General Mach Discussion / Re: How do G codes work and can they be changed

« on: February 13, 2007, 03:22:14 AM »

Have you thought about using a TAP-MATIC, using one of these the spindle always runs forward and it auto reverses and comes out of the hole at twice the speed.

There are quite a few posts about this on the forum, including G-Code to do it.

It sounds like a steps per issue to me,  what is the pitch of the ball screw and the ratio of the motor to the screw, also how many pulses per rev are the motors.

Hi Marco,

If you are sure your setting of the datums is correct then all I can think is that maybe you have a value in the tool length offset for offset number 3.

Also take out the bits of the code I have marked red and try again.

If you look in general config you can set the G04 delay type if its ticked its micro seconds.

What is in the height offset 1, it should have zero in the Z height.

or

Remove the lines N30 & N40 to kill the offsets.

The very early ones used paper, they rolled glue, then laid paper on top, then cut the shape out with a laser, they did this over and over again until the final shape was complete.  They also had the advantage they could make hollow shapes without supports, funny how things move on, not always for the better.

Some posts do a G97 to stop the spindle accelerating as the x axis rapids into position and then change to the G96 to do the cutting, sometimes they do it on a rapid to a tool change as well.  The G97 fixes the speed at what ever it is at the time.

Send me the post and I will sort it for you.
