Maybe I’m putting too much tension on it? but I’m not sure how much is correct.
I first followed the instructions and attempted to fold over the end, but while adding tension it ended up pulling through the slot. So I changed to cut off a little piece of belt as it said was an option, which worked a little better, but then the belts would slip as it tightened up.
I have now glued the small strip to the end of the belt, but after tensioning it, it still seems to pull farther through than I thought it.
Re-reading the instructions, it says “set the tension just below where it makes a sound when you pluck it.”
So that sounds to me like it should be fairly loose compared to what I was thinking it should be, but that may be just from reading so many posts and people having issues with loose belts or suggesting loose belts could be a problem…
Anyone know of a video maybe that shows what I’m aiming for for belt tension?
Sounds like your printer might be oversizing that slot a little, or maybe your belts are a bit thin. I can barely get my belt into the slot on the X stub, let alone pull it through.
Before re-printing though, try folding the belt end over, and put something in the fold, say a short piece of a toothpick or bamboo skewer. For bonus points, you can leave the segment about 14mm long so it sticks out a couple of mm on either side of the belt. You should not be able to pull that through.
On mine, the stub passes very close to the YZ plate, so anything sticking out like that would interfere with homing the Z axis. I think the printed XZ plates left more room.
This was going to be my next try if this doesn’t hold, I almost asked in the last message if that would be ok.
I would be surprised. Everything else on all of my printed parts are exact, very snug fits. All of the captive spots for the nuts were very tight fits.
I got my belts from Ryan and they are a bit thinner than yours. Mine are 1.3mm thick single-layer, and folded over with compression they are only 1.8mm. As I was typing this I went and checked the model, and the slot is exactly 1.8mm wide, so I guess I will just go ahead with the toothpick and get ahead of it and avoid future problems.
It would still be good to get a handle on the expected tension also.
What slicer did you use when preparing to print those parts?
I’ve had problems where Cura in particular would make holes (Nut traps) smaller than designed, and simultaneously make gaps (Slots) wider. The various slicers even have features to try and tune this.
I’m not sure if that’s your issue, but comparing the part model with a measurement of the feature on your part would give some more insight. Have pictures to share of the belt in the slot? I believe this is a really common problem.
It’s not “done”, but it’s way farther than I thought I’d be at this point. I am loading up an SD card right now with the config, and at least should be able to drive it around hopefully and test all the stops, etc tonight.
A torsion box is extra rigid when joined to a top and bottom skin. Sitting a spoilboard on top, even if it’s screwed down in a few locations is nowhere near as strong as even a thin skin glued and screwed down.
As such, even something like 1/8" plywood glued down to the top surface will do wonders to keep the top of that table nice and flat, and I highly recommend that. Put the spoilboard on top of that. It would be well worth the effort.
A little odd, you can see at 0:44-ish, the machine pauses for a second or two before continuing on. I ran it twice and it did the same thing in both times.
First impressions of FluidNC web interface is that it’s kind of a pain if you don’t have a dedicated device. I only had my phone with me, and when I switched back from video, I had to fully disconnect from the AP and connect again to be able to control it.
The web UI is setup so that it’s like a gateway that auto pops up when you connect. So you can’t easily switch back and forth between web control and a different app from an iOS device.
Is it any easier if you bookmark it’s IP in Safari? (default config is 192.168.0.1).
The portal redirect is a bit of an annoyance, but that should let you dismiss the iOS portal page and then just refresh Safari.
With those settings, when I connect my iPhone to the Jackpot, I can just switch over to Safari and go to the bookmarked 192.168.0.1. Up comes the FluidNC GUI, no issues driving it from the iPhone that I’ve found so far.
I’m not home now, but I’ll try later. I do remember having to do this before for something similar.
It’s not really a problem, just a slight annoyance while I was testing. I expect to have a dedicated iPad there when a job is running.
Ideally, when FluidNC vNext is released, I’m hoping those fixes @jamiek submitted will help it run reliably in station mode so I can upload files from my office inside without having to carry it back and forth
@vicious1 - this should go into the v1e Jackpot documentation somewhere. There will be no shortage of iOS device users that will get bit by this.
The underlying root cause is that iOS is detecting the portal, but the iOS portal manager wants to see some kind of response from a server on an apple domain. If it doesn’t see ‘success’, then it never registers the connection as up, so the only option to the user is to cancel (which disconnects wifi from ESP32), only use the portal page to drive FluidNC (switching away again causes iOS to disconnect wifi from the ESP32), or to use the settings I’ve shown above.
If he doesn’t have time, I’ll make a pull request this week for this and a couple things on the Jackpot docs that I found could maybe help someone new to it like I am
My spoil board hasn’t been surfaced, so some of it didn’t cut all the way through in the middle.
I need to figure out more about FluidNC. I haven’t figured out yet how to cancel a running job, other than pull the power.
I also forgot to switch to poll mode so I lost the ability to even load the site once the job was running.
Overall though I’m happy with progress. I just need to back up now and fix up some of the wiring in a better state so I don’t have to carry it while the job running….
I’ll probably start printing some drag chain and work on getting the router connected to a SSR.
So hopefully by the end of the week I’ll have some more progress.
I have the timing changed, that should be fine. I can set it to poll in the preferences file if needed. Kind of assumed 3.7.7 would be out by now before I made any more changes.
