G-Code, CAD, and CAM discussions / Re: Need help with waterline and pencil finish using Meshcam.

« on: March 30, 2012, 04:59:58 PM »

If you don't use the same tool for all the finishing passes, you're going to have noticeable differences between those areas. I'd try a 1/16" or 1/32" ballnose for the pencil toolpath. But this can vary greatly from model to model. You might want to ask on the MeshCAM forum what bits people are using, and post some pics of your model.

General Mach Discussion / Re: Pin out for probe function

You may be able to combine home and/or limit switches to free up a pin.
You could also add another parallel port, as Hood said.

General Mach Discussion / Re: radius different one corner of square?

« on: March 27, 2012, 09:30:18 PM »

No.
CV mode is constant velocity mode.
Mach3 tries to maintain constant velocity, which means when it gets to a corner, one axis needs to start moving before the previous one stops.
In General Config, try setting the "Stop CV on angles" setting to 89 or 90.

CV mode is causing the other corners to get rounded. The best solution is to  increase acceleration. You can also try playing with the different CV settings.

To chenge the start point in V-Carve Pro.
Switch to Node edit mode. If there's an existing point that you want to make the Start point, hold the cursor over it and hit "p", and it will turn green.
If you want to create a new Start Point, hold the cursor over the spot, and hit "i" to insert a point, then "p" to make it the start.
These options are also available from the right click menu.

Sounds like your steps/unit are set wrong. Can you post some sample code and the .dxf to make sure that's not the issue?

General Mach Discussion / Re: Motor tuning window

I see this problem come up every now and then, and don't know what causes it. I think the best fix is to try uninstalling and re-installing Mach3.

General Mach Discussion / Re: Y axis help

« on: March 25, 2012, 07:57:33 AM »

Depending on how you work, you may want to try using a home offset of -11 for the Y axis in Config>Homing/Limits. This should make your Y axis Z0 in machine coordinates be the center of your table.

Sounds like your machine is set up backwards.

General Mach Discussion / Re: Mach3 parallel port drive

« on: March 24, 2012, 05:51:40 PM »

The driver does not show up under the port's properties. It's listed in Device manager under Mach3 Pulseing Engine.

Do you have a 64bit OS?
