EDIT:
I have Firmware Version 1.17 on my PanelDue and will Upgrade to the latest. The macros are only supported from 1.20 in.

MacNite

Sorry for the late response.

I tested the code and it works absolutley flawless!

Thank you for your help!

MacNite

up!

I really want this feature - or a workaround - as well

MacNite

I do not think your ideas help. I tested them but they did not improve anything...

but I found the mistake!

You know....in programming you are often start counting with 0....not with 1. So my x Stepper is not P0.1 but P0.0....

Oh my gosh...works now.

Maybe some of you have seen my post of trying to built a calibration routine for the CR3D Idex machines.

https://forum.duet3d.com/topic/21803/calibration-routine-for-dual-extruder-printers

This thread did not get much tracktion...probably due to the kind of complex nature of such a routine. So I'll try to break down the problem into smaller chunks.

The "newest" problem is the user-interaction.
After completing the z-calibration the user should be asked, if he is satisfied with the results. Otherwise it should be repeated.

	; start z-calibration routine
while z_satisfied = false
    M291 P"Put a piece of Paper on the built plate" R"Calibration of z-Position" S2
    T1
    M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 1" S3 X0 Y0 Z1
    G10 P1 Z{-axes[3].position}		; set z-offset of Tool1 to value from last calibration
    M500 P10                        ; safe Tool1 offset
    G1 Z5
    T2
    M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 2" S3 X0 Y0 Z1
    G10 P2 Z{-axes[3].position}		; set z-offset of Tool2 to value from last calibration
    M500 P10                        ; safe Tool2 offset
    G1 Z5
    M291 P"Remove Piece of Paper" R"Calibration of z-Position" S2

	; start test print for z-calibration
    ;M98 P"z_test_print.g"				; Print z-calibration lines

	; ask user if he is satisfied
	M291 P"Are you satisfied with the z-calibration results or should this step be repeated" R"Calibration of z-Position" S2
	; If M291_input = yes
    ;    z_satisfied = true
    ;else
    ;    z_satisfied = false

Is it possible to get a "feedback" and or yes/no-buttons with M291 or is there any other way of "user-interaction"?

Hey guys,

at the moment I am working on a dual extruder tool together with @CR3D . The first prototype of the tool is working right now - the tool is comparable to a Startasys or Ultimaker 3 Nozzle-Lifting assembly but the actuation is done by a servo. At the moment I am stresstesting and performing little improvements.

I want to use / built a firmware-integrated nozzle-offset-routine for both hotends - in this I want to calibrate the x, y and z offset of both nozzles.
To calibrate the offset of both nozzles I want to use a routine similar to the one by BCN3D and Craftbot.
At first I want to move the nozzle - close to the bed using a PanelDue and/or webInterface.
After that is done for both tools a simple z-offset test print (i.e. 20x20mm 1-layer square) shall be printed.
Afterwards the user shall be promted if the z offset is ok. If yes: the routine continous. If no: the routine goes back to z-offset adjustment.

The same is done for x-y-offest - just with using "line" extursions like the ones on the picutre:

I tried to built a flow chart of the things I want to do:

Writing the gcode and doing basic configuration is not a problem for me.
My main questions are:

How can I safe the new Offsets to the config.override?
How can I create "buttons/popups" in DWC and PanelDue as an "interface" for the calibration routine"
Is this even possible within RRF3.x or is something similare integrated?

Have a nice day,
Max

MacNite

Thanks for your response!

For the time beeing I'll try some drivers I have laying around (without SPI) to just test it....maybe later on I'll return to the SPI-question. Mostly because I don't know how to compile duet firmware on my own and have to read that up

Have a nice day,
Max

@gloomyandy

Thank you for your input.
Regarding M98 P"config.g" and the individual stepper settings: DWC / Console does not report an error.
I removed the "settings" behind the ":" so I only have 1 setting per z-stepper. I.e.

M350 X16 Y16 Z16 E16 I1

As you thought this was not the culprit.

I tried both regarding M569, with only H, with only V, and leaving it away. No change in behaviour.

M915 reports this:

16.7.2021, 21:37:02	M915 P0.1
Driver 0.1: stall threshold -10, steps/sec 200, coolstep 0, action on stall: none

M569 P0.1 reports (after using the V50 values from homex.g)

16.7.2021, 21:44:53	M569 P0.1
Drive 1 runs in reverse, active low enable, timing fast, mode stealthChop, ccr 0x00053, toff 3, tblank 0, tpwmthrs 50 (187.5 mm/sec), pwmScaleSum 35, pwmScaleAuto 0, pwmOfsAuto 95, pwmGradAuto 11, pos 424

What happens when I try to home the motors: They just hit the printer frame and don't stall. They move completely fine but "stall detection" or whatever the trigger for sensorless homing is does not work.
I tried to use

M915 X Y S-120 F0 H200 R0

but even with these values the print head keeps hitting the frame until the "end" of the travel I defined in homex.g is reached and than reports "insufficient axis homed".

I looked at https://teamgloomy.github.io/sensorless.html but could not find any "helpfull" information.

Hey guys,

I think I need your help once again. A few weeks back I built a CoreXY using an Duet 3 6HC without Endstops for the XY-Stage.

CoreBot V2 on Instructables

I was really impressed how realiable that worked compared to the last time I tested this a few years ago. So I choose to use the same for the new version of my CorEssentials CoreXY printer using the Duet 5 Mini+.

This does not work at all. The stall detection does not work. Not at all. The printer performs the "stealthchop calibration moves" and the first homing pass. But thats it. After that it throws out the error "G28 X homing failed" as well as "G28 X Error: G0/G1: insufficient axes homed".

I assume I am doing something wrong...here is my config and home x:

I already read through multiple threads in the forum to find a solution and tried the following:

update to RepRapFirmware for Duet 3 Mini 5+ 3.3 (2021-06-15) ; Including the necessary IAP update to install this firmware
included the "stealthchop calibration" in the homing files
changing the sensitivity of Stall Detection to S-64
made sure the steppers are skipping steps and the belts are not slipping
using M913 X50 Y50 before the stealthchop calibration
using 30-70% in M913
using only X-Stepper in M913 (instead of X & Y)
using only X-Stepper in M569 (instead of X & Y)
changing M569 V and H values (V=50 equals to 185mm/s, 1 to 2000)
using different speeds for homing (3000 mm/min to 18000 mm/min)
leaving out "stealthchop calibration"
using different feed rates for "stealthchop calibration" (1000mm/min & 6000mm/min)
reducing x & y jerk from 1800 to 600 mm/min (M566)
reducing acceleration from 10,000 to 1,000 mm/s² (M201)

I really do not know what I should to anymore...on the Duet 3 6HC it was very easy. Just adjusting the S-Parameter in M915 command. Any Idea why this is not working on the Duet 5 Mini+?

Thanks for your help,
Max

MacNite

Thank you for your replies!

@dc42 Thank you for the info.

@Lbi No, it is not because of the endstop position, it is the other way round. I want to "limit" the movements additionally ot the endstop position without decreasing the built volume significantly.

@sinned6915 very nice idea! I think this would be a very helpful feature.

@fcwilt I could move the build surface back, but that would "decrease" my total built volume. ATM I am trying to maximise it.

@OwenD Very nice Idea! I think that will be the way I'll try it!

Hey guys,

at the moment I am building a new machine. Due to the design of the z-axis and the Tool head there are 2 corners (marked red in picture) which the print head is not able to reach because it would cause a crash with the z-axis top mount.

Is there any way in RRF3 to restrict movements into this area so the printhead won't move there?

Thanks for your help.
Max

MacNite

Thank you!
Is there any "feedback" from the M291 command I could use in conditional code?

M291 P"If you're satisfied with the z-calibration results push "OK", if z-calibration shall be repeated push "cancel"" R"Calibration of z-Position" S2

So I can coordinate if thh z_satisfied variable should be set to true or false according to the user-input?

This thread did not get much tracktion...probably due to the kind of complex nature of such a routine. So I'll try to break down the problem into smaller chunks.

The "newest" problem is the user-interaction.
After completing the z-calibration the user should be asked, if he is satisfied with the results. Otherwise it should be repeated.

	; start z-calibration routine
while z_satisfied = false
    M291 P"Put a piece of Paper on the built plate" R"Calibration of z-Position" S2

    M500 P10                        ; safe Tool1 offset
    G1 Z5
    T2
    M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 2" S3 X0 Y0 Z1
    G10 P2 Z{-axes[3].position}		; set z-offset of Tool2 to value from last calibration
    M500 P10                        ; safe Tool2 offset
    G1 Z5
    M291 P"Remove Piece of Paper" R"Calibration of z-Position" S2

	; start test print for z-calibration
    ;M98 P"z_test_print.g"				; Print z-calibration lines

	; ask user if he is satisfied
	M291 P"Are you satisfied with the z-calibration results or should this step be repeated" R"Calibration of z-Position" S2
	; If M291_input = yes
    ;    z_satisfied = true
    ;else
    ;    z_satisfied = false

Is it possible to get a "feedback" and or yes/no-buttons with M291 or is there any other way of "user-interaction"?

This thread did not get much tracktion...probably due to the kind of complex nature of such a routine. So I'll try to break down the problem into smaller chunks.

Is there any way to store the tool offsets after doing
a) z-offset-calibration
b) x-y-offset-clibration

M500 does not safe it. I tried something like that (writing to a file on the sd-card).

T1
M291 P"Move the Bed up using the buttons until the paper slightly graps on the nozzle" R"Calibration of z-Position- Tool 1" S3 X0 Y0 Z1
M28 tool1offset_z.g 			; generate file for z-offset Tool1
G10 P1 Z{-axes[3].position}		; set z-offset of Tool1 to value from last calibration
M29

There are 2. Problems with this:

the file "appears" in the print-files folder which is not really nice for our customers.
It writes

G10 P1 Z{-axes[3].position}

into the file and not (i.e.)

G10 P1 Z-2.5

Any ideas / solutions / different ways?

thanks for your help!
