Welcome to the SeeMeCNC Community

I made an oops on my max and melted the tube inside the hotend.

I tried printing without it and that just made a bigger mess.

Anyway, assuming I can somehow get the plastic out of the PEEK insulator, does anybody have what length the PTFE tube should be? (Didn't see it in the plans anywhere.)

Hey all, In the last few days I got an envelope arrived from SeeMeCNC. Inside, it contained a new nozzle. No note. No nothing. So I'm like, "wha-wha??". I presume they want me to use this in place of the original... but was there a problem or recall or something? (I'm hoping/wondering if this solves ...

2) This confuses me. I tried changing that, but now the height is wrong.

P.S. Item 3 seems to be fixed in the latest slic3r.

I found a the block you mentioned and some excellent calibration instructions here on thingiverse . I've tweaked it from complete garbage to fairly nice, so I'm very pleased, but I have a some new questions concerning my settings. 1) I've been getting great improvement setting the filament diameter ...

After some digging around, the best I found for retract calibration was this: http://richrap.blogspot.com/2012/01/slic3r-is-nicer-part-1-settings-and.html And that helped a lot. It got me back the same error-less cal cube only with maybe 40% less stringies. Now I feel like I have something to work ...

I did as directed and overall it did a lot better! :D Items 2 and 4 are still an issue, but most of the rest were pretty well solved. Of course, without any retraction the space in between the towers is a ghastly mess. Is there any tutorial or something that describes how to get this feature set up ...

Hurray, happy day, I finally got the calibration cube to print! Okay, it failed of course, but I'm still excited to at least see something 3D! My issue is that I don't have the experience yet to know what problem causes what symptom in the print. That's what I'm hoping you guys can help with ...

Just by accident I found what's going wrong! For some reason that I can't explain the first time you tell it to extrude it wants to move the carriage all the way to the top. After that you can issue the command with the carriage anywhere. Weird but whatev. :roll: Anyway, the hum I was hearing just ...

Here's another clue: I was wondering if I just had a bum motor control circuit on my rambo so I switched the plug to E1 and and swapped the values for the extruders at the very bottom of pins.h #define E0_STEP_PIN 33// 34 #define E0_DIR_PIN 42// 43 #define E0_ENABLE_PIN 25// 26 #define E0_MS1_PIN 63 ...

Thanks for the link. Seeing your build would have come in REALLY handy when I was building mine! If I have any friends that build one I'll be sure to direct them there. 8-) But in that thread you mention #define MICRO_STEPS 16 I don't have that. That's why I doubled the values in the line #define ...

Okay rambo is rev1.1b and there's a sticker also with part number (?) 10000829.

I removed it just to check things out and nothing looks different on e0 from any of the other motor circuits.

Thanks for your responses! I'm at work so I don't have the rambo version on me right now, but the code is this one: https://github.com/johnoly99/Marlin-for-rostockmax-rambo Hopefully that's right. Doing a diff against the checkout, here are all of my changes (all in Configuration.h) Synopsis: I ...

I'm excited to finally be about ready to start printing! Trouble is when I try to load fillimet the stepper just hums and no motion. :( I tried swapping e0 with x. When I g28 I get y+z and plastic feeding fine. Then I try clicking manual feed and x stepper just hums. So it has to be some setting or ...
