Mach4 Skipping Lines

1

I have been using this Pro60x60 for a couple of years with no issues. Recently upgraded Mach4 (hobby) to 4.2.0.5036 build 5036 which seemed fine at first.

When I do a tool change (no ATC) Mach4 stops, flashes the usual red box waiting for me to hit ‘Cycle Start’. This only happens when the previous tool is different, which is what I expect. What I don’t expect is to hit ‘Cycle Start’ confirming tool change and Mach4 skips the spindle speed and M3 command (start)…

Here is the start of the Code, from Fusion using the Avid plugin

(1061_POCKET6OVER020_DNC125LR)
(T32 D=0.125 CR=0. - ZMIN=-0.2461 - FLAT END MILL)
G90 G94 G91.1 G40 G49 G17
G20
(-ATTENTION- PROPERTY SAFE RETRACTS IS SET TO CLEARANCE HEIGHT.)
(ENSURE THE CLEARANCE HEIGHT WILL CLEAR THE PART AND OR FIXTURES.)
(RAISE THE Z-AXIS TO A SAFE HEIGHT BEFORE STARTING THE PROGRAM.)

(2D POCKET6OVER020)
T32 M6
S16000 M3
G17 G90 G94
G54
G0 Z6

G0 X0.4816 Y3.5725

M5
M30

Any help or insight would be greatly appreciated.

More insight

If I move the above code into MDI and run it, works fine.
Save this code set to a TAP or GCODE file, load it, run it… if fails.

Thanks

There were a lot of issues with the early 5000 series mach 4 releases. The one that warp9 was doing development on that they said was pretty stable as far as they knew was 5125. I’ve been using that one for several months with no issues, other than the the Gcode run time timer - they changed how it works so I had to make my own timer for run time stats.

You might want to try another version to see if that helps.

Jim,

Thanks for the reply, I stepped out and took a look and see I have the latest… on the website, machsupport.com they are showing 2.0.5036.

However went back and looked at the FTP site, and saw they had a later version: 4.2.0.5296.

I will give it a whirl tomorrow and see what happens

Thanks
Lore
