So im little bit stuck so any help is heartly appreciatet. Not completely new into 3D printing but far away from experienced.
Here is what happened:
0. bought a defect ender 3 V2 (as second device where i also want to engrave with someday) and :
-Changed mainboard with the skr mini e3 v2 which i grabbed cheap
-Added the crtouch and second z axis kit
-Rewired the display
-Deepcleaned and relubricated
-Changed the feeder tube completely to a capricorn tube(on eyesight length)
-Rewired really everything (for easiert replace between laser and printing head in future)
-Changed to metal extruder feeder
-Added a emergency stop in between power supply and printer
-Changed the print bed to glass/swapped to thicker bolts to hold bed
Then I compiled marlin 2.0.7 a la github ticket. Which works so far on first sight.
Homing and probing via octoprint and display is working. Next i want to get the printer printing its possible best even tho its allready quieter than my qidi at least while moving..
Therefore next theres the calibration phase ahead:
-Setting z-offset
-Flow/feed rates
-Motor steps
-anything missing after changing almost everything?
And there are coming some other questions before going on.
Q0. Is there any newer/better firmware i’m missing?
Q1. Do i have to set the new bowden length in marlin?
Q2. Where best to put the bed holding clips?
Q3. Any way to support both leveling, manual + mesh, in perhaps software?
QX. Any pitfalls i could circumstance from beginning from the ender 3 v2 veterans?
As mentioned any meaningfull help is greatly appreciatet.
Hope your all doing fine.
There is a much later version of marlin available from the marlin website but you would need to learn how to setup the config files for your printer and control board.
One of the first things I did when i got the ender3 v2 was the install a magnetic bed and spring steel plate. I could not get a print to stick to the glass bed that was included with the printer.
Thanks for your reply!
I did compile my own firmware, and marlin 2.0.7 is working perfectly fine so far with all changes from the github ticket even with cr touch.
I tested to go to a newer marlin version this morning. Had no luck and from 2.0.9 they even stopped supporting the e3 v2 board completely. Only the e3 v3 gets supported configs from there. Missing icons and other problems occured on mine with finding homing in z. Just probed few times in mid air.
Jumped back to my 2.0.7 firmware and everything fine again.
Thanks for the tip with the leveling g-code! I will implement for sure in slicer.
And to give it a direct extruder is also pretty wise, did you use a custom one or do you have any reference?
Have some spare direct drive which i will try to pinch on. Will give feedback.
Since the thermistors arrive i will give print feedback!
The extruder i used is the creality sprite pro, use the model with the ender 3 kit, this has the correct mounting brackets and cabling.
You will have to increase the extruder steps to approx. 490 and reduce the retraction to < 4mm. these settings are from memory as I have not used my Ender 3 V2 for some years. My current printers are an Ender 3 S1 Pro, K1c and K2 combo.
I have a spare BTT E3V3 baord from my original old ender 3.
