Title: 1 axis linear actuator
Post by: krsykes23 on July 22, 2021, 12:09:09 PM

I'm making a single axis linear actuator to my mitre saw and I need help with how I configure Mach3 to move the X axis by just entering the desired length in a DRO. I'm OK with designing the screen-set (draft image attached) but unsure how to actually perform the simple 'move' of the axis.

Basically, is there a simple way to perform an MDI input......for example "G0 X250", but only using a DRO?  I've seen exactly what I require done by someone but they don't say how they achieved it in Mach3.

Any assistance would be greatly appreciated.

Hi krsykes23

you could try this using MachScreen:

Set function Code “Execute Basic Script” for your buttons and add to “execution code” of every button:

Button “GO”
PosX = GetOEMDRO(800)
Code("F100 G0” & PosX)
While (IsMoving())
Sleep(100)
Wend

“Button Arrow Left”
PosX = GetOEMDRO(800)
PosX = PosX – 1.0
Code("G0 X" & PosX)
While(IsMoving())
Sleep(100)
Wend

“Button Arrow Right”
PosX = GetOEMDRO(800)
PosX = PosX + 1.0
Code("G0 X" & PosX)
While(IsMoving())
Sleep(100)
Wend

the first example sets an additional feedrate .
