General Mach Discussion / Re: CAM recommendation, other than CamBam

This is 2.5D really but quite a few of us made these with 3 axis machines last year.

General Mach Discussion / Re: Mach3 motion control over two LPT ports?
« on: February 20, 2011, 07:16:27 AM »
Hi Brad,

I use a seperate 'stand alone' psu and controller for my 4th axis which connects to a second PCI card configured as LPT2. Mach has no problem with sharing the tasks between ports #1 and #2.

Dan,

The glitch top left is usually caused when the object vectors are not joined (LazyCam takes the shortest route to the next vector).

What did the whole thing look like on the LazyCam screen ?
Did it show these errors ?

Hi Rick,

I worked through most if not all of the Vectric examples some while ago http://www.machsupport.com/forum/index.php/topic,6962.0.html and all the Vectric software is just so easy / quick to learn I was hooked, just needed the money  ;D

There is nothing wrong with CamBam, I have used that a lot in the past but had quite a lot of difficulty learning all it's little wrinkles. I used the free version and Danny at CNC4Free.org http://www.cnc4free.org/ was most helpful resolving problems. There is also a lot of other interesting stuff on his website if you have not seen it already.

Rick,

Don't forget about LazyCam - it's free, part of Mach and works extremely well in most instances albeit taking rather a long time with complex files.

It has taken me forever to save up for VCarve Pro. All I can say is that it is worth every penny and well worth waiting for.

Just a suggestion but some pieces of shim formed around a 5mm drill may make the necessary sleeves to fit between your motor shafts and the pulleys.

That's the spirit.
You will succeed and have the finest machine in the end.  ;)

Sorry Dan, I don't wish to cause offense, but it sounds like your build quality may be letting you down.
Unless you get the mechanics perfect (and I mean perfect) then you will not get the machine accuracy you are trying to achieve.

General Mach Discussion / Re: does mach 3 work with USB?
« on: February 17, 2011, 12:45:02 PM »
guys,
I have a driver board with parallel port and I would like to use USB, so:
is possible to use a parallel port adapter for USB connection and then use MACH4, it will work well?

The USB to Parallel port cables are intended for printers and will not work at present with Mach3.
As mentioned previously the smooth stepper will connect a USB port to driver board with 25 way cannon D connector and work with Mach3. I occasionally use the SS (with one machine only) and am very pleased with it.

Hi Dan,

I will try to answer your questions best I can.

I cut a lot of vinyl on my CNC using a drag knife with 0.5mm tip offset - the corner rounding has never been a problem.

LazyCam - top left click on 'File' where you will see that you can open HPGL and PLT files. Once they have been converted to GCode you can feed them direct to Mach3 for output to your machine or save them as a GCode file.

Target2GCode is available on the 'Majosoft' website (you will have to search for it) http://majosoft.com/ but it sounds like it is the VB runtime components that you are missing and these can be obtained from the Microsoft website http://support.microsoft.com/kb/290887
