That is not flat.  Wow, that is bad.  

RE: Prusa Mini Clone from China

I believe that is saying the left side  of bed is lower than the side the z Axis and the extruder is on.

@rockytoptim

I think you are right.  

RE: Prusa Mini Clone from China

@rockytoptim

So basically the part about not being square and I should look into that first?

RE: Prusa Mini Clone from China

Just by putting a strip under the right side of the electronic case it git much better:

Yes.  That is something easier to fix.  The bed would have to be replaced if it is not flat enough.  You can check this with a straight edge.

Did you read my question about the Bowden tube when using a full metal hotend? Kan I just use the existing tube without modifications?

No e-steps adjustments or something alike? The path from extruder to nozzle will be longer if you don't cut the bowden tube a bit.

sorry english in isn't my language so I may wrote bad.

anyway this is my trianglelab heatbreak

Actually I am quite happy with the standard extruder, hotend and heartbreak have been working fine also, just want to swap the heartbreak in case I want to print ABS, but am looking for info if I need to do something with the bowden tube or e-steps.

RE: Prusa Mini Clone from China

@fernando-t-2

Same here.  I have printed ABS with PTFE tube.  No issues so far.  

RE: Prusa Mini Clone from China

@fernando-t-2

steps must be adjusted only if You replace the extruder, changing the heatbreak only does not require any firmware change.

RE: Prusa Mini Clone from China

@turro75

OK, That is good news, but since the path to the nozzle will be a bit longer as the Bowden Tube does not go as far in the heartbreak als the original one I would expect it needs some adjustment. I will do a measuring anyway, extrude 100 mm of filament and measure it after marking the distance on the filament.

RE: Prusa Mini Clone from China

@cwbullet

Did you print ABS with the standard heartbreak with the PTFE lying? Data is dangerous right? The PTFE lining will start to burn at ABS temperatures. Or do you mean that you have printed ABS with a replacement all metal heatbreak and the standard PTFE bowden tube without adjustments? 

RE: Prusa Mini Clone from China

@fernando-t-2

It hasn't happened yet.  

RE: Prusa Mini Clone from China

Anyone running firmware 4.3 on the clone already and if so any issues?

RE: Prusa Mini Clone from China

@fernando-t-2

I have tried 4.3.0 rc1 first. Fan test didn't pass. Rc2 and final work well.

RE: Prusa Mini Clone from China

@fernando-t-2

I have and it works.  

RE: Prusa Mini Clone from China

Ok Great, then I am going to flash it tonight also.

If you have Bondtech extruder, Z calibration will fail. When printer go to Z calibration and go up to Z max, just put 4mm alen key between X carriage and Z motor carriage.
