Thank you all very much for the fast Help! I have contacted my reseller and He gave me The warranty contact Formular which i already sent to duet3d. Now i am waiting for the reply!

Thank you all for the messages,

I made a temp tower because I used the 245 degrees I used on my ender 3, but it turns out that 235 give me the best results.

I use a bowden extruder, maybe I should reduce the retract and look where it gets me. But in my mind the more retracts is preventing blobs, because there is not to much material, so why reduce it to reduce blobs?

Do you have a good file for retract distance calibration?

The ripple I got away by changing the place for the printer and putting some rubber sheet under it, this helped a lot.

Thank you all for the advices, the thing with the Speed is interesting, I will try that on the weekend.

I use 245°C for printing of the PETG Filament. Is this already High for PETG?
Speed at the moment is 60mm/s
Retraction at 6mm
Retract speed at 50mm/s

Extruder is a Bondtech BMG
Hotend E3D V6 Full Metal

Seems that to be okay?

Hello Community,

I have build up my BLV MGN Cube (XY-Core) with a Duet2 Wifi and now I get everything to Work. I did the PID Calibration of Heatbed and Hotend, Calibration via 20mm Cube and now I have printed my first Benchy. I get some Issues and have no Idea how to go on, can you help me with your experience? Material is PETG from "DasFilament". I run this Material on my Ender 3 already and have quite good results.

Here the Pictures:

Ripple

sudden little Overextrusion

fine Stringing

You have any ideas? Thanks a lot for everything.

Tobias

I have sent the warranty contact formular a few days ago, has it arrived? I didn't get a confirmation email yet or any other reply.

Thank you all very much for the fast Help! I have contacted my reseller and He gave me The warranty contact Formular which i already sent to duet3d. Now i am waiting for the reply!

I switched x and y and have still Drive 0 Error Message. So is the driver broken? Can i use the second extruder driver instead of Driver 0?

Disconnect the stepper giving the error and see if you still get the error message.

Frederick

Thanks Frederik, i did it and it shows still the error Message with driver 0. Does this mean the driver is broken?

This is how i did it.

Thanks for The reply

Hey Community,

I have my first Project, a BLV MGN Cube with the duet 2 Wifi board. I get the board at my birthday in august and now was the first test drive this week. The problem is that I get the error "short-to-ground reported by driver 0", whenever I want to home X or Y axis and I get strange movements and loud noises.

I don't know how I got there, because I did everything according to the manuals, I test the wiring to identify the coils of the stepper motors (bluerolls) and connect everything like in the discription of the board. At the first run directly I have horrible noises from the motors and directly this error. The movement is very, the only words to discribe this is "hopping" and "chaotic". Was anyone of you facing a similar problem and can help me?

Z-Axis works fine.

sincerely
Tobias
