General Mach Discussion / Re: Mach3 Slave Problem - novice user

Hood,

Thanks for your reply.

X axis seems to respond to jog.  Y seems to not respond or is hit and miss with gantry racking.

Ports and pins include X Y Z and A axes

Motor tuning seems OK

Slave configuration is X with A slaved to it.

Don't see anything on the Gen config page relating to slave???

General Mach Discussion / Mach3 Slave Problem - novice user
« on: May 14, 2009, 10:10:09 AM »
I recently built a router using a mechatronics drive, 4 - 269oz steppers and Mach3.  I had problems with the X/A slave axis but I got it running.   I  moved controller box to the computer stand and am again having problems with the X/A axis.  I am getting a condition abnormal that reads "one or more axis disabled or enabled".  I have double checked the configuration and played with the motor tuning but no success.   Y and Z axis run very nicely.   Just the X w/A slave being a problem.

I assume this is a Mach3 configuration issue.   What am I doing wrong.   Assistance appreciated.

Gerry,

Thanks for your reply! 

Some details first. 

Router built from 1/2 and 3/4" aluminum tooling plate.  42" X 16" X 6" work envelope. Linear ball bearings and Thompson ball screws/nuts on all axis.  Motion seems to be very smooth and easy when moved by hand.   

The steppers are 269oz from Xylotex.  The controller is a 4 axis unit from Mechatronics.  24 volt power supply. Limit switchs installed.  I am using a digital multimeter.  VREF is adjusted to 4VDC.(Max reccomended vref is 5VDC).   PFD voltage is adjusted to reccomended 2.5VDC.

Running Mach 3. With motor tuning set at 7878 steps per , 79.98 velocity , 20.182788 accelleration.

Y and Z axis perform very smoothly.    X axis has A motor slaved to X.  X axis motors seem to stall or don't move at all making high pitched buzzing noise.  When X does move it seems to move slowly.

I don't understand what the PFD does and wonder if it needs adjustment???

Thanks,

Jack

General Mach Discussion / Problems with A slaved to X on Gantry Router

I just completed building a gantry router with two lead screws and steppers on the X axis.   I set up the A as a slave to X and am having poblems with the motors not actiong in sync.

Any insight as to what I am doing wrong?

Chip,

OK, I'm back.

Where do I find the XML folder.  All I can find is a "xmlbackups" folder.   Did a search for "normals" in windows explorer w/o success.

Thanks,

Jack

OK, double click the abnormal button and click yes in the pop up window.

Reload Mach3 and see if all is well.

Yes, I have been considering that but then have to reconfigure for the machine.   Probably what I will do but I'd sure like to know what happened!

Thanks,

Jack
