Do you do an absolute return to start before the second cut ?

Tweakie, Mike,

It is now.

The screen set is provided as is, no changes will be made to it, it was done for use in schools where only the minimum amount of controls are needed and as such is great for just loading and running g-code.

With the windows menus turned off it makes it very hard to play with the settings and as such not much can go wrong. Or that is the theory, I am sure some kid will prove me wrong

Mancuza,

my advice would be stay well away from Alphacam now a days!

Hi Henry,

there is nothing in the g-code telling Mach to slow in the corners so it could be a CV setting that is causing this.

The safest thing is to put a very tiny rad on the end of any sharp point that way the tool has a clearly defined outside path, the rad can be .001" or even less but it forces the comp to stay on the same side of the line.

the only way I can think this may be possible is in the Macropump, run a check in the Macropump code to check the current position DRO and if its greater than 700 drop the speed, the down side to this is it would do it for every program that travelled over 700mm so you would have to edit it out once the job was complete.

« on: January 02, 2018, 06:27:46 PM »

Depending on what you need to do with the DRO set to zero you could look at the G52 command that sets a Local zero point as an offset from the current fixture point.

So you can move to any position, read the current location using the #vars and then use them to set the G52.

E.g.

G00 X100. Y50. Z25.
G52 X#5001 Y#5002 (Make current point zero)
(do your local work)
G52 X0 Y0 (cancel local offset)
G00 Z25.
M30

Your G54 and G92 are left unchanged but you can work at zero.

It might be a good idea to post the g-code on here (we only need the bit form start to where it hits the plate) so we can look at what is is doing and then we may have a better idea of what you need to do to fix it.

If you click on the 'Single Block' button you can then select the diagnostics tab and watch the 'Dist to go' figures. You need to press 'Cycle Start' each time to make it move to the next line of code and if you have the rapid feed override set to zero you can see the dist to go before the machine moves.

Mach4 General Discussion / Super Simple Screen Set (Mach4 Beta)

« on: August 14, 2017, 01:04:55 PM »

Here is a Mill/Router screen set for you to play with.

Anything it has not got you will NOT get.

Anything you want altering will NOT happen.

It was done for education and other than bug fixes it is what it is.

I have a Mach3 version too if anyone wants to try it.

Here is the link to the Lathe version :- https://www.machsupport.com/forum/index.php?topic=41385.0
