G30 Insufficient Axes Homed For Bed Probing
-
@deckingman I'm editing the file from the web interface.. I go to Gcode files, right click and edit.. I have also created a fresh Gcode file, and uploaded it through the web interface.. same result with either method.

@steve-lynch It sounds like something is amiss with your sd card or the way you are editing the homeall.g file. If you take it out of the machine and put it in a PC, you shoudl a number of folders like "filaments", "gcodes", "macros", "sys" and "www" . You may not have all of the folders. But the important one is "sys". Inside there you will see all the relevant files that the firmware uses. Starting with bed.g then config.g etc. Further down is homeall.g and that's the file that runs when you press homeall. So check that and see if it bears any resemblance to the file that you think is your homeall.g.
EDIT. IGNORE THIS - SEE MY NEXT POST DOWN.

Ahhh. That's where you are going wrong. You should go to "settings" at bottom left, then click on "system editor". There you will find the homeall.g file. Right click and edit it.

pushing the home all button on the web interface, and running the homeall.g file manually from the g code list does not yield the same result.... is there anywhere else that the Home all button could be grabbing instructions from?
Actually, they all do that... If I manually run the file from the Gcode list, the axes slam into the end stops with no regards for the end stop switch... If I use the buttons on the web interface, they home properly.

@steve-lynch You shouldn't have any homeing files in the gcode list. These are files that you print and reside in the "gcodes" folder on the sd card. The homing files that are run when you do homeall or homex or homey etc, reside in the "sys" folder. You edit these as I've described above.
If you want to upload a file to that .sys directory, you go into "Settings", pick the "General" tab and there you will see a big button that says "Upload File". Press that then navigate to the file you want and it will get uploaded to the .sys directory (where it belongs). DO NOT upload homing files to the gcode folder (or if you do they will only get ignored unless you try to print one).

Ugh! It was that simple.... I feel like such a dumb ass! I actually should have known that... I've set these up before.... I'm soooo sorry!
So should I delete all of those gcode files from the gcode list? not in system editor, but the gcode list?
Those don't belong in that directory, do they?
-
sorry, you were typing while I was... problem gone... Thanks so much guys!
This was a painful, yet informative exercise! I'm really embarrassed.
-
@steve-lynch Don't worry about it. I'm just glad we got there in the end - I was beginning to doubt my own sanity there for a while.
Yes you can delete any homing files that are in the gcode list. Obviously don't delete anything that is in the "sys" folder.
-
Glad you guys figured it out.

I was working out of the system settings for the first 2/3 of this project, because most of the files were correct... I just somehow migrated to changing files in the gcode directory a few days ago, so basically everything we discussed since saturday or sunday was being changed on files that did nothing... lol. I cleaned all that out. I'm literally as we speak screwing together a railcore I ordered all the parts for... So this will definitely help me out, as I understand a whole lot more than I did a couple weeks ago... and.... It's fresh in my mind. You guys are Legends! Thanks!

@deckingman @Phaedrux Hey Guys, can you explain what's wrong with this portion of my Home all? It's the "go back a few MM" G1 X5 Y5 F600
The homing works correctly except for this portion... It goes to X/Y max quickly, and slams into the end of the Max... I've tried a few different variants, but with the same result. I followed the example from here: https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter
The individual homing files work fine, and omitting this single line from Home all completes without incident.. I've tried to sort this one out myself, but I'm afraid It's right in front of me, and I'm just missing it..
G91 ; relative positioning
G1 Z5 F6000 S2
G1 S1 X-400 Y-400 F10000 ;move quickly to X or Y endstop and stop there (first pass)
G1 S1 X-400 F6000 ;Now do a fast move just on X and detect end stop
G1 S1 Y-400 F6000 ;Likewise YG1 X5 Y5 F600 ;go back a few mm
G1 S1 X-300 F360 ;move slowly to X axis endstop once more (second pass)
G1 S1 Y-300 F360 ;then move slowly to Y axis endstopG90 ;absolute positioning
G1 X190 Y150 F6000 ;go to first probe point
G30 ;home Z by probing the bed; Uncomment the following lines to lift Z after probing
G91 ;relative positioning
G1 Z5 F100 ;lift Z relative to current position
G90 ;absolute positioning -
I thought it was that line, but apparently it's not... it seems to have to do with the Z homing... I'll go back through the older posts above real quick..
-
Ok, I'm tanked again... I've tried nearly everything above..
End stops are correct, home x, homey, homez work right... what did I screw up now?
-
I'm wondering if your motor directions and coordinate system is correct.
Can you verify for me that the 0,0 origin point is in the front left of the print bed?
-x movement goes to the left, +x to the right
-y movement to the front, +y to the backAlso where are the end stops in relation to x and y movement?
-
aaaaaaah! I didn't need that extra G90 prior to moving to the first probe point!
-
That g90 should be ok there.
-
Yes, all directions are correct, end stops are correct, I was putting it into absolute mode which was pissing it off! It seems fine now.
manual G code moves are as expected!
If I put the G90, it runs off to x300 y300+... if I remove it, it simply goes to the first probe position and homes Z as it's supposed to.. If it's working, am I ok to leave it out?
? -
If that move doesn't work as an absolute position move than I suspect that your coordinate system is not correct.
-
Go through the movement section here again and do the motor direction test to verify that they are going in the right direction.

Also, can you post your config.g and homing files as they are currently?
-
All of the other homing files work fine however.. the buttons move everything in the right direction, what would you suggest I check? I mean if literally every direction I input is moving the right way, what would / could be off? wouldn't all homing files move in the wrong direction?
