Just an idea...

I would make a secure backup copy of my Mach3 folder.
Delete the existing Mach3 folder from drive C: then re-install Mach3 (version 0.62).
Copy my old <profile> .xml file from the backup to the new install. (if you have any special screens or macro's then copy them over as well).

The other issue is with Mill Wizard.  Purchased last ~August, but unusable because it will not accept the key supplied.  I've given up trying to get a new key or advice on what to do.

Hi Louis,

Mill Wizard is a supported product - please contact Mach Support to get this issue resolved. http://www.machsupport.com/support/

Hi Spandex,

I think Dan13 has summed it up well.

The first one was created from a ‘dithered’ image (which creates the illusion of shade by varying the density of individual dots) and this is the most common form of laser image reproduction. It is easy to do and it is quick.
Generally a specialist software (such as PhotoGrav) is used to create the 1 bit  ‘dithered’ image which is then sized and adjusted to match the d.p.i resolution of the particular laser being used. I used 200 d.p.i. here as it is usual to limit the image resolution to 200 or 300 d.p.i  (there is little point in specifying a smaller pixel size than the laser is actually capable of reproducing).

There are a few of us who are interested in producing true 8 bit gray-scale images (as the second picture) but it is not so easy to do as different materials react to the laser in different ways and the production time is much longer.

As he previously mentioned, Art is currently building a galvo scanning system which can work at much higher axis feed-rates than standard linear systems such as mine and I am eagerly awaiting the results of his initial tests before I start on building something similar.

The third image is very much ‘work in progress’ as it is probably the best of the three but it needs far more contrast - who knows, perhaps one day I will succeed.

Re-calibrate your machine.

Use the Set Steps per Unit calibration feature (Settings page) - follow the on-screen instructions using the largest measurement distances you can.

The simplest solution may be to just obtain a new PCI parallel port card that outputs 5Volt TTL signals. This thread may help https://www.machsupport.com/forum/index.php/topic,34848.0.html

Connect a multimeter between an axis Direction Pin and GND. When jogging that axis in one direction you should get approx. 5Volts and in the other direction approx. 0Volts.

By the way my 6040 is a USB machine

am I in the right place?

Hi Winston Harmitt,

I have moved posts around and hopefully they are now in the right place;   http://www.machsupport.com/forum/index.php/topic,36782.0.html

I use an ESS Smooth Stepper with one machine https://warp9td.com/ and a 57CNC on another machine
https://www.poscope.com/product/pokeys57cnc/ - both have excellent support and backup.
