Thanks for all your help guy's

However, this is not quite what I'm looking for.
All these seems to need to copy the code after the G52 (etc) ??

Is there a way to "loop" at the new G52 location?

Perhaps this was a special feature of the machine I used to use?


Thanks

Thanks Rich,

Looks like I'm going to have to look more into work offsets.

I used to program a CNC drilling machine for printed circuit boards, but that was in 1988 / 89, so forgotten allot.
However, I dont remember having to use increasing G44, G55 etc.

Time to hit google

Thanks for pointing me in the right direction :)

Hi All,

Tried to search for this solution, but nothing seemed to quite do what I wanted.

I have a 3 axis router table.

I regularly nest my parts into half a sheet and cut.
But sometimes Ill cut 2 sets on the one sheet, by moving to X1200, Zero X, and Run again.

Is there a way to program a "step" so my machine 0,0,0 is unchanged?

Another simple example would be to cut a small square part, then others next to it to make a pattern of, say, 10 X 10 squares on a sheet

Thanks in advance

Regards

Hi All

UPDATE

After stripping down all the electronics on my machine, I finally found the problem

The Gecko's I have has the cable connect terminals
I found out that these are actually "push-on" on pins on the Printed Circuit Board.
(they looked liked they were soldered to the PCB)

Its this push-on connection that burnt-out, causing intermitant connection
My slave was the worst, but all the Geckos connectors are showing signs of burning out.

Marcus of Gecko Drive has been very helpful, and have found a local replacement connector.

However, if it happens again, I will go to a soldered connection to an industrial connector for the motor cables

Now, I just have to finish putting the electronics back together.......

Thanks guys,

Will look at the whole wiring set-up in case something has broken / loosened
I am using good industrial shieled cable on everything, but know crimped connectors can some loose with time
Want to move my control box anyway, so now seems a good time

Will let you know how I go :)

(might take a weekend or 2)

Hi All,

Part 2 - the continuing Saga

Problem.
When Jogging using the keys, just tapping back & forward on any axis, the motors 50% of the time, go the wrong way.
Which is particularly nasty when you have a slave on the X Axis

Brief History
I have a 3 Axis Router, with Slave on X (B Axis)
Running a ESS with breakout board
Licenced version of Mach 3
Been running mostly fine for about 2 years...... and then......
On the weekend I was doing a bit of 2D cutting, and by the end of the day, my X-Slave kept stopping to the extent that the machine is unusable

What Ive done so far
- New install of Mach 3 + ESS Driver
- Running just a basic machine ATM, no limit switches or spindle control
- Tried another computer (PC)
- Original computer will not acknowladge ESS any more (with new or older driver - Laptop)
- Tested with Parrallel Port BOB (on PC)
- Swapped Gecko's (Running 4x G203V)
- Tried new motors
- Slowed down Speed & Acceleration
- Sped up the Speed & Acceleration

When the motor start rotating, it growles like its doing allot of small steps while accelerating until it reaches speed

Am totally confused

HELP !!!


Thanks

Thanks Hood,

Ive been swapping motors, controller & ports & pin but the problem remains on anything set-up as slave.

Looking much more like a software issues, with everything pointing towards the ESS.

There is also a new drive out for the ESS (addressing Slave issues), and will look at doing a reinstall of Mach3 from scratch.

See how I go, and will post the results here in case someone else has a similar issue in future

Attached should be my XML file.

Some of the ports may have changed, as Ive been trying new ports and swapping controllers
