General Mach Discussion / Spindle direction control
« on: June 08, 2007, 04:12:17 PM »
I am trying to set up my *second* digispeedXL spindle control card.
My first ran OK except M3/M4 did not change the spindle direction which was clockwise.
I thought I had a faulty card so obtained a second card.
This time it rotates CCW with the same setup BUT again direcction cannot be changed with M3/M4

On checking using the Digispeed Manual  setup routine I find that M3/M4 is not effecting the direction LED.
l
I am using Mach3 v2.064 and a Xylotex card.
I cannot spot a wiring or config fault.
Can anyone point me in the right direction to correct this fault.

Brian, thanks for your reply.
I switched off PID and spindle control was back to normal.

Attaching .XML file for your perusal

Keep up the good work

General Mach Discussion / Spindle speed problem
« on: May 10, 2007, 02:02:07 PM »
Since I last used my mill something has changed and speed control of the spindle speed has been lost.
I am using mach3 v2.064, a digispeed XL control board with spindle speed fed back using a pulse index board from CNC4PC.
 If I give M3   and a S~ codees the spindle surgeees into life then settles back to minimum speed.
This occurrs whatever speed I ask for eg S2000.
I have checked through all the config settings and tried some alterations but no success.
With the digispeed on manual I can turn the speed right up, no problem.
If  I use the automatic speed calibration it winds the speed way up in descrete steps.
I sometimes get the message 'PWM bumped to minimum' on the status line which seems tto cover the symptoms.

I am not sure whether or not I have upgraded to 2.064 since my last use of the mill which could mean a wrong setting but I have gone through the digispeed set-up more than once and cannot see a fault.
I am assuming it is not an electronic fault.

Can anyone suggest my next move; I am getting very frustrated.
I seem to remember having this problem before but cannot remember how I solved it.

Feature Requests / Write Wizard addition
« on: April 28, 2007, 04:28:03 PM »
The write wizard will generate text in various fonts very well and this can be imported to Lazycam easily.
To mill pockets around the letters a rectangular border needs to be drawn.
Can the facility to draw a rectangle on the LazyCam screen be added so the pocketing facility can easily used with text.

Thanks Graham.

I shall have to have a look at that.
I am thinking of Lazycam and its pocketing routine.

For interest; it would seem I mistaken the use of the 'Write' wizard.

Thanks Graham.

I had assumed it would cut around the letters with a G42 code so enabling me to get lettering raised above a machined background.
The wizard does not like the G42 code!!
It seems it's purpose is to take a pointed engraving tool and cut olong the outline of the letters giving a recessed letter on a surface.

Is there a wizard that would do what I want?

Hi  Graham.
