Voron 2.4 3MB6 §EB config issues.

Titus A Duxass

@jay_s_uk Wait - my mistake! The Z is homing, it's just going extremely slow! Should be done about Tuesday.

@Titus-A-Duxass said in Voron 2.4 3MB6 §EB config issues.:

M574 Z1 S2 ; configure Z-probe endstop for low end on Z

You should remove that line. Endstop mode S2 is used only when the Z probe is used to home axes other than Z.

Please post your homeall.g and homez.g files.

Error: Probe was not triggered during probing move
Error: Probe was not triggered during probing move

This happened with the Z at about +100mm

@Titus-A-Duxass can you post your config as well just so we can see your probe settings?
btw, what probe arrangement are you using?

Titus A Duxass

@jay_s_uk

Okay, I switch it off and manually lowered Z, it now homes. I think there maybe a time out issue.

@Titus-A-Duxass said in Voron 2.4 3MB6 §EB config issues.:

G1 X40 Y15 F6000 ; go to first bed probe point and home Z

so really you want to change that to the centre of your bed, taking into account the probe offset (i.e if the centre of X is 150 and the probe is 10mm to the left of the nozzle you would move to 160)

same goes for homez

@Titus-A-Duxass said in Voron 2.4 3MB6 §EB config issues.:

M350 Z64 I0 ; configure microstepping without interpolation
M350 X64 Y64 E64 I1

i would stick to x16 rather than x64. you don't gain anything

@Titus-A-Duxass said in Voron 2.4 3MB6 §EB config issues.:

F120

your probe speed is to move at 2mm/s. thats ok for a second pass but your first pass probably wants to be quicker. you can set a first and second probing speed like this F1200:120

@Titus-A-Duxass said in Voron 2.4 3MB6 §EB config issues.:

M584 Z0.1:0.5:0.3:0.4

you don't need this again

Titus A Duxass

I really appreciated your help this.
Now you are stretching my 61yr old brain.
I have a bed that is 300 x 300 so centre will be 150 x 150 - you can see the probe/nozzle set up in the photos.

So I simply overwrite 64 with 16 in config.g?

jay_s_uk

@Titus-A-Duxass you'll also have to divide your steps per mm by 4

for the probe point you'd move to X150 Y125

Sorry but you've lost me there.
Which file is this in and what am I editing.

I'm going to need a beer after this!

jay_s_uk

@Titus-A-Duxass the M558 F value in config.g

Again, you've lost me. Unfortunately I have zero knowledge of G code and configuration. I have been following a youtube video to set this lot up.

Titus A Duxass

@jay_s_uk

Okay, so F1200 is the first pass speed and 120 the second pass speed.

my line now looks like this:

M558 P5 C"^io3.in" H5 F1200:120 T6000

jay_s_uk

@Titus-A-Duxass

these lines

M350 Z64 I0 ; configure microstepping without interpolation
M350 X64 Y64 E64 I1 ; configure microstepping with interpolation
M92 X320.00 Y320.00 Z400.00 E1746.16 ; set steps per mm

change to

M350 Z16 I0 ; configure microstepping without interpolation
M350 X16 Y16 E16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z400.00 E436.54 ; set steps per mm

your Z steps were wrong for X64 which is probably why your moves were so slow and it was erroring out after 100mm (as the machine had thought you'd moved 400mm which is greater than your Z height)

Titus A Duxass

This post is deleted!

jay_s_uk

@Titus-A-Duxass because we're setting x16 rather than x64, so the values need to be dividing by 4 as we're using 4 times less microsteps

Titus A Duxass

This post is deleted!

Titus A Duxass

@jay_s_uk Okay, I think I understand. I need to do a bit of reading about microsteps.

@jay_s_uk My config.g now looks like this.
