Z-drives not moving, new Duet3

Heide

I forgot about the K1 Z3. It is from the configuring of RRF for coreXY printer. I can not remember what the original code was from Config tool. But I will try with the tool again

Heide

This is when homing Z.

But I would think that it's normal, when not homed

Heide

I have tried to move the gantry up and down (I'm not happy doing that, but I wanted to be sure that there are normal movement), and it feels as it should

Heide

If I use this command it gantry moved up, without any problem.

@heide I've edited your first post to put your config and homing files in code tags, which makes it easier to read and find the relevant bits.

I think this is an endstop issue. Your Z homing is using two methods:

When you call 'homez.g', it uses an endstop switch, and it is configured to trigger at the MINIMUM Z, ie when the nozzle touches the bed, with M574 Z1 S1 P"io3.in". Is this correct? The homing move is G1 H1 Z-200 F100, so it's moving the bed up. Also, a quirk of homing is that it relies on the M208 settings; currently you have the Z maximum set to M208 Z300, so it's possible for the Z axis to move and not hit the endstop. This may also cause homing to fail.

When you call 'homeall.g', it's using the Z probe. homeall.g should work correctly, assuming the probe is configured correctly.

The comments in the config.g are slightly confusing. It talks about moving Z up and down. But this is based on a machine that moves the nozzle in Z, eg Prusa i3. For a CoreXY, think of it 'Z up' as 'increasing the distance between bed and nozzle' and vice versa for 'Z down'.

Edit: Sorry, I see in your later edit to homez.g and homeall.g that you are using just endstops, not probe.

droftarts

@heide Can you describe where your Z endstop is? Is it the same as the Z probe? If so, you just want to use G30 for homing Z, not command a move.

@droftarts the endstop is not assigned as the probe. It's placed near the bed.
I have tested it, and it works.

M574 Z1 S1 P"io3.in" correct
Just to be clear the bed is not moving, the gantry is.
I will a just the Z to 400

Ah, yes, forgot it was a Voron!

the endstop is not assigned as the probe. It's placed near the bed.

I realise that now, looking at the assigned pins for Z endstop and probe. However, if you have a probe, and you can home with that, what is the function of the endstop? It would be better to have it at the top of the machine, furthest from the bed. That way, in the event of a loss of power, you can home Z to the top, and continue printing. Home at the bottom, and you're more likely to hit the print.

I will a just the Z to 400

Yes, just needs to be bigger than the value set by M208.

Heide

@droftarts I learn all the time, but that make sens somehow. But I my case it does not matter witch one I use. I does not move at all. It moves when I punch in this code

droftarts

@heide Hmm. I think that as that works, it's got to be a configuration issue. Can you post your current config.g, homez.g and homeall.g, preferably in code tags </> on the editing bar. Also post response to M122 and M98 P"config.g"

Ian

Heide

@droftarts Here is it. I hope that I have done it correctly with the </>, have never used it, but I will gladly learn it.

After homing movement of X and Y together, X and Y shall be moved into the same direction (negative X and Y) again some distance. This shall ensure that both X and Y are homed. Then a litte backwards (which is positive value here) and slowly with - again to the endstops.

@joergs5 I will change this tomorrow. But I'm sure that I have already tried it. (I have tried so many things today)

The risk is high that you mixed something up by trying different things.

First thing to check is that G1 H1 X-100 and Y-100 move your hotend into the correct direction toward the endstops. Then please try my proposal.

What I do if I am not sure about correct codes, I run them line by line directly in the DWC command line and check that in this case the first, second, third endstops are triggered as expected. There are a few G-Code commands which can be run only in a specific order (drive additions and their mappings), but most commands can be tested this way.

@joergs5 I will, and I am aware that it is posible to mix up code. But every time I change it to something else, I whipe the code and saves it i Word. Then I can retur to it later. Then I try a New code. But the ideer about taking a step at a time is brilliant. Did'nt think in that direction

Error: Bad command: Put G/M Codes in here to run when Tool 0 is about to be activated

Just to explain this error; you have T0 in your config.g, so the tool change macros get run. As no tool is selected, only tpre.g and tpost.g are being run. It looks like the text at the beginning of one of these files is not commented out correctly, with a semicolon ; as the first character.

I've had a good look at your files, but I can't see what's stopping the homing working. I think try @JoergS5 suggestion of stepping through the GCode of homeall.g and homez.g, and see what works correctly and what doesn't.

@droftarts thanks for the time you have used. And I am really sad that there are no errors, because I then maybe have a problem. I just can get it. It can run with no errors, with the code I postes earlyer today, when I tested. I will do as @JoergS5 proposed.

G1 H1 X-240 Y-240 F3000

I have two additional ideas for your tests. The -240 will probably not be sufficient, because your M208 says the axes are 300 long, so I would take higher values. The goal of this line is that one of the endstops is triggered.

The second idea is, when I run G1 commands in the DWC command line, I prefix G90 or G91, so I am sure the command runs in the correct mode. E.g.:
G91 G1 X100
This is important in the homeall, because there are several changes of G90 G91 inside. (NB: I don't mean that homeall is wrong: the G91 G90 sets mode for the following lines. I mean, to be sure you're in the right mode when executing it line by line)

Okey, what I know for now, is that it seems that the endstops X and Y prohibit the gantry to move after they are activated, it is like they hold on to it (locks it). I tried to force (not my intension, but needed to see if I could move the gantry when I did) the gantry away form the endstops (X and Y), and then I can move it. I will need to test some more, but that must be later. (Need to be somewhere else) But I will be back I'm so happy for this community, and your help, I hope I can contribute some day
