Hi Peter,

Excellent work sir, your generated Gcode works just fine without any editing at all.

General Mach Discussion / Re: Strrange sound of stepper motor Mach3

« on: December 28, 2016, 01:56:50 AM »

Hi there can I have one more question?
I am running my CNC with Mach3 and there is a thing like slowing down. But when I mill PCB board its doing kind of rounded corners. Is there a way to fix this?

Thank you

Try reducing your Velocity settings and increasing your Acceleration settings in Motor Tuning (remember to save the changes for each axis). It's bit of a balancing act to get it just right.

As an alternative try running in Exact Stop mode.

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).

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).
