Cura SD print on Printrbot simple not working..making a big glob...

Recommended Posts

So I almost exclusively print from an SD card so that my laptop is free. Up until a few days ago everything was working fine. But now when I start a print a slice in cura my Simple just goes to the from left corner and just proceeds to print a glob in the corner. It hasn't done this before and I can't seem to find any info about it. Does anyone have any suggests or thoughts as to what might be causing this?

Are you saying Cura is different than other slicers?

Or that Cura changed recently? It shoiuldn't have changed recently.

yes, Cura does that. It extrudes faster than most extruders can possibly extrude so often it's not a problem but sometimes with hotter nozzle temp (due to temperature overshoot) or due to softer filaments I get the big blob.

I *always* sit patiently at the begining of the print and grab that blob with my fingers as it starts the print.

Some slicers are smarter and wipe the blob off along the front edge of the bed.

No, I'm saying that cura used to print perfectly without fail for me. It would home X and Y, go up 15mm then slowly move down to the middle or the bed. But then maybe a week ago it started to move Y out as far as possible, homed X then would just start the print at that location. I have tried multiple files and each ends up being a glob about 1 inch long by 1/8 of an inch wide.

I don't know how to describe it other than that it just prints a big glob in a very small area instead of starting the print like it used to.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
