This was just what it needed.  Thanks!

YOU would  set the Rapid down in config motor tuning Z lower the vel number. THAT is what limits your top rapid speed.

Thanks everyone.  I see now, the shift does override.  I like the idea of slowing down the jog, then toggling, but the mouse in my setup isn't the best.  I started with in on a shelf with my KB, but it was stressing my wrist.  So I bought a wireless mouse, then just set it on the table to use it, then move it to the side when I start the program.  So I do KB commands as much as possible.  I'll probably live with the fast jog on the shift.  It worked pretty well today.  I ran the machine a lot.

The question about feedrate, jog and rapid is correct, I was getting them mixed up.  I thin the feedrate is set in the g-code.   It would be nice to dial the rapid down.  Is that a separate adjustment?  Its only moving down a couple inches, so there is no rush.

This is a nice technique.  I'd still like to slow the Z-jog speed down though.  I had a Z-plunge that messed up a piece.  Its just sooo fast.  In the menu that pops up with the tab, I turned everything down to 50%, but its still going fast.  Is there another place?

Another question that sort of relates.  I use this setup to make guitar bodies.  I use a fixture from the front and one for the back.  The front is pretty forgiving, so long as I run all the front programs in one session.  The back needs to be pretty accurate.  My machine give inconsistent ref-homes.  They are close, but not close enough.  So I drilled a couple holes in the fixture with a .5 inch bit and marked them.  Then I try to line up the .5 bit in the hole, then adjust the offsets until its right on.

With the jog going to .005, its a lot easier to get it lined up.  But is there a better way? 

Terry didn’t mention it, but when jog is in step mode, you can press the shift key and then the page down and the Z will rapid. When the tool gets close to the work let off the page down to stop it, then tap it to move incrementally to touch off.  Works great.
HTH,

I just got my Mach3 install finally running.  I learned to use my machine on Mach2.  I did some basic cuts in Mach3, but need some help making it user friendly.

The first thing is, how do i make the Z-axis jog more touch sensitive?  That may not be the right word, but I use that to set the tool on the wood surface.  Its just way too jumpy.  I slowed down the jog speed to 60%, but that doesn't seen to make the jog go just a little with a bump of the page down.

LazyCam (Beta) / Re: 3d radius?
« on: May 22, 2011, 04:35:44 PM »
For the couple things I need to do, this might be the easiest way to go.

That aside, is there an easy (and cheap) CAM program that would be good for adding some radius cuts.   

You could generate the code by doing multiple offsets and applying the proper associated cut depth for each offset.
Much easier to have a program that does that for you.

LazyCam (Beta) / 3d radius?
« on: May 19, 2011, 07:53:39 AM »
Can Lazy CAM make a radius on the edge of piece I cut?  I'm not sure the buzzwords, but I think its a fillet or a 3d radius.  I'm pretty sure it can only do very basic 2d stuff, but I thought I'd ask.

Thanks.  I see it now.  I'll try the 1.5823. 

I have 20-30 programs that I inherited that use the 1.7323 as the top of the material.  I would much rather have that as zero, since I type that number in every time I change bits, which is 10 times or so per piece.  I think I can just use the global offset, which I use for the two fixture locations I have anyhow.  It would be easy to add a Z.  I'll play around with the G52 as well.  I'm doing little nips and tucks to make all the programs a bit more user friendly.

I made a new simple trace to make a cut out mount a plastic cover.  If I set the cut start to zero, and the depth to -0.15, it work as planned.  However, all the other programs on this piece have a start height of 1.7323.  I'd like to paste this into another program, so I need to match that.  If I change the cut start to 1.7323 (or 1, or anything else), the dept goes right to -0.25.  I even tried tricking LC by making a tool with a max dept of -.15, but it still cuts to -0.25. 

Any ideas?  I have read the manual and looked for bugs, but I didn't see any.

General Mach Discussion / Re: Lost keyboard control in Mach 2 - help
« on: March 30, 2011, 09:06:27 AM »
I was wondering whether they would co-exist.  I think I'll start the move.  The only thing I'm missing is when LazyCam creates arcs.  Those choke Mach2.  I have Mach 3 on my notebook for testing, so i know the look and feel.  Thanks.

Got it.  Many, many thanks.  The % was set to 1%.  I don't recall doing anything to start this.  I was just changing tools last night and then a no go.  I found other cool stuff while poking around - like loading my offsets from a fixture, so its all good.  The buzzwords are dialing in.

BTW, I know I should switch to Mach3, but I'm afraid to since this machine works as it is.  This is how I bough it.  Is there much to fear in the switch?
