Mach Screens / Re: labels incorrect in mach3

« on: February 25, 2013, 09:42:04 AM »

I would have to look at it in a screen designer to be doing anything but guessing.

That's very interesting Hood.  Yes, it certainly looks like there is a sudden move, but its AFTER the backlash comp move in my case (it registers on the mach3 screen DRO), so that may not be behaving as intended in this case.

It would be nice if there were a checkbox for this setting!  Maybe there is but its named something I am just too slow to pick up on...

Thats the backlash Comp. enabled checkbox.

   Good, it will be interesting to see how and when it changes the moves BLC generates.  Please do keep us posted as this has been the most intensive testing posted so far that I'm aware of.  You have a great test bed.

This has been for me as well odex.  Have you tried your test while adjusting the shuttle speed in general config?

I would just go back to the older version that worked correctly but I cannot find anywhere in it where I can change the homing order.

I would say yes, rapid moves need to compensated I'm just not sure how or when they come into effect.

Thanks for testing.  It has been interesting to say the least.

Get some rest,

I'm sorry, in the code you posted, the last line is a G0, needs to be G1.  I dont think BLC has any bearing on G0s

@Chaoticone
ok, thats what I assumed. I did that with the following code:

G1 X0.3382 Y1.8169 F20
G0 Z0.125
G1 X.3362 Y1.8129    <-- TAKE UP .002 AND .004 BACKLASH in the opposite direction ON X AND Y RESPECTIVELY
G0 X0.3359 Y0.522
repeat...

Running under the same snails pace settings this *seems* to alleviate the lurch condition in the Y axis. Tried under both ES and CV.

Even as it finished going to x0 y0 there were no lurches?

OK, say you got from xo yo

G0 X0 Y0
G1 F30 X-2 Y-2
X-1.996 Y-1.996  *If backlash is set to .004
X0 Y0
