Yes please David. We all like pictures here and I think it goes without saying that we are only too pleased to help you if we can.

A PC power supply would be fine. Steppers are usually driven at up to 5 times or more of their rated voltage (the limiting factor would probably be the insulation breakdown voltage) what must NOT be exceeded, however, is their rated current. (The voltage is generally increased to provide more torque).

Sorry, You are or course quite right, but it is a bit like logging onto the Harbor Freight site and asking questions about Grizzly machines.

Photography is definitely not my strong point as the previous picture really does not do any justice at all to the work Mach3 is capable of producing. I have given the wood a bit of a polish - and this picture is only marginally better but it does perhaps show a bit more detail.

Hi Tim,

For my part work has intervened into my play time so I have not made any progress in a while but I should get back on it again soon.

but how would i code tangential knife in EMC2 which is what i will use.

I think this may be the wrong forum to ask that question

I agree with Rich, that's brilliant Sam. Certainly the simplest solution I have ever seen.

If Winford knew about this I bet they would have sent you the free pen without you even having to place an order.

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 ?
