G'day Guys, this one has been doing my head in, I am turning timber fishing lure bodies on my machine, but for some reason small radius's are being produced tighter than they should, and larger radius's are coming out looser. The profile of the lure body is perfect, all measurements are fine it's just the radius's are wrong? Has anyone come across this before in rotary turning? Cheers Paul.

General Mach Discussion / Rotary glitch n Mach3
« on: July 12, 2016, 08:57:29 PM »
G'day Guys, trialing my 6 head rotary CNC I am just finishing up and I am having a bit of an issue, I am creating my tool paths using Deskproto for continuous rotation as I am cutting with saw blades. During the revolutions on A axis I am getting these slight jerky movements in the same spot on every turn. I thought it maybe something to do with Deskproto but when I run tool paths created in Aspire it did the same thing? If you jog A axis or even while calibrating the axis to set steps per it's not there. Has anyone come across this before? Any help greatly appreciated, cheers Paul.

General Mach Discussion / Mach3 FRO issue?
« on: June 17, 2016, 11:14:26 AM »
G'day Guys, I am sure it is in the manual somewhere but i can't find it  ::) When I try to change the percentage in the FRO it changes on the screen both lower and higher, but not physically on the machine, also my "Shift" key isn't changing the speed? Any tips would be greatly appreciated, cheers Paul.

General Mach Discussion / 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

General Mach Discussion / Z Axis height limit.
« on: October 09, 2012, 02:22:07 AM »
G'day Guys, I have a Romaxx WD 1 router and I was wondering how to change how far the Z Axis travelled up upon the start of the cut? When I zero everything at the moment and start to run the program the Z axis travels about an inch up before going to its start point, normally no big deal but I am cutting some thicker guitar bodies and have run into my upper limits a few times, is this adjusted through Mach3? Any help much appreciated, cheers Paul

General Mach Discussion / New to CNC
« on: June 14, 2011, 07:21:43 PM »
G'day Guys
                          I have just purchased a Romaxx WD-1 CNC router, I am using Vectric Cut3D and Cut2D for my CAM programs and Mach3 for post processing. I am having a problem with the G codes generated. When I load the G code into Mach3 it shows (a guitar body) the object much bigger than it actually is, and if try to run it is also much bigger than it should be? Please be gentle with me, as I am CNC virgin. Also when I got the machine the sample files supplied were correct size when cut, now they are massive and would not fit on the machine. I did switch Mach3 to metric "mm" as I work in metric which is probably why the sample files no longer work, the new files are in metric though and still are way too big, thanks in advance, Cheers Paul.
