@Phaedrux hey again! would you have any suggestions for start and end gcode? this is probably the very last thing i have to do until i can finally print. thanks!

@mitch would you happen to have an example of start and end gcodes that i could look at? im trying to set mine right now. Thanks!

@Phaedrux so I did that. But it only probes 3 while saying it can't reach some points.

@mitch I don't get how we have the same printer and yet we have different values for axis limits.

@mitch just out of curiosity, how and where in comparison to your nozzle is your bltouch mounted?

@mitch Thanks for this! i think im pretty much set right now. The only thing im messing with is the bltouch probing points. I'm having a little trouble with that....trying to get 4 points to probe but it keeps telling me it cant reach the points. i basically set start at x10 and end at my limit which is x228.8 but i realize thats for the nozzle...not the bltouch. so im not sure how exactly im supposed to set that.....

@Phaedrux oh wait...the x cant go ALL the way to the left because of the bltouch!!

now last thing...trying to set 4 probing points....using this: M557 X20:208.8 Y20:203.5 P4

But it only probes 3 points? the results in the console say "probed 12 points" but its actually probed 9...any ideas with that?

@Phaedrux I cannot jog past that point physically but I'm wondering why that numbet is different from the actual measurement

@Phaedrux no it's because I'm physically blocked lol 0,0 (bottom left) is basically at a physical limit.

So I'll ask again because I'm a little lost. If my bed physically measures 235x235, why is it that my number is 228.8? Shouldn't it be 235? That's what the bed actually measures if I measure it with a tape. And the nozzle won't physically go beyond the printable area.

@Phaedrux when I bring it to 0,0 I can no longer move it Left or front. But it should go to 235 becauae that's the length of the actual bed. But it only goes to 228.8.

@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

@Phaedrux if I measure with a tape, it's 235mm by 235mm. The actual glass bed I mean

@Phaedrux but the build plate is actually 235x235 though. Are my numbers still ok even though?

@Phaedrux

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!

@Phaedrux thanks so much for explaining and for your patience. I'll give all that a try today and report back.

@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.

@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

@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?

@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

@peter247 it does home to the right back. yes i used your homing files. not sure what value it shows though as i dont remember. I would have to check tonight after work.

if i do need to fix it, is it an easy fix? just so that i have them ahead of time.
