Terry,
Thanks so much for this development.  Absolutely fantastic and brilliant.  Now I have get get my little custom rotary engraver back up running.

My Best,

Alan,
After your fresh XP install, did you run Windows Update?  Takes some time to get all of the updates (usually necessary to run Win. Update several times to fully update).

Tweakie,

I mounted my camera today and will install buttons and macros tomorrow.

Perhaps I'm just lucky, or it simply speaks to Chinese quality non-control, but my camera is solidly fixed in its housing and does not move as you described yours.

Thanks for once again developing a project that makes cnc easier.

My Best Regards,

OK,
Further exam shows I was not looking at the code properly.  My apologies.

This may not be a backlash problem, but may be a screw pitch variation issue or sticky axis bearings .  I see similar banding with my laser diode machine when burning images if the oilite bearings and shafts are dirty.

Ansen,

In your gcode file, the first gap in the bottom row of dots (right side of block 1 to left side of block 2) is 0.1278765 inches wide.  This is not caused by backlash.  Shows up in my tool path very plainly.

My mechanicals are linear bearings and Thomson shafts - very free moving.

I've recently changed to a different laser diode driver and don't use M10/M11 commands now, but too early to say my issues are gone.  If it happens again, I will revert to an older version (.022) to see if the issue continues.  Since others in this thread don't use the M10/M11 commands they don't seem likely to be the problem.  The only commonality we have seems to be the latest lockdown version (.066).  The last I remember, Ver. 066 was development and .022(?) was the lockdown.  I missed the change.

The reason I asked is that ever since I started using the later development versions to be able to use M10/M11 codes with my laser diode machine, I have experienced similar issues infrequently.  For no apparent reason, Mach will suddenly lose steps on a normal gcode line (ex. - G1 X0 Y0) that has worked flawlessly earlier in the same file.  Shutting down and restarting Mach sometimes helps, sometimes not. It is certainly not my controller or settings as I tried all the steps already recommended to you, and they do not help.  The problem seems random and unpredictable.  My opinion is that Mach is suddenly issuing step signals that ignore the feed rate as well as max. velocity settings.  I know it is not my code, as it only uses G1 commands for moves, but I don't know if it might be related to the use of the M10/M11 commands.

I am using a Dell Optiplex GX270 with pport- perhaps that's the commonality?

Hopefully someone else has seen similar behavior and will post about it.

What version of Mach are you using?  If not the lockdown version, try that.

I purchased from a seller on eBay.  Since I have not received it yet, I am hesitant to post a link to a specific seller as a recommendation.  Just do a search on "endoscope" and lots of choices will be displayed.
