It look like to be in really good shape.

I'm nor worry about this project when I look at the VMC retrofit you did, it was so nice.

Modbus / Can I add an enable and disable function in the macropump

« on: April 07, 2011, 12:05:08 AM »

Would like to add this function to the macropump.

I have a switch on the pendant to put it on or off.

But if I leave it off, feed rate and spindle override are set to approx. zero.

If I turn it on, DRO's are set to the value on analog inputs.

Would like to add a switch to enable or disable the pendant in so I can use the mouse if I want.

Thanks, Jeff

Is it possible the velocity is set to one in the motor tuning.

Is it the same for all axes.

General Mach Discussion / Pulse frequency variation

« on: April 06, 2011, 03:37:14 AM »

Look at pictures and tell me what you think. Look at the pulse frequency DRO.

Every 1 or 2 seconds, the frequency oscillate between these values, very strange but since some time, I get used to strange things with Mach3

It goes from one value to the next in a regular sequence , like I said, every one or so second.

No other software are running.

For me, home switches should be on the right of the machine.

When the machine is at home, it should be to the far right.

When machining, X Axis should read negative numbers, and going to the left


The arrow on the picture show the position where home switch should be and the machine at Zero Home Position

You can execute the code from anywhere, home is OK.

The machine always know where it is so depending on your Gcode, the machine will go where the offset(G54, G55...) is.

You need the machine to be at Zero (Home) and you need to set the Zero of the workpiece(WCS) or work coordinate system. This is G54, G55, G56 or G57..

If you hit the TAB key on your keyboard, you will see in which direction the arrows are pointing X+ will move to the right and X- will move the tool to the left.

This is always in relation with the tool.

So if the machine is at Home, when you hit start, the tool will go in the - direction, like X-20.000.

Can you post details of the breakout board your using.

In the home/motor and soft limits menu, be sure to check Auto Zero

Is your machine is similar the the one on the picture.

Are the switches for X axis wired in series

Same for the Y axis like the attached picture.

In the input tab of the ports and pins menu, both switches for the X axis must be setup as the same pin number.

Same thing for the Y axis

Try to use the automated setup pin to enter pin number, very easy to do.

Could you post a video or pictures to better explain what is you problem or even a hand drawing cad would be helpful.

Do you zero your axes when they are at home.

You probably loose steps, what happen if you decrease velocity in the motor tuning. 

Try to run the same program but at half the speed.

does it do the same thing when you jog or only when running program.

Brains Development / Re: Is this possible to do?

I have no idea if this can work of if they're errors in it but I just give it try for fun.

You probably have to do some modifications to that brain.

General Mach Discussion / Re: Spindle and Limit switch

« on: April 03, 2011, 04:23:24 PM »

Do you see the led in the diagnostic page.


How close are the Z home switch and the Z++ switch from each other.

Does it trigger at the moment you start the spindle.

I've seen it when the spindle start, there was a very very little movement of the head, enough to trigger the limit switch.

The point where the switch is open or close when homing is maybe 1/1000 of an inch so already had this problem before.
