Sounds pretty useful to me, a great idea.

ANY ideas on a Transformation matrix where you scan the material then Process the Gcode Z axis to fit the material. ? One controller I have seen has it working . The demo was impressive to say the least.

(;-) TP

How about Paul's Warp Driver http://paulrowntree.weebly.com/warpdriver.html

Excellent work Zig. 

Rigid couplings are not normally used, for various reasons. On my machine, try as I may, it was not possible to machine the motor mountings precisely square and parallel so proprietary flexible couplings allowed my steppers to run without stress.

One other point you may wish to consider is incorporating a thrust bearing between your motors and screws. The motors have dimensional tolerance during manufacture and this is usually taken care of (by the manufacturer) with the use of one or more crinkle type washers fitted behind the rear bearing. This will allow the shaft to move axially under load and may cause you problems with maintaining an accurate tool-path later on down the line.

These comments are in no way intended as a criticism, you are doing fine work with building your machine and I am sure your video’s will be of great help to others. Keep up the good work my friend.

In Config / General Config you can check E-Stop on M30 then include M30 at the end of your GCode program to preform the E-Stop.
I have never used it but G28.1 included before the M30 should home the machine to your pre-set positions (section 5.6.1 in the manual refers to setting home/soft limits).

I really don’t think that ‘RTFM’ is a reasonable response to questions asked on this forum.

Yes, they should do that but it is not their fault if they are unable to fully understand the terminology used, after all, many new members are starting at ground zero - they are here and using this forum because they wish to learn.

Anything that can make the task of helping others easier, quicker or more effective has to be good.

Just my opinion.

Hey Hey.....for each time Hood asks for an xml file I put a penny in the jar towards his retirement. For each time one is not posted or it's asked where to find it i remove a penny. So far he will need to work till year 3013.

Hi Guys,

Although it was my original intention to make this an ‘open source’ project for anyone to construct, commercial interest was shown. They took their time deciding but following a reasonable offer I have now sold the design.

My curiosity prompts me to ask .. Why?

Some of the unscrupulous CNC controller suppliers are shipping their product together with a Pirate Mach3 license.

It is not, in my opinion, unreasonable for Artsoft to incorporate measures within Mach3 to protect their investment against such Piracy - thus the problems giacc is experiencing whilst using a Pirate license.

Nice work Dave, she will be pleased with that. 

(This halftone technique looks perfect at a distance then as you get closer and closer it gets harder to believe that there is actually a picture there at all.
The software is just brilliant for creating display / exhibition work and the results certainly get some attention from the visitors. 10 out of 10 to Jason).
