Cura print sequencing

Posted · Cura print sequencing

Hi,

Just a quick question: I have a small print and the upper portion of it is two columns.

The trouble is the tops of the columns are coming out as messy blobs. I witnessed what was happening, which is two layers of the each column being printed without any cooling time in between. The order of printing was occurring according to the sequence numbers in the pic.

So even though I have set the minimum layer time to be 8 seconds (and minimum speed to be "0") the result is still that there is printing onto the still very soft layer is just finished printing (with no time in between at all). The transitions 2-3, 4-5 and 6-7 are where this is happening.

I suppose the 8 second rule is still being obeyed for each layer (since the head needs to travel and print the other column), but the sequencing of printing looks to be completely undoing the whole point of the layer time setting for extra cooling.

Is there a way to combat this effect?

Thanks

    Hi. There used to be a setting to force cura to start each layer with the same model but it seems to have been removed. However, in the Travel section of the settings you can specify X/Y coordinates of a location and cura will start each layer as close to that location as it can so specifying that may solve your problem. Hope this helps...

    This was reported as a print-quality bug in Cura at least two years ago. Still not fixed, I see...

     

    Thanks for this information. It saves me further digging through the settings.

    This is a bit disappointing to have the software be as "unaware" as to do something like print onto hot molten material. That it has not been addressed after so long...

    Being a newcomer to Cura, I know nothing of the two year old bug report cited above but could you please just try specifying the layer start x/y location and see if it fixes your problem. Thanks.

    @Eldrick: I also have an Aluminatus, which works well with Slic3r.  I'm trying to get it to work with CuraEngine (part of Repetier Host) and the prints are garbage (bloated, distorted).  I started with the default configuration (which works perfectly with the CR-10) and tried to tweak it for the Aluminatus, but this approach is not working.  Anyone care to share a better starting point for Aluminatus settings?
