ORDER #2140 Request for spare parts following damage during first use
Hello,
My name is Edoardo and I am writing from Italy.
Unfortunately, after using the machine for the first time, some of the plastic components broke. I carefully followed all the instructions provided for the assembly. However, during the first use, after homing/resetting the machine, I tried to move it using the arrow controls without entering a source code, and several plastic components broke.
In my opinion, there may be an issue with the lack of a safety system capable of preventing an overload and, consequently, preventing damage to the components.
I would therefore like to know how I can obtain the necessary spare parts and whether they can be provided under warranty, considering that the problem occurred during the very first use of the machine.
I have attached photos of the damaged components, along with a list of the spare parts I need.
I look forward to your reply and to receiving instructions on how to proceed.
This is the list of spare parts that I need
Belt Guard — 3 pieces
Property: Polycarbonate
Inner Post — 6 pieces
Property: Glass fiber reinforced polycarbonate
many of the plastic parts on my machine have also broken.
All the inner posts, as well as one of the clamps and the clamping wedges, were unusable after a short period of machine usage.
I 3D-printed new clamping wedges, they were the first ones to fall apart, even before the first run of the machine.
Material: PETG… they seem to do their job much better and have been holding up under the load for several weeks now.
Last week I had to disassemble the machine due to two missing screws in one of the belt housings…my fault! This led to an improper working belt.
Whilst disassembly I found out about the broken inner posts and also a crack in the lower clamp, all of them nearby the joints of different parts.
Today I reassembled the machine after also 3D-printing the inner posts out of PETG.
They look pretty good to me—let’s see how things look after the first run over the next two hours.
My resumé:
In my opinion, the plastic parts aren’t designed to handle the forces acting on them. I think the 1 mm or less thickness in areas where screws are installed should be reconsidered. A quarter-turn too much, and the plastic is weakened, a following crack is only a matter of time.
But: I still ove this machine a lot!
So, if you own a 3D printer or know someone who does…go for it!
Last week I also had to disassemble my Maslow and all 4 posts broke in various places, and both of the clamping wedges broke.
As Roland mentioned, if you have a 3D printer, or a friend with a 3D printer, print replacement parts in PETG. The community has the files in various forum posts or in the Not Shop.
I really like the clamping wedge re-design which uses heat inserts. Nice for the thread to be embedded in the part.
I do not know if the original material is too thin, or too brittle, or a bit of both.
I feel if you did get new parts with the original materials, you may find they do not hold up as long as the 3D printed replacements.
the clamp wedges I re-designed with the melted threads still need a little tweaking.
Due to not really controllable shrinking of PETG the threads are a bit too far at the outer edges in my case.
I just returned from a test-run…no good news for now.
Probably also because of shrinking PETG after the print of the lower clamp, the Z-axis posts and the ones on the motors seem to tight.
Z-axis movement is more a stuttering with a lot of lost steps than a smooth movement.
My next step is to fix the original clamp somehow and give it another try.
Thanks a lot. Could you send me the files you designed? I have a friend who knows what he’s doing and has a printer, but I don’t know how to create the designs myself.
