I went to the workshop this morning after letting the machine run last night. Everything that was on the rack was on the floor and the printer had 1 got off the edge of the table.
This thing has such violent moves that the vibrations almost had it fall on the floor.
The fast speed is great, but other than slowing it down, what else could I do to keep it from moving?
I realize now that as speed increases, bed slingers are not going to be a good choice anymore.
I wondered how the high speeds would work with a bed slinger, even my K1C is pretty noisy and shakes quite a bit printing at the higher speeds. To insure it doesn’t wiggle off the table, I’d put something to block it’s progress forward. If you don’t want to drill holes in the table, clamp a board in front to keep it from taking a leap.
My V3KE is pretty violent at full speed, but is a lot smaller mass so it doesn’t go anywhere. With that running and my Q1 pro I am surprised the cabinet they are on doesn’t shake itself to bits.
The rubber feet on my Ender-3 V3 + keep it from moving anywhere.
I guess it would depend also on what kind of surface the printer is on…
Something I need to watch though… Thanks for bringing that up…
Rubber mat is a great idea.
One little issue is that not all 4 feet sit on the table, one of them is about 1/8" off. I have something non slip under it for now.
I was trying some larger printed feet with some cabinet bumpers under them, but now that I look at them I see the adhesive didn’t hold, and they shifted out of place.
I’ll get one of those mats today.
I think by adding a long strip of wood with clamps (on the edge of the table) would stop it from falling off the table. If you can, use screws to hold the wood down…it will not move. It would also keep all the 3D poop on the table and not the floor.
I have 5 creality printers ranging from Ender 3 to the K1C . I’ve found that using a slide resistant mat under the feet stop the printer from moving during violent movement. Also with the K1C, I’ve had problems with my filament dryer ( Creality Space Pi Filament Dryer) the filament gets stuck causing a tug of war. Which caused my printer to move slightly as well.
I have had that with a tangle that I hadn’t noticed, it threw the dryer across the workshop, which surprised me.
I cut squares of the rubber shelf liner material like shown in 3D4Everyone post.
Made a double layer for each foot and that seems to be working so far.
I already made those. Didn’t seem to help, but didn’t make them from TPU. Might have to try again.
TPU with gyroid infill of about 20-25% should give quite a maleable foot with plenty of friction to the work surface and soak up vibrations.
I think the good sized rubber feet on the K1C certainly help it stay in place. I’m surprised they didn’t put good rubber feet on a bed slinger!
The matt works great for all my stuff they dont move with it under them.
I had to put a restraining order on my printer when I first got it. I keep it on the floor but toyed with the idea of printing brackets to anchor it but expected the screws would eventually pull loose. I recommend the floor (unless you live on the second floor of a rented unit). 
I bought a rubber style matt.
It stopped it from walking around the table when printing.
I tried printing Big Feet a couple times in TPU, never used it before. That was…different.
The first time I tried printing these feet I did it in PLA and they looked bad. Same thing in TPU. I suspected there might have been something wrong or corrupted with the file, so I recreated them and instead of the concave base, I made a half round groove around the foot base.
Now it prints out pretty nice. Still not perfect, since I need to work with TPU some more, but a whole lot better. Yes I used support under the groove.
If anyone wants a better copy, let me know.
I’ll need to track down where I found them exactly. I use 1/8” thick triangle pads under each contact point. One doubled up under the slightly risen contact. I don’t know what they are made of exactly. In your hand they feel like glue! It helped unbelievably with vibration, noise and movement. Before installed it, I would hear the printer 2 floors up at times during the night. Anyway, I’ve ordered these from couple different places with one being of excellent quality. It’s been roughly a year or so. I’ll track down the origin and post back here.
Well the feet didn’t keep it from sliding around. 2 layers of the rubber shelf liner is what worked best.
