I think all the information you need to know about stepper motors and their drivers is contained in the Gecko documentation here; http://www.geckodrive.com/support.html

(Basically, Torque is a function of motor Current and Speed is a function of motor Voltage. 5 volts is unlikely to produce a reasonable speed performance).

Try reducing your Acceleration in motor tuning and see if that enables more motor speed before the stall. Also reduce your Kernel speed to 25kHz (35kHz is not helping you).

if you are not using an "external motion controller" then laptops are not supported so that could be the problem.
Alternately, have you transferred your Mach3 license file to the laptop computer ? if not then your Gcode could be ending at the 500 line limit of the Demo version.

Hi JimKal,

You need to go into Config. / General Config. and change the IJ Mode.

If you then Regen. Toolpath the display will be correct and the code should run just fine.

Ideally your Gcode should contain the G90.1 or G91.1 (as appropriate) and this is perhaps a failing of your CamBam post processor.

It's your money to spend how you wish but I would not be buying a laser from a seller who does not know what he is selling or how to use (software and hardware) what he is supplying.

General Mach Discussion / Re: Upgrading to latest version of Mach 3
« on: October 05, 2016, 01:20:41 AM »
Hi Ghantos,

Screen button codes are stored in the Screenset (typically 1024.set)
Ports and Pins data is stored in the .xml file (typically <your profile>.xml)
The .xml file is stored in the Mach3 folder (as is the screen .set file)


If installing a new version of Mach3 the official word is…

1) Backup the following to the desktop, or even better, a USB drive:
•   XML(Profile) – This stores you’re settings for Mach3, if you lose it you will need to re-setup you’re ports and pins, motor tuning, etc.
•   Screensets
•   Macros/Brains
2) Download the current version of Mach3 from the Downloads & Update page.
3) Install the downloaded version; allow the install path to default to where Mach3 is installed.

WARNING: If you do not backup the files in Step 1, you will lose ALL settings and configurations.

What are the technical or performance issues with an integrated video card when running Windows 7?

It depends on the architecture of the particular computer (some will work OK whilst others will not – thus the recommendation by NFS) but the most common issue, I have found, is program flow (freezing) when running long Gcode files.

Hi Alan,

This question has come up before but I have not been able to find the relevant post.

I don't think you can download the video's - they have to be watched on-line.

General Mach Discussion / Re: Z axis off, can't resolve the problem.
« on: October 03, 2016, 01:54:19 AM »
Set Z zero and the cutter to be the top surface of the work then run your Gcode file again. Assuming the cut depth is wrong then if the Z axis is jogged (or MDI) to zero does the cutter still touch the surface of the work ??

Hi Ken,

Welcome to the forum.

When you purchase a Chinese machine it is most unlikely to be supplied with a genuine Mach3 license.

I have no idea why your screen has boxes across the top, it is not a license issue.

Rename your Mach3 folder to Mach3 backup (or something similar).
Download and install a fresh copy of Mach3 http://www.machsupport.com/software/mach3/
Copy the <your profile> .xml file from the backup to your new Mach3 folder.

Mach3 should then work correctly.
