Hi there,

Despite a few bumps along the road, I have the printer built, wired, levelled, firmware and motor direction sorted and motion tested. So all good there. I've even been able to manually control extrusion so have tested filament in, heated, and expelled.

So.... printing time.

I know that SOMEWHERE in the settings there will be something relating to flow, or a diameter, or something like that, but I haven't been able to spot it yet. I've recorded a video of what's happening so you can see. The reason it starts off solid is that the heating was on full for a couple of minutes before I started recording, so plenty of molten filament in the nozzle.

What I am looking for is advice on what settings I might need to tweak.

Many thanks in advance for your help,

Geoff

FIXED: It was a simple fix in the end. I am using PLA and the extruder was set to 200 degrees C. By increasing the temperature to 215 degrees C the filament is nice and molten and can be extruded at the speed of printing.

1.I think you should level your bed again
2.Retraction distance:2~4mm
Retraction speed :40mm/s

Thanks for the reply William,

I can confirm that the bed isn't the problem (appreciating that it looks from the video that it slopes down to the back left). Retraction distance in Slicr is 3mm and Retraction speed is 40mm/s.

If I leave the job to run there is almost no filament coming out of the nozzle, so I am thinking it is an issue with the speed of filament feed? I have marked the filament and manually extruded and that seems to work correctly, therefore eliminating the possibility of incorrect voltage on the motors.

Any other thoughts?
