Solved: Y-Axis not gliding smoothly

by PimN

Edit: I managed to solve my problem by slightly loosening the bearing housings from the heated bed frame. The bed is now sliding smoother. Thank you everyone.

I've had the A8 for about 5 days now, but after a couple of days the stock linear bearings on the y-axis rods (the ones holding the heated bed), made this horrible grinding noise whenever the the bed was moved along the y-axis. I decided to purchase Igus Drylin LM8UU Polymer bearings (http://www.ebay.com/itm/3D-Printer-Solid-Polymer-LM8UU-Bearing-8mm-shaft-Igus-Drylin-RJ4JP-01-08-/201571607189?var=&hash=item2eee9aa295:m:mHflNMVxgB3DEgcF_dKWemg) to replace the stock bearings. Everything worked out I guess, but now when I'm printing, the y-axis motor has a very hard time moving the heated bed. The movements are choppy, which messes up the prints. The y-axis motor also gets very hot, way hotter than the the x-axis motor for example. I think that's also maybe because there's something wrong with the bearings.

It would be weird however since the Igus bearings glided really smoothly when I had the guiding rods seperate from the printer. Now that they are installed in the printer, it takes alot of force to move the bed. Maybe the rods aren't aligned or something? I don't know if that's an issue that can even happen with the Anet A8. Anyways, any ideas or suggestions are welcome!

Anet A8 Auto Leveling Sensor: TRONYX XY-08N

by carloscastro

Hi All,

When I bought my Anet, I also bought this sensor http://www.gearbest.com/3d-printer-parts/pp_591321.html?wid=21, as it seemed equal to the ROKO SN04-N (https://3dprint.wiki/reprap/anet/a8/improvement/autobedleveling). However, now that it came I don't find any information about it, so can someone tell me if it's usable on A8?

Best Regards,
Carlos

Micro SD Extension Cable

by Massalum

Hi, guys. Using Anet A8, about 5 years old. I'm looking at installing an extension cable from the micro sd slot on the motherboard to an easier access point. Ordered one from Amazon (made by LANMU) and, unfortunately, the male end would not "latch" into the slot on the mainboard. Reading the reviews it appears that this is a common problem with this product - which is now being returned to Amazon.

Wondering if there is an extension cable out there, currently available, that will actually lock into the micro SD slot. Or is there a way to modify the male end of the LANMU cable to make it lock in (looks like it needs to be thicker?)?

Appreciate any info.

Anet A8 Controller Board

by Guitarman1

Hi there guys. I have an Anet A8 that I have used for a few years and my Mainboard has now decided it's time to go. I was looking at the BigTreetech SKR 1,4 board. Can anyone help me on what dirvers would be the best to use. The following is readily available:
TMC 2100
TMC 2130
A 4988 or the
DRV8825
I am not sure which of the drivers would be the best to use.

Thanks in advance for your help.

Kind regards

Can anyone tell me what I have and help me out?

by hdstonemeister

Ok, so I got what I was told was an Anet A8 from a website. It was taken apart and shipped to me. Not sure if what I have is really an Anet A8. I have gotten it together this far, but I am in need of a bit of help to finish it up.

There are 2 pictures of the progress so far, then the rest are parts that I just simply cannot figure out where they go or where to place them on the part I have already assembled. I can figure out what stepper motor goes to what part of the motherboard. I just can't figure out where the motherboard is supposed to be installed. I cannot figure out where the display is supposed to be mounted either. As for the rest of the pieces, I can't make heads or tails what to do with them either.

Any help, possible pictures or maybe files to print out on one of my other printers so as to provide something for the extra parts to fit on would be great!

Again, thank you for any help that you can provide!
