Just found it! :)  Was in my CAM program

Hmmm, you may be correct, I could not recall if this is set in my CAM program that generates the G code (I have looked in both Mach and CAM setups) but cannot seem to locate it in either place
I know it was a constant I set at some point in time.....but I have slept since then and forgot :)

This is the line at the beginning of the code that sets it to 0.8"


And then again at the end before it returns to the home position.

Hi Hood,

I think I mis spoke and called it Safe Z Height. It might be "Rapid Travel Height"???  I am looking for the setting that the Z axis raises up to at the beginning of the code and the height it raises to when returning to the home position at the completion of the code.

It has been some time since I set up my machine, but I would like to change the safe Z height and cannot locate where to change this setting.
Any help in pointing me in the right direction would be appreciated.

HI Tweakie,

I kick myself for not looking at the status lights on the drivers before cycling power. I had thought it would have been odd for all 3 to go out. Its likely I may never find out the cause, but was hoping others may have had some insight to this.
Thanks again for the reply.

General Mach Discussion / Code running.....machine not moving.

I encountered a problem last night on my machine that I have not run into before, and wondering if someone can shed some light on what may have gone wrong.

First off I have been using my machine for several years, and quite a lot these past few days, so it is well proven in.

I started the code last night using the "run from here", everything took off and ran fine. I checked on it about a hour later and all was still good. Came back an hour later and the machine was not moving on a three axis, yet the code was scrolling down and running.

My first thought was I lost power or blew a fuse, but all power indicators were on. recycling power to the control panel (but not the PC) appeared to fix the problem and all was good.

Any thoughts on what may have happened.

Once again thank you for your input, I really appreciate it.


General Mach Discussion / Sharp Corners VS Feed rate issues
« on: October 29, 2011, 09:20:53 AM »
While using an engraving bit on lexan, I ran into some re-welding problems. So to get a better quality of cut I increased the feed rate and that seemed to solve the problem.

However now I am seeing an issue when it approaches a 90 degree corner it begins to round off the edge instead of a producing a sharp corner.

I am assumed this is a motor acceleration issue, so I bumped up the acceleration values on the motor tuning page which greatly helped, but the corners are still rounding off a little. I am hesitant to increase the acceleration any more.

My question is this, are there settings other than the acceleration values in the motor tuning section that can help with this issue?

Thanks in advance.


General Mach Discussion / Re: Parallel Port Test Pulsing too fast

Yes, the readouts move as they should.

I know I am getting power to the motors, as I hear them "engage" when power is applied.

General Mach Discussion / Re: cumulative error

I went back to the Mach 3 version that worked previously....still getting the same pulsing too fast error.

Looks like a PC issue.  Any thoughts on if the integrated video card is the cause of this or it is simply a difference in the newer parallel port.
