i have
[c]T0 ; select tool 0[/c]
at the gcode file header. firmware is the latest 1.18.1

i have M116 issue too.

in my gcode there is a part

[c]M104 S205
M109 S205
M116
[/c]

but duetwifi does not wait for temperature to raise to 205 and continues to print…
what is a way to command printer to "wait for temperature 205. continue printing when 205 reached" ?

Hi!

i need some strategical help: i have delta printer with single extruder.
there is a need to print first layer with 2 colors.
my item is rectangle with some letters on it.

rectangle is one color. font - another. option to print rectangle and print font on the top does not work in this case.

i have created rectangle with "holes" for letters
and i separately have letters.

i can not figure out how to combine all this in the slicer, so that it would first print letters, i change filament and
print the rest.

many thanks!

Hi!

I suggest to move "Edit" and "Delete" buttons to right side of screen (after "Last modified" column)

Suggested elements (columns) order in macro page

1. Play (run)
2. macro name (file name)
3. Size
4. Last modified time
5. edit
6. delete

this will improve usability

Well, i have created 3-step macro and it works. For convinience i created a folder called Nozzle change
I wonder, if it is possible to wait for an "anykey" within macros? than i can combine steps 2 and 3.

David, maybe this can be included in your factory settings in a separate folder.

Step 1

;=================================================
; 		Nozzle change macro 1/3
;=================================================
;source article 	https://duet3d.com/wiki/Calibrating_a_delta_printer

M561 			; disable mesh compensation
M208 S1 Z-3 		; temporarily allow Z moves down to Z=-3mm
M564 S0			; to allow movement lower than where the firmware thinks Z=0

M117 Please manually lower head to a paper height

Step 2

;=================================================
; 		Nozzle change macro 2/3
;=================================================

G92 Z0 		; define that height as Z=0
G1 Z15		; Command the nozzle up 15mm 

M117 Please attach Z-probe

Step 3

;=================================================
; 		Nozzle change macro 3/3
;=================================================

G30 S-1 		; probe the bed without resetting the Z=0 position
M500			; store results

M117 Complete 

Hi!

i faced an issue of "too many steps" after i change nozzle.
because nozzles are different in size - each time it is changed i need to
re-calibrate whole system
10 steps "Measuring the trigger height"
than manually edit config-override.g

is there a faster way to do the change?

also i have seen some discussion on tool change but did not find solution there .

many thanks!

maybe this http://www.omc-stepperonline.com/09deg-nema-17-bipolar-stepper-motor-2a-46ncm-17hm192004s-p-122.html
plus some adapter ?

@davidbates:

Just wanted to stop in and say this is looking fabulous. I've been looking for a solution to house multiple tool heads with quick disconnects and this looks perfect for that.

A couple of features I'd really like to see:
1. A single connector on the back that can be universal for all the different tool heads (hot end, laser, cnc, touch probe, etc)
2. That single connector is a magnet style both for safety and for a quick change.
3. I'd like for the rods to carry current either for the connections needed (there are 6 connectors) or for fault-tolerant break detection.
4. a purple color from osh?

Again really good work and thanks for sharing. If there's a beta or early product tester program sign me up.

i vote for magnetic quick change too. as for connector - if i change tool, how than board will differentiate which tool is connected?
if it does then firmware may automatically adapt for the tool.

@dc42:

I intend to document how to retrofit a self-resetting polyfuse as implemented on the new 1.02 PCB revision, but it may be several days before I can do this.

David, what is causing this issue? thermistor? than i would like to protect my DuetWiFi board from failure and solder in a self -recovering fuse in thermistor wiring.
What voltage \ amps (or wattage) fuse should be used?

or it is faulty hot end?

thanks!
