General Mach Discussion / Re: E-Stop not working

« on: May 09, 2017, 07:09:13 AM »

I hook up the micro switch for limits on X axis to P11 & GND and it does nothing when the switch is activated.

This switch must be using the Normally Open (N.O.) contacts and the Mach3 Input related to pin 11 must be configured as Active Low.

(The other switches are then configured in a similar manner).

Generally the problem is caused by electrical noise or it could be caused by bad EStop / limit / home switches.

Try lightly tapping the switches with a screwdriver handle and see if this triggers the Estop condition.

The electrical noise immunity is set within the ESS config. so follow the Warp9 setup guide for the optimum settings. If this makes a difference then you need to investigate and tackle the source of the electrical noise.

Hope this helps.

Hi Steve,

Excellent news my friend.

On the Settings (Alt_6) page there is the Axis Calibration feature. You could use this just to check that you have set your axis Steps per Unit correctly. Just follow the on-screen instructions.

On the main page are the Axis Scale DRO's. If, for example you changed both the X axis and Y axis Scale DRO's to +2.0000 (press return after each change) then the part would be made double size. Using these DRO's a part could be made to any scale size or 'flipped' by using a negative value for one axis. The possibilities are many.

Config. / Ports & Pins / Motor Outputs.

Swap your X axis Step Pin# and Dir Pin# with your Y axis Step Pin# and Dir Pin#

If any axis then drives in the wrong direction (see earlier diagram) change the Dir Low Active state for that axis.

Hi Steve,

No problem 

The actual layout of the X and Y axes usually depends on where the operator stands in relation to the machine (A Mill, for example, may be configured differently to a Router).

You should change your axes (port and pin configuration) so that the direction that the cutter moves in relation to the work piece should always be as shown in this diagram.

So your work is rotated 90° to the display not 45° ?

Another question:

If you use the keyboard left / right arrow keys to jog the axis does it move at 45° ?

Hi Steve,

Try adding G69 at the beginning of your Gcode file.

Does this correct the 45° rotation issue ?

90° I can understand but 45° is bit of a mystery.

Does your Gcode file contain a G68 command ?

If your machine is set-up in mm and you run a Gcode which has been prepared in Inch units then add G20 to the start of the Gcode file. This will then run the file with the correct dimension.

Ideally all Gcode should contain G20 or G21 (as appropriate) as part of the initialization string.

And as you have discovered, all Gcode files containing arcs should also contain G90.1 / G91.1 as appropriate.
