Error: Homing Failed on any G28 situation
-
Hello!
I finally got to the electronics part of my coreXY/D-Bot-mod printer and Duet is making everything so easy. I have a 0.6 on my delta that works wonders.
Anyway, I used the reprap configurator to generate an initial config, then configured the 3 independent Z-motors (I have a Duex 2 too) and did all the tests on the CoreXY setup wiki page. Everything is movnig on the right direction. Endstops also report correctly on M119 and I am using a dc42 Mini IR probe that is also working fine.
The problem is any homing that I try to do ends with "Error: homing failed". What is weird, because it actually does all the homing procedure described on homey/homex: finds the endstop, goes back, and then again slowly. What I've noticed is that it apparently doesn't change the X/Y position (reported on DW or M114) to what is supposed to be.
I tried doing a G92 X0 when the X was at the correct spot, and then if I ask to home again sometimes it will show as being on -0.0 or -0.3.
I am out of ideas to try. I don't know if it's something mechanical as are my belts wrong, or something skipping (I am 80% sure that it's fine), or if there's something involving Duex that I am unaware of, but as far as documentation go I don't even see many of those errors on a google search.
I tried to enabled debug and see via USB what was happening, but I have no idea how to read the debug output so didn't help. I see in the code that this error is described here https://github.com/dc42/RepRapFirmware/blob/c1983ffa6d33e88f491f1c21f35310fe2f3c88c8/src/GCodes/GCodes.cpp#L424 and if my C isn't failing me means that it's not recognizing that homing actually happen?
Anyway, any help here would be appreciated
This is my hardware info
Firmware Name: RepRapFirmware for Duet WiFi Firmware Electronics: Duet WiFi 1.0 + DueX2 Firmware Version: 1.20beta2 (2017-10-25) WiFi Server Version: 1.20beta2 Web Interface Version: 1.19.3I tried to rollback to 1.19 and it had the same error. Didn't try any earlier version.
I will attach the relevant files and a debug log at the end.

There is a bug with CoreXY homing in 1.20beta2. Please use 1.20beta1 or 1.19.2, at least until 1.20beta3 is available.

Oh welp, that solved it.
Weird that I was pretty sure I had problems with 1.19 too. I guess I didn't actually try it.
Thanks DC

SO, guessing it still isn't fixed in the full release as I'm using 1.2 and it's doing it on my CoreXY .
. question, is it an issue really other than "reporting"? it seems to home and register actual location and all. though I guess it wouldn't go a print huh? (still building the printer and just playing with the movement, no head carriage on it yet) -

Same thing he stated above, all axis home, seem fine but spit out an error 28 homing fail.

If you've got no head carriage fitted yet, I'm curious as to how you are homing all the axes. What does the switch status indicate in the machine control section of DWC?

Simple wheel plate, actually triggger the switch manually myself for y. Not a clue what the DWC is?

DWC = Duet Web Control. I kind of assumed you were using that to home the printer and that's when you were seeing the error message. I'm very confused now because you said "all axis home, seem fine but spit out an error 28 homing fail". Yet you are triggering Y manually. How about Z?
The "bug" appeared briefly in 1.20 beta2. It wasn't there in 1.20 beta1 and was fixed in 1.20 beta 3 and later version including the final release. Suggest you get a bit further with the printer then get it homing all axes properly and report back if you still have an issue.

OK, yes using the Duet Web/Browser control page.
Z and X end stops are mounted. Y is just the wire an end stop sitting on top the printer and I click it with my finger. simple testing of movement as I am designing as I build. when Z triggers the home it works fine, both X and Y spit out the error 28. Again, X is mounted so can't blame it on my setup. Also notice that when I go to home X(or Y) if I home Z first, the control panel is saying Z is homed, till the error 28 and it goes back to all 3 not being homed.

video- just for viewing to see what's going on and what I am likely missing?
