Mach SDK plugin questions and answers. / Re: Threading problem

« on: June 25, 2012, 06:04:03 AM »

Hi Rich

Thanks for the reply. I tried setting both the debounce interval and index devounce to 10 and no change...

Our plugin reads axis position profile data from the Trajectories.Points buffer and sends them down our own queue to the closed loop servo controller. I'm having a chat with Art to try and understand how this should work with threading. I'm confused as to the differences between the parallel port type plugins and those like ours that just take the profile from the buffer.

Regards

Mach SDK plugin questions and answers. / Threading problem

« on: June 21, 2012, 11:37:47 AM »

Hi All

We're updating our motion control plugin from milling only to operate with a lathe and so I've set up Mach3 for threading using an index pulse pretty much as per the Mach3_Threading.pdf.

If I select "Spindle Feedback in Sync Mode" and program a G76 the diagnostics indicate "Wait For Trigger" and it just sits there. We never see "Threading" light up.

I can see the index pulsing on the diagnostic page and it seems to work with Spindle Feedback in Sync Mode" not selected (although I understand that this isn't the way to go).

The plug-in updates the digital IO in the "Update" function 10x per second.

Any ideas?

Thanks

Sean

Hi

We used to do this sort of thing with full-blown CNC controllers that had what was then known as "multi-process" capability. Synchronisation between the different processes was usually the main headache.

Just an idle thought but I wonder if you could configure and run multiple instances of Mach 3 to achieve the same thing?

Promote and discuss your product / Deva004 PCI servo and stepper controller cards under Mach 3

Hi all

Deva Electronic Controls Ltd. is an independent UK company with a long history designing and manufacturing a range of quality motion control and position measurement products. These products are used by a wide variety of international customers in many different applications. Please visit our web site www.deva.co.uk for more details of our company and product range.

Our principle motion control offering is the Deva004, PCI 4 axis motion control card which is available in either servo or stepper motor control versions, you can download data sheets, software and manuals from our website http://www.deva.co.uk/motion.htm. The cards are used in many industrial applications including CMM (co-ordinate measuring machines), robotics and metrology.

Whilst our customers typically develop their own application software, we have occasionally been asked for software that would allow the cards to be deployed in PC systems and used as a serious "G-code" based CNC controller. This has led us to develop a Mach3 plug-in for the Deva004.

We are looking to develop a relationship with any systems integrators who can see the benefits of and are interested in our products and would like to work with us as we gain experience in this exciting new development.

If you are interested in working with us on this, please contact me through this forum or via the support email address on our support web page http://www.deva.co.uk/company.htm#support.

Thanks for your time

Sean Kelly
