General Mach Discussion / Re: Mill just wanders off
« on: March 10, 2009, 08:36:53 AM »
Hi Mintz
I have thought about your suggestions and I favour the isolation transformer most, but it did lead me to the thought that it could be a grounding issue.

Thanks Jim
I had guessed it might be finger trouble.
Trouble is only using the machine occasionally doesnt help, I did read the manual but that was a while ago.
I will probably get back up to steam again as I am converting my lathe to CNC at present.
Doing the lathe seems to be more daunting than the mill from the mach 3 point of view.
From a mechanical point of view the lathe is far easier to modify than the mill and an awful lot cheaper.

The program appears to run correctly ie. after it wandered off I unloaded the program and reloaded it with no changes and it ran correctly.
So it doesnt appear to be program related and that was the same for the hole. However I had previously changed the zero position as each of the features had been set at 0,0 in autocad/dxf/D2NC, which relates to the absolute and incremental theory.
Have I just cheated?
Thanks Bill

Yes it is wandering after/during  a circular interpolation.
I am using a D2NC generated program and I dont know whether it is absolute or incremental.
But I will have a look at my settings. I think my machine is running as incremental as I reset the zero position.
Although I have made a few things I am still a bit green.

It seems to happen at the start of a sequence, it happened twice today once while cutting a 25 way d type hole it started to ramp in then carried on down the ramp line. and the same with a circle.

Whilst machining under mach3 control my mill just wanders off, this just happens on odd occasions. I have checked the wiring etc and I am at a bit of a loss.
Can anyone help please?

Hi Rich
I tried it with the sample file "ainsideprofile.dxf" so its not the DXF file.

Hi Art
I feel a bit of dunce but I cant get the files to open.
If I run the Lazy turn exe file and load the dxf files I get An open GL error.
And if I run it inside lazycam there is nothing on the screen.
To be fair I have never manged to run anything in lazy cam.
I have used d2nc succesfully and I have been using Autocad for 20+ years and can use Solidworks.

I cannot attend the uk cnc convention, would any kind souls be prepare to video the speakers (if they are agreable to the suggestion) so that we might watch it on the web?

Thanks
How good is the Leamington Spa show as its a long way from me?
I have just got my CNC machine working in anger about a week ago I would have liked to get a bit of a confidence booster.
