Just spotted the answer in the doc''s, yes the ZB connector needs to be jumpered.

VB,

If removing the Z slave axis the doc says to jumper the ZB connector is that true?

VB,

Thanks David.

I'll be giving that a shot before long then.

ampapa,

This is on a heated bed with PEI… I hadn't thought about the print coming loose though.

Overnight shutdown...

I have the need to pause a lengthy print.

Since I've never done this before I was wondering what the process for implementing it is. Do I simply "Pause" the print and shut down the printer and laptop?

I assume I should home the machine before restarting? How does it know what line of code to start from when I fire up the printer again?

Any "how-to" would be great if there is one..

Thanks.

ampapa,

After homing, assuming I'm using -.01 as posted above my control panel shows Z at -0.1 that assumes a deflection of the piezo if I understand you post correctly. The -0.1 is then adjusted based on baby stepping and printing of the 1st layer and ultimately could be less or more and that actual number should be reflected in the config.g file, correct?

So in Slic3r I need a Z offset that reflects that actual number +/-… I think I understand.

Thanks,

One additional follow up question on setting the Z axis positioning.

[c]G31 X0 Y0 Z-0.1 P600[/c]

If the piezo is effectively able to find Z=0 then why the need for an offset in the config.g file? Is this to force the probe to go below the bed surface?

When the probe touches the bed surface shouldn't that effectively be the Z=0, no offset is needed from that point forward?

Thanks.

Can I adjust where the print head goes on my machine when hitting the "Pause Print" button?

Thanks.

ampapa,

Thanks for the quick feedback DjDemon.

I ran a first test with the unit and it seems to be working correctly.

In my homing files (homez/homeall) what would that look like now, something like the following?

ORIGINAL homez.g

G91                ; Relative positioning
G1 Z-350 S1 F300   ; Move Z down until the switch triggers
G1 Z2.5 F300

G1 Z2.5 F150

NEW homez.g

EDIT

Just wanted to close the loop on this and post my working Z homing file.

G1 Z4 F400              ; lowers bed 4mm to avoid dragging nozzle over the bed

I'm wanting to replace my Z axis home switch on my CoreXY, Z home's at the top.

M558 P0 X0 Y0 Z0 H5 F120 T6000

I think I need the following in my config.g,

M558 (P1/P5) I1 R0.4 F300 X0 Y0 Z0
G31 X0 Y0 Z-0.1 P600

I'm using the v2 PCB in a NC configuration. I'm also unclear what the difference is between the analog/digital and what it is used for? Does the board still need to be tuned in a digital usage or is that irrelevant?

I also am a little confused on the homing sequence. I think I need to home X/Y then move to the center of the bed and run a G30, is this correct?

Appreciate some help.. thanks.

ampapa,

So this will probably get me flamed but …

I recently built a CoreXY and had no experience at all with 3D printers but was able to follow the wiki and ask questions in the forum and was able to get the Wifi working without much hassel.

https://www.duet3d.com/wiki

and specifically the wireless connectivity

https://www.duet3d.com/wiki/Getting_connected_to_the_Duet_WiFi

Maybe its the gCode your struggling with? It also sounds to me like you bought something that you couldn't afford based on how many times you've repeated how much you spent.. we all paid a premium price for a premium product.

Since you're now invested in the product I would probably change the negative attitude and approach things from a more positive side if you expect forum users to help you iron out the problems you're having. Also, I would keep in mind this is a "Family" business and probably nothing like those big companies that you deal with all the time in your engineering world.

just my two cents… have a Merry Christmas!

@vbtalent:

…
Assuming a 305x305x305 machine should it be the following is order important?

M208 X305 Y305 Z305 S1 ; Set axis maxima
M208 X0 Y0 Z0 S1 ; Set axis minima

I then can remove the G92 commands from all the home'ing config's?

VB,

OK, thanks… S0 is for maxima and S1 is for minima in which case order is irrelevant.

M208 X305 Y305 Z305 S0 ; Set axis maxima
M208 X0 Y0 Z0 S1 ; Set axis minima

So, if in my config.g file I have an M208. You're saying that it is effectively setting the G92 of the machine?

My current M208 command is the following which I'm now thinking is incorrect?

M208 X0 Y0 Z0 S1 ; Set axis minima

Assuming a 305x305x305 machine should it be the following is order important?

M208 X305 Y305 Z305 S1 ; Set axis maxima
M208 X0 Y0 Z0 S1 ; Set axis minima

I then can remove the G92 commands from all the home'ing config's?

VB,

Yes, just a note when I was knocking out issues that my Z Axis wasn't homing.. fixed it though.

Commenting out the G28 command in the Slic3r code seems to have worked… the G1 Z5 F5000 ; lift nozzle move happened and the hot end heater kicked on. this really doesn't make sense..

However the test print was a total failure, lol! Nothing stuck to the table… and so I've found my next problem.

VB,

I have a single hot end and a bed heater. I ran a tuning for each using an M303 H0 S120 (bed) and an M303 H1 S285 (hot end E3D). I then added the following to my config file.

; Thermistors and heaters --------------------------------
;Bed
M143 H0 S120                        ; Set the maximum bed temperature in c-default is 110c
M305 P0 T100000 B3974 C0 R4700      ; Bed thermistor
M307 H0 A203.7 C745.2 D2.6  B0	    ;Set bed to use PID mode

;E3D
M143 H1 S285                        	    ; Set the max temp of the hot-end in c-default is 280c
M305 P1 T100000 B4725 C7.060000e-8 R4700	; E3D thermistor
M307 H1 A324.6 C134.8 D3.7  B0				;Set E3D to use PID mode

I believe if you run an M303 H1 or M303 H0 it will show you last tuning information.

The wiki has good info. in it… https://www.duet3d.com/wiki/Tuning_the_heater_temperature_control

VB,

That would go in the config.g file as your Bed setting for the heater… here is mine.

Hope it helps..

M307 H0 A203.7 C745.2 D2.6  B0	    ;Set bed to use PID mode

I'll try adding the T0 to the Slic3r gCode and see if things change this morning.

I see there is a place for it to be added in Slic3r in the "Start G-code" section as a permanent item.
