"One thing I did that improved the print quality to a point where it wasn't worth changing, was to put a piece of 1200 grit wet and dry paper on the bed and run the hotend over it a circular motion to get the bottom flat, they are kind of rounded as standard and don't push the layers down properly."

Perhaps making a .ZIP of everything and hosting it in MEGA or similar cloud service?by bolsoncerrado - General
That looks promising! I have a duet too.. Min d sharing a fw copy? Everything else stock?by bolsoncerrado - General
No I didnt, I refuse to believe a dirver I've never used is burned out for no reason....well, 3 in total. And the rest of the board works and communicates fine with the computer.by bolsoncerrado - Stepper Motors, Servo Motors, DC Motors

Well the board is not new, Id be surprised if at this point any broken traces (without moving the board) or cold points do appear (there are several fans near it). Is that even possible? Extruder was working fine to date.by bolsoncerrado - Stepper Motors, Servo Motors, DC Motors

Anyhow the pinouts are not stored in EEPROM and nothing related to it in regards of stepper drivers and pins...by bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
Wasnt there a setting to FIRST ERASE the whole contents of AT2560 before reflashing? For my own sanity's sake!!!by bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
Yeah Im using Octoprint to monitor and enable motors and terminal window shows no heating issues as I disabled them on Marlin straight. When in a printer I get a MAXTEMP or any other M999 error, as you say I need to restart the service and even reset the printer to get it back on. This is NOT the case. Extruder is simply ignoring me. And the weirdest part is "just" the THREE Extruder drivers, eveby bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
No, i disabled "Cold extrusion prevention" in Marlin, so Im covered there. And no, X motor won't spin either in the Ex connectors.by bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
There comes the day a printer stops extruding and after a brief research I notice the extruder motor is not spining. This is what I've found so far: - X, Y, Z axis move flawless. - Taking measurements on all the DRV potentiometers (green on the below image, X, Y, Z, E0, E1, E2 from right to left) and all of them get the same voltage. - It's NOT a faulty motor. I temp placed it on the X axis andby bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
Veamos si se explicarme: Llega el dia que la impresora deja de extruir, porque el motor, averiguo, deja de girar. Lo que he averiguado hasta el momento: - Los ejes X, Y y Z funcionan sin problemas. - He tomado mediciones en TODOS los potenciometros de los DRV (en verde X, Y, Z, E0, E1 y E2) y a todos les llega mas o menos la misma tension. - No es culpa del motor (si lo pongo en el eje X, el mby bolsoncerrado - RepRap en Español

Well it seems drivers are back "alive"?!?! For whatever reason either the motherboard was "overloaded" with whatever currents involved or octoprint was nuts (even if i rebooted several times). Im now running PID autotuning to see if I recover the extruder capabilities....by bolsoncerrado - General
ANy1 else? :'(by bolsoncerrado - General
Let's see if i can explain myself correctly enough: I have a printer with a RUMBA board and MARLIN 1.1RC7C in it that was working fine, until the other day that it was starting to perform weird heating issues. By rebooting octoprint and resetting the printer, even letting it cool down for a while, I managed to heat both extruder and bed fine. Then I tried to extrude filament but the motor didntby bolsoncerrado - General
OK i'll reword it... It may have killed each driver I have connected its wires onto. Question is HOW? And...HOW can I check if its the motor the faulty one or the wiring up to it that has a short or something? The voltage drop to 11V is not a fact, as I never checked the voltage on this printer before, probably came "underrated" from factory. Controller is fine. Once again, nothing seems friby bolsoncerrado - Stepper Motors, Servo Motors, DC Motors
