This can be caused by a corruption to the .xml file. Try Operator / Restore Settings and roll back to an earlier time (before the problem occurred).

Tangent Corner / Thread views.

Just flicking through the forum pages today I spotted the number of views on my laser project thread at 666,666.
If we went back a few hundred years I wonder what Matthew Hopkins would have made of that number ?

General Mach Discussion / Re: GoTo Zero not working

I dont think the speed is set too high.

As Craig has said your Velocity / Acceleration settings are set too high for your machine as it stands.

As I explained above: Jogging works perfect. Ref All Home works perfect and a G0 (after a M3) also works perfect.

Just a guess but what I think you are finding here is a Mach3 peculiarity or limitation relating to the blended axis velocity of the Go To Zero function.

I know that one day everything will be controlled by our phone (albeit bearing a different name) but until that day comes I will, and I urge others to, continue using a dedicated PC for controlling what could be an extremely powerful CNC machine / laser etc.

FAQs / Re: posting problem

« on: April 14, 2018, 02:01:35 AM »

I have mastercam x4 when I post a file and load it into mach3 some of the radius on the part are converted into very large arcs unlike the drawing . I double checked the drawing in mastercam and back plot  and it is right but when it gets to Mach3 the radius's not all of them but some of them are changed . has anyone else had this problem and what can I do to fix it ?

I have recently contacted Mastercam regarding their latest Post Processor for Mach3 / Mach4 and their response was to say the least disappointing. Others may have better luck but don’t hold your breath whilst waiting for anything helpful.

Mach3 handles arcs in both Absolute and Incremental Modes and to avoid confusion it’s Gcode should always contain the G90.1 or G91.1 (as appropriate). It is usually the job of the CAM Post Processor to insert these commands but Mastercam does not really bother with Mach so the commands are omitted from their p.p.

You can correct the situation by changing the IJ Mode (Config. / General Config.).  The IJ Mode is a modal setting and once changed will remain but to be certain of avoiding future problems it would be best to add the G90.1 or G91.1 (as appropriate) to the start of all Gcode files containing arcs. The G90.1 or G91.1 should be on a separate line at the start of the Gcode and certainly not share the same line as a G90 or G91.

Feature Requests / Re: Icons on the tool table

Hi Cad cam man,

The development of Mach3 has ceased in favour of Mach4 so no future changes will be made to the Mach3 tooltable icon display.

If you felt really adventurous you could always create your own icons and using a suitable resource editor replace the existing bitmap 371 with one of your own.

As far as I know it is what it is and cannot easily be changed.
