Simplify3D printer moves but doesn't extrude

After having enough of MC crashing on me and a need for more versatility, i decided to get Simplify3D.

Right off the bat with just using the preconfigured Robo3D settings, printer will heat up normally, but will skip the 3-point auto level and just does a single point auto level in the center of the bed then begins the print, however the printer moves along the path, but does not extrude. (it does extrude in jog/manual printer control, only when printing it does not extrude)

@Mike Kelly just need to add to the Gcode i assume?

 

also, I'm getting constant "cold extrusion prevented" in the comm terminal while printing, yet the printer is fully heated. My guess its has something to do with the toolset options.

 

What temp are you printing at? S3D's auto extrusion width is 0.48 for a 0.4 nozzle so you might need to increase you hotend temp. If your printing faster you'll also need to increase your hotend temp as the filament has less time to heat. Your using PLA I assume? Make sure you check/clean your hobbed bolt too.

 

I modded the firmware to print above 235C. But i was just testing it on S3D's PLA preset which is 190C hot end and 60C bed. Like i said when i manually extrude in S3D its fine no cold extrusion errors are thrown, only when printing i have the problem. The printer will move along the print path as it normally should, it just doest extrude.

 

I'd work with simplify3d customer support on this. No clue

 

Try print at 210C. That's what I print PLA at. It's worth a try.

 

Yeah, some problems I can help with! I was having this issue when I first got Simplify 3D. The problem was that I had "Preheat for PLA" on my Smart LCD Controller XXL configured to extrude at 210, while Simplify 3D was set to extrude at like 180. Simplify 3D would think it was hot enough, but my Smart LCD Controller XXL would stop it because it wasn't at 210. As @Galaxius said, try setting the profile so it prints at 210 and see how that goes.

As for the autolevel thing, set your gcode in Scripts > Start G-Code to the following:

Code:

G28; home X Y Z axis
G1 Z5 F5000; will lift Z axis by 5 mm
M565 Z-1; sets the offset for the auto-leveling mechanism by 1 mm
G29; runs auto-level

 

Yup! thats all it was. I forgot that when i updated the firmware it raised the minimum extrusion temperature to 190 i believe. Its printing now, but i have to offset the z axis a little cause its printing too close to the bed. And ill go ahead and try out that Gcode. Thankyou all for the help!

@bamhm182 should i not use M565 Z-1 if i already edited the offset under the Gcode tab?

 

Glad it's working. And honestly, I don't know. I got that gcode from the Simplify3D folks. I just noticed that line today. It works for me though, so I'd try it as is.
