The process wasn't difficult just time consuming. The mk9 came with a thermocouple that I had to replace with a thermistor and the rewiring was a pain.

Im getting sick of these hotends.. I might try that. Tried pla with the m9k? Or bronzefill, etc.

Yea I had problems with my OEM extruder too with tension and clogging so I replaced with an MK9. I don't know much about the E3D but make sure you don't buy a fake off ebay. You will have to change the steps per mm (I think) if the gears are different from the davinci, unless you use the davinci gear.

Was the process difficult? or is it just a simple hot end swap with maybe re drilling?

Make sure you are not chewing up the filament. There should be no shards of filament when extruding. When you try to extrude without the filament in the extruder does it still click? Take apart the extruder and look at the gear and idler, make sure they are aligned next to each other. Any clicking I ever had was from the filament being too tight against the gear and idler. Your stepper motor could be shot but I doubt it because they never go.

It does not skip with no filament in the extruder, Just the humming of the extruder. Those stepper motors are tough. I've watched it while clicking/skipping and the stepper motor was running smooth. And within seconds it grinds it up enough to where its coated and need cleaned with the wire brush. Its strange that there isn't a tension adjustment on these Da Vinci printers..

I've had nothing but problems with this extruder.. Is it difficult installing such as a E3D extruder? Anybody have experience?

It doesn't seem to be bent, the extruder with the idler by itself with the assembly removed does have plenty of grip.. By hand its impossible for met to stop it from feeding. Even with pliers it's very difficult. . Seems to also bite into the filament pretty bad, when taken apart and extruding. Leaving pretty deep bumps on the filament itself.

It should bite in to like that. Well I am clueless. Maybe somebody else might have ideas. I covered everything I know of and would suspect.

Thanks for the help, I've searched forms and experimented my self since its been down around 2 weeks ago .

Anybody else have any ideas?

Another user had this similar problem and found the release lever on the idler for loading and unloading was slightly bent and not allowing the spring to pull it fully against the filament. You might take a look at that. It should press against the motor gear with a little force when no filament is loaded.

Its ABS and I had problems awhile back so I soldered it and put some heat shrink tubing. The temperature doesn't go above or below 1 degree at any time including extruding. I've tried temps from 210 all the way up to 240 to try and get it to extrude properly. I've tried xyz filament and hatchbox stuff.

If it wont extrude in air, what temp is the LCD showing at the moment you try to extrude? The heater harness connector above the extruder is known to be cheap and is bad on some machines. It works when the head is in ceryain locations but when moved the connection opens enough thst the heater cannot maintain extrusion temperature.  That would be 190 or greater for ABS. If you are trying to print PLA give up. The 1.0 cant do it without extensive mods or the optional PLA head sold by XYZ for 100 bucks.

Your bed is too high or unlevel. Many of the beds are bowed and the middle is higher. Start a sample print. As soon as it starts laying thr purge line turn of the power. Move the head to the center of the bed. Turn each adjusting screw equal movements counter clockwise till you can just slip two pieces of paper between the nozzle and bed. Once you do that dont run the auto adjust, just start a sample print or your own print and see what happens.
