General Mach Discussion / Re: Xhc control card connecting to sangmutan bldc spindle control

Perhaps I am misunderstanding your setup or what you need to do but as you do not have any Mach3 Enable signals connected I assume your servo's lock their position when power is applied to the machine and freewheel when the power is turned off.
If this is true then I would energize the brake electromagnet (to release it) from the same circuit that supplies the power to the machine - when power to the machine is turned off then the brake is automatically applied. I envisage this to operate totally independent of Mach3.

Craig,

As you say the motors all pass the insulation test but I would be very concerned about measuring a current as high as 30mA between the machine frame and Earth.

It may be better if you start again from scratch making fresh downloads...

Download and install the recommended version of Mach3 (3.043.062)
Download and install the appropriate Windows Driver (2.08.30)
Download and install the appropriate Plugin (v17fd)

(it goes without saying but make sure all downloaded zip files are properly extracted before installing if it is done correctly you will be able to see the M3P file and explosion icon - and if you get the option then install as administrator).

Once a servo has power it should hold it’s position. I would be inclined to use a brake which is automatically released when the servo is powered and applied once the servo power is removed (perhaps something like a spring loaded electromagnetic clutch).

It is probably best if you ask the question on the Warp9 forum;   http://www.warp9td.com/index.php/kunena/recent

The information relating to your question is here;

Thanks for the kind words - that's the first thing I seem to have got right this week. 

Seriously though, I am pleased that you are on your way to getting everything working as it should.

Mach4 General Discussion / Re: Mach4 5-axis

« on: August 20, 2016, 07:39:35 AM »

I have also seen 5 axis, using Mach3, demonstrated in a number of YouTube video’s but, in my opinion, it has not yet been independently proven to be sound.

The way (as Steve has said) has, I think, been demonstrated by Richard in this thread; http://www.machsupport.com/forum/index.php/topic,32107.0.html

In the folder / file ;  C:\ Mach3 / macros / Mach3Mill / m4.m1s

Add the line   ActivateSignal(OUTPUT4)   or whatever Output#  you require – calling M4 will then activate the Output# defined in Spindle Setup and the Output# you have chosen here.

Obviously a similar procedure may be necessary for turning it off.

General Mach Discussion / Re: change of axis direction

« on: August 20, 2016, 05:03:47 AM »

If you change the direction low active state for any axis it will change it's direction of travel (assuming the axis does in fact move in both directions).

General Mach Discussion / Re: Mach 3 Display not showing G Code anymore

« on: August 19, 2016, 10:43:21 AM »

I know nothing of your Custom Piece but G90.1 will place Mach3 into Absolute mode when it comes to reproducing arcs.

Different CAD/CAM software may use one of two different methods for defining and producing the Gcode for arcs - some prefer Incremental whilst others prefer Absolute. If arcs are used within a Gcode file the appropriate G91.1 / G90.1 should always be specified but unfortunately, some post-processors do not do this and confusion is created within Mach3 (the common cause of the crop circles).
