I have a Creality Cr-10 and, if I remember correctly, if you try printing with a nozzle temp over 250 C you can damage the PTFE filament guide tube. I've got three or four creality printers as well. They've been hit or miss for me. I have to level the bed on every print and sometimes they still have issues. The great thing about the F410 is it just works every time with zero fuss. Of course, I could buy 12 - 15 crealities for the price... Btw -- the Qidi X-Plus printer is really really great for the money.

Beachboy Posted September 8, 2020 Share Posted September 8, 2020 Why ecodrift used so much washers in their tutorial?I dont get it, are the bearing holes offset that much? Quote Link to comment Share on other sites More sharing options...

Some of the bearing pockets (C, D - see my pictures in this thread for reference) are countersunk by 1-2mm. I'll have my parts list and procedure finished this week and show you exactly what you need and where it goes.

Beachboy Posted September 8, 2020 Share Posted September 8, 2020 okay, but they said to put 4mm washer to the axel.. Check out one the bushing picture with washers all over it..(sorry cant upload pic) I will be waiting for your post for the procedure & list of parts needed..🙏🙏 Quote Link to comment Share on other sites More sharing options...

Check out one the bushing picture with washers all over it..(sorry cant upload pic) It looks like they're replacing some of their bearings with a stack of washers. If they're 19mm OD this is probably ok. I opted for the custom bushing route because I'm OCD and have a 3D printer that can printer fiber reinforced nylon.

Beachboy Posted September 8, 2020 Share Posted September 8, 2020 as stated, the washer size is 10x14 and if they did have 19mm OD for replacing some bearings, how strong are those washers anyway... I hope your 3D printed bushings can take a lot of beating especially when used in offroad tracks... Quote Link to comment Share on other sites More sharing options...

Feynman Posted September 9, 2020 Author Share Posted September 9, 2020 (edited) Just did a (failed) test run with gf reinforced nylon and can tell you this stuff is extremely robust. I have zero worries that these bushings will fail. Now to try to get them to stick to the print bed!

Beachboy Posted September 9, 2020 Share Posted September 9, 2020 F**k...🤬🤬🤬🤬... one of the bolt head in the middle the one with oversized washer got destroyed when I open it...those bolt quality sucks.. and the worst is I cannot find any replacement 😭😭😭😭😭😭 Quote Link to comment Share on other sites More sharing options...

Beachboy Posted September 9, 2020 Share Posted September 9, 2020 I havent measured the bushing lenght but is it really 25mm?Thought would be longer also, when I press the suspension down with no air, I noticed something rubbing the fender, any idea what make the sound?

null Posted September 9, 2020 Share Posted September 9, 2020 BTW consider torx heads if you replace screws, they take more torque than classic hex. Quote Link to comment Share on other sites More sharing options...

Popular Post Rehab1 Posted September 11, 2020 Popular Post Share Posted September 11, 2020 (edited) @Feynman your fantastic R&D on the S18 suspension made me break my vow to my wife. I swore that my wheel modification days were over. So what’s the current record for split washers? I just removed 2 from inside the arm and 1 on the outside bilaterally- total 6. I’m currently experimenting with thrust bearings but your creative 3D bushings would definitely be less expensive. Looking forward to seeing your finished design. I have another set of suspension arms arriving tomorrow courtesy of Jason. My mods will require additional machining so with spares I can go full tilt without worrying about destroying the entire set up.

The whole machining process would be easier if I can find the exact end mill bit with a 10mm pilot. I’m using a cross slide milling vise secured to a drill press so I expect to have a few chatters when the pockets are modified. 2 Quote Link to comment Share on other sites More sharing options...

eve Posted September 12, 2020 Share Posted September 12, 2020 @Feynman Does your setup use bushing only? I would like to keep the bearings. They move more freely then bushings. Quote Link to comment Share on other sites More sharing options...

They move more freely then bushings. Currently I'm using only bushings for the shaft rotation, but am trying some thrust bearings to keep the arms from binding with the sliders, body and each other. You could definitely use the bearings instead of bushings. I'll post pics and all parts I'm using once I land on a final design. I'm OCD and am on the 15th iteration or so of bushings. :-D 1 Quote Link to comment Share on other sites More sharing options...
