General Mach Discussion / Re: Having a few issues with Mach

« on: March 27, 2011, 07:07:47 PM »

Yeah I really only need two ranges, fast and continuous, and small steps so I just keep in in step and use shift to override it into continuous which works well for me.  I wish there was a way to get rid of the 1.000 step, I never use that one and am always paranoid that I'll accidentally have it set there and break my probe with a large move. The arrow keys I'm using are not in the num pad, in fact my keyboard doesn't even have a num pad.  I'm not convinced it is a hardware problem yet because it worked perfectly a week ago.  I'm going to change the batteries on my keyboard and see if that helps (although it seems to work fine in all other applications).

Whoa that is weird, I've never messed with the X axis input signals I don't know how that got disabled but I check it later on the machine to see if it fixes that problems.

I didn't explain the jogging issue well enough.  I keep it on Step for small positioning moves but hold the shift key down when doing long continuous moves, it steps fine but the long continuous moves are what is lagging I try to mess with this later to make sure I'm not doing something wrong.

Here is a video of some of the problems:

BTW, I meant to say the Z axis homes fine and the Y axis homes fine but the X axis does not move.

Well an odd thing is the supplied xml for the machine worked just fine when I first got it, then I started using it and all of a sudden I experienced these problems I guess about the time I started modifying my screenset.  So naturally I reverted back to the unmodified backup .xml but the problems are still there.  Attached is the unmodified backup (and is labeled with backup in the title) and the one I had been using (labeled default).

General Mach Discussion / Having a few issues with Mach

« on: March 26, 2011, 12:56:08 AM »

Here are a few of them.  If you can help me solve any of these please help, I'm a little lost.


1. When jogging, the axes continue to move for anywhere up 3 sec or so after I release the key. A few days ago this was not happening the axes stopped on a dime as soon as I released the keyboard key. Also the DRO does not change while the axes are moving anymore, they only update after the axes stop moving which did not happen before.

2. Sometimes the axes stutter and freak out making all sorts of noise (and losing steps) when doing simple moves. I can jog around at 75IPM and it's smooth, then I do a G0 move (also at 75IPM) in the MDI and BWAAAGGGAGAGHHHAGH. I have a macro which sends the Z to a tool change position and it always does that even if it is an G1 F10.

3. Somehow something has changed where when I reference all home the X axis no longer does anything the light just flips to green without the table even moving. I didn't change anything to do that that I can tell.


I can post my .XMLs if that would help

Well I confirmed that they are the right macros but they still misbehave.

I tried what you suggested and it pauses for a moment on my laptop and works correctly (as it did before adding the pause).  However it still does not work on the machine computer no matter how long I make the pause.  Could the macro be accessing the wrong database or something?  I did notice I had two macro folders of the same name one with the edited macros and one without, so I tried to delete the one with the stock macros and it wouldn't let be because it said it was in use.  So I closed Mach and deleted it fine.  Then when I reopen mach the macro folder appears again.

I think you might be on to something there.

I edited the Spiral motion output to something Mach can read by making the [spiral_Lead] R instead of Q and just using X and Y for coordinates as the wizard does.  Here is the tool path in Mach from the wizard:

Now here is the toolpath in Mach for my pocket from RhinoCAM:



As you can see the arc and helix output fine but the spiral does not.  The X and Y value for the spiral is the beginning point and end point whereas in the wizard it is divided into half circles.  The radius is applied to the entire arc instead of segments of increasing radius.  Here is the code:

Anyone know how I can get the X and Y coordinated to output half circles?

Yeah the lines that kept giving me the errors were always the first line of a spiral.  If you can think of a way around using a ton of line segments let me know.

I was thinking you mean in the post processor.  Anyway it's a bummer that the code will end up so long from the spirals but at least it works and clears up some of my confusion.  Thanks for the help.

To recap for future inquiries attached are the settings to use with RhinoCAM with incremental arcs.

Toolpath with a helix, spirals, and circular arcs:


RhinoCAM:
Output Spiral motions as linear segments checked.


Post Processor:
set arc format to Vector from Center to Start (incremental)
delete K and Q words from the block format of Spiral and helix




Mach3:
Check arc format as incremental


Here is the Gcode produced with these settings:
