@alxndr
I'm lost want happening if it not showing 220 , 220 homed !!! .
I take it you are using more or less the config.g file you posted at the start.
**** o.k , just looked at your config.g and found the problem ****; Endstops M574 X1 S1 P"xstop" ; configure active-high endstop for low end on X via pin xstop M574 Y1 S1 P"ystop" ; configure active-high endstop for low end on Y via pin ystop M574 Z1 S1 P"zstop" ; configure active-high endstop for low end on Z via pin zstopM574 X1 S1 , what does this mean ?
Xnnn Position of X endstop: 1 = low end, 2 = high end.
Snnn Endstop type: 0 = active low endstop input, 1 = active high endstop inputS1 is correct for it works.
Now for the bit you have wrong X1 and Y1 , which means it homes to the left / front , X1,Y1 this need to be changed to X2,Y2 home to the right / back.**** IMPORTANT BIT ****
it is homing right and back because the motor directions are wrong like I said yesterday .; Drives M569 P0 S1 ; physical drive 0 goes forwards <---- M569 P1 S1 ; physical drive 1 goes forwards <---- M569 P2 S0 ; physical drive 2 goes backwards M569 P3 S1 ; physical drive 3 goes backwardsMake P0 and P1 motors S0 not S1 , like this.
; Drives M569 P0 S0 ; physical drive 0 goes forwards <---- M569 P1 S0 ; physical drive 1 goes forwards <---- M569 P2 S0 ; physical drive 2 goes backwards M569 P3 S1 ; physical drive 3 goes backwards -
@peter247 so for the x1 and y1 under endstops, i want them to be x2 and y2 ?
so they should be high end, active high?
the thing is that they do home to back right physically. so im not sure?
as for the important bit....making motors s0 would do what exactly? make them properly go forwards? ill be honest...im a little confused lol
so right now, when i home x and y, they go back end and right side. so back right. isnt that the way they should go? im sorry....im new to all this so im just trying to understand lol
-
so for the x1 and y1 under endstops, i want them to be x2 and y2 ?
so they should be high end, active high?Yes and yes ... Low end mean home left , High mean home right , it tell you machine where the end stops our.
making motors s0 would do what exactly? turn in the other direction.
Before it was told that the end stop was on the left , but went to the right and hit the end stop on the right .
in a way it would work as it was now , but you would get a mirror of it.
so right now, when i home x and y, they go back end and right side.
Yes , but it thinks it is going to the left and hitting a end stop on the left.
TWO WRONG ARE MAKING A RIGHT . -
@peter247 so i made the changes you recommended and both x and y crashed because they went towards the left side which has no endstops. had to panic
i played around with everything and ended up reverting back. even when i use the buttons for x and y to go left by 10 or wtv...when i click the left direction buttons, it goes right. i get that something isnt right. but no idea what to do. i tried your suggestion but it doesnt seem to work at all. just crashes so i have to shut down. when i go +10 it moves left and when i go -10 it moves right.....i just dont get it...i feel so discouraged. any ideas?
-
You're close. Here are a few rules that you must follow and then the one thing you might need to change to get it all to work.
X0 Y0 MUST be in the front left corner to match the slicer and CAD coordinate system. X- to the left, X+ to the right. Y- to the front, Y+ to the back. Doing otherwise is asking for mirrored prints.
The end stop position is physically located on your printer, so you have to have it configured correctly to match. You have the endstops at the high end of travel, because 0,0 is the front left, and the endstops are at the rear right. 235,235 (or whatever the max travel ends up being) so M574 MUST be X2 and Y2.
Now that we know where the endstops are located and which direction of travel things should be going, we can change the homing files to move towards the endstops. Since your endstops are at the high end, the homing moves MUST be in the positive direction.
Now that we have all those MUSTS out of the way, there is one thing left to change to make it all work. The direction of the motor rotation. Defined M569 S1 or S0.
To test which way they should go it's simple.
First, with the printer off, physically move the print head to the middle.
Turn on the printer and edit config.g and set it like so:
M569 P0 S0
M569 P0 S0Now when you reboot, go to the gcode console and send these commands
G92 X100 Y100 ; that tells it that the X and Y are basically in the center and will allow you to move them
Now send G1 X10
The print head should move 10mm to the right. If it doesn't, we need to change M569 P0 S0 to S1.
Now send G1 Y10
The print head should move 10mm to the back. If it doesn't we need to change M569 P1 S0 to S1.
And now after making any changes you should be able to home and it should move towards the endstops, stop, and set the position to whatever the max travel is.
The last thing to do will be to set your M208 maxima values to what they ACTUALLY are and not what creality has advertised.
To do that, turn off the printer. move the print head to the front left corner where you want 0,0 to be. The nozzle just at the corner of the printable area.
Now turn on the printer and send G92 X0 Y0
Now send G1 X300 H3
That will move the print head to the endstop and when it stops it, the current X coordinate should be what you use to set your M208 X maxima.
Now use G1 Y300 H3 to do the same for the Y axis.

@alxndr
repost your config.g file / homeall.gYou haven't changed the motor direction like this ?
M569 P0 S0 ; physical drive 0 goes forwards <---- M569 P1 S0 ; physical drive 1 goes forwards <----or you haven't set the homing file correct ?
My guess is you have chosen the Ender 3 configurator , But the ender 3 are like the cr10 , it home at 0:0 left , down .
So to home you say go minus upto 220mm left , but the ender 5 home right so homes with a plus value.
( A ) you are not using my Homing file
( B ) you haven't changed the motor direction .
( C ) Both -
@Phaedrux thanks for all this! ill try tonight after work when i get home. i remember maybe trying something like this but when i tried to move left it wouldnt go all the way. maybe i missed something. it would stop half way...
also, when you say to manually move the print head to the center, does it have to be perfectly in the center? im not sure i can do that just by eye lol
-
@alxndr said in Duet 2 Wifi + BLtouch issues on Ender 5 pro:
does it have to be perfectly in the center?
No, it's just to keep it away from the ends of the axis.
-
@Phaedrux so something is wrong. I did everything you said to do. and im still getting everything in the wrong direction. The one thing that is weird is that after changing x1 and y1 to x2 and y2, the movement buttons still dont work in the right direction BUT only move to the left just a little bit and then wont continue. Im not sure if this makes sense.
ill post my config.g with how it was before i made your changes as well as my homing files. if you could help, that would be amazing.

It's only going to start working right when everything is changed. Go through the steps I describe. It'll work.
M574 X2 Y2
Homing moves in positive direction
Then test your motor movement directions -x to the left, +x to the right, -y to the front, +y to the back. Change M569 S to get those directions.Then homing and jogging should work.
-
I'll leave it to you !!!!
He is still using negative homing , still got the wrong motor direction and using low end homing.
I think he is only changing one setting at the time and saying it not working.
How do you get it wrong when you give someone a full set of correct homing file and tell him step by step what to change in the config.g file.
I guess it is true ? you can get a horse to water , but you can't make it drink. -
@Phaedrux thanks so much for explaining and for your patience. I'll give all that a try today and report back.
-
so i got everything homing perfectly now! great guide, thank you!!
as for my axis limits, does this make any sense to you? the advertised is 220x220x300
the bed physically measures 235x235
and when i run the commands you send me after manually bringing the print head to 0,0, these are the numbers i get (below).
also, do i have to home the printer every time i reboot it? it keeps turning the buttons orange and sometimes says not homed when i try stuff...
thanks again!

@alxndr said in Duet 2 Wifi + BLtouch issues on Ender 5 pro:

Yes. When the power is off the motors can't be guaranteed to hold their position, so you need to rehome the printer.
Those axis maxima look pretty good
-
@Phaedrux but the build plate is actually 235x235 though. Are my numbers still ok even though?
-
235 based on what?
What you measured was what the nozzle can actually reach if you placed 0,0 at the corner of the reachable area. -
@Phaedrux if I measure with a tape, it's 235mm by 235mm. The actual glass bed I mean
-
And can the nozzle reach all that area?
-
@Phaedrux yes I can. All of it. Basically the edges are right where the nozzle goes until. That's why it's confusing to me. It should be 235 not 228.8 lol am I missing something? Everything else seems to be fine now. Just that mystery is left
