General Mach Discussion / still getting softlimits warning

« on: October 20, 2008, 12:50:28 PM »

I posted about this a while back and ended up refining my mach3mill config in a number of ways, as well as the overall operation of the machine (removed table, saddle, drives, reset preload on ballscrews, cured misalignment on ballscrew supports, removed interfering material on the castings to free up another .2" of y travel, etc) and am now down to .002" or less backlash on my x and y axes. My axes are homing/zeroing in the negative direction. Machine runs witout a hiccup. Nonetheless, when I run a program that runs to within .300" or so of the y+ limit, I get a softlimit warning. I am sure of my numbers so I run it anyway, without an issue. What could be causing this? I need to be able to rely on the softlimit feature.

Agreed, the USB pendant I have just emulates keyboard input. I can simultaneously control 2 axes, one from the keyboard and one from the pendant. As it turn out, my k/b is PS/2 but I'm sure it would work just as well with 2 USB input devices.

I've had good luck with Bytecc stuff in general but looks like you may be the guinea pig on this one. Apparently it'e pretty hit-or-miss with expansion i/o cards and Mach in general. Let us know how it turns out!

Before reinstalling, save your mach3mill.xml and license file (something like mach1lic.dat).

Install an i/o card in your PC and disable the onboard LPT in CMOS setup. i/o cards are cheap.

General Mach Discussion / Re: Command to move Z-Axis -0.8500?

« on: September 27, 2008, 12:24:17 PM »

Isn't there a command operator that specifies that the position move is incremental, not absolute?

General Mach Discussion / Re: program quits at 5K line every time

Go into your Mach3 folder (usually at c:\Mach3\) and copy the mach3mill.xml file to your desktop (right click the file and click "copy", switch to the desktop, right click and click "paste"). Select the file  on the desktop and hit f2 on your keyboard so you can rename the file. Rename it mikehide.xml, then upload by clicking "additional options" when you are replying to this thread.

Line 5000 included in the post is actually the 500th line since the line #s increment by 10... if that's the number you are basing your observations on, the program has 4,499 lines.
If line 5000 is where it's stopping, sounds like a licensing issue.

I could just as easily leave it alone as it works but I am curious. I can research it and verify my suspicion without changing anything. The BOB used on my machine has screw terminals. I don't know who makes it but it is one of 3 pictured in the Mach3Mill manual on page 30, figure 4.2, the one in the lower right hand corner. Time to make some chips.
