General Mach Discussion / Re: Help ! "Radial Cut with Zdepth" toolpath from mastercam makes Skip steps ??

« on: January 04, 2011, 05:49:14 AM »

I did try lowering the Z axis acceleration, still the same problem
is this because of the Z ? something got to do with Z that cause this loose steps ?


I use Backlash Comp enable already.

now I'm thinking that my PC is not catching up reading the Mastercam gcode lines.

here is the picture of what I'm cutting.

it's radial with Z depth.

I use to use G64/constant stop before, it give me the same result, so I try this smooth const. Vel.

now I realize, this might help you to solve problem.
when the mach3 read gcode lines, it stop for split second before reading to the next line, it's not smooth reading, that's the moment "loosing step" ... I think.
now how the mach reads "stop" momentary ? does my computer too slow ? or need bigger buffer ? CPU ?

Z might be slower, it's because the ballscrew Z lead is like 1 inch, but X and Y is about 1/8 inch.

now how to set exact stop mode on x y and z ?

I'll try tonight.

I try to set the Step pulse and Dir pulse to 15us, I tought it solved, but it not.

I have this problem when cutting sphere using radial cut import from Mastercam toolpath.
no matter how slow the feedrate I choose, it always create loose steps.

is this a compatibility issue or my router setting is not right ?
I use very slow feedrate but still dosn;t solve the loosing steps problem.

anyone experience this ?

help...

Yes I read that before, but I can not set on the general logic config to get the same result like if I add G64.

what I want is getting the result like G64 but with changing the parameter on the General Logic Config setting.
I still get the stop motion whatever I change the setting.

I add G64 at the start it works great.
but how to change the Gen Logic Menu setting to make it works ?

I try to check un check the "Stop CV on angles, uncheck and check the G100 still dosn't work.
can you specify the parameter which one should be check or not ? and what degree should I put ?


now what it the different if I use CV mode or Stop mode ?
I only cut wood (router).

I really appreciate our help

When I cut circle or Z radial cut, I always get Pause for 1/50 second before reading the next line ?

I create the G-code from Mastercam X3, I already install the Post Processor.

I check the Mach3 setting, but nothing wrong... or I miss something ?
