My FFCP has has been a workhorse for the last year and printed more than 2200 hours without much problems, thats almost 8.5 kilometer of filament.
So yesterday i wanted to give my printer a good maintanance and took it apart, in the process i wanted to change the plastic pulleys.
After putting it together again at first site this worked out great as i didn't had to change any of the original adapters, now when starting a new print the size of the printouts don't match anymore.

after some investigation I noticed that the plastic pulleys are having 17 Teeths and the new pulleys i used are having 20 which might be the issue. Today i ordered pulleys with 16T to see if this resolves the issue.

My question is if anybody else has tried to change the plastic pulleys and what kind of pulleys did you used (20T or 16T) as i don't seem to find those with 17T? Did any of you make changes to the firmware and how could i do this? Some advice would be welcome.

I changed the pulley back to the plastic one for the Y-Axis (only for the stepper motor in the right corner) and it doesn't seem to matter for that axis that i changed to 20T. Still i want to change all the plastic ones.

Yesterday I received the 17T pulleys and replaced the plastic ones I left on the stepper motors and started a new printout, all seems to work just fine now. so my conclusion, most pulleys would work for the corners, if you keep in mind to use 17T pulleys for the stepper motors.

If anyone can send me a video or give me some direction on this, I would really appreciate. My research points to replacing the x axis endstop so I ordered the part but the wires look to run inside the casing of the machine. I don't even know where to start to access these parts to replace them. I don't want to totally screw this up. Does anyone have a video they can send me on how to do this? I have been scouring the internet and can't find anything but I'm probably not writing it correctly.

While printing, my Flash Forge Finder quits feeding filament during the print.

I've tried several different test print .stl files. Some experience the same problem and then another time printing the same .stl it will print fine.

Troubleshooting so far:

Filament reel spins fine
Extruder does feed during loading and during start of print
I've changed print temperatures from lower to higher, does not change the the printer to stop feeding during the print
I've cleaned the PTFE tube and nozzle (.4mm nozzle)
I replaced the PTFE tube and nozzle with a new PTFE tube and new nozzle (.4mm nozzle)
I've checked the extruder gear and it looks clean. I've brushed it with a brass brush.
I've tried 3 different spools of PLA filament that 2 have worked previously. 1 spool was brand new out of the shrink wrap.

At first I was unloading then reloading filament and trying a test print.
Next I left the filament loaded. The only change was to leave the Flash Forge Finder where I stopped the print (sometimes 10% sometimes 23%, usually after 1 1/4 - 1 1/2 hour). Removed the print bed. Cleaned the failed print off the bed. Replaced the bed. Started a new test print, and the Flash Forge Finder started printing again. Feeding filament even though it had just stopped feeding during the previous print.

After changing the nozzle and PTFE tube it still has the same problem.

I'm stumped. Any suggestions?

Thanks.

Also, I followed this thread and it appeared to taper off without a solution also. Similar but different machine and different extrusion

I recently just switched my ABS Extruder to PLA, did one successful print in the PLA then on my second print, around 85% of the print being complete (about an hour in) the extruder stopped feeding filament and there was quite a distinctive clicking sound. I have tried upping the temps and pushing it through, also pulling it out and re loading but nothing is working. Anyone got any tips on unclogging.

Hi all - I have a Flashforge Creator 3 which has been running great for months now. Just installed a 6mm hardened nozzle and ran into problems. My right heater is now registering 1025 C when viewed on the STATUS screen and will not heat up. Possibly I shorted something out while disassembling/reassembling the nozzle assembly? I then replaced the thermocouple and swapped out the Right Extruder Circuit Transfer Board with a new spare. No luck. However, still able to print with the left print head. Before going forward replacing the heater and other component attempting to eliminate the problem, I wanted to check with those more knowledgeable than me. Any suggestions?

Hi All,
I am new to resin 3D printing and have a Flashforge 6.0 3D printer, and I have done everything that it says in the manual about bed levelling, but the prints stick to the FEP and sometimes on the FEP and build-plate! Any idea what I am doing wrong as it is driving me crazy!
Thank you in advance.
Tony

I've had my Adventure 3 for a couple weeks now. Everytime I go to calibrate the platform it says something totally different. I can get it perfect where an index card slides under with a small amount of tension. Then I run the calibration again and there's a gap the size of the Grand Canyon. Anyone know why it keeps changing on me or what I can do to fix this?

Hi all
I love my Creator Pro in combination with Simplify 3D - it's sturdy and prints endlessly - nearly endlessly.
However - my Creator Pro nears end of its life-cycle. I consider to replace it with the IDEX version - Creator Pro 2.
I'm fine with the slightly higher price tag - but I wonder, whether there is any reason not to upgrade, but replacing the creator pro.

Any reason you'd say, why I should not replace it with the idex version? Thnx for any hints, I have overlooked in the reviews and forum about the Creator Pro 2?
