Yes and it is 123 pages. Here is the link.

General Mach Discussion / Re: How to make Lathe G83 peck run faster

« on: April 05, 2013, 07:51:34 AM »

Paul,
Have not done any peck drilling in a long time on the lathe. When i did i didn't use the G83 but rather used the lathe peck
drilling macro (M830?) which can be found in the link below. I think it will address what you have found.

BTW, NFS has a wizard for the lathe that you may want to explore.

General Mach Discussion / Re: Losing Pulses at lower accelerations

« on: April 05, 2013, 07:13:52 AM »

10k,
What do you want to do?
Find a reliable operating configuration for the machine as is ,or, have a machine capable of running at high velocities / accelerations?

You have what you have, you modify what you have to improve the performance, or you design the machine to preform at some level.

There is a big difference between the above and there are basic limitations and compromises that need to be made.
One could write a book on it.

pcbcnc3020,
There is a manual for LC in Members Doc's. See page 41 for drilling holes.

General Mach Discussion / Re: G76 threading issues - any thougts?

« on: April 04, 2013, 03:29:30 PM »

Hi Art,

The code generated from the Simple Threading Wizard ( M1076 configured for G32 output ) always had double G32's as shown in the format below.
Use it whenever I do threading, never questioned the double G32's, but then, never had a problem when using it.

(Decrement = 0.005 pass 1)
G01 Z0
G32 X0.245 Z-0.0014 F0.025
G32 X0.245 Z-0.9969 F0.025
G01 X6.25 Z-1 F0.025
G00 X6.25 Z0
G00 X0.25

Simon0362,
Have you contacted Calypso about this problem?
- I don't use MSM and don't know what version of Mach they want installed with MSM
- I am not sure that you want to change between screens when using MSM as that could / may create problems
- Do you have both MSM and Mach installed together on the same drive? Ask Calypso if that could create problems.

So my first concern in addressing your problem is that your using MSM and that in itself could be a culprit.

Later,

RICH

G-Code, CAD, and CAM discussions / Re: G-Code issue - different part than the design?

« on: April 04, 2013, 07:33:04 AM »

Loosing steps can be caused by a number of things. You must allow some headroom in your velocity and  acceleration settings in motor tuning.
The headroom i am talking about is reducing the configured motor settings so that there is  adequate torque available for cutting, rapid moves,
and addressing quirks of the machine ( like a change in the torque required to move the axis at some point along the axis).
If the skippping is repeatable it's usualy easy to adjust settings and do away with the problem. If it is not repeatable, and a good example is skipping during
3 axis machining, chances are that the motor is inadequate and that can be caused by a number things.

Common mistake is when speed is considered more important than reliability / repeatablility. Additionaly, lack of experience on cutting different materials etc, with the same machine.

The system needs to be designed from the beginning to meet the requirements of what you want to do.  When the user understands the big picture
and works within a reliable operating zone, skippping will not be an issue.

You may want to use a piece of scrap to gain some experience on using your machine making note of what it can and cannot do when machining different materials. If an axis skips you will loose position, it can be minor or major as to the degree of position loss.
