallel cable --- C10 BOB --- screened cable --- Servo Drives
Heres a pic of my servo drive and bob.


hope someone can help

Cheers

hi hood, ill have a look at my wiring, the DRO does count up or down but no movement at all, the funny thing is that ive just tried it on another pc that was working fine and its doing the same on that, so to me it points to something on my wiring side of things having an effect on mach3! i dont have any limit switches active or anything like that as my machine is not built yet and its just on a bench for testing only.

hi guys, im in the middle of building my cnc machine but all my motors are wired up and were working fine until i decided to fire up my mach3 software and give the motors that i have at tho moment a spin! all was working fine untill just, out of the blue the Z axis will not move and i keep getting the error safe z turned off ignoring safe z move! ive not touched anything since last time i had a mess with it and it was working fine! it wont move when im in the motor tuning setup either.

Ive looked at a few settings but im new to all this and i cannot see what could be the problem!

Anyone have and ideas or has come across this before?

Im not that well up with the mach software as you can probably tell so go easy on me ;)
