It could be you are loosing steps, is the Z depth shallow?

Mach4 only tells the Hicon what to do the Hicon is in control of the motors so my guess is you need to correct the config in the Hicon

Load the macro into the Mach3 editor and single step it through to find the error.

You may need to pre set the tool numbers in the code for it to work.

Have you purchased new stepper drivers too because the old board had them built in.

You are probably missing an end of line at the end of the code try starting and ending the code with a %

%
#1=-0.1
#2=1
#3=0
#4=60
G20 G40 G80 G90 G00
Z1.1
G1 F60
G1Z[#2]
(Calling sub O125)
M98 P125 Q5 (Repeat 5 times)
G00 Z1
G0A0
M30 (end program)

O124 (this is a sub)
G1 X0Z[#2] F60
#2=[#2+#1] (Step decrease Z by value of #1)
G1 Z1
G1 X6
M99

O125 (this is a sub)
(Call Sub O124)

VB and the development of wizards / Re: Macro to carry Z offset through multiple G codes

« on: December 02, 2020, 01:18:27 PM »

Forget the G55 and the others, set G54 to a fixed place on the fixture and then use G52 to provide a local offset for each part.

This way you program one part and use the code in subs to do the other parts with G52 set to the fixture point of the other parts.

Example

You have 6 parts set out on a 3 x 2 grid about 50mm pitch we have 3 tools, T1 spot drill, T2 5mm drill, T3 M6 tap

Datum is X & Y rear right corner, Z face of fixture, part finished height from fixture is 10.00MM

So here is some of the best free code you will ever get.

The output on screen in Mach3 could be messed up but will work just fine,  in Mach4 it should be perfect.

The cutter comp only works if the tool radius is smaller than the smallest radius on the part.

General Mach Discussion / Re: 4th axis setup

« on: November 28, 2020, 10:06:35 PM »

Yes you can enter the amount you want the home offset by and then zero will be in the plane you set.

So home the A axis, clock the table level, then enter the offset in the home off dro, you might have to set it the opposite sign depending on your set up.  e.g. swap + and - if it goes the wrong way after a re-home.

The X axis works in Diameter unless you have it set to radius mode, most lathes work be in diameter as do lathe CAM systems.
