General Mach Discussion / Re: Spindle direction control

« on: June 09, 2007, 11:47:57 AM »

Further to my previous post I see in Mach3/macros there are 2 files M3.mls and m4.mls.
Is that where they should be?.

Hood where are the M3/M4  macros. This is them first I have heard about having to add them.
I have checked the voltage on the (pin 17) Dir signal on the Xylotex board when entering M3/M4 on the MDI screen.
The voltage stayed the same at 4.40volts so it sounds as though the problem occurs upstream of the Digispeed board.

For vmax, I have checked the pins and they seem to be as I understand the manual.

Hi Hood,
Now you've lost me.
Aren't they just part of Mach3?

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.

Good photo's Graham.
Now I know how the rowboat worked.

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.
