Mach3 Vectric Aspire Wrapping problem
« on: June 10, 2016, 06:48:09 PM »
G'day Guys, I am having some issues getting a G code to run in mach3 that was created with a Vectric Aspire Wrapping gadget. The item (a Fishing Lure Body) wraps fine in Vectric, all previews look good, but when I run the G code in Mach3 it doesn't work correctly? It would appear that "A" (my X) is turning the timber through 360mm instead of 360 degrees? I am hoping someone here has had a similar experience when setting up for rotary turning. The machine is a 6 head ground up build made just to produce timber fishing lure bodies. It jogs off the keyboard fine, with X being rotational, Y transverses the carriage and Z as normal. I loaded a simple 2D G code into it and it worked fine, as it does with my standard CNC? Also I am looking for a CAM program that will allow for "continuous rotation" the machine works in a similar manner to this machine in the Youtube video, any help would be greatly appreciated, Cheers Paul

Ok so a little more knowledge gained, I was able for the first time to see my 3D tool paths in Mach3 (found un-checked box  ::) ) What is happening is my G Code actually looks fine but I would say motor configs are way out. My rotational stepper motor should obviously revolve my chucks through 360 degrees then return as normal, but what is happening is in Mach3 I see the lure do one revolution (which takes about a minute) while my chucks do around 50 revolutions. So I guess my questions is how do I configure the 4th Axis to be in sync with Mach3? Cheers Paul.

I really have not tried this so please dont be too hard on me.

I am building my own cnc from scratch and I noticed this video on how to setup axis.

it seems you force the cnc do a predictable distance say 18 inches, then measure the actual distance and find the % error. (the bigger the number the better)

this guy explains it so much better and he has a marvellous accent :)

I understand its not a video on rotational axis but it might help as you seem to be getting the wrong results.

One last thing are you useing inches and millimeters and mixing them somehow, I suppose you may have used a another (turning) interface and it needs calibrating?

You need to set the steps/unit to the number of steps it takes to turn in 1 degree.
