setup a brain that maps all the jog buttons to a user led, say 1010. on your vb you can do something about it, i'm sure.

a = getuserLED(1010)

if (a = 0) then..
else..
end if

Thank you for the indirect guidance, Ger & Hood! I was using the default Mach3 steps per unit to perform the test. Thank you!

Quick update: Changing the units to mm does not improve. =(

The M990 looks like this:

Dim XPos,YPos,ZPos

Call Sleep(100)

XPos = getOEMDRO(800)
YPos = getOEMDRO(801)

SetUserDRO(1740,XPos)
SetUserDRO(1741,YPos)

End

I'm running it in inches, and I'm running the program in single block mode. So it saves during idle.

I was about to convert a traditional mill into a Mach3 CNC based Drill, very identical to Mach3's User Manual Cover picture. Although I've been successfully operating a plasma cutter with Mach3, plasma cutter does not require 4 decimal accuracy. So I did a simple test, after each G-Code positioning occurs there will be a M990 macro that saves the current X and current Y axis value.

On the G-code side, ive written:

X4.0000 Y4.0000
M990
X104.0000
M990
X204.0000
M990
X304.0000
M990

With the saved values, they all end up as:
X3.9878 Y3.9879
X103.9878 Y3.9878
X203.9878 Y3.9878
X303.9878 Y3.9878

With positioning error of 0.0122 (4-3.9878), how can I achieve the correct positioning accuracy? Are there any special techniques for configuring Mach3 to achieve 4.0000?

Thank you in advance for guidance.

Making a printer port as Plugin is fine, but don't waste the whole thing away. Printer port support has to remain, because many of the users make use of old or second handed PCs to run Mach3.

i have a standard wiimote, how do you connect it to the PC, since the wimote is IR-based?

how much do you charge for the mach licensing system?

lets say i want to sell a customized screen. no plugins, just screens vb embedded buttons.

how can i prevent people from disclosing my vb scripts?

VB and the development of wizards / Re: Digital Z Axis Control Questions

In what condition the home limit switch will be activated? when the pneumatic cylinder retracts?

if the bottom limit switch is activated, do you want it to retract instantly?

you see, pneumatic cylinders only have 1 stroke action, and usually the pneumatic cylinders will stroke out the maximum, which is very possible to hit the bottom limit switch. if it happens, you will see the pneumatic cylinders stroking up and down. @@
