Thank you, we're away again

Hi all,
My printer was working previously with no real issues but i decided to muck around with the zaxis to try and get more ridigity. Long story short i managed to damage some cabling in the process, didn't notice until a pungent 'blue-smoke' smell filled the room. Lovely. I've tested by moving the motors to other drivers and seeing them work as intended; the stepper driver on my X axis appears to be burnt out (and i can't really blame it).

I've seen that its possible to replace the driver using a heatplate and some other tools which i clearly don't possess; its also possible to use a breakout board style scenario and route to an external driver - i have a couple of options.

It has a second extruder driver which i'm never going to use, can i route the signal through that?

Cheers,
Shiven

Thank you dc42! (& deckingman!)

I'm now able to extrude plastic. That was a little tougher than i anticipated but have a position to launch myself from.

Thank you very much!

+@dc42:

G28 homes the printer. If you send G28 from the console, does the printer home correctly?

Alrighty, seems things are a little odd when i run that command (whee, getting somewhere!).

To explain the behaviour; its a corexy printer, running g28 when;

• the x/y endstops are triggered, only the z axis moves, homes normally and then stops.

• The X endstop is triggered alone, y moves back into position & rattles in place (trying to drive) once endstop triggered

• The Y endstop is triggered alone, x moves into position & rattles in place (trying to drive) once endstop triggered

It appears that those two endstops aren't stopping the x/y axis when g28 is run. Using the +10/-10 triggers however, the endstops are adhered to.

@dc42:

Please can you put that gcode on a file sharing site and then edit that last post to link to it instead of including all of it in that post. I am using a tablet and it would take me forever to scroll to the bottom of that post.

Does the G28 homing command complete before DWC says the print is complete? I am wondering whether something in your homeall.g file could be to blame.

I have updated the original post with a link to a paste site. The G28 command doesn't run or at least doesn't run fully. I'm not sure what order G28 actually runs in but i have heard a click (like the endstop un-triggering perhaps, or a relay potentially) prior to the print saying 'completed'. It all seems a little odd to me.

Cheers,
Shiven

What would be the preferred slicer for this board? I'm not exactly sold on cura, it just appeared to be everywhere at the moment so i thought i'd give it a shot. I used to use Skeinforge, but i was looking for something a bit more straightforward…

Cheers for the advice thus far!

I cut the other lines from the Gcode file - its my understanding it goes sequentially and never gets to the skirt anyway, so the issue would be up top. I can post the full file if desired - its just movements however.

HI All,
I apologise in advance, this will be a rather lengthy post to give all of the information i believe is relevant. I'm going to break it into smaller sections so you're welcome to skip over whatever is not relevant to the issue.

General / Issue Background
My Duet Wifi appears to be functioning as intended for the most part - i can move all axes, i can heat up heat bed and the stepping seems to be correct on all of them (or within tolerance at least). When i start a print, the system heats up the heat bed during the warmup phase, then heats up the hotend to the desired temperature. Both ht the correct temperature, as the first layer begins and it halts, says 100% complete Layer 1 of 198, Filament Usage 0.0mm of 1455.0mm. The Extruder has not moved at this time.

See here: http://imgur.com/a/9mq8H for an example of what occurs at the point of failure. A couple of things to note, the alert triangle at the top dissappears almost immediately - to the point that i have never seen it before and was just obscenely lucky to get it in that particular picture. Furthermore, the gcode console has no alerts or warnings - http://imgur.com/a/n4wXA. This has made this a difficult issue to track down as there are effectively no warnings as to why this has occurred.

Unit Background
Purchased approximately 12 days ago - have never managed to get a print out of it. Have managed to extrude plastic and have it move around however, never cnc/automatically. Have had other issues along the way, but nothing too drastic.

Running off an ATX power supply (12V).
Firmware Version: 1.18.1

Scratch this entire post, apologies, my board appears to be playing fine now. I plugged the connectors back in (after removing in the first step) and its not going crazy anymore.

I don't have a reason why, but its working. Apologies on that.

@dc42:

1. With the bed heater disconnected, does the bed heat LED turn on as soon as you apply VIN power to the board?
No, Light doesn't come on at all, unless heat bed is connected

2. Do you have the bed heater connected directly to the bed heater output terminals, or some other arrangement?
Connected directly to the output terminals.

3. What sort of bed heater are you using, and what VIN voltage are you using?
I believe it is a prusa heatbed mk 2. Red, standard aluminium(?) platter. Quite old (6 years?). VIN voltage is 12V off a standard ATX PSU (quite literally pulled from my old ramps board into my new Duet Wifi.

4. How long have you had the board? Your supplier may be prepared to replace it under warranty.
4 Days, though i imported it from England so its going to be difficult to do any sort of swap over. (I am Australian)

Thanks for all the help thus far, seems like i'm looking at doing a changeover.
