Strange problem

[Clive S]

To me its strange that there seems to be no individual setting for X and Y inverts etc.

re
$3=5 (Step direction invert) ... Is 5 the correct number ? I would have thought 0 or 1 !!
$4=0 (Invert step enable pin)
$5=0 (Invert limit pins)

$20=0 (Soft limits enable) ... Is this enabled or disabled ?
$21=0 (Hard limits enable)

Sorry I don't know much about GRBL

You need to view the table that comes with GRBL to work out that question about $3=5 It is actually settings for reversing the XYZ motor directions without having to physically doing it with the wiring.


anything equal to =0 means disabled, =1 is enabled , other numbers are from the table above and are used in several of the settings.

Ah but the table did not show up in my crystal ball

I may have nailed the problem down?
Because I was getting the repeated bad results from the hardware I was using, I decided to change all the electronics again.
I used a new Arduino UNO, programmed it with the original GRBL 1.1h and then I tried again using the same CNC shield.
Same problem. So next I also changed the CNC shield for a new one, checked all my wiring very carefully and tried again.
Same problem.
I was starting to think maybe the is something wrong in the software, so I opened up Universal G-code Sender and tried that.
Straight away everything worked, I could home and travel in all directions without any problems.
So next I closed UGS and opened up LaserGRBL again, and tried again. Back to the same problem, so to me it is something that LaserGRBL is doing.

Problem confirmed. I loaded an old version of LaserGRBL and it works perfectly, so the new version has a jogging problem.

I bet you swore at that point :)
