Re: Printer Response - 6 Jahre zuvor
Could this be that the setting of your serial connection is wrong, so that the Pi interprets the parity bit of the arriving byte to be the 8th data bit? (That could explain why the "k" is received correctly and the "o" not - the 2 characters have different parity.)von enif - Firmware - Marlin
Re: Marlin 1.1.8 - MKS Gen 1.4 and TMC 2100 - 6 Jahre zuvor
After having changed the steps/mm in the firmware, have reset the values to the (new) defaults and stored them into EEPROM? This can be done via display menu or by sending manually the gcodes M502 followed by M500. As for the micro stepping changes not having any effect, note that there are some RAMPS boards around which have the jumper pins shorted on the PCB, so that the jumper settings havevon enif - Firmware - Marlin
Re: Stepper replacement with TMC2208 - 6 Jahre zuvor
Have you checked that the wiring of the cable is the same on both types of steppers? Wrong wiring will cause the kind of problem you experience. Check the wire pairs which correspond to each coil - if you short them, and turn the motor by hand, you will that it needs more force. If the coils are not on the same wire pairs, you will need to change the cable.von enif - Controllers

Re: Issue with Marlin and reprap display - 6 Jahre zuvor
Did you see that the documentation says that this OLED is for "3.3Volts only"? Do you have a printer controller board which generates 3.3V signals? Or have you found in the documentation something saying that the signal inputs are 5V tolerant?von enif - Firmware - Marlin

Re: Stepper motor locks up when going higher than 8mm/s - 6 Jahre zuvor
Hermanelfino, have you checked the Wiki page about maximum step rates? IMHO you are simply trying to operate the M8 Y-axis at a step rate which is way to high for the Marlin/Mega setup you have. With 2048 steps/mm you will reach the safe limit of 10000steps/sec at about 5mm/sec - so I wouldn't even trust the 8mm/sec you are using. This has nothing to do with the stepper motors you use, it's thevon enif - Stepper Motors, Servo Motors, DC Motors
Re: Stepper motor locks up when going higher than 8mm/s - 6 Jahre zuvor
Please explain us the mechanical setup of your axis. What belts/pulleys resp threaded rods are you using on which axes? How is your setting of STEPS/mm for the axes in Marlin's Configuration.h?von enif - Stepper Motors, Servo Motors, DC Motors
Re: Stepper motor locks up when going higher than 8mm/s - 6 Jahre zuvor
From your video it looks as if your printer does not use pulleys and belts, but uses standard threaded rods (M8?) for the X/Y linear movements... If so, have you calculated the actual step rates Marlin must generate to reach your desired speed and compared this with the limits of your controller setup? According to the table on the step rates page of the RapRap Wiki, using an M8 thread with Marvon enif - Stepper Motors, Servo Motors, DC Motors

Könnte es evtl. Überextrusion sein?von enif - Software
Re: Extruder direction voltage question - 6 Jahre zuvor
Maybe you could solve the problem by enabling your extruder stepper externally with a constant signal and then use an external gate to combine the E_ENABLE and E0_DIR signals generated by Marlin for activating your relay. To do this, you would need to set DISABLE_E to true in your Configuration.h, so that the generated E_ENABLE signal shows the active/idling state of the extruder.von enif - Firmware - Marlin

Re: Anycubic i3 Mega mit Hotendproblem! - 6 Jahre zuvor
Was passiert denn, wenn du eine niedrigere Temperatur, z.B. 50 (40,30,...) Grad einstellst? Pendelt sich der Drucker dann auf eine niedrigere Temperatur ein? Oder heizt er trotzdem endlos weiter bis es anfängt zu rauchen?von enif - Extruder, Hotends & verschiedene Materialien
Re: Anycubic i3 Mega mit Hotendproblem! - 6 Jahre zuvor
Hast du mit den neuen Hotends den alten Thermistor verwendet? Wenn ja, hat er guten Kontakt (Wärmeleitpaste?) zum Hotend? Wenn nein, bist du sicher, dass der Thermistor vom genau gleichen Typ ist? Wenn nicht, dann musst den Thermistor in der Firmware neu konfigurieren.von enif - Extruder, Hotends & verschiedene Materialien
Re: Ajouter item dans le menu LCD - 6 Jahre zuvor
Biensur on peut reprogrammer X_PROBE_OFFSET_FROM_EXTRUDER comme une variable. Mais il faudrait alors aussi reprogrammer tous les autres macros qui derivent de X_PROBE_OFFSET_FROM_EXTRUDER - et il y en a plein... Donc je ne dis pas que ce n'est pas possible, mais que ce n'est probablement pas simple et qu'il y a des problemes bien plus difficiles a resoudre que juste d'ajouter un item dans le menuvon enif - RepRap Groupe d'Utilisateurs Francophone
Re: Ajouter item dans le menu LCD - 6 Jahre zuvor
Desole, mais je doute que ce que tu veux faire soit aussi simple que tu penses... X_PROBE_OFFSET_FROM_EXTRUDER n'est pas une variable qu'on peux changer lors de l'execution de Marlin, mais plutot un macro au niveau du programme qui est compile directement dans le code. Donc meme si tu sais comment ajouter un item dans le menu LCD, ca ne te permettrait pas de modifier la valeur de X_PROBE_OFFSvon enif - RepRap Groupe d'Utilisateurs Francophone

Re: Heated Bed aluminium 31x31 FLSun Cube draining power - 6 Jahre zuvor
Assuming that your 35oz actually means 35um (which is 1oz/ft2) the circuitcalculator.com gives indeed about 0.5 Ohm at 100C. At 20C however the resistance is 0.39 Ohm, which at 12V comes to an wattage of 12V*12V/0.39Ohm = 369W - which i quite near the value 388W that you measured with your power meter.von enif - Controllers
