Hi,
At the moment im in the process of changing from parallel to ESS "SmoothStepper", to do this it is recommended that one "downgrades" from Mach3 version 3.043.066 to Mach3 Version 3.043.062, my question is, will the Mach3Mill.xml from version 3.043.066 work in Mach3 Version 3.043.062?
Thanks in advance for your help.

Hi Steve,
Its not downgrading it's changing to a version that is known to work well with the ESS.
Yes, you existing .xml file will work just fine.

Hello Tweakie,
Thank you for your fast answer.

Hi,
After changing from parallel to ESS, ESS is connected and running, two motors don't react and one (Y) only moves in one direction?
Thanks in advance for your help.

Hi Steve,
First thing to do is perhaps check that you have the ESS port 1 connected correctly (pin for pin) to your BoB.

Hi,
got that sorted out, thanks for the help.
now the display shows the workpiece being milled correctly but on the table the mill does the work "turned" 45° to the left. where can i correct this?
Steve

90° I can understand but 45° is bit of a mystery.
Does your Gcode file contain a G68 command ?
Tweakie.
-
Hi,
No G68 in the G code.
i just tried swapping motor output settings the x & Y step pin & dir pin, this makes the mill do a 90° turn.

Hi Steve,
Try adding G69 at the beginning of your Gcode file.
Does this correct the 45° rotation issue ?
Tweakie.
-
Hi Tweakie,
set the pins back to "45°" setting then added added G69 to the G21 G90 G91.1 G64 G40 line in the gcode, no correction to be seen?

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

Hi,
infomation that might help.i stand to the side of my mill always have done up til now without any problems, i.e what i see on the Display is what i get on the table looking from the side.
i use an xbox joypad for jogging.

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

here an example:
Display --> shows Tree standing up.
Mill (Looking from my position on the left) --> mills tree lying on it left.
Before my change from parallel to ESS it was.
Display --> shows Tree standing up.
Mill (Looking from my position on the left) --> mills tree standing up.
Steve

Yes your right 90°
Sorry

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.

Hi,
Where can i change this?
Steve
-
And how?
I tried swapping x&y the result was a 180° turn.
Steve

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,
Tweakie thank you for your patience it worked.
just did my first Routing with the new Stepper, the result is ok just a "little" small, the proportions are correct.

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.
