I have a little project where I need to engrave serial numbers on about 200 pieces. I found this old post in another area of the forum and this macro sort of does the trick.  I started to modify it to get it to work the way I wanted but ran into trouble with some of the deprecated commands. It would be pretty helpful if I could get it to work as I can call the macro as part of a larger program to get the serial number on the part.

The macro is attempting to set each of these variables to the current X and Y axis DRO readouts. This doesn't work and I think the 'getdro' command is obsolete. Plus I think the syntax is wrong anyway.
Setvar(1301, getdro(0))
Setvar(1302, getdro(1))

Here is the original topic:
https://www.machsupport.com/forum/index.php/topic,11018.0.html

What I really need help with is what is the proper syntax to define a new variable, then set the variable to the current X axis DRO (and similar for the Y axis)? I played with the getOEMdro() command but I don't understand the syntax and how you would turn that dro reading into something that can be used as an integer. I'm not much of a programmer so the syntax and logic is a bit tough for me to figure out. I'd greatly appreciate any advice or alternative options!

 
Code: [Select]
It wil start off by engraving       S/N:     then adds the serial number    IE:    S/N: 090300001  ,  next run  S/N: 090300002 , ETC

General Mach Discussion / sudden onset of Stepper stalling
« on: March 08, 2017, 08:39:56 PM »
I've got a Hoss mini mill clone that has been working great and almost daily for 18 months. Now it is suddenly stalling the Z-axis on a regular basis either while executing a program or just jogging. No pattern for when it happens. I verified that it is not a physical resistance issue on the machine. Never had problems in the past with stalling either, but it's not going away on it's own.

Is it possible I have either a dying breakout board or driver??? Or, is it possibly a windows stability issue? I've attached my XML file as I know you guys love looking at them!

I use the following:
KL-4030 driver
CNC4PC C-35 breakout board (parallel port)
Window 7 computer (only runs mach3, does not even connect to internet)
NEMA23 382oz/in 3.0A Stepper Motor

I had already considered moving to a motion controller as I'd read they offered more stability. Either the
UC400ETH Ethernet CNC Motion Controller
or the
UC100 USB to Parallel CNC Motion Controller

Any ideas on what I should do here?
thanks in advance.

I've been using Mach3 Turn for many months on a converted bench lathe and everything has worked as I expected so far. Most of my problems have been easily solved by reading the forum posts.

I recently added a C6 speed control board from cnc4pc so I could use spindle control (I use the C10 breakout board, and C3 index pulse card). I thought I configured it pretty well and get close to the requested spindle speed, both in the Mach3 DRO and against a laser tach.

BUT, I'm experiencing some really odd behavior with regards to G95 and can't figure out what's going on. On an intermittent basis Mach3 will reduce the feedrate, while executing a program, to some unusually low number like 0.0002"/rev. It will often be on like the first couple of roughing passes, but then Mach begins to execute the feedrate specified in the program on later passes. It usually fixes itself as the program goes on. Sometimes it doesn't, and I have to restart the Mach software.

If I stop the program and enter a feedrate in the MDI, it executes fine. It only occurs while executing a program. At no time do I see a drop in RPM in the Mach 'True spindle speed' DRO

What could possibly be causing Mach to ignore a feedrate as specified in a program, but do so on an intermittent basis, and then execute the feedrate later in the same program?

In general I use the following syntax for example:
G97 S800 M3
G95 F0.004
G01 Z X whatever...

Under 'ports & pins' -> 'spindle setup' both 'spindle speed averaging' and 'use spindle feedback in sync mode' are checked.

What am I missing here?

Thanks for any help!
