The demo version of Mach3 allows 500 lines (give or take a couple) of code plus there are a few other limitations but nothing serious (not sure about 4th axis here). As long as a GCode program is written carefully 500 lines can be a lot of program.

You really need the full cable but step and direction for 3 axis plus limit switches and PU/PD (with common ground) could amount to only 11 wires so it may be possible, but hey, second user old printer extension cables cost peanuts.

David,

You can, of course, set the individual pin out's for the DB25 within Mach3. In addition I think you will find that the Theta control (tangential steering) is handled better by Mach3 but I have never done an exact comparison with EMC2.

Please let us know how you get on with EMC2 and which CAD programs you use to create the tool-paths for your vinyl signage.

Good fortune with your project.

At last I have got a short break from the laser, acrylic profiling and can return to working with some real wood.
This relief is approx. 200mm x 150mm and was cut into a piece of Teak. The GCode was created with DeskProto from an .STL file posted on the Zone. Total machining time was about 130 minutes with a 2mm ballnose and 0.25mm stepover.

Have you tried contacting Gerber for the information ?

Understood, the pin identifications for the serial wiring to the computer will be the same for all these models (hopefully) so that should be one problem solved.

Les,

Are you saying that the Dell corrupts the GCode program with the first 150 lines or so being correct and then the remainder being corrupted and incorrect ?

Exodus,

Just one point that's important - Check that your existing steppers can be operated bipolar (that the have 4, 6 or 8 wires and NOT 5). The cheap Chinese boards are almost all designed for bipolar operation of steppers.

This attachment  is pretty typical of a single board instructions and may be of interest to you.

Good fortune with your project.

Had second thoughts about this one and deleted my earlier post.

One of the cheap, Chinese, stepper control boards would work and if you were careful in the way it was fitted then either the original or the new options could be used, as required. Something like this  http://cgi.ebay.co.uk/3-Axis-12-36V-3A-CNC-Stepper-Motor-Driver-TB6560-NEW-/250703238018?pt=UK_BOI_Industrial_Automation_Control_ET&hash=item3a5f13d382
