So i bought this used and it printed beautifully a couple prints. On the third, it stopped extruding. I can push filament through so it wasnt clogged. I found a bad wire on the E cable and replaced it with a set from amazon. Then i found a bad wire on the e extension cable. Still wouldnt work. I purchased a new 4.2.7 board and loaded the Mriscoc firmware for it and still didnt work. I replaced the motor and checked my voltages on the board and they were good according to a video i found. Still didnt work, so i purchased a different set of cables and got it working. Set up my e steps and calibrated everything on the firmware. Started printing a 4 hour print and it stopped extruding mid print again! I put my E cable into the x motor and the x cable into the extensiin going to e and tried moving them (after it heated to 205) using the move axis. Neither one would move now. I removed power and turned it back on and now x works but e does not… im lost since everything has been replaced. I thought it was the board so i sent it back to amazon and got a new one and still the same issue. I have no idea where to go next with this except maybe replaceing the screen but i doubt thats my issue. I did a continuity test through all the wires and they showed good using a fluke meter. Please help before i trash this thing and go with a different brand which i really dont want to since i like the Creality brand. Thank you in advance
