General Mach Discussion / Maybe silly question - Feed hold or Stop

« on: February 20, 2011, 11:21:06 PM »

I have had a few scenarios where I need to stop the machine for whatever reason during a cut. Like today, my coolant got low because it clogged the line and shut off. I hit the stop button, the machine stopped, I filled up the coolant and cleared the line. But when I hit cycle start, the machine lost its path and started cutting outside the path.


When stuff like this occurs, should the Feed hold button be used? If so, and I use it, will it pick up where it left off without crashing the part?

Is there something else I should do in this instance?

Newfangled Solutions Mach3 Wizards / Bug in Rectangle Drilling op?

« on: June 26, 2010, 03:59:50 PM »

 

I was doing a simple drilling op on a plate and didn't need to cad it out. So I used Newfangled to get the holes drilled. I found that the program is not spitting out the numbers it should. I have posted below the images of my settings, and also the Gcode that it put out.

In the most sever case, it is placing + numbers when it should be using - coordinates. But I also found that if you enter a different starting coordinate than 0x 0y, that it will subtract that amount from the total movement.

I have my machined set to zero on the corner of my vise jaws as a repeatable starting point. I then told newfangled where I wanted the first hole. Please see what I wanted, and then see what I got from the wizard.

Here are the screenshots of the entered data into the wizard.


I have been through this several times and it appears that if you enter any starting offsets in to the X and y coordinates at the beginning. The X always adds or subtracts for the locations of the drilling moves. And always causes them to be a + number, even if they are entered in as negative moves.

Newfangled Solutions Mach3 Wizards / Rectangle wizard not putting out feed speeds. 2.79 bug?

« on: November 22, 2008, 07:51:02 PM »

I am trying to cut 2 simple rectangles using a 1/8" tailn bit for some molex plugs.

I have gotten the coordinates right, but the plunge feed and the feed rate is the same. I have entered 10% of max for plunge, and 100% for feed (10 IPM) is what I want, but in the rectangle wizard, it isn't putting out a feed rate, just a plunge feed of 1. Am I missing something?

Also, is there a prefered screen size for newfangled, there are a few wizards that have boxes covered by buttons and the 2.79 label is inside a title bar once a wizard is selected.


Here is the code:
