I could use some help

droftarts

@mac I thought you were going to try and stick to one thread? Or at least post new threads with more specific thread titles?

Posting the files that you need help with would also go a long way to helping people help you. In this case config.g, homex.g, homey.g, homez.g, and/or homeall.g if you use that.

Anyway... see https://docs.duet3d.com/User_manual/Tuning/Bed_origin

@droftarts I don’t know how to add new questions to an existing thread. Otherwise, I wouldn’t have done this.

I need to go take a pill. Later.

@droftarts I wish I knew how you were doing that.

droftarts

@mac When you are posting text in code blocks, the three backticks that mark the beginning and end of the code need to go on a line on their own. I've edited your posts to fix this.

eg

I wish I knew how you were doing that.

I'm an admin, I can do ANYTHING!

@droftarts thank you so much, I'm going to try to learn how to do that.

@droftarts X-255? Y-255? my bed's 220 by 220! where is this coming from?

A Former User

@droftarts not anything, my friend, but you can do amazing things, that's for sure.

I used to build houses. that was amazing until I had my accident.

alankilian

@mac said in I could use some help:

X-255? Y-255? my bed's 220 by 220! where is this coming from?

It's -225 not -255

Your bed is 220, so you need to move slightly MORE then 220 to make sure you've hit the endstop in case it's way at the other end of the travel.

So your bed is 220, move -225 and you will always hit the home switch.

droftarts

@mac Assuming you don't want to rewire the machine, or turn it around, the first thing you need to do is define the endstops as 'high end' or 'maximum' endstops. Change the following two M574 lines from X1 to X2 and Y1 to Y2:

; Endstops
M574 X1 S1 P"io5.in" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin io5.in
M574 Y1 S1 P"io6.in" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin io6.in

Now when the nozzle homes against the endstops, it will set X and Y to the maximum value set by M208, rather than the minimum:

; Axis Limits
M208 X0 Y0 Z0 S1 ; set axis minima
M208 X220 Y220 Z240 S0 ; set axis maxima

But at the moment, your homing files will make the X and Y axis move towards the LOW end, rather than the HIGH end, so we need to flip these. In homex.g you currently have:

G1 H1 X-225 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X5 F3600 ; go back a few mm
G1 H1 X-225 F360 ; move slowly to X axis endstop once more (second pass)

These need to change to:

G1 H1 X225 F1800 ; move quickly to X axis endstop and stop there (first pass)
G1 H2 X-5 F3600    ; go back a few mm
G1 H1 X225 F360  ; move slowly to X axis endstop once more (second pass)

So that the X carriage goes to the maximum end of the axis, hits the X homing switch, backs off 5mm, then moves to touch it again.

You need to make the same changes to homey.g and homeall.g.

If you need to adjust where X0 Y0 is, you change the bed area in the M208 commands. Do the above first, and if you need more help with this part, let me know.

@mac it should be a colon : between values, not a semicolon ;

@alankilian thanks, man, childhood dyslexia strikes again

A Former User

@droftarts okay, so, now we're talking hard-core editing of the actual config files, correct? Versus using RRF to "edit" them, correct?

So I'm guessing I can just "look" at the files, and high light what I want to change, or delete, and hit ENTER, and that will make the change, then "SAVE" and that will save the whole file with the changes?

And the changed file will become the instructions used? (There's no reloading that needs to happen?)

A little confirmation (or correction), will go a long ways right about now.

Mark

droftarts

@mac Yes, you can edit the files in DWC. Sorry, I should have made that clear. Make sure you make a backup, as any changes will only exist on the SD card.

Alternatively, now that you know you have maximum endstops on X and Y, you could go back to the Configuration tool and change it there.

Did you know you can load the config.json file from a previously created configuration back into the Configuration Tool, and all the settings you made previously will be applied? That can help if you have a lot of changes to do.

@alankilian nice clarification, Alan Killian

@droftarts I did not! but I think that's how i'll approach this humongous job-a-rooney.
