General Mach Discussion / Re: No stepper response after Mach3 software update

« on: January 09, 2015, 03:30:21 AM »

Perhaps the first thing to check, assuming you are using the parallel port for communication, is within Mach3 Config / Ports & Pins that the Port#1 is enabled and set to the correct address for your parallel port (check it's address in Windows Device Manager).

Next check that the correct port and pins are allocated in Config / Ports & Pins / Motor Outputs. Also that any Enable signals (if required) are set in Output Signals.

Your previous .xml file (usually called Mach3Mill.xml) should have all the correct settings so transferring this file to your new set-up is usually all that is necessary to get things up and running again.

Not yet Dani, we need to wait a while longer.

Tests have now been carried out with various wires and these have 0.006”, 0.013” and 0.020” diameter phosphor bronze wraps.

Still learning as I go.

If you go back and look at Brian & Benny's Coil Winder screen then examine how it creates the necessary Gcode it will answer all your questions.

Basically, the spindle (A axis) is set as linear but both Absolute and/or Incremental moves can be used in the traverse (X axis) as appropriate. The feed-rate, whilst winding, will always be a blended rate (between A & X) but, usually, the rotary axis (A) will be the limiting factor as far as maximum winding speed is concerned.

Hope this helps.

Perhaps, as a starting point, check out Brian & Benny’s Coil Winder Screen. http://www.machsupport.com/software/downloads-updates/screensets/
I think this should provide you with a good basis for your intended project.

(I have recently used a modified version of this screen for, single layer, Guitar string winding http://www.machsupport.com/forum/index.php/topic,28721.0.html still a long way to go but getting there slowly).

Hi Terry,

The test rig just has a felt pad friction type of tensioner for the wrap wire - it works but it is crude and only suitable for testing.
I am not yet sure of the benefits but measuring the wrap wire tension as close as possible to the actual wrap seems to be favored so I am currently working on an electronic device which uses a rotating version of the conventional 'dancer' to measure the actual tension in a feed-back loop to a disc brake on the wrap wire spool. This will be fully adjustable, for the different wrap wire diameters, and provide 100% repeatable results - assuming it works.

The full size machine has just gone through it's third rebuild but I think it is going to be a long way off before it will be winding a full set of strings.

A short video winding nickle wrap wire onto a music wire core.

At the moment tests are limited to 2,000 rpm as I have encountered technical issues when running these 200 step per revolution motors at speeds over 2,500 rpm.
I am currently awaiting delivery of some different (24 step per revolution) motors which should be good up to 15,000 rpm whilst, hopefully, still having sufficient torque for the job.

Hi Wadero,

If it would be of any help to you - zip and post a copy of the Gcode which has the problem I will run it and see if the problem occurs here.

DRO  is consistent with position and not with the instruction.

One possible explanation is that you are mixing G90 / G91 commands in an incorrect manner.

Thanks again Terry – I will try that.
