Spurious (?) "Error: G0/G1: insufficient axes homed" message?

fcwilt

Well we need to see the other homing files.

And if you will get into the habit of posting such files with the </> tag it will be easier on us all and much appreciated.

You existing homez.g file assumes X and Y are homed - that may not always be the case.

That is most curiuos.

I would add something to check the homing of the X & Y axis at the top of homez.g file. I do them individually-not sure how your machine is set up.

if !move.axes[0].homed || !move.axes[1].homed     ; If the printer hasn't been homed, home it
   M98 P"0:/sys/homey.g"
   M98 P"0:/sys/homex.g"

I would put a M564 instruction at the very end of the homez.g file to make sure that it gets applied in case its forgotten elswhere.

M564 S1 H0                                      ; limit motion envelope to that defined by M208 in config.g

in deployprobe.g, the M564 is in the middle section between the 2 other if statements.
I am not certain, but I believe that RRF will parse the entire macro on execution-
it might be better to put the M564 statements at the very beginning and the very end in case the loops abort partway through.
The location of the carraige may be relavant

if its outside the envelope because we gave it permission to go there
while it was still outside the boundary, we took that permission away,
moving from that forbidden zone to the safe zone might be trigggering that error message.
That message might be generic appplying to all motions outside the M208 definitions.

That should be easy enough to test barring and official clarifications.

I have experienced funniness with spaces and tabs in files for whitespace. Sometimes I have gotten errors for inexplicable reasons, and after parsing the files for tab characters and replacing them with spaces, things behave different.
I see tabs in your homez.g file at lines 15, 18, 32, 34,

@sinned6915 Greetings -

I added your if statement to my homez.g file but it seems that current RRF 3.3 already checks for an attempt to home Z before homing X and Y, and responds with this message in the console: Error: Must home axes [XY] before homing [Z]

I added a final M64 S1 H1 to homez.g without change to the spurious message. I've since removed that line to continue troubleshooting.

I've moved the M564 to be before all G1 movements in both deployprobe.g and retractprobe.g as suggested, with the M564 H1 S1 after the G1 movements in each file.

Not sure about item 4.

I've checked my latest files for tabs. I use VSCode which switches tabs to spaces be default, but perhaps if I edited via DWC for changes, some were introduced there. No change in bahavior.

I did notice one interesting thing. After I complete homing X, Y, and Z, and get the error message, if I home Z a second time, I don't receive the "Error: G0/G1: insufficient axes homed" message" after the second execution of Home Z.

@fcwilt I'm uploading files using the icon for "Upload files." If there is a better or different way to do that, please point me at those instructions. I've added the remaining homing files, as well as the updated files after the changes discussed above.

Thanks,

John

I've posted your files using the </> tag. It gives each file it's own scrolling window which means we all can see them without downloading.

You just enter the tag and the paste the contents of a file between the start ** and end ** characters where you see the text undefined.

How much work would it be to add a Z endstop sensor?

With that you could home Z at any time without having to insure that X and Y are homed first.

I have Z probes on all my printers but I also have Z endstop sensors on them.

@johnocfii

Could you explain a bit what the deploy and retract files are doing?

How does it all work?

Thanks.

@fcwilt Thanks for the example of posting that way. I use that for small segments of code, but hadn't realized it was a good way to post complete files.

As far as a Z-endstop -- I suppose it is possible. I haven't seen the need. As I mentioned above, the printer is working fine, just seem to be getting a message that does not correspond to the printer's behavior.

As far as the probe, you can read all the details on the Github page: https://github.com/nionio6915/Euclid_Probe/blob/main/README.md#probe-calibration

But in summary, a simple switch is magnetically attached to the carriage. The deploy and retract files handle the logic to determine if the probe is attached or not. The deploy macro will travel to the dock and "pick up" the probe. The retract macro will return the probe to the dock.

Well as you see if you click the Home Z button on the DWC you will get an error because homez.g attempts to move on X and Y to bed center.

You cannot, of course, move on X and Y to a given location until they have been homed.

I much prefer to be able to home Z first so I can be sure the bed is clear of anything on the X or Y gantries.

But to each their own.

@fcwilt he is using a magnetic coupled probe

you dont need an endstop, the probe works as both endstop and probe. the corollary is BLTouch- same device, 2 functions.

i suggested that the conditional get added to check the home status

I know that.

I am suggesting that having both is a better approach.

Homing Z with an endstop is faster and you don't need to have X and Y homed first.

I only use the Z probe for things that require a Z probe - such as setting the Z=0 datum.

It's just a personal preference based on having built 8 printers.
