I noticed some clicking sounds and saw that the x axis belt and ribbon cable collide while printing
. I also noticed that the Bowden tube chain scrapes against the metal frame
How can I fix this?
How can I fix this?
There is a reason a lot of J1/J1s owner modify their machine 
I think it’s just “bad design”.
I’m printing the top riser right now. Also the filament carrier inside, new bowden tubes, filament guides and so on!
I hope all this improvements do exactly that, improve the machine! 
And i removed the sheet metal under the tube chains, they are bad by design too.
This chain was always jumping over the most front screw from the sheet metal 
I thought with buying the s model all the start-up difficulties are gone, but no!
Positive thing… the new “all metal aluminium hotends” and the fan on the backside, are great!
Yeah. Any lid riser is almost a must have.
And @ZT_1234, this is a good thread on common tweaks. A lot of the easier ones are worth doing. I put felt tape on the frame under the chain belt for clicking. For hotend related stuff, I recommend just getting the all-metal ones from Snapmaker now, though there’s a good thread on DIY also.
Is there any way to elevate the extruder skipping? I don’t notice under extrusion in my prints but I do often hear the extruder skipping teeth
As in, you hear tiny clicks while extruding? Do you also get runout errors?
For this, all my skips and runouts while printing were solved by all-metal hotends, as far as pla goes. First homemade, then trying out the Snapmaker ones. Same result basically.
The exception is I still sometimes get hard skips (real clog) immediately at the beginning of the print. One thing that solved this was preheating the bed before starting the print, since the glass bed takes much longer to heat than the hotend.
Sometimes this is from doing a filament change. Something about the filament unload seems to leave a blob in the heat break, but not always. Still haven’t exactly figured what recipe is best for avoiding that.
