General Mach Discussion / Home ref all stepper stop when hit home/limit switch
« on: July 23, 2013, 06:57:06 AM »
Hello
I have been using Mach3 for a while and my CNC router seams to work well.
The only thing i have not been able to figure out through looking on the help forumns is why when i do a REF ALL the steppers move to the combined home/limit switch hits it and the stepper stops, all 3 axis do this, to get it to start i reset and the y axis will do the same and then the x. I have tried various values in debounse upto 2000 but nothin has changed, as surgessted by HOOD.
So what this mean is that i do not ref all after turning on my table and i do not use soft limits.
I make sure that when cutting i use a working cord of 0,0 well within the table area.
The limits switches stop all axis if hit but i have no safety control if the axis run off the table area ( the reason of having soft limits set)
I have checked and all the DRO count up/down in the correct direction
I have the limit/home switches at the bottom left front corner of my router table and on top of the z axis
i have tried changing motor acc and vel setting and my motors run smooth
I am using a USB controlled board.
Any help would be welcome
