General Mach Discussion / Re: Probs with RoutOut CNC Mill 2000

« on: June 21, 2015, 08:01:30 AM »

Mike,
My experience of Routout CNC was that their service was excellent, I needed a part for an older model control box and they were able to find me a direct replacement which was very reasonably priced, I'd done the fault finding and identified the part required though.
I'm not surprised that they may not want to get involved in remotely fault-finding a second hand machine/PC/software, imagine how much time can be spent in a year helping people with second hand kit who will never spend any money with your business.
This is definitely the place for free support of second hand equipment ;-)
Regards,
Nick

General Mach Discussion / Re: Hello, can I have suggestions for implemantation ..

Only the manufacturer controler is compatible or any PLC based one can be used.

If the manufacturer publishes enough information you may be able use an alternate PLC.

The second question.  In your opinion, should I continue projecting my machine based on this servos or should I chose then Nema 24 or 32 instead? 
These servos seems to work with a lot more precision but I think I may have to invest much more money to complete the installation..

That will all depend on what information you can get from the manufacturer and whether you think it's viable for you based on that, considerations include whether you have the technical capability and more spare time or money but it's definitely a decision for you.
If the drives do have accessible step and direction signals internally it may be possible to determine where they are and inject local control signals directly at that point, you might need a meter & scope to find them though,
Regards,
Nick

It looks like you may need a central PLC based controller for the drives, the manufacturer's literature states that they are designed for food and packaging production environments.

IEC 61131-3 refers to PLC programming standards which implies that either the drives incorporate a PLC or that one is required to drive them, if you can get technical documentation from the manufacturer it will probably make this clearer

From Page 29 of the the Danfoss product overview

"The ISD Master System is necessary to control the integrated servo motors.
The system is DC-driven network connected througg a common master computer control"

Keep us updated on your progress with these,

Mach3 under Vista / A Big Thank You

« on: June 02, 2015, 07:16:42 PM »

To all the usual suspects and other contributors who answer support questions here.

Today my old Windows XP PC finally bought the farm, with the help of the search tool and the wealth of information available here I was able to get a clean-build Windows 7 PC up and running with Mach 3 fully configured in an evening.

Thanks Guys!

General Mach Discussion / Re: Rotary carving skewed

« on: April 26, 2015, 10:38:55 AM »

as a side note I noticed the last time I did a profile cut of text that at a production speed
most of the letters had a slight skew at the bottoms like a lower case l where the bottom should be 2 equal length vertical parallel lines connected with a horizontal line what i got was 2 vertical parallel lines but one slightly longer than the other and the horizontal line was angled they all touched but not right hope that makes sense I cant remember if it was top and bottom or just the bottoms it was a few weeks ago.

I can cause this issue when diamond-drag engraving both 2D and wrapped by running faster than the machine/pc can handle, slowing it down restores normality,

Nick

Have you manually checked your A-axis motor step settings by marking zero then running it through several thousand degrees and checking zero is still aligned?

*****VIDEOS***** / Re: ECC 4th Axis Test

« on: April 15, 2015, 04:24:53 AM »

Facing 2 sides and roughing the curve were carried out as indexed paths, at -90, +90 and 0
On the path cutting in the video there is A-Axis movement but the video from my phone didn't show it very well, it's only a little but then all that's necessary on a longitudinal path like that is to keep the ball end cutter optimally presented to the work.
In short, yes it is ;-)

You can try disabling all the laptop power management features in firmware and operating system, it may help but it might not,
