Snapmaker 2.0 CNC Brace Mod
HTML-код
- Опубликовано: 12 сен 2024
- This roller brace design is something I have been working on for the last year as the Snapmaker 2.0 (SM) has a good deal of slop in its linear modules. Some may say "you just need to open up and tighten the internal rollers in your linear modules" but believe me when I say that is not the issue... It is a pretty well known fact in the SM community forums that these machines have a number of shortcomings especially when it comes to the rigidity and constraints of motion in its linear modules while using the CNC functionality. Therefore I have created this mod which is very easy and cheap for anyone to implement! The goal of this specific mod is to remove the rotational slop of the X-Axis by bracing it at the connection points to both Z-Axis linear rails. This effectively reduces the "splaying out" of the tool when making CNC cuts which improves the tolerance of the end product and prolongs tool life.

Awesome!
Im planning to buy one of these beast to mill aluminum, your upgrade are a major improvement in the way to increase rigidity of the frame.
Will do that for sure 😎
I think you could make simalar braces for the tool head, not only to ride the dust covers, but also the top and bottom of the linear module. Essentially bracing all 4 sides of the tool head to the linear module.
I'd really love to be able to cnc aluminum, and other than the toolhead itself, I understand the stiffness of the machine is the limiting factor.
Following, thank you!
Already made a brace for the tool head you can check out on my Thingiverse, I just haven't edited the video as of yet
@@E-Tech-LabsHow about a "fan" or 3d printed fan blades that slide over the spindle to help mitigate any removed material from the work area.
Numbers look good, would be nice to see some real life scenario differences with cnc for example tho.
Dude this is awesome - just ordered my A250 yesterday and I’m planning to print these ASAP. Do you think PETG would be able to handle the strains?
PETG could work for CNC but the machine tends to get pretty hot while 3D printing so they might warp, if its not in an enclosure it would probably be fine but there's only one way to find out! (*Note: ASA is really easy to print for a high temp thermoplastic unlike ABS)
@@E-Tech-Labs good to know. I have spent the past year working with polypro and really just don’t want to get into it with ABS. I’ll be using the snap maker mostly for CNC tho so I’ll try PETG and get back to you.
Thank you for this video and all the steps of description. CAn yu tell us which machine you have ? Original, 2.0 ? I have the 2.0 A350T and I do not see so much deflection without stiffening mods.
I also have a snapmaker 2.0 A350T, however mine is one of the original versions with the loud linear rails so if you have a newer one or replaced the rails it might not be as big of a problem. I also have almost a thousand hours of print time on mine so part of it could be due to wear or looseness of the internal guide wheels.
Merci, thank you for this advice. Good luck for your Chanel. I wait for next video from you. Sorry for my english, it is so so.
nice video
While the basic idea is sound, the design, assembly and methodology used, will destroy linear rails! Why? This design, doesn’t allow for fine adjustment, and actually uses paper shims under the front edge of the wheel brackets. This is wedging the wheel against the Z linear rails to remove play (rocking) on the X rail. This method is loading against the internal feed screws, adding torque to the rail assembly. Those “wheels” need to have an eccentric adjustment (as found on Ender 3 printers). Another problem with this method is that it doesn’t keep the module perpendicular to the bed. If the laser, or spindle is not true to the bed, they will cut at an angle. The design should allow fine tuning, which it doesn’t currently do. This is forcing rigidity, not just providing stability.
Have you worked with the quick swap kit?
Does that improve the toolhead play?
👏🏼👏🏼👏🏼👍😁
Sorry but this cant work!...
Natürlich, es kann funktionieren.
