Hi Skatcat,

Check that you have actually released the EStop switch and it is working OK (there have been reports of an internal plastic clip which is factory fitted to prevent the EStop releasing - if this is the case then the clip has to be removed).

Sounds hard but my best recommendation is that you seriously consider replacing that T-D controller with a Gecko G540 http://www.geckodrive.com/geckodrive-step-motor-drives/g540.html
Also check out the Support pages on the Gecko site - their products are tip-top and the customer backup services are second to none.

Sounds like a bad install.

Try re-installing Mach3 (version R3.043.062 would be best) and see if that cures the problem.

From your earlier posts I assume you are still using the RnR USB motion controller. From another member’s tests it has been shown that the Direction signal from this board is not persistent but is resent following a break in the Step signal train. Your stepper glitch is indicating such a break in the data stream and that could explain it running backwards slightly then correcting itself.
This is not a Mach3 problem per say but your PC could be interrupting the data stream by carrying out other tasks as may be associated with power saving features (allowing USB devices to power down, screensaver, hard drive power down, etc., etc.). It could also be associated with electrical noise spikes etc. Fitting clip-on ferrites at each end of the USB cable between the PC and the RnR may help.
What bugs me is that this glitch is happening in more or less the same place and that I just can’t explain or understand but I will keep digging.

It's only a guess but check the case temperature of your Z axis stepper motor when this problem happens.
Just as a guide it should run at around 60 deg. C   If it is lower than this then you could try increasing your drive current by one setting.

Hi Robert,

I think you also need to contact Build your CNC and get a wiring diagram from them and any other information they have regarding the Blacktooth (they charge megga bucks for their stuff so they should provide excellent support).

In the meantime I will see if I can dig up any additional information.

Hi Michael,

Series relay sounds good but you may also need to use a shunt (unless the relay coil can handle the spindle motor current). Another approach may be to use a current transformer to drive the relay.

Excellent.  ;)

This is perhaps a lesson to us all - a backup copy of our Mach3 folder may, one day, save us hours of work.

Assuming you can still read data from your old HD copy your <profile> .xml from your old Mach3 folder (or xmlbackups folder) and paste it into your new Mach3 folder also copy and paste your license file, macros folder and any special screen sets you have been using.

If you cannot read data from your old HD then there are many HD recovery software programs available - some work better than others.

Interesting.

The obvious question I suppose is - does it still do this with the Shuttle (and any other USB devices) disconnected ?

Hi Robert,

Your .xml file runs OK here but you need to check (doublecheck) that you have specified the correct pin numbers for your X and Y axis Step and Direction signals.
For switching your laser (on / off) this article may be of assistance to you : http://hobbycncart.com/publ/cikkek/mach3_temaju_cikkek/switching_a_laser_under_mach_control/8-1-0-29

Which CNC controller are you using (breakout board / Drivers) ?
