printer keeps pausing during print?
-
awww, it was obvious, missed the G out at the start of the homez code!
printer is still printing, 24hours in it's 48% done
onc this finishes I'll set it going again tomorrow and see if this fixed it!
p.s. I bought a "PanelDue - Integrated" too... how do I make it work? I thought I just had to plug it in... had a google but can't find any info

If it was supplied with a 4-way cable then you should just be able to plug it into the PanelDue port on the Duet. if it was supplied with a ribbon cable then you plug that into the CONN_SD header on the Duet instead.

screen came with the 4 pin cable... I tired that but it didn't work - the screen looks a bit like it's crashed - I'll try to get a photo later on
print head still keeps pausing when it moves between different areas
I don't know if it's relevant at all but it seams to over retract when it finishes printing too, not always but a couple of times I've had to push the abs back in because it's so far out the gear doesn't touch it
I'm a bit lost with the pausing thing
(p.s. I tried with a couple of different files to make sure it wasn't me/cura causing it)
-
finished next print today... still doing the same thing..
checking g-code console I see...
5:32:39 AMFinished printing file taptop x4 at90mm.gcode, print time was 9h 28m
5:32:18 AMWarning: Tool 0 was not driven because its heater temperatures were not high enough or it has a heater fault
8:04:52 PMM32 "taptop x4 at90mm.gcode"
File taptop x4 at90mm.gcode selected for printing
no other errors, no idea if this is relevant, watching print head/bed temps while printing they look pretty constant
this is the gcode file for the last print (17meg)

I've looked through. nothing looks odd to me

That is probably caused by printing either using gcode generated by Cura or with absolute extrusion selected in the slicer, and retracting filament in your slicer end GCode using a G1 E-xxx command. You need to insert either M83 or G92 E0 before that G1 E-xxx command.
To track down the reason for the pauses, we need to see the GCode around the point where it pauses while moving between areas.

I'm struggling to sort out the bit of g-code which is causing the problem, or the g-code at about the same time
I've made a new g-code, I took a 20mm test cube, duplicated it and shrunk them tiny (my idea bing there's less g-code for me to deal with)
it still pauses when it finishes a layer, moves to the next cube and then pauses before it prints (then when it finishes it pauses before it moves back to the 1stc, etc. etc.)
here's the start of the g-code

Thanks for the sample file.

Which firmware version are you running?
-
Are you certain that the pause occurs on the first layer, when moving from one part to the other?

do my extruder settings look ok? - I keep thinking it's as it retracts/extrudes as it moves from one area to the next?

I also increased the printing speed in cura so it could be that.... idiot me should have only changed one thing at a time!(I'm trying to get these parts printed before the weekend so I can use them)

shouldn't flavor be reprap? or doesn't that matter?

M84 S30 ; Set idle timeoutI tried printing that GCode file and I get only slight pauses, during which the extruder is retracting or re-priming. You are using a lot of retraction. So I agree that the problem is probably related to retraction. Can you watch a gear or pulley on the extruder drive while it is printing?
Your extruder acceleration in M201 is a little low (500), but not low enough to cause this problem. But I guess it's possible that you have a non-printing character in the M201 or M203 line that's causing the extruder max speed or acceleration to be read as very low. You could try re-typing those lines.
You don't need the double Z values in any of those lines, because the Z axis as a whole uses only one set of values.

there's no gear/anything to see when it's printing
I could try printing again without the heatsink/fan on to test the idea out?
I increased the extruder acceleration to 750
and decreased the retraction length to 2mm ( hadn't realised it was so high)
I'll see how that does for the next print
thanks for all the help

Did you resolve the problem?
