Diagonal speed limit raft print speed

Posted (edited) · Diagonal speed limit raft print speed

On my Creality Ender 3 printer, when rafts generated by Cura 4.0.0 are being printed, when the direction of the lines are diagonal using both X and Y motors, it seems I always get under-extrusion and ultimately jamming of my bowden tubes. It rarely happens at any other times in my prints. Observing the extruder I see the bearing slipping when the gear tries to push the filaments in.

 

Please note that I am using flexible TPU filament from AmazonBasics and that this issue may be unique to this filament and printer combo (stock, upgrade Bowden tubes incoming 😄).

 

Print speed I had was 20mm/s

Could someone with similar equipment investigate? Potentially better equipment might require higher speeds to encounter the same issue.

 

Edit: Also another thing I notice after going through all options is that inner wall speed maybe twice as fast than "Global Speed" set. My main issue is the rate the filament is being extruded.

 

I'd like to feature request that max extrusion speed be added per materials per printer.

 

Thanks!

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
