You need to set up and output to control your spindle relay in Config, ports and pins, spindle set up.  Then you need to set up the output to the port and pin you have it wired to in Mach.

Welcome to the forum malco.

Mach3 will run almost any type of machine, the real question is how much of
a retrofit is required...  ;-)

Chapter 4 of the "Mach3Mill Install and Config Guide" discusses the hardware
used in a typical Mach3-controlled machine.  I would recommend reading
through that and then looking at the hardware your machine has and trying to
determine how much of a retrofit (if any) would be required.

Alan, Dave has a great suggestion, foam may be the tell all.  I would want to know where the problem is before I attacked it. I seriously doubt that Vectrics has a flaw but I wouldn't hesitate asking before I started disassembly.

That looks good Alan. I would ask Vectric. I wonder if their algorithm has a flaw.

The same cutter you used for the previous parts would be great.

Thanks,

Alan, just curious and I'm sure you have checked this already with a dial indicator but are the axis moving the proper distance when commanded to? 

Can you run the same shape only keep coming up until the walls have a little step that is absolutely vertical? Or, probably even easier............... can you cut a pocket the same shape (oval) with vertical walls for a test? Make the step down the same as your using in previous programs for step over and the step over the same as well.  Make the walls deep enough so that it takes several passes to get to the finished depth....... Maybe 1/2 inch.

Demo mode is only good for 500 lines of code.

Alan, If this is the same tool path as in the picture earlier, it seems much better after taking a very light second cut. If that is true I wonder if a third pass (very light) would get rid of all the tool marks.  If it does, I would have to agree with Gerry thinking it may be flex. With the bottom of the cut looking so good and only getting the tool marks as you get near vertical makes me wonder if the tool is chipped as RC asked. Dave has a very good suggestion as well about asking Vectrics. A video of the process would be worth a lot.

If it were a conventional head I would ask if you had trammed it.  The lines, looks to me like it is the placement of the tool and not due to cut direction, wood grain etc. Can you get a close up picture of the lines?

I have sent you a PM
