Simple Metal stops moving and just extrudes a blob
I just got a Prntrbot Simple Metal the other day and I'm trying to figure out all the stuff it can do. Unfortunately, I've been unable to print anything because it keeps stopping in the middle of a print. what it will do is, just stop moving in the X and Y access, and keep feeding PLA into a blob until a pull the power. Here's a picture of it http://imgur.com/jX381ET
It happens randomly at different points in the print, but so far it has done it on 3 different models and usually on like the third layer in a different spot. That tells me it's most likely not a corrupt STL. when I check the error log it says
Code:Recv: Error:Line Number is not Last Line Number+1, Last Line: 365 Recv: Resend: 366 Recv: ok Send: N366G1 X94.757 Y93.944 E27.86820*123 Recv: ok Send: N367G1 X95.065 Y93.636 E27.88993*112 Communication timeout during printing, forcing a line Send: M105 T0
But I believe the communication error is because I have unplugged it. The most info I can find on this is a USB cable losing connection, but I would imagine I would hear the windows USB disconnect sound if that happened...
I HAVE successfully managed to print 2 things, which came out kind of crappy, but I can't even begin to get into fine tuning settings if I can't even get it to complete a print >.< Heres my cura settings

1/ have you created a printrbot support ticket ? They answer within the day usually.
2/ thjis seems more linked to your link to the printer than the printer itself.
3/ do the motors seem hot ?
4/ have you tried to autoprint from a sd card ?
5/ Your gcode file is incomplete. Have you tried to read what's in the file for lines 365 and over ?
6/ what's the hotend temp when your blob is created ? is your printer trying to get back to target temp ?

I'm wondering if my problem lies in the motor heating up, that might explain the inconsistency. But if the extruder motor got too hot, would that cause the X and Y to stop moving, and the extruder to just push like 5-10 pulses of PLA into a blob? I'm trying to get a video to better explain what's happening but the machine isn't cooperating and I dont have the patience or a set up to sit and record a full print....

Her'es a video of it doing what I'm talking about https://www.youtube.com/watch?v=8-7l...m-upload_owner

Hi,
I was about to say it could be residual ooze, but hearing in your video that the extruder is working...
Just out of curiosity, what speed have you set ? Try reducing to 30mm/s for starters.
Have you put in your slicer a height max (stop printing over this height) ?
Do you have an end code (like go to X0,Y0) ?
If the motors are hot and it is none of the above, it might be board or motor issue.

I beleive this is the end code
Code:;End GCode M104 S0 ;extruder heater off M140 S0 ;heated bed heater off (if you have it) G91 ;relative positioning G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed} ;move Z up a bit and retract filament even more G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way M84 ;steppers off G90 ;absolute positioning ;{profile_string}

Yep, normal end code.
Cura is supposedly good, I personnally use Simplify 3D.
I'm sorry but I don't have the knowledge to help you troubleshoot further. You should try to test your motors and/or contact PB. I'd be interested to hear what's the final answer.
