Solved Question about M564
-
My duet is driving a 1000x1000 workbee cnc and I'm having some issues with homing. I had an M564 command in my config file which allowed me to drive the machine without having to home it to allow me to home the machine earlier but since taken the command out. Before taking M564 S0 H0 out of config, I was able to home everything individually and home all successfully. No, my machine will home Z, but not X, Y, or All. Additionally, it will not home all even if I have everything commented out except for the Z moves (which was proven to work with homing Z alone).
The machine's max area is X770 Y800 Y94. The errors I'm getting is a "G28 G0/G1 target position outside machine limits". I'm wondering if I were to put an M564 S0 H0 command at the beginning of homeall.g and M564 S1 H1 command at the end of homeall.g, will it turn off soft limits during homing sequence then turn soft limits back on when its finished? Does anyone have any other possible solutions to my issue?

probably better to post your home file(s) and get the appropriate G0 moves with H1 set. (i suppose we'd need the M574 and M208 config(s) as well to verify)
-
Yes, please post your files. config.g and home-.g
It should never be necessary to turn off limits, or turn on "move without homing", to home. Getting axis limit definitions right, and the content of the various homex.g files, homing will work on (almost) any setup, without changing those.

@Danal I'm at work so give me a few hours to provide them. Do you want me to give the files or is copy/paste enough?
-
Either way. If you do copy paste, please put three backticks on a line by themselves at the start/end of the paste.

@Danal I'm gonna test this since I never done that before
test line 1 test line 2
That is cool! Okay, I'll be back in a few hours with the routines. I'll tag you. Thanks.

G1 Z-3 F2400 ; go back a few mm
as the second line needs H1 or H2 depending on what you want to achieve. In general you want to home z first and avoid it in the first place i think

Several things to clean up before we solve the real problem:
@Perseveranze said in Question about M564:
G1 H1 X1500 Y1500 F2400 ; move quickly to X and Y axis endstops and stop there (first pass)
These should be separated (even if this statement works).
AND, every move in home.g should have H1 or H2 in it, even if we don't expect it to hit the switch. (the -3 move)
G1 H1 X1500 F2400
G1 H1 X-3 F2400
G1 H1 X1500G1 H1 Y1500 F2400
G1 H1 Y-3 F2400
G1 H1 Y1500@Perseveranze said in Question about M564:
G92 X800 Y770 Z94 ; Set Home Position please change to your machine size.
All the G92 should go away completely. If that results in the coordinate being off after homing, we will fix that a different way.
@Perseveranze said in Question about M564:
M564 S1 H1 ; Disable jog commands when not homed
This also should not be present, or more specifically, if there are any H0 commands anywhere else, they should go away.
Try that, and see if it homes at all. Again, if it homes but coordinates are wrong, we will fix that a different way.
-
Oh, and it looks like your limit switches on X and Y are at max, correct?
-
@Danal I'll start working at editing my files right away, and yes, I home at max
-
@Danal Everything works as intended now!
Thank you so much guys!
