General Mach Discussion / Re: Accuracy of DRO's
« on: May 20, 2008, 05:39:54 PM »
Thanks guys, I do only really notice it when I set the steps to an extremelly low number so the test is quick to sit through.

Any idea why for some reason the jog buttons (arrows on keyboard) won't work on one of my screens?
If I start Mach, enable drives, Home machine, the check Jog Enabled is On and set to either Step or Continuous, it just won't move, but if I load another screen, without changing anything else. The jogging works correctly.
I remember having this a while ago, I ended up giving up and restarting the screen, but the screen I've got now, I've been working on for about 2 months, there's ALOT of code in it.
So preferably I'd like to try to figure out how to fix it, rather than copy/paste.
Thanks.

From what I understand this is meant to help to computer run more efficiently....I think.

Is this meant to be entered into the Macropump like this....

Declare Sub Sleep Lib "Kernel32" (ByVal dwMilliseconds As Long)

or am I meant to change the dwMilliseconds to a value??

Hi Carl, I believe the newest version has fixed the problem of saving the DRO's

General Mach Discussion / Accuracy of DRO's
« on: May 11, 2008, 07:06:07 AM »
What exactly decides the accuracy of the DRO's, I've noticed when I'm making different specialised screens that because I have them on a PC (no machine interface) I have the imaginery motors cranked up really high just for testing.
I think (not real sure though) that this is why I have the following issue:
When commanded to go to X22.00 Z12.00
The actual DRO's register the following,
X21.980
Z11.978

Is there a way for me to have this to register correct and still have it moving fast?

96
Yep, spot on, is it possible?

Mach Screens / Persistent DRO's
« on: May 09, 2008, 06:15:34 PM »
I've got approx. 82 DRO's on one of my screen sets, (a lot I know).
I've noticed that after approx. the 1255 OEM code point they won't hold the values that was in them prior to restarting.
I've tried Persistent DRO's on & off, but no change.
Any idea if there is a way around this?

Also on another note, is it possible to stop it returning to the first screen when the ESTOP is cleared?

Yet again, Thanks scott, works well. Now that I look at the function Abs, I think you may of told me this once before, sorry.

Is there an easy way to always force a positive value into a DRO, I have a small calculator I've made for working out a lead (similar to a drill flute), it works great but it returns a negative value.
Is it possible to change the following line to make it always output a positive value?

SetOEMDRO (1203,3.141592654*Ø/Tan(AngleinRadians)) 'This normally works out to a negative value, but the value in a positive is correct.

VB and the development of wizards / Homing Routine ....again....
« on: May 08, 2008, 12:54:24 AM »
Hi guys,
(Before you ask, yes I did search..........probably not well enough though)
Is it possible to use the homing routine to home at 30% feedrate, then home at 5% feedrate for accuracy?

e.g
DoButton( 22 ) 'Home X at 30% feedrate
DoButton( 24 ) 'Home Z at 30% feedrate
DoButton( 25 ) 'Home A at 30% feedrate

DoButton( 22 ) 'Home X at 5% feedrate
DoButton( 24 ) 'Home Z at 5% feedrate
DoButton( 25 ) 'Home A at 5% feedrate

Thanks
Darc
