Very nice job tjstamp.

( I wish my first job had turned out as nice as yours  )

Share Your GCode / Re: He's just a Wile and crazy guy!

Hi John,

If you place a G21 at the start of the code then it will run in metric units. Then use the X and Y Scale DRO's to scale the image to the size you require.

The .nc file extention will load OK into Mach (select all file types) or, by all means, change the extension to .tap or .txt as you prefer.

You need to change your IJ Mode to the opposite of what you currently have set (Config ; General Config ; IJ Mode)

Hope this helps, Sawdust will soon be everywhere

Hi Fountaine,

1) Within Mach3, Motor Tuning check that your steps per unit are correct for each axis. http://www.machsupport.com/forum/index.php/topic,16315.0.html

2) In the Diagnostics tab, bottom left - 'Toolpath on/off' toggles the screen display.

LazyCam (Beta) / Re: Picture to Preudo 3D Engraving

« on: June 08, 2012, 11:09:19 AM »

Hi Alexus,

Sounds like you did not set the cutting depth correctly - check out the LazyCam tutorial, this should explain everything you need to know. http://www.machsupport.com/forum/index.php/topic,12078.0.html

Although I still use LazyCam, I mostly use VCarve Pro nowadays (around $600) http://www.vectric.com/WebSite/Vectric/vcp/vcp_index.htm

There is a trial version download on their website so you can evaluate it's capabilities.

G-Code, CAD, and CAM discussions / Re: Can't get M11P1/M10P1 and E1P0/E1P1 commands to work

« on: June 08, 2012, 07:11:00 AM »

Hi Jii,

The M11P1 / M10P1 (and the E commands) are only activated coincident with axis movement.

For example....

M11P1
G01 X10
M10P1
G01 X0

Hope this helps.

I made this more than 15 years ago for a different sort of application but something similar may suite your needs.  http://www.machsupport.com/forum/index.php/topic,21718.0.html

General Mach Discussion / Re: motor steping

Just a thought but if your controller has microstepping are both the X and Y drivers set to the same value of microsteps ??

General Mach Discussion / Re: Cnc code for laser switching

Never thought of  treating the laser power adjustment as a  toolchange, but it must get very tiring when you run a big project.

Hi Andre,

Like all things, there are advantages / disadvantages but you will find that laser output power will vary with tube temperature (I only cool the tube to ambient) so power adjustments are necessary from one day to the next for me.

General Mach Discussion / Re: mach3 setting problem

Hi  CNCexplorer,

With a 0.9 deg. stepper direct driving a 13 t.p.i screw you would require 204.7244 steps per millimetre. Perhaps reduce your Velocity and Acceleration to say V=1000 mm/min and A=400mm/min and see if that helps. You could also try selecting the Sherline Half Pulse Mode in Ports & Pins and see if that makes any difference.

I realise the pic shows your prototype but you will be getting varying torque requirements from that build so you should not be expecting too much in the way of accuracy and repeatability
