General Mach Discussion / Re: wierd thing with motor movements
« on: January 19, 2020, 01:47:37 AM »
It's not really that weird.

With your 'steps per unit' setup 0.0050 is your step size and Mach3 will not attempt to make a movement which is smaller than your step size. Essentially 0.0000 and <0.0050 is the same dimension as far as your machine is concerned and that is the way Mach3 is interpreting it.

Hi Victor,

I have every confidence in your ability.
I look forward to seeing some pics of the things you make with your laser.

Something I forgot to mention...

You also need to disconnect the P17 jumper on the breakout board (if it is connected).

Hi Mattceng,

Thanks for taking the time and posting your solution to the problem (and confirming the Exflueger solution).

Information such as this is always helpful for others that follow.

Hi Cad cam man,

It would be helpful for easy viewing if you would resize your pictures to 800 x 600 before posting. This thread refers; https://www.machsupport.com/forum/index.php?topic=24585.0

Many thanks,

I would be interested to know if there is a solution to this as my timer does exactly the same thing.  :(

Hi,

I am assuming you have your laser power supply wired as the diagram (with WP connected to GND through the water flow sensor). Connect the laser TTL(L) and GND to your breakout board. Configure Mach3 to set Output#1 to Pin17 (Active Low).

Now the Gcode;

X0
M11P1
X1

Will turn the laser ON
and the Gcode;

M10P1
X0

Will turn the laser OFF.

(The M11/M10 commands are required to be followed by an axis movement – that is the only reason for the X0, X1 in the above example).


In a few weeks time, once you have this all up and running and are familiar with your laser use then you can incorporate the PWM laser power control. My suggestion for PWM control is described here; https://www.machsupport.com/forum/index.php?topic=12444.msg265104#msg265104

Hope this helps.

After you click Open Gcode File, in the lower box Files of Type, select All Files(*.*) or whatever file extension you require.

Think I've read somewhere that you need an external control for moving the different axis around. This might be info from an uninformed user so I'm unsure if I should trust it or not.

If it’s within reach you could just use the keyboard for moving the axis but it’s useful to have a hand held pendant.  ;)
