*.fff file for SainSmart Coreception 3D printer?

Wed Aug 26, 2020 7:40 am

I need *.fff file for SainSmart Coreception 3D printer with direct-drive extruder. I downloaded the file from SainSmart's website at http://wiki.sainsmart.com/index.php/101-91-501 but the file may be for bowden feed extruder, not direct-drive extruder.

With a 7mm retraction distance, I assure you the profile hosted on that wiki page is not for a direct drive extruder design. The XML of the file even says that the profile is a copy of the CR-10.

You'd likely be better off starting from the S3D stock CR-10 profile and changing just a few things. I've listed how I'd go about it below.

1. Help > Configuration Assistant > Creality CR-10 profile
2. G-Code tab > Z height: 400 > 330
3. Extruder tab > Retraction distance: 5 > 1
4. Layer tab > first layer height: 120% > 100%
5. Layer tab > first layer width: 150% > 100%

I have under-extrusion problem. I'll try increasing the extrusion multiplier.

The extruder has stepper motor turning a large gear that pushes filament out the nozzle. I don't know the gear ratio.

I think that the X-limit switch is missing.

You can adjust your extruder's steps/mm by following the steps in this post: viewtopic.php?t=1189#p4290

I would contact the manufacturer for assistance with acquiring missing hardware.

How can I write starting and ending scripts that do these:

Starting Script
Home all axis
Lower the build platform 10 mm
Turn on cooling fan
Preheat build platform and extruder
Wait for preheating to be done
Raise the build platform 10mm
"Draw" a line along front of build platform tp prime extruder
Start printing

Ending Script
Home all axis
Turn off heaters
Turn off cooling fan
Lower build platform 25mm
