Why not set them with a vernier caliper from the end of the spindle, NOT the colllet.

Hi,

This sounds a bit like running out of numbers e.g. 65536+1 =0

General Mach Discussion / Re: Home switch position

« on: April 30, 2006, 05:11:12 AM »

Hi Dave,

You can have the home position where you want, one of my mills at work has the home position on the X and Y table centre line.

The home position is only really a starting point for the control, so it knows where to start counting from.

Hi,

If I was doing this my code would look like this

G00 X.125 Y0.4           (MOVE TO FIRST HOLE)
Z1.2                            (MOVE TO SAFE RAPID)
G81 G98 Z-1.1 R0.1 F6. (START DRILL CYCLE)
X3.575                        (MOVE TO SECOND HOLE)
G80                             (CANCEL CYCLE)
G91 G28 Z0                  (GO TO HOME IN Z)
G28 X0 Y0                    (GO TO HOME IN X AND Y)
M30                             (END)

Not sure why it skips lines but the code is very odd. 

Graham.

G-Code:

N28625 X0.125 Y0.4 F6.0                        (FIRST HOLE POS)
N28630 Z0.1                                          (SHOULD BE MORE THAN .1  TO BE SAFE)
N28635 G81 X0.125 Y0.4 Z-1.1 R0.1 F6.0  (START DRILL CYCLE)
N28640 G80                                           (NOT NEEDED)
N28645 Z1.2                                          (NOT NEEDED)
N28650 X3.575                                       (NEXT HOLE POS)
N28655 Z0.1                                           (NOT NEEDED)
N28660 G81 X3.575 Y0.4 Z-1.1 R0.1 F6.0   (NOT NEEDED)
N28665 G80                                            (END CYCLE)
N28670 Z1.2                                           (NOT NEEDED)
N28675 G91 Z0 M09                                (ONLY TURNS COOLANT OFF, NO MOVEMENT)
N28680 G40 G49 G17 G80 G61 G70 G90    (NORMALLY AT THE START OF A PROGRAM)
N28685 M91001                                      (? LOOKS LIKE RUBBISH)
N28690 M30                                           (END)

General Mach Discussion / Re: Has Mach got user timers

Hi,

thanks for the ideas,  I still think a couple of timers built into mach would be a good idea, not just for lube pumps.

I would drop the accel to 50/sec/sec and work up from there, 200 sounds high to me.

It could be that the acceleration needs turning up a bit i.e. give it longer to accelerate.

or

Have you got belt slip?

Hi,

is it always 4mm out?

is 4mm 1 pitch of the screw?

is it belt driven on the axis?

are you doing lots of small rapid moves?

General Mach Discussion / Has Mach got user timers

« on: April 29, 2006, 04:36:24 AM »

Hi,

I have looked in the Mach docs and can not find any reference to timers.  The thing I was looking for was some way of turning on a auto lube pump every 10 minutes for about 30 seconds.

Is there something I have missed?

Absolutly amazing!

You must do a matching Lathe set, I would feel very left out if you didn't.
