I was just replying to another commenter, saying that whereas my LR3 has 25.4 mm tubes, the LR4 uses anywhere from 29.5 mm up to 32 mm, cut from EMT rigid steel conduit (available at home improvement stores / hardware stores). Since those are more rigid, the rest of the design has been beefed up to translate that to a stiffer, better machine. The early reports from the beta team members are impressive!
@design8studio any chance of more z travel? I cut a lot of foam and pvc board and would love a bit more z. It's the only shortcoming of the lr3 for me honestly.
@@stephengolaski6451 That LR3 that you see me using in the video is mod’d: it has +50 more millimeters of Z travel height than the stock LowRider design However, while other CNC designs get less rigid as they move down into the material, by contrast, the LowRider design gets more rigid as it moves down to the material. This means that the normal CNC approach has a weakness regarding making deep cuts, while the LowRider design’s area of “not as much strength” is at the top of very tall, thick materials. However, if what you are cutting is not stiff (hardwood or metal) then you can modify the design to get thicker Z travel. However, another way to approach it is a drop table, or raising the rails that the LowRider travels on. There is a possibility for remixing the new version to allow for taller YZ plates like how Dan and I did on the LowRider v3, however, we’re deliberately not even talking about or thinking about mods right now until we get the stock version launched and understood.
@design8studio hmmm..any chance you would share the files for the taller sideplates? Are they in your printables? Yeah i was thinking of rails and or drop table... just hadn't settled on a design yet. Im doing a lot of signs and latge foam props so a 3" cutter woyld be great...one less glue joint
Yes. Go to the link below, scroll down to “Other Files” and get the “Vectors for DougDanTall plates” - I use the extra height mostly for access to get underneath the thing and for occasionally jogging it over thick items laying on my CNC table that I also use as an assembly table. However, if what you’re cutting is not super rigid, like in the foam category that you mentioned, you may well be able to actually get some cutting at the high Z range.- www.printables.com/model/805777-lowrider-v3-cnc-fenders-for-various-stock-tall-yz/files
Hi Doug, I was wondering what the start of the cut is like. Once the slot is made, I understand that trochoidal milling seems much better than conventional milling. I use Fusion 360 in CAM so I am having a hard time adapting to adaptive clearing. Maybe I'll switch to EastCam or at least to make aluminum cuts. I'm trying to cut my LR4 plates on my LR2 and I'm having a hard time.
So the start of a cut is like a spiral motion version of straight downward drilling, only far slower than you would think it would be. It’s almost maddeningly slow. But once it finally reaches full depth and hits into the forward-motion spiral-type cutting then it was worth the wait. I don’t know if there’s a way in ESTLcam to speed up how fast it’s moving downward, but it seems to be like it could afford to be faster than it is.
Thanks for the video. Are you able to get the machine to go faster on trochoidal? I am running the FluidNC and the software seems to not be able to go any faster than around 1000mm/min, which isn't fast for trochoidal. I think its a limitation of the FluidNC/ESP32, I think the physical machine could handle at least 2-3x that without shaking itself too badly.
@design8studio I didn't see a limit in EstlCAM, is it there, or do you men the Fxy for the tool? I have max_rate_mm_per_min at 9000 for X and y axes so I figured I was good there. Are these the settings you are referring to?
I reread my orig comment and should have clarified that I can get the machine to move significantly faster than that normally, but I turn up the Fxy to 5000 on trochoidal and it doesn't go any faster than at around 1000mm/min (ie, set on 5000 but feedrate overrides don't make a difference until around 20% which I think means the software is maxed out).
@@GSeymore In ESTLCam there is a governing max speed limit in the settings. I am not at home right now, so I can’t verify by looking at my computer. But if you go into the settings, you can set that max speed up. Similarly in the FluidNC config file there is a max speed that you can raise.
@@GSeymore I just read your clarification, and I had noticed that forward movement during trochoidal milling is slower than the rate shown, and I just assumed that the rate applied to the speed at which it’s doing the orbital motions, and that the forward motion was some kind of fractional calculation based on that orbital motion. I could be wrong. I guess I need to look into that some more.
So first time watching channel, and some solid content. I had an idea which maybe worthless. Would it be helpful to have a 2" vacuum hose near the milling head to suck away the chips while the machine is operating?
Yes, and normally I do that - but mine's a 2.5" hose. You can see the mounts for it in the video (to the left side of the motor mount area. I took it off this time primarily so I could watch up close to see what's going on, and to allow the viewers to see as well. When the dust collection shoe is in place, it obscures the view quite a bit.

Seems to me the v3 is the same machine as the v4. I dont think the rails on the v3 are are flexy at all especially if stainless tube was used. Where is the big improvement?
There are improvements across everything, which although each one may seem minor, all accumulate to a better machine. Starting with the gantry, my LR3 had 1" OD (25.4 mm) stainless steel tubes. The LR4 has either 29.5 mm OD (EMT is sold based on ID, so 1" EMT is 29.5 OD), or 30 or 32mm steel tubes. The larger tubes are stronger than smaller, even if the smaller is stainless. The rest is a lot of tightening up for rigidity, beefing were more beef was needed etc. This gantry is more rigid than my LR3 gantry was. Cuts are being made with stock LR4s that were not doable with stock LR3s.
Ryan is working at a feverish pace to get things ready to show to the public. There is no set deadline, however, there is a thread on the V1E forum about the status of the LR4, and so you might subscribe to that thread, and watch there for updates.
Sure. I paid $25.79 (USD) for that piece on Amazon several months again (November, 2023) and today it's selling for $26.79. Here's an affiliate link to the listing. amzn.to/4fxTkEd
The wildcard here is how long before the V4 comes out. It could be weeks or months. The good thing is that the hardware kit for v3 will be almost identical to v4, with the only difference being a few screws. The other differences between v3 and v4 will be: different printed parts, beefier EMT tubes (larger diameter), and shapes of flat parts (XZ plates, strut plates) are different. Finally, the YZ plates were a flat part on v3, but they become a printed part on v4. The consensus advice is to consider building the v3, learn the ropes, do some cutting, and when v4 comes out, you could use the v3 to cut the flat parts for v4, and reuse the hardware kit.

I am so excited to hear of a new and improved lowrider. I am building a 9 by 5 work bench and the new version will be very welcome.
Cool!

@@design8studio That makes sense
Nice big chips! Cheers for 3:35 settings that are working for you. LR3 with gantry sized for up to 4' wide cuts? 1" DOM steel pipe?
Yep, LR3 wide enough to cut 49" wide MDF (or 48" wide plywood) and 1" DOM steel tubes on the gantry!
@@design8studio your wide gantry makes the cutting depth all the more impressive to me. Cheers!
@@AzaB2C No joke. I'm still amazed a DIY machine this wide and this affordable can do this!
