Z Axis Homing Head Crash - 10 years ago
Attached is the Configuration.h I have a RepRap Prusa Mendel i3, and every time I home the Z axis again after I calibrate it, the head will crash into the bed. The Z Steps/mm setting of 4000 has worked before, but now it suddenly doesn't?by hhbhagat - Printing
Re: Part stretched vertically - 10 years ago
I measured my rods and they are less than 8mm in diameter, like 7.8mm. Is that bad? I got this 3D printer preassembled so that's my source of confusion here. My current value for my Z Steps is 4000.by hhbhagat - Printing
Part stretched vertically - 10 years ago
The part I am printing is 9.95mm in height, and the print turned out perfectly (except for one instance of acceleration issues and filament missing the mark). The actual printed height is 15.58mm. This is 156% higher than original. All the other dimensions are the same. Could it be something with my steps/mm? Thanks I am on a RepRap Prusa Mendel i3 w/ .4mm hotend Files: GCODE: STL: Slic3r Confiby hhbhagat - Printing
Re: Hobbed bolt shaving the filament - 12 years ago
It's not that I have gotten to the stage of printing even. I am trying for the hobbed bolt to not shave it.by hhbhagat - Printing
Re: Hobbed bolt shaving the filament - 12 years ago
I have been wavering between 640 steps/mm and 685 steps/mm and I have no idea what effect it has. My steppers are 1.8deg motors.by hhbhagat - Printing
Re: Hobbed bolt shaving the filament - 12 years ago
What I meant by the hotend working fine is that when I bypass the hobbed bolt, pushing it through is easygoing and without stutter or effort. What I want to know is whether I need a new hobbed bolt or if my firmware config is bunk. This printer is fairly new, about a month old.by hhbhagat - Printing
Re: Hobbed bolt shaving the filament - 12 years ago
So should I take off the hotend and clean it out or ream it? I cringe at the thought because I had bought this prebuilt. Is it too hard for a novice?by hhbhagat - Printing
Hobbed bolt shaving the filament - 12 years ago
The hotend itself is fine. But after a couple turns of the hobbed bolt, it starts to shave the filament and I keep having to clean it off because it cant grab it. Any suggestions? Picture: Thanks.by hhbhagat - Printing
Re: hobbed bolt jumping - 12 years ago
I don't know if I looked hard enough online, but I have no idea which pot is which. Labeled T1-4. The wires are of course wrapped so it it hard to even use a multimeter to test.by hhbhagat - Printing
Re: hobbed bolt jumping - 12 years ago
There it is. And they gave no instruction on the firmware tweaking, but gave info on how to calibrate the axes, print from sd, and maintenance and cleaning of bolts and the nozzle.by hhbhagat - Printing
Re: hobbed bolt jumping - 12 years ago
By all that, you mean that I need to configure the stepper motors in the firmware correct?by hhbhagat - Printing
Re: hobbed bolt jumping - 12 years ago
I am not able to get the exact model of the hotend because it was part of a preassembled Massdrop. But here is the webpage: The hotend is PLA and ABS compatible. Ubis .4mm nozzle with 1.75mm plastic. I have not adjusted any of the pots on the board. My prints also do not seem as smooth as they should be. They print just fine and complete, but there are little inconsistencies on the perimeter.by hhbhagat - Printing
hobbed bolt jumping - 12 years ago
Reprap prusa i2 I am having this weird noise where the hobbed bolt is jumping. Like this: The sharpie makes it clear. Is it something with my extruder temp? 190C. Or my esteps (I never configured them)by hhbhagat - Printing
Heated Bed Separation - 12 years ago
My heated bed started separating (maybe due to overtightening of the 4 screws I have). My model is the Prusa i2. There is maybe about 1 millimeter of lift on the middles of the print bed in the middle of each side. For right now, I can only print on the lower coordinates (x:0-60mm)(y:0-60mm) without having adhesion issues due to the hotend ramming into the previous layer on one corner. Is there aby hhbhagat - Printing
Re: Bent Z Rod a problem? - 12 years ago
No. the prints look perfect. I cant post a picture right now, but they are sturdy and have a good consistency of line. I am using Pronterface, but I have no idea whether or not my z-offset is working. I have tried applying painters tape, but the hotend simply rips through it on the first layer. Any idea how to do that? I have tried hairspray, but it may not be the right kind.by hhbhagat - Printing
Bent Z Rod a problem? - 12 years ago
I just got a pre-assambled RepRap Prusa i2 (Mendel), and one of my Z-axis rods are slightly bent. Video: Is it worth it to try to straighten it out before I print more, or can I simply leave it? The PLA prints that I am doing are consistently being knocked off by the hotend midway through printing. I tried a hotbed temp of 50 and 60C . The hotbed is uncoated/untaped glass. Do you think it is anby hhbhagat - Printing
