Machscreen Screen Designer / Re: Feed and Spindle Bargraph with LEDs?

« on: July 04, 2013, 09:36:51 PM »

That screen on YouTube is done in Flash, and is not a standard Mach3 screenset.

I've never tried it, but I guess you could use a series of User LED's to represent your bar graph, and use brains to toggle them on/off based on rpm or feedrate.
You'd probably want to look at the DRO, and if it's greater than a certain value, turn on the LED.

I'm picturing the kid in the cell phone commercial explaining what  happens to a slow turtle in the road.

That's how comp works. It "rolls" around the corner with a radius toolpath, but your part will still have a square corner.

Could be a corrupt .xml file as well. Twice I've had strange homing issues and my backup .xml fixed them right up.

Word is that there will be an introductory price when Mach4 is released.
Noone really knows when it will be available, but a beta is supposed to be available soon, maybe a month or two?

Your g-code is probably specifying a spindle speed lower than the range of your pulley speed. Just changing your pulley speeds in Mach3 should get rid of that error message.

However, that message alone should not prevent Mach3 from running. My guess is that there may be some other errors in your g-code following the spindle speed?

Is it a plasma, or a mill?
I don't know of anyone who would come out and redo your machine, without probably charging more than you originally paid for it. You might want to look at places that sell complete ready to run kits, like http://www.candcnc.com/
Unfortunately, they have the absolute worst website in the world.

Here's an example of a homing script:

DoButton(24)
DoButton(23)
DoButton(22)
While IsMoving()
Sleep(100)
Wend
SetParam("XRefPer", GetParam("XRefPer")/10)
SetParam("YRefPer", GetParam("YRefPer")/10)
SetParam("ZRefPer", GetParam("ZRefPer")/10)
DoButton(24)
DoButton(23)
DoButton(22)
While IsMoving()
Sleep(100)
Wend
SetParam("XRefPer", GetParam("XRefPer")*10)
SetParam("YRefPer", GetParam("YRefPer")*10)
SetParam("ZRefPer", GetParam("ZRefPer")*10)

We need all the electronics that go with it also. It is a three axis cnc machine. So looking for someone to fix us up with the electronics needed to run the machine and configure Mach 3 to go with it.

Where in Michigan, and what kind of machine is this?

Works in progress / Re: "Vintage" Screen Set

1. If I press the 'Home' button after using auto tool zero, X and Y go home as they should and their DRO's show the correct coordinates.
I don't have home/limit switches on my Z axis so it stays where auto tool zero told it to go, but the DRO will change to some random number sometime.
This caused me to bury the tool in my work piece a couple of times.

When you auto Zero the Z axis, you're setting an offset for the Z axis. This offset is the position relative to machine zero for the Z axis.

Then, when you Home the Z axis, it's setting machine coordinates for the Z axis to 0. If the Z wasn't homed before running the auto zero, then most likely, your Z position will change.
Note that when you home an axis with no home switch, it will set machine zero to the current position of that axis.

The proper procedure should always be to home the machine first, then run the auto zero. Always set the axis to zero prior to running the g-code, as homing after setting zero will most likely change the zero positions.
