General Mach Discussion / Re: Enco probe stopped working
« on: November 21, 2010, 10:30:48 AM »
Ok, I think somthnig is up and its not electronic.  I have changed all the settings in the ports and pins to use either probe or input 4.  Neith work.  I examined the XML file that is stored in the C:\mach3 folder and I cant see any of the changes i have made.  Its like its not seeing the xml.

Am i looking in the right place?

I see what you mean, I will check tommorrow.  This does not seem right we spent around 3 hours changing ports over etc... Will update you tomorrow when I get an greater understanding.

General Mach Discussion / Enco probe stopped working
« on: November 14, 2010, 12:51:26 PM »


Hi,

I had a friend come over and wire up an Enco (Wild horse innovations) probe.  All worked and there was no problem.  I down loaded a blue screen set that already had probing built in.  I installed the screen on my workshop PC and put the probe in a chuck - Started the probe and when it got to the edge it did not trigger anything...I took the probe out and checked it over.  Visually everything seemed fine except now its not triggering anything.  Got a friend over with a multi meter and discovered that there was nothing coming out of hte port I had chosen to use.  So we move ports - this did not work either!

Is there some hidden switch or setting I have to tick to make the probe work under a different screen?

Any other ideas?  ???

....Help!   :-\

Thanks, I think you got it there hood, ill have to check but I think that I have the drivers set to 1/4 not 1/16th.  So ok the circle should be round ... why would it have one flat side?  Could the tool 'wander' ?

Ok s I have spent the better part of a year converting my mill to CNC, and sucess 3 weeks ago as it moved for the first time.

I had lots of problems during the conversion that were just unfortunate but hey ho I got there in the end, with pure bloody mindedness and the  help of the good folks over at CNCzone.

So now I have a problem, I have DTI'd the X and the Y axis and found that I have backlash on my new ballscrews (bugger!) the x is .2 and the y is .22

When I cut a circle I have a verry small flat on the circle, sadly even with backlash comp on (at least this time its only one side).

Hence the question about steps per...could this be the problem...I only ask as got my current figure by trail and error (160)

The ballscrews are supposed to be 5mm but as I bought them from china direct I think I have some problems with pitch they seem to measure 5.4, unless my digital calipers are broken.
Ok so 5mm pitch. 200 revs of the motor, direct drive no blets or gearing. 16 microsteps.  can anyone who is better at math than I confirm that htis should be 160.  Any other possiblites that could explain why i have one flat side one a circle.

Thanks for any help.
