Process to update Anet motherboard to Marlin firmware?

by DarkTerritory

K so I'm thinking abut trying to upgrade my old Anet A8 motherboard to Marlin. I have been looking around on the intertubes and now I'm more confused than ever. Everyone uses a different flavor of Marlin and no one does the update in the same way. Many also seem to leave out important steps.

Can someone help me or direct me to an upgrade posting or video on how to do this? Assume I know nothing (because I don't).

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,

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 won't boot with BLTouch connected.

by Itsfun

I've had my Anet A8 going with a BLtouch clone for a couple of years through marlin firmware.
Changed to klipper the other day and noticed that klipper didn't play well with the clone sensor, so i bought a genuine bltouch 3.1.
When i changed to the new sensor the printer won't boot properly.
If i disconnect the servo leads i can get the printer to boot, and once that is done i can connect the leads and get the sensor working as it should.

I have a couple of working theories right now:
Either i should set the output mode of the sensor to 5v, however i don't know if that's correct for the sensor pin on the motherboard.
Else the sensor draws too much current at boot so the board can't handle it.

As of right now i believe i have the sensor pin wired into the lcd same as the clone probe did.
I've seen some guys have disconnected the wire going to the lcd, but i can't find out why and if it has any drawbacks with this method.

Anyone else had this problem?
