I'm beginning to think that my E-Stop is wired incorrectly for starters. Its wired Diagonally across the Inputs at the moment.

Your EStop should be a normally closed contact and wired between Pin 10 and GND (Pin 12).

The G90/G91 relates to Absolute/Incremental movement and the appropriate method is usually specified within the Gcode file.

The Mach3 manual has more detail and can be downloaded from here http://www.machsupport.com/help-learning/product-manuals/

« on: February 01, 2017, 01:38:09 AM »
Unfortunately your zip file did not contain the Gcode so I was unable to replicate the problem here.

Do you have a licensed version of Mach3 or are you running in Demo Mode ?

General Mach Discussion / Re: G540 Steps Per
« on: January 31, 2017, 07:44:33 AM »
Sound advise Gerry but beginners, newcomers and the inexperienced, etc.  would perhaps use (and trust) a Gecko provided .xml.
The Gecko documentation does not make it absolutely clear that Steps per Unit need to be altered according to the machine nor do they make it clear that the G540 has fixed 1/10th microstepping (which is essential information for calculating the steps per for any machine).

The Gecko products and documentation are second to none but improvements could be made to the documentation as Kolas has pointed out.

Hi Yap,

Welcome to the forum. For a first post it was pretty good but not quite in the right place.  ;)  (I have moved it to have it's own topic).

Unless your post relates to one of the existing sections it is probably best to post in 'General Mach Discussion' using the 'New Topic' button (towards top of page).

I am sure someone will be along shortly to suggest what you need to do to get your spindle running correctly.

Initially, make sure you are setting-up Mach3 in the Units (Inch/mm) you intend to use (Config. / Set Native Units).

In Members documents there is a calculator for finding Steps per Unit and also a math's example.

Which USB adapter are you using ?

Could you zip and post the problem Gcode file ?

Your guess is as good as mine - I have purchased some electronic stuff from China which is absolutely excellent and other stuff which turned out to be junk.

Solid carbide engraving bits can be purchased cheaply on the bay, depending on their quality they wear quickly and should be replaced frequently.
Beware that SS work hardens easily when engraving so the job must be kept cool (flood coolant is best) but I am sure you know this already.

The second one would be best but beware, you get what you pay for in this world, they may or may not work as well as described.
