@admin add again the source code would be highly appreciated

Being sure is quite difficult, how check the nozzle first, then if any screw related tot the hotend are loose.

@jcicare can you clarify the motherboard version and which fw have loaded?

@Dweeb1313 My two cents and I am currently quite happy with my CR6, learned a few tricks, as usually happens with 3D printers, I would still buy it.

There have been a few problems but the most recent FW solved it and the community CR6 FW gives also ways to plan upgrades.

This skrew is connected to a small spring, used to hold a plastic peace where the big spring used by the extruder is placed.tightening this skrew is not too important

The fw file is not shown, only the .gcode files are listed in the print menu. If copying the bin file the update doesn't start i would rename the file, reusing a fw filename is not possible, or reformat the sd with a fat32

The latest fw package available for download it is just a collection of the ones already released, no lt really an update.

Hi @MattySarv, did you check the voltage around the nozzle sensor?

Hi everyone, my CR6 is printing generally well but there is still more stringing that I would like, using PLA.

My retraction settings with CURA 4.8 are 6 mm distance, 25 mm/s speed.

Does any one has good results with different values?

@FPacios the sd reader issie had been common, not knowing how many Cr6 they sold i would say % level. I received a new main board but I didn't make the swap yet because in the meantime I started using an extension cable and this is still working well.

@Will-in-MN as already mention the card reader is often faulty. what can help, other than then the obvious replacement, is an extension with a externa reader. this trick can help to find a stable working point.

replace the board is for sure the best solution.
