wincnc settings for 3d

[A1CNC]

Can anyone help me understand why my 3d files run sooo slow?
Here is my ini file.

I have tried changing the accels, the g09 s # and whenever there is a move with the z and another axis the machine just crawls.

Thanks for any replies.
BTW, even when I am jogging with the keyboard, if I press the z and another axis the machine will crawl.

Thanks,
Eric

i am not sure as to why you have an accell of 350 under the g09 setting and my g09 is usually 15-30, lets see a 3d file and what program are you toolpathing in, things like to tight a stepover can make a file run forever, are you at 10-13% what type of machine do you have? also are the backlash (b) settings neccessary

always save your original .ini file before changing it!!!!!
to another location

Thanks for the reply Jim,
I actually have multiple copies of the ini on different computers, you never know when a hard- drive might decide to just go feet up. I had a lathe all dialed in using Mach3, I thought I was safe with a back-up of the xml file on that computer.Guess what, when the hard drive dies, so does the back-up!

I put the Accel under the g09 to see if that would help. I read something about it in the manual & thought maybe it would help, but it didn't.

My router is a practical cnc. It has steppers on it.

I use Bobcad for my toolpath. This file was from a bobart conversion. I used a .125" ballmill with .01" stepover. The machine only crawl when there is a z move with either an x or a y move at the same time. Then it seems like the 2 axis drop to ~ 10% of the commanded feedrate.

I could drop the backlash for 3d stuff but not for 2d precision parts.

Thanks,
Eric

a stepover of .01 is 5% of bit width and will account for major time in carving, i start at .025 or 10% and some times run 13% and sand a bit.

i have bob cad and have never used it as i am an aspire fan, that said you can still learn a bunch about carving on vectrics forum

http://www.vectric.com/forum/index.p...d5e80d63d489ba

there is also a gathering in november in pittsburg, it would do you well!!


the other issues are acell and feed relaionship and can be adjusted, kinda like a car racing to a curve, when to slow down and when to speed up in order to have smooth inertia around the curve

i will post my ini for you in a bit

here is my current ini, on my x3 machine i have another single head machine as well

hope it helps

Hi Jim,
I will try your "rule of thumb" for the stepover and see how that works.

Thanks for the link to the vectric forum, i will check it out when I have some time. Just popped inthe house to eat. Do you know which settings do which?
It seems clear as mud in the manual.

I use bobcad because most of what I do is industrial parts, bobart was just part of it.

I appreciate the help,
Eric

[cabnet636]

how you coming along any improvement?

Hi Jim,
Sorry to have fallen off the planet, I do appreciate your help BTW.

Last week was crazy, trying to keep up with the parts I was supposed to have already made.
I did some experimenting with the ini settings you sent and the router seems to be working better. I am running a 3d file from a cad program and that runs well at 100 to 150 "/min. I tried the feedrate override, if I increased that to be running at 200"/min I was loosing steps in the x axis. I haven't tried increasing the programmed feedrate to see if the same thing happens. I have in the past found that using the feedrate override vs changing the programmed feedrate would cause trouble.
I re-tried the file from the bobart and I think the code from that is my trouble.
Regards,
Eric
