Very irregular first layer, "Life Z" file.

Red Planet — Wed, 20 May 2020 22:09:56 +0000

My prints adhere to the bed, and they turn out pretty well. But the first layer gives me problems. So I used Jeff's "Life Z" file and played with live Z adjustment to try to figure out what is going on. Weirdness ensued.

If you look at the attached photo, you'll see two Life Z prints, at different Z settings. The one on the left is what I thought should be about the right setting. The one on the right is at a higher setting, obviously too high.

What's striking is the consistency of the irregularities. The exact same pattern is printed both times, just at different Z heights.

There are areas that look about right, and then areas where the plastic piles up and gets ragged.

I've washed the bed with Dawn, rinsed and dried it, then wiped it down with IPA. I've surfaced it with a dry dishwashing sponge to remove material. Still the same result.

So I'm looking for some understanding of what's happening, and how to correct it.

Printbed keeps driving in to endstop

byron.l — Tue, 14 Apr 2020 17:24:08 +0000

Hi,

After some small maintenance (tightening the X axis belt) my printer started to drive into the endstop before printing.

Anyone knows how to fix this?

enormous Layer shift

bestellungen-1 — Fri, 20 Mar 2020 11:56:49 +0000

Hello, we had this layer shift with almost all of our 3 prusas.
Could maybe someone tell us what is happening and maybe how to deal with the problem.
The offset is about 3cm and about 70 percent of the print is done.

Greetings

MK2 to MK2S Upgrade list

3Der — Fri, 14 Feb 2020 16:47:24 +0000

I have a MK2 but would like to upgrade to MK2S. Does anyone have the parts list I would need. I would hate to come up short during the upgrade. I was wondering is there are any thing else additional like screws etc.

I currently have the following list:

-U-Bolts 1 set (contains 3)

-Smooth Rods (1 set of rods)

-Bearings LM8UU (10x)

Filament Seizes in Hotend

Ramsey McEllan — Mon, 11 Nov 2019 19:07:21 +0000

My extruder will print fine for the first few layers, but then the layers become thin and broken before the filament stops coming out. The hotend will stay hot and the extruder motor turns correctly, but the filament is visibly not moving through. I checked all of my electrical connectors and adjusted the bearing tension, but the problem persists. I have been having this problem since I changed my PLA spool from "Galaxy Black" to "Orange". See the included photos of the bit holder I have been trying to print. The bit holder has two halves that will be joined together when completed. The galaxy black spool printed the first object fine, but the orange spool seems to be having trouble with the other half. My theory is that because of the complexity of each layer, the extruder is retracting too quickly and too frequently, causing the gear to chew into the filament and preventing further movement. Any ideas? Has anyone had this problem?

Selftest error, Axis Length (X)

paul-werner — Sun, 20 Oct 2019 16:45:16 +0000

So everything is put together, no obstructions and I cannot get past the selftest calibration wizard. It is the X axis length error. I have triple checked everything, belt tension, ease of bearings, wiring, etc. Getting absolutely nowhere. Do I need to take it apart and start over?

Dead Prusa Mk2 while changing Nozzle.

Delslogos 3D Printing — Sun, 05 May 2019 09:27:10 +0000

Looking for help,

While changing the nozzle I heard a tick and then the power went out. I am guessing I must of contacted a wire on the heatblock which made the power go out. Has anyone else had this issue or know what I can do to get it back up and running?

When trying to turn on the power just nothing powers on. I am guessing the psu for starters?

Many thanks

Derek.

Printed MK2.5 Extruder parts for MK2S because stock parts are almost broken but then realizing that I need extra parts

RichHomieTee — Fri, 01 Mar 2019 06:02:44 +0000

Sorry for the long title but I have a very rare dilemma I'm dealing with here. My MK2S was very good at printing until a recent giant blob formed around the extruder, this is the 3rd time it has happened. I knew that if I didn't get new parts the plastic could drip down causing it to interfere with the probe. So I decided to print "New" parts for my printer and I saw an option to upgrade my parts from "MK2S" to "MK2.5". I thought this would benefit me since an upgrade means better parts and I thought "It's an upgrade specifically designed to turn the MK2S' extruder parts to Mk2.5 extruder parts. Which means that to upgrade it, all I have to do is print the parts and reassemble them!" Boi was a wrong :( , because today I just figured out that you need non 3D printed parts to do the upgrade. However I'm afraid that I can't reassemble it since it since the out-of-the-box parts are almost broken.

With my whole life story in mind I'm seeking answer to the following questions below.

- Where can I get the metal parts to complete the upgrade that are not listed in the store?
- Should I use the MK2.5 parts or stick with the OG parts?

P.S. The whole point of this project was to repair and make "Better Parts" for my MK2S.

P.S.S. If you need any pictures or videos let me know , I had to make this topic quickly.
