General Mach Discussion / Re: Mach 3 Laser config

« on: December 03, 2014, 02:19:44 AM »

Hi Hydro,

I am pleased to hear you have it all running.

Assuming you have home switches you can reference all home then apply the offset to position all axes to the desired position – the Mach3 manual has details of how this is achieved. http://www.machsupport.com/help-learning/product-manuals/

Having said that, I find the easiest (and quickest) way is to make a mechanical template (the dimension between the Z axis and surface of the work) then just use this to set the focus with relation to different thicknesses of work.

Hi SW,

Welcome to the forum.

The Mach3 manual is probably a good place to start http://www.machsupport.com/help-learning/product-manuals/
There is also some more detailed information on the Gecko site here http://www.geckodrive.com/support.html

Hope this helps,

General Mach Discussion / Re: Z axis not repeatable

« on: December 02, 2014, 02:24:11 AM »

Hi Tim,

It is not a rounding error.

Assuming your cutter is secure and not moving in the collet...

Because +Z (upward) moves are usually G00 changing the Feed-rate will have little or no effect on the problem (as you have discovered) the issue usually relates to lost steps. Try reducing your Velocity and Acceleration settings for the Z axis (in motor tuning) by 50% and save the changes. If this cures the problem you could then experiment with the Z axis motor tuning until you achieve the best balance (the Mach3 manual's section on motor tuning refers).

Hi KJ,

Welcome to the forum.

Not really sure why you are having the problem.

Your Mach3 license should be named   Mach1Lic.dat  and this is copied into the Mach3 folder. When Mach3 is restarted it should then show your name as Licensed To:

Hi SolarImages,

Welcome to the forum.

The Artcam Post Processor you select and use just creates and lets you save the right flavor of Gcode so it is fully understood by Mach3.

Certainly having more than your fair share of problems John.

Could be that your Z axis is losing steps on the way up and thus goes deeper into the work on the way down.
Try halving the velocity and acceleration settings for the Z axis in motor tuning (save the changes) - see if this resolves the issue.

Hi Max,

This is what I use     b = Atn(X1pos/Y1pos)*(180/(4*Atn(1)))  but you have to be prepared to change the sign if moving into different quadrants.
