Hi Peter,

Your change to the M23 position in the generated code is good and makes the editing easier - the M10P1/M11P1 commands I use are specific to Mach3 ( http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29 )
I had to remove an M00 (not quite sure why it is there) and add the % character to the end of file and (because I am using a laser) remove the dwell commands but the editing is quick and easy to do and your code works extremely well.

Mach3 will run just fine on your 64 bit machine it is just the parallel port drivers which don’t work.

You are welcome to use my posted pictures (if I had known, I would have used a clean piece of stock).  :D

Mach3 under Vista / Re: Mach3 under win10
« on: December 26, 2016, 02:09:27 AM »
what type of breakout board do I need to purchase for Windows 10?

Choose the Motion Controller you are planning on using first then select a BoB that is compatible with it.

Thanks heaps - so I need to change the Mach 3 port address. Does that effect the pins settings the machine manufacturer recommends?

No.

Initially, perhaps take a look at our Video's and Tutorials here;  http://www.machsupport.com/help-learning/

Couldn’t resist trying this before meeting friends for lunch.

I had to make a few changes (some essential & some desirable) to the generated Gcode file to make it compatible with Mach3 Laser use and these were as follows:-

M00 deleted (it cannot share the same line as another command in the same modal group (M23) and it is not really necessary).
G4 P100 deleted (a plasma start delay is not necessary for CO2 laser).
G91.1 added (to ensure Incremental Arcs mode).
G21 added (to ensure operation in metric units).
F600 added at start of file (a feed-rate must be specified for feed-rate moves).
M22 replaced with M11P1 (laser on).
M23 deleted (laser off must be followed by an axis movement).
G00 replaced with G00 M10P1 (turns laser off prior to rapid moves).
% added at end of file (all files must end with a Carriage Return and a null character forces the CR).

Haven’t actually cut any yet but this was laser drawn at low power on a spoil board just to verify the code.

You have indeed produced an excellent piece of software my friend.

Hi Peter,

Thank you for posting the link your free online CAD/CAM software which looks most interesting.

I think there are perhaps one or two changes which may need to be made to make it more Mach3 / Mach4 friendly and I will post more details once I have tested the generated code on my machine.

FAQs / Re: Sample gcode need larger scale
« on: December 24, 2016, 02:01:44 AM »
The issue my be that some Gcode has been prepared in Imperial units and some Gcode in Metric units and they do not contain the G20 / G21 as appropriate (this is the case with the sample Roadrunner file which was prepared in Inches but does not contain a G20 so the work comes out incredibly small on systems which have been configured in millimeters).

Hi Steve,

I am a bit concerned when you say that you have been told that WinXP cannot be loaded on your new PC. I understand that you have loaded a 32 bit version of Win7 but please check that your PC is not a 64 bit machine – if this was the case then you cannot use the parallel port with Mach3 on that PC, an external motion controller would be necessary.
(I have never tried loading a 32 bit OS onto a 64 bit PC but I am guessing that it’s possible).

From your pics the LPT parallel port address, which is entered into Mach3 for the Port #1 address is 0xE100 (Config. / Ports & Pins / Port Setup and Axis Setup).

FAQs / Re: Sample gcode need larger scale
« on: December 23, 2016, 05:33:15 AM »
Many thanks for posting the link.

Those sample files are in a compressed format (.rar) and as you have said will require software such as 7-Zip to extract the archive.

Although some of those files have .TAP, .tap and some have .nc file extensions they are all Text files just the same. When loading Gcode files into Mach3 you have the option to select the particular file extension (.tap, .nc, .ncc, .txt) or, if you prefer just select All Files(*.*).

The individual .tap files within the archive are not, in themselves, compressed so once the .rar archive has been opened / extracted no further decompression of the files is necessary.
