The default feedrate comes up as 6 IPM.  Is there a way to change that?

We generally like to home to the low limit on the x-axis (left/right) and to the high limit on the y-axis (front/back).  That way, the tool is out of the way so you can load material after it finds the switches.  In Mach3, that seems impossible because I can only set the absolute position at the limits to 0.00.  Is there a way to set the absolute coordinates to read something different?  In my case, I'd like to find my limits, and then have the absolute registers set to x=0, y=73.

EDIT:  I don't know how to change default feed rate.

Homing to Y=73.  Go to "Config"   "Homing and Limits"  set "Home Off" for Y to 73 and set "Home Neg" to off.

Hey Flipz,
    I'm not sure I understand what you want. You can change the speed your machine homes at in Config, Homing and limits. In the last column to the right % of speed. This is % of your rapids, motor tuning dictates this.  Also, if you want your DRO to read a work coord. of 73 once the axis is homed you can set that in the same place, home off column.

I hope this helps.

Oh, yea, baby.  Perfect!


Still looking for a way to change the default feedrate.  For those reading, this has nothing to do with the "seek limits" speed, but is the feedrate displayed when you turn on Mach3.  It always starts at 6 IPM.

I'm not sure how this would bother you Flipz.  Once you start a gcode it will have a feed rate in the code.

If using MDI then add feed rate to your first line.  It will stay at a setting until altered by gcode or MDI

EDIT:  I just tried it. You can also enter a feed rate into the DRO and it will stay.  I know this does not answer your question about default.  ;D

I know, I'm being picky.

However, it's set someplace and if I can get at it, I'll probably default to 100IPM - just because.

OK I'll be watching to see if you get an answer.    Greg

It can be done with the default setting.
