Hi! I have found this website about E3D hotend troubleshooting. I made the following changes: - Disassembled the hotend, and cleared as much as possibe. I burned the nozzle in butane torch to get rid of anything what maybe clogged it. The remaining PLA inside is turned into ash. - Flattened the back end of the nozzle and the front end of the heat break tube on fine grinding stone. (Where they toby DeXTeR323i - Mechanics
I tought it is relyable, because I had seen that sold in many printer kits... Okay, thank you for your answer! Does anyone else have experiences with this E3D hotend clone? Does it work relyable? Maybe I should order another one. Maybe only this is faulty.by DeXTeR323i - Mechanics
I changed configuration to bowden solution, because I had large mass on the moving "carriage" with the extruder motor mounted on it. I wanted to loose weight on fast moving printing carriage, so I decided to remove the extrduer motor and mount it on the printer's frame. Because of that, I needed a new hotend with bowden mounting on it, and this all metal E3D clone seemed modular, solid, and relyaby DeXTeR323i - Mechanics
Hello Reprappers! I have a Prusa i3 clone, and I decided to convert into a bowden extruder configuration. I have bought an E3D hotend like this. My problem is the following: I heat up the hotend to 200C, I extrude 10mm filament with normal speed, and it goes ok. But If I try to extrude another 10mm of filament immediately, then the extruder motor starts to skip/jump some steps. The pressure raisby DeXTeR323i - Mechanics
Hi reprappers! I have a Prusa i3 with a Melzi board. I have just customized my printer: I replaced the right Z motor with a threaded rod, and connected it to the remaining left Z motor with a timing belt. I have the following problem with it: All my other motors (X, Y, and E) are locked after they were moved by the controller (I cannot rotate them by hand), but not the Z motor. I tought the causby DeXTeR323i - Prusa i3 and variants
Hi elwood127! Thank you for this post! I have bought an Aliexpress Acrylic Prusa I3 more than a year ago, and I always had problem with it, especially with Z motors. I always faced with misaligned X "bridge" during the print job. I had to continuosly check the two heights with caliper and fine tune it during print! I also used a belt to connect the two threaded rods, but I kept the two Z motors,by DeXTeR323i - Reprappers
Okay, it seems I have found the solution... I tried to fine-tune the potentiometer, and now the strength of the motors seems ok. I can not stop them by hand. At this time I became suspicious: What if I have no big problem with the power of motors, but the speed of Z motors instead? Can I set the Z speed to low? I checked all the slicer settings, but did not find specific Z axis speed. I did a teby DeXTeR323i - Controllers
Thank you, I will try this finger temp "measure" tomorrow. - I have tried to swap outputs before... With one motor connected, it seems ok, but with two motors, the result is the same. - I have no firmware to configure. I got a kit to assemble, connect it to repetier-host, and use. (I am playing with arduinos also, I have arduino ide, so I think I have the possibility to upload firmware, but I havby DeXTeR323i - Controllers
Hi! Thank you for the answer! Yes, I have heard this series-connecting tip before. I tried it, the motors feels stronger, but yet not strong enough. (currently they are in series) Maybe the printer parts don't fit perfectly, and there is some "stress" in the machine? Sadly, there is not any sign or part number on motors. Manufacturer said, these are Nema 17 motors. That is all I know. I have anby DeXTeR323i - Controllers
Hi guys! I have bought this 3D printer from Aliexpress about a year ago, and from that time, I have problems with Z axis motors. I hope, finally You can help me! I don't know what type of controller it has, or what the name of this printer... It has two separate Z axis motors, and those are connected to the same output. From the first time, I had problems with the two motors were not raising thby DeXTeR323i - Controllers
