XY Plotter v2.0 mDraw Does not work properly

#1

I originally posted this in the announcement of mDraw for the xy plotter, but just in case it has been miised there, I am posting it here.

Benbox works perfectly with my newly constructed XY Plotter, but mDraw does not.

If you click on the mDraw drawing space to move the pen, SOMETIMES
the plotter pen moves to the correct place, but often it does not, instead one
of the axes will move but not the other, or the pen will move in the
wrong direction. If you then click on ‘home’ either nothing happens or
the pen again moves to the wrong place. Its difficult to describe, but
its as though the software ‘loses track’ of where the pen actually is.
Its very random and difficult to identify a pattern, but it makes the
software completly useless.

I’ve tried redownloading the software several time and re-uploading the driver to the Orion Board, but nothing I do fixes it.

Benbox works perfectly, so its not a problem with my machine.

Such a pity because mDraw looks to be potentially a better option than Benbox.

@HarveyC.
such case i encountred is that the endstop pin floating. the endstop may stop the motor and set a wrong home position, make sure that endstops is connected properly even if you don’t need them. if it is not the problem of endstops, would you please send me a snap shot of the console log, thanks~

Albert,

Sorry its taken me so long to get back to you.

I’ve checked the endstop microswitches, and they are working just fine according to a test meter on the ‘far’ ends of the connection leads. But one thing that I have noticed, is that regardless of the limit stops being engaged or not, when you click on the little ‘gear’ at the top right of the screen, the XY setup window always shows that the limit switches are ‘off’.

Hope this helps diagnosing my problem.

Regards

Harvey
