General Mach Discussion / Re: Motor noise question

The Active Hi / Active Lo on slaved motors will not be causing the problem.

What microstep setting (on your controller) are you using for the slaved axes ??   Is it different from the other axes ??

Hi Dsx,

Please contact the supplier where you obtained your 3020b for backup and support in resolving this problem.

Hi Fred,

When you make a post (assuming you use the reply button) or when posting a new topic - there is a box which says 'Message Icon'. The usual icon is 'General' but if you click the arrow you can choose the icon that best suits your topic.

I have a small dog at the moment who really does not like cats (pretty much the usual with small dogs) so I have no cat at this time but I still have a soft spot for cats, thus the avatar.

It's the 'Message Icon' Fred - there are various options and just for demonstration this message has been posted with a smiley.

Hi Leeawilson,

Perhaps check your MeshCam generated Gcode to make sure it does not contain a G20 code which would make the machine operate in Inch units instead of your desired mm units.
Motor tuning is in units so if Mach3 is set up for mm then that is what is displayed.

Hope this helps,

General Mach Discussion / Re: Position Errors Only on Diagonal Moves

Hi Nate,

It beats me but I think you have ruled out everything but your machine electrical's and the tuning of your servo's.
Are all your voltages correct and being maintained during the run ? - Are all your electrical connectors truly sound ?

Running your Gcode, using a laser, the centreline of the toolpath produces a 1.2" square on the first pass and a 1.25" square on the second pass. Both the X-Y aligned square and the 45 deg. square are absolutely identical in dimension - there is no error.

So I think I can safely say there is absolutely nothing wrong with your Gcode or the Mach3 interpretation of that Gcode.

Hope this helps in finding your problem.

Thanks for the PDF link Terry - I have just learnt things I did not know about drilling acrylic.
