Printing issues ...
For reference: I was using an older version of the Marlin firmware that was buggy. The fix was to grab the latest release branch.

Hi folks,
No matter what value I set my autoleveling z offset in my firmware, the hot end remains 200 microns too high. My measured offset started at -5.2, and I dropped it to -5.1, -5.0, -4.9, it seems to make no difference.
I change the number in the firmware, upload, then do a G28 X0 Y0, then a G29, then try and print.
No luck.

This issue only recently started occurring, so I know it's not an issue with the filament. I think it's a mechanical issue, but not sure of what type.
I tried lowering the print speed, but no luck yet. I'll try lowering it a bit more.
Here's another picture of the issue. Note the bumps and divots, circled in red, but also note the edges are fine, circled in green:
Thanks!!

Ah gotcha. It seemed to be a design flaw. Now my curiosity is piqued though. Does anyone print and use that x carriage? I've never seen a pic of anyone using it. When people use it, have they been concerned about the missing walls?
Thanks!

60 mm/s for all perimeters. I've noticed a bit of "ringing" near the bumps as well, if that makes sense,.

Hi folks,
I'm fairly happy with my prints so far, but recently my prints started to develop slight bends or divots on the corners or sides. Here is a pic:
Notice how the teeth are slightly bent, the hex holes are misshapen, and the sides have slight lumps to them. This is a more extreme case of this issue.
Both belts feel fairly tight. There is no play anywhere I can tell.
Uncertain what el

Sounds good! I never knew about this issue.
Do high quality RAMPS boards not have this issue, or is it a design flaw that should be addressed in RAMPS 1.5? Perhaps I should file a bug report.
Cheers!

Nope! No 5V regulator, just pins off the board going straight to the servo. Ah, so you are suggesting using a whole other 5V supply, just for the supply pin on the servo. Interesting idea. I would probably use a wall wart going into a 7805. Does that sound like a sane idea?
Thanks!

Hi folks,
I'm trying to control a 9g servo with my ramps board. It works great until the printer is printing something, then the servo will meander aimlessly the entire time. Obviously I can't have my servo wandering like this.
Could my ramps board be bad? Is there any sort of stabilizing circuitry I can add to my servo so this doesn't happen? Maybe a cap?
Any other ideas?
Thanks!

Hi folks,
It looks like the x-carriage has a design problem. Taken from here:
Please see the rendering in openscad here:
Note that the edge of the nut slot on the top side of the picture is very thin, it appears to be maybe 50 microns at the most.
Any thoughts on why this is happening? Do other people have this issue?
Thanks!

Hmm...with extrusion width set to 0.35 mm I'm having a problem with delamination. I had extrusion width set to default before I tried 0.5mm, and I was having those same delamination issues.

Looks like there are a few improvements with the "official" over "vanilla". Has anyone used both of these? What has been your experience?
Thanks!

This is exactly what I was looking for! Thank you so much!
My x ends look a bit different than yours but I'll see if I can adapt your STLs to fit!
Thanks again!

Ahh, so perhaps that is the cause of the infill gap issue?

Ah gotcha. Prusa i3, .4 mm nozzle size. I was told to use 0.5 mm extrusion width.

Hi folks,
I'm having this issue:
However, that page doesn't mention which settings to try adjusting, and it doesn't say which way to go with those settings.
My extrusion width is 0.55, my infill/perimeter overlap is 50%, but I'm still seeing the issue. I tried changing my extrusion width from 0.5 to 0.55, and as a separate test, turned up the overlap from 35% to 50%.
Can you recommend other

Ahh I see! You adjust the position of the frame along the y axis!

Hi folks,
I have noticed that the forward linear bearings on the y carriage end up running into the y axis corners about 20 mm before the extruder reaches the end of the y axis.
How do you get the full 200 mm out of the y axis? Do you need a special y carriage?
Thanks!

Ahhh ok thank you! What's the difference between vanilla and what I thought was the official repo?

Hi folks,
I'm trying to print a replacement x carriage. I downloaded and built the i3 sources, but it looks like there are a few issues with the x carriage.
Here is the result:
This is the part I was expecting:
(except the holes should be rounded, not hex)
My issues are:
1. The asymmetry is somewhat maddening. Is there a functional reason for it?
2. The holes are supposed to be round, not h

Hi folks,
I have some variant of the Greg's extruder, (I think it's the Greg's accessible extruder), and I need a cable chain since my extruder wiring bundle is getting caught on the bed. o_O
I can find plenty of cable chains on thingiverse, but how does the chain attach to the extruder? I found this:
but it's for a completely different extruder. There's gotta be some folks out there using a

Hi folks,
For those of you that use an enclosure, do you put the arduino and ramps board inside or outside the enclosure?
If it's outside, what sort of interface(s) do you use to bring wires from the inside to the outside? Do you run the wires under the box? If so, where does your ramps board live relative to the rest of the printer? I can't seem to find a spot that works. My original spot was

Thank you so much for the help. I'm not about to give up just yet, I was a bit pissed off a few hours ago.
My extruder is an e3dv6 with a 0.4mm nozzle. I have been doing 0.3mm for the first layer, and 0.2mm for all other layers. Maybe I should be doing 0.3 mm for all layers? Or stick with 0.2mm?
Do you think I should go with higher or lower extrusion temps? I feel like too high might cause it t

Hi folks,
I'm getting major delamination issues:
The picture shown did lift off the bed a bit, but I have had prints that didn't lift at all and still delaminated.
I have tried turning the hotend temp up to 240, 250, 260, and even 270, with no luck.
I have also tried enclosing the printer in a cardboard box. Lid open, lid closed, and lid open with a heat lamp.
ABS type is chi mei 747.

My brims definitely stick, but the skirt itself doesn't stick. I have tried skirts of 3-5 mm, but any larger than that seems like a waste of filament.
If the skirt was attached to the brim, it would definitely stick.
Thanks!

Thank you! The fix was to set the extrusion width to 0.5 mm in slic3r.

Hi folks.
I'm trying to print a full height skirt to prevent delamination, as described here:
However, after about 10 mm of height, the skirt pops off the heated plate. Attaching it to the brim would work perfectly. I have tried setting skirt distance to 0mm, but it isn't attached to the brim, it's about 1mm away. I have tried various brim widths, 5mm, 10mm, etc.
Any thoughts?
