HELP! Duet 2 WiFi Configuration and DWC Upload???

[PCNoobNeedsMajorHelp]

@phaedrux

So I'm back.

3 questions.

1. I swapped my extruder stepper motor with a .9° pancake. What settings do I need to change in my config file?
2. When I pause a print it crashes into the front left corner. What do I need to change? the G90 command?
3. I am ready to set up the BL Touch. How do I set it up in the config file? It's physically installed on the fan shroud, but I don't know what or if I need to set the offset. I also don't know where to plug it in on the duet. I have the Black and White wired to the Z Endstop. Where do I plug the yellow red and blue connector into?

ERROR
Something went wrong while parsing server response

^ I keep getting this when I try and upload screenshots of my files. Until I get it fixed let me know what you need and I can relay the info.

Thanks,

Fixed it. Here are screenshots of my files as they are currently set

For the extruder changing to 0.9 degree from 1.8 degree means that you would double your steps per mm. If you were already using a 0.9 motor you wouldn't change anything.

For your pause.g if it's hitting the edge you can slightly adjust the G1 X0 Y0 to be G1 X10 Y10 to give it some space. But if it can't safely reach x0 y0 then your M208 maxima might be a bit off.

For the BLTouch you need this in config.g

; Z-Probe
M307 H3 A-1 C-1 D-1                     ; disable heater on PWM channel for BLTouch
M558 P9 H5 F120 T6000                   ; set Z probe type to bltouch and the dive height + speeds
G31 P500 X0 Y0 Z2.5                     ; set Z probe trigger value, offset and trigger height
M557 X15:215 Y15:195 S20                ; define mesh grid

You'll need to check config-override.g to any M307 H3 lines and delete them if they exist.

And you'll need to create two macro files in the /sys folder for deploy and retract commands to control the pin.

When I was checking the new e-steps I noticed it was skipping so I tried to loosen/tighten the tension, and then I took out the filament and the same thing happened. Does this mean this particular motor doesn't have enough torque to support the extruder?

[Phaedrux]

Do you have to have the specs of the motor? It may need more current than the previous motor. The rule of thumb is to use ~60-80% of the rated motor current.

So if the motor is rated as 1amp (aka 1000ma) then you would use 600 to 800 ma in the M906 command to set the current.

Oh also should the tip of the BLTouch probe be at the same height as the tip of my nozzle in relation to the bed?

[PaulHew]

@pcnoobneedsmajorhelp No, or you risk crashing the BLT
IIRC the bottom of the main body of the BLT, not the probe should be 4-5mm higher than the nozzle

[PaulHew]

@paulhew

[PaulHew]

Basically when the probe is extended it should be lower than the nozzle and when retracted as illustrated 3-4mm higher than the tip of the nozzle.

[PCNoobNeedsMajorHelp]

@phaedrux

Ok. So.

-I changed my current to 1200 for the extruder motor
-I changed my pause.g file.
-I changed the confi.g file for the probe, deleted the M307 H3 line in config-override.g, created the deploy and retract macros, and wired everything up correctly. The tip of the probe is about 3mm above the tip of my nozzle. (Do these changes stay the same for the 2.05 firmware version?)

What's next?

-I feel like I read something about setting the Z probe height in the config.g file or in bed.g or homeZ?
-How do I set up the mesh bed compensation?
-I removed the original Z endstop, is that right?
-and lastly, do I have to change any settings in Cura?

Yes you will need to calibrate the trigger height of the probe. Basically telling the firmware how far the nozzle is from the bed when it triggers. Without this it doesn't know where Z0 is.

You also need to tell it how far away the probe is from the nozzle in X and Y.

The instructions are here: https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe

-How do I set up the mesh bed compensation?

Once the probe is working see here: https://duet3d.dozuki.com/Wiki/Using_mesh_bed_compensation

-I removed the original Z endstop, is that right?

Generally, yes. Homing Z would be done with the probe instead. You will need to edit your homing files to use the probe now.

Instead of G1 H1 Z-400 you would have

G1 X150 Y150 F6000 ; move probe to center of bed
G30 ; probe the bed to determine Z0

-and lastly, do I have to change any settings in Cura?

No

@pcnoobneedsmajorhelp
Z Probe
Read these, they are useful.
https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Commissioning_Testing_RepRapFirmware_Num_3
and all of this or most of it.
https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Dynamic_test

Do you want to post your config.g for a sanity check?

P.
EDIT: @Phaedrux to the rescue!

[PCNoobNeedsMajorHelp]

@phaedrux

Which homing files? I cant find G1 H1 Z-400

[Phaedrux]

The -400 was just an example. In your homeall it's this section:

G1 H1 Z-315 F240
G90
G92 Z0

And in your homez it's this section:

G1 H1 Z-315 F3000
G92 Z0

Replace that with this:

G1 X150 Y150 F6000 ; move probe to center of bed
G30 ; probe the bed to determine Z0

Now in my example it's using x150 y150 but you can adjust that so that the probe itself is in the center of the bed.

And maybe after the G30 you want to have it move back to a parked position you can add

G90 ; absolute positioning
G1 X10 Y10 Z10 ;  move to parking position

@phaedrux

When I sent M401 and M402 command nothing happened so I deployed and retracted it by physically clicking ton the macro files. Is that ok? (is it because I'm using RepRap2.05?)

In the Dynamic Test section it says to home all. Am I good to do that without it crashing?

That's what this test is for I guess. I just want to check and make sure everything's correct)

I'm following step by step and it hasn't said to enter any values yet for telling the printer the position of the probe yet with offsets and such.

Here's what I have so far
Config.g

@phaedrux

So when I went to disable axis limits with M564 S0, it didn't work. same thing with the M401 and M402 commands, what do I need to do to fix this?

Thanks,

M401 and M402 don't work, but your macro files do, then that means your macro files are either named incorrectly or aren't in the right folder.

deployprobe.g and retractprobe.g should be in the system folder, not in the macros folder. M401 and M402 actually just call those macros.

That's in the measuring X Y offset section.

I don't know what you mean by this.

[PCNoobNeedsMajorHelp]

@phaedrux

So when I try to disable the axis limits, I can control them by the DWC but they aren't actually disabled because I cant move the printer head will my hand freely, as if the motors are still engaged.

I figured out my X and Y probe offsets for G31. I read somewhere that the heater cartridge could possibly interfere with the BLTouch. Would that happen with the distance that the probe is at, for me?

Do my homeall.g and homez.g look? good?

Here are my DeployProbe and RetractProbe files

Code


Code

Should I delete the deploy probe and retract files from the macros folder?

Thanks,

Well yes, M564 won't disable the motors, it just lets you command the motors with the jog buttons even though you haven't homed yet.

It looks like you're missing the .g file extension on your deploy and retract files.
