Have you tried using the Standard button call DoButton (27)

or

Code ("G91 G28 C0")
While IsMoving()
  Sleep(25)

General Mach Discussion / Re: Mach3 - WCS - Shows parts but cuts the first one in preview

« on: June 22, 2021, 09:33:56 PM »

What you are seeing is a flaw in the old Mach3 software its only the display driver that shows wrong the machine will cut it correctly, Mach4 shows thing correctly.

Not working in what way, what setup have you got, do you have spindle feed back, what code are you using?

General Mach Discussion / Re: Mach3 Turn - Use Y-axis to set tool height (turning on a 3 axis mill)

« on: May 30, 2021, 09:00:24 PM »

You could do a G52 Yyyyy where yyyy is the offset, at the end of that tool you would then do a G52 Y0.

E.g.

N1 (Rough Turn)
T0101
G52 Y1.5
G00 G90 Y0
(do the rest of the cuts)
...
G52 Y0
G00 X200. Y0 Z150.
T0100
M1

It sounds like noise from the pump motor or the relays switching the motor.

I ended up using win7 pro because I could not get a reliable machine on windows 10, I run on an old atom based machine now and no problems.

Try this version of the code, read the comments first.

Where did you get the code below from?

VB and the development of wizards / Re: How to zero Z after tool change in rotary setup

« on: May 03, 2021, 04:35:06 PM »

In most cases the Z axis datum is on the centre line of rotation when using a 4th axis.  Then everything is programmed from this so no matter what angle the table is at the datum stays the same.

If you measure the distance from the table to the centre of the A axis in Z direction you can make yourself a steel block and use it to set all your tools on.

If you have a tool setter then you tell it the material thickness is the distance from table to indexer C/L in Z.
