General Mach Discussion / DRO setting
« on: February 15, 2015, 10:57:05 AM »
Where do I click to make Mach3 keep the DRO settings? I shut mach3 and the DRO settings are not the same when I open. I usually have everything where I want zero or 1 inch offset from zer but when I open they seem to show some random set of numbers....


General Mach Discussion / mach3 windows 8.1 32bit install - blue screen
« on: January 25, 2015, 09:47:49 AM »
New installation of Mach3 on a newly installed Windows 8.1 32 bit computer.

I lost my Windows 7 disk and ordered an 8.1 disk. Did a fresh install and then installed Mach3 latest download. Then got blue screen of death and had to use last known good configuration to get the system to boot again.

Any help would be appreciated.

« on: September 24, 2012, 09:56:28 PM »
Hi and I would greatly appreciate some help figure out why I lose steps or that is what I think is going on with my machine.....
I have this setup

with these electronics

on X & Y I have 5 start screws and on Z I have single start screw.
during a job at some point the Z thinks zero is higher than it originally starts at. X & Y are perfect.

General Mach Discussion / help on acceleration needed please
« on: July 25, 2012, 01:49:37 PM »
I feel like an idiot at the moment. Seems like something I should already know but am unsure.
If I slow down my acceleration rates for my machine, do I need to change the # of steps at all?

Thanks -

General Mach Discussion / acceleration question
« on: February 27, 2012, 08:40:50 PM »
Hi there -

I have my machine set and on most part everything runs pretty well but I sometimes lose steps on X-axis.
Q. If I slow down my acceleration, do I need to change any other settings or will everything else be ok?


General Mach Discussion / screen coordinates
« on: July 13, 2011, 07:25:57 PM »
I have a problem with sometimes my system stops. As a quick fix - I just want to close and reopen MACH3 to have the same coordinates from when I close and re-open MACH3 back to the same position where it last stopped.

General Mach Discussion / help on steps
« on: April 09, 2011, 12:10:46 PM »
When going from single start to 5 start screws - My steps were always 2000 before, how do I know what to change it to now?

I am very happy how smooth the X & Y axis run with the new screws. I will change out the screw for the Z axis another day. Right now just want to know how to calculate my steps with the 5 start screws.

I have the FLA100 kit from

The x-axis seems to get some whipping with the screw rod. Not sure what I did wrong and how to stop it. I would appreciate any help on this problem.


General Mach Discussion / feed rate help
« on: January 31, 2011, 06:35:39 PM »
Not knowing what I am doing I burnt up my CNC controller. I then put an older cnc controller on my machine and have it working.

I am having trouble with feed rates. Attached is cross-01.zip - this is the gcode file exported from vcarve of the eternal cross approx 2 inches in diameter. I have the feed rate set to 20. Even though in Mach3 it says feed rate 20 on the screen it still going as if it were set to 100.

Also attached is my XML file for mach in ghetto-cnc.zip

Thanks -
