General Mach Discussion / Re: z axis gaining height with vcarve toolpath's only

« on: November 22, 2013, 05:46:59 PM »

Cut the Z axis acceleration in half. my machine acted similar when doing 3D carving, but ran fine doing 2D work. After reducing the Z accel, it's been perfect ever since.

General Mach Discussion / Re: Here's our setup - and we've got some questions

1) You really need a home switch at the top of the Z axis to use the SafeZ feature effectively. Otherwise there's no sure way for Mach3 to know where the extents of Z travel are.

2) When you have slaved axis, all settings on the COnfig >Homing/Limits screen must be set exactly the same for BOTH the master and slave axis, or the two sides will move differently.

Most of these issues sound like you're origin (Machine coordinates 0,0) is not where it's supposed to be, or possibly where your g-code thinks it is? Or, you may have one or more axis reversed. COuld also be an issue with offsets.

2) The video used a very old version of Mach3. I don't think the red outline is used in newer version of Mach3.

3) The lower left corner should be X zero Y zero. Where are your home switches located? In Config>Homing Limits, "Reverse" changes axis direction, and "Home Negative" reverses homeing direction. If you're homing to 0,0, the X should home to the left, and the Y should home toward you.

4) Again, I think you have your origin set wrong/ axis reversed.

5) What do you mean you have a "safe limit" set? Do you mean soft limits? If so, do you have a limit switch at the top of the axis which sets Z zero at the top, with downaward travel being negative?

You don't have to have Machine Coordinates selected when doing Ref All. Ref All (homing) is always done in Machine Coordinates. Again, it all comes down to where your switches are, and how you have Mach3 configured to use them.
The more info you can provide, the easier it is to help.

Machscreen Screen Designer / Re: New Screen Color

« on: November 22, 2013, 07:07:04 AM »

It's a custom screenset they've developed, probably strictly for their machines.

There are many screensets available for download, or you can create your own. But you can't just change the color of an existing screenset.

Yes, you can assign hotkeys in a screen designer.

You can assign hotkeys to the DRO's, but I'm not sure if you can "tab" through them.

There are apparently bugs in Mach3 which currently prohibit any other methods.

VB and the development of wizards / Re: Tool zeroing macro help

« on: November 18, 2013, 09:05:46 AM »

The second one is not complete, and appears to be missing quite a few lines.
There's an if statement with no "end if" and the last line is an error message that should have some other code to go with it.

General Mach Discussion / Re: Setting machine Coordinates

« on: November 17, 2013, 04:41:54 PM »

1. Set my machine to a physical zero that I establish by looking at the machine on X Y Z
2. Run a code to X Y Z based on the physical zero that I've established

The work offset is throwing me off and I'm not sure how to get rid of it.

Thank you for the help,
Max

Go to the offsets page and set the offsets to zero, or, after using Ref All, press the zero X and zero Y buttons. Work coordinates are the coordinates that are used when g-code is run. If you don't want any offsets, then you must set the offsets to zero.

General Mach Discussion / Re: Confused with setting limits in Mach3

You have home switches enabled in Ports & Pins, Input pins. Disable them and you will no longer get movement when pressing Ref All.
