General Mach Discussion / Trouble getting Mach to run anything.
« on: April 26, 2007, 02:01:32 PM »
Hey guys.
Just trying to setup a new system using Mach 3. My router machine is using an older version of Mach 3. It is working fine and running sheetcams g code without a hitch.
My trouble is getting new versions and even some of the older versions of mach 3 to run the same g code on just the computer. (New)
It gets down a few lines and stops and won't progress. I can't get the dro's to move. This is also using the ini file off my other system and the same gcode. I have been over this many times installing and uninstalling different versions and ini's and trying different codes. I am out of things to try.
Any suggestions?
Thanks a bunch in advance. I know I am overlooking something.

Here are a couple of sample codes I am trying to run.

General Mach Discussion / Setting different zero.
« on: December 30, 2006, 07:54:12 PM »
Hi all. Been a while. I ran into something today and I'm not sure how to go about implementing it. I'm not sure if it's a Mach thing or I should deal with it in Sheetcam.

I have my machine zero set 3/4" above the actual table. I have a piece of 3/4" plywood mounted to the table and it is pocketed to accept my blanks for some dado's.
I make some other parts for different things that are nested in another piece of 3/4" screwed to the first. It's not exactly 3/4" between the two zero's. it's actually .7658. Question is how can I change the zero's when I change the nesting plates? Right now I do it hit and miss. That takes awhile.
I haven't researched many of the features in either Sheetcam or Mach, but thought maybe someone could point me where to look or what to set.
Tolerances can vary about 1/64th or so in my parts.
Thanks.

General Mach Discussion / Home/Limit referencing.
« on: March 17, 2006, 01:18:17 PM »
Hey fellas.
Finally had time to get my switches wired up.
I currently have the X-- and X home wired to the same switch. I am aware how to use the soft limits, but how do I get the machine to pull off of the switch automatically to a certain point? I am not sure of the accuracy of the switch, but its the best way I have right now of setting zero at the same place on the machine every time. My Y is setup the same. The X++ and Y++ limits are shared. I would just like it to pull off too. I know I can set these to be able to jog off it. I was just wanting a way to reference.
Thanks in advance.

General Mach Discussion / Diversify?
« on: November 04, 2005, 01:06:14 PM »
Benny, I think now is the time to induce more categories and instill the current ones where they belong. I orsee this getting too big too quick to deal with. Simply a suggestion mind you. It will also help with guy s that really want to post, but don't want to intrude. The need a particular spot to post in to feel comfortable with letting the cat out of the bag. Well, I guess I feel this way.
What thinks the rest?

General Mach Discussion / Lifting Z first and always?
« on: October 27, 2005, 07:22:10 PM »
Hey fellas. The other day I was learning some things on my machine in real mode. I was just using a cheap v cutting router bit in some lexan. I had been using a straight cutter. I came to the point in my program for the tool change.
I told Mach 3 to remember where it was, then I jooged over to where zero was once I had the v cutter installed. I was wanting to change the zero. Now I know how I should do this in the future. I should have my zero up and use a negative to cut and use a block to set zero after a tool change.

My problem was that once I had the Z zeroed where I wanted it, I told it to return to where it was when the tool change started. As luck would have it, the only screw I was using to hold down that corner was directly in the path of the return to pre-toolchange. Since my z didn't lift first, Snap. It returned perfectly to where I wanted and would have been at the right height as well had the point not been snapped off.
My question. Is there a way to force Mach to raise the Z before any rapid moves?
It does this fine when running otherwise. Just kinda curious. Thanks in advance.
