this super great .. you could put a bed of 20 x 30. 20 for X axis, 30 for Y axis

Hi! First of all I have to say good job! :) Do you have scheme/location of drilled holes on frame? Thank you

Since the dimensions of the printer changed a bit, does anyone has the configuration file for marlin I can use?

Too many variable, is not advisable to do that. Search for a flat AM8 marlin configuration file

I am finishing your welded am8hd. But,pls,could you tell me what are "pin" and "z ring" files? Thanks in advance.

pin.stl is a file finished there buy mistake, not part of the project. Z ring is part of the Z right or Z left support with bearing adaptor, the ring is just to replace the bearings in case you printed the support for the bearings but you don't have the bearings.

Thanks for your reply. Very clear.

Thanks for your design! My anet A8 transformed to your Am8hd design are making great prints! :)

If some one needs a spool holder for this design, I have made a adjustments of the original Prusa i3 Mk3 to fit on the Am8hd.


Note: frenodog, feel free to add this stl file to your design if you wish so.

Thanks :)

Hi, can you re-upload .rar as .zip because its not readable/damaged on both mac and win. Thanks

Hi, great project. I want to know what is the recommended thickness for the metal bars.

Thanks in advance.

I did them in 2 and 1.5 mm both are very fine. 2mm is heavier and in my opinion not necessary. 1.5 was fine but need to be more carefully when welding so that you don't make a hole.

Ok, thanks. Here I have 0.9,mm 1.2mm, 1.6mm and 2mm options
Do you think 1.6mm would be fine?

This is SO awesome! I would like to build it very much and if you can not send one to me I need to try myself :) Love it that you don't use the generic 2020/3030 aluminium instead heavy steel. Massive! I think the best upgrade ever for the Anet A8.... Cheers!

Gracias me pongo a construirlo.

Nice and hard design. I try to build it, but what is the place to situate the vertical sides?

hi frenodog,

Very nice design! Thanks for that.
I build the machine now. Could you tell me the type of bearing ?
Thank You.

normal 608z or 608zz or any abec rating bearing you find in skateboard, rollerblade, fidget spinner. They're very common, if you have somethig tolling on bearing at 90% it's one of those.

I started this print, so see how it goes! I like the design as the rectangular tube is inexpensive and for the light gauge you can fit this up with a buzzbox no problem. Nice design!
