There's loads of things I want but don't need. A 73 Porshe 911 RS lightweight could be top of that but unlikely. If it's a simple design, i might be able to help. Holding a coffee cup of any size is simple, the difficultbit is how the coffee cup holder attached to the car. We have a Seat Leon estate, good car but can only hold one coffee cup even though it has two holders in the centre console. Put one coffee cup in and you can't put a second one in. Two slim cans of redbull yes. Two coffee cups no. Design fail. Rob

Great to hear the good news.

That's doubled the attendance then 😊

On the ender 3 you need to get the bed really level. If you have the magnetic mat, each time you take it off to have to level again. I would level using an ordinary sheet of normal 80g printer paper. You want the nozzle just touching and grabbing the paper over the printer bed. My Ender 3 had four screws under the bed and it drove me mad at times as I'd have it set for one area and it would be out elsewhere. That's jusy the way it is. You don't say which filament you are using. 230C is,hot for PLA. The magnetic mat is not that good for PETG as the filament sticks too much and can rip the mat Show pics of the temp tower and which filament you are using.

I'll start off. Rob Willett, been 3D printing since lockdown. I originally brought an Ender 3 Pro to build a CNC machine. I actually did build the CNC machine but found I preferred 3D printing. I now have two Prusa MK3S+ printers and print stuff for astrophotography. I tend to use Fusion 360 for design and am happy printing in PLA or PETG. And if you don't know what those are, they're the type of filaments that the printer uses. Happy to help as needed. Thanka Rob

Hi i thought I’d start a thread for those people who are interested in 3D printing. A number of people have 3D printers, some people need things printed, some people are interested but don’t know much about 3D printing and want to know more. Hopefully this thread is for you. Ask questions, help each other out and be kind. Thanks Rob

It was a cable problem. I had used a 3.5mm to 3.5mm cable and then stuck a 1/4" adapter on the end and plugged that into the Dwarf. Moving to a proper 3.5mm to 1/4" cable (not sure what proper means, but it was one I brought) and it all worked fine with or without the lightning cable plugged in. That confused me, thanks for all the help Rob

It actually looks like an earthing problem, if I pull the lightning connector out, the audio stops. If I put the lightning cable in but at an angle just so an electrical connection of some sort (at an angle) is made, I get audio. Going to check the 3.5mm headphone cable to 1/4" cable as I suspect my adapters are the wrong thing to do. Rob

Ooohhh, thats interesting and I hadn't thought about that, will check, I;ll check, thanks @Smanth Rob

Hi all, Just had a quick play with the Mod Dwarf and my iPad. Somewhat embarrassing this is a technical question and I can't think of the answer, to be honest it's more than embarrassing but I can't work out the issue. 1. iPad is connected to Mod Dwarf using the USB B port and goes via the iPad camera connector which has a USB A port and a lightning cable power connector. 2. iPad is also connected via headphone port (3.5mm) to input 2 of the Mod Dwarf. 3. iPad is running a simple drum beats program that I can hear through the headphone port. It is not MIDI. 4. Bass guitar into input 1. Pedalboard is prettty simple. If I play the drum tracks I can hear them in the headphones connected to the Dwarf. I can hear the bass guitar as well in both ears. If I disconnect the iPad USB connection I lose the drum tracks (connected via headphone socket) to the dwarf. I cannot see why the audio that goes via the headphone socket needs the USB cable to be plugged in. If I unplug the cable from the headphone it stops, I can hear it from the speakers, I plug my headphones into the iPad and can hear drums. Basically, I cannot play the iPad output through the headphone socket to the Input 2 port unless the USB is plugged in. Any suggestions? Thanks Rob

I’ve had mine a few months and it’s never failed. It’s got the latest firmware as well. Are you running it into a DAW or using it standalone? Wondered if that’s the issue. I use mine standalone. rob

I'm a few days behind you two, so I'll just slipstream along....

I was dimly aware of UTM, but I know Vmware as I run an ESXI server at home for firewalls and other Linux boxes. UTM does look good and I might well give it a go. ESXI is very good, used it for 20+ years in the background. VMWare Fusion Player is now free on the Mac, I can't compare and contrast to UTM as I don't know UTM. I'm also just going to stick to the modwarf toolchain to simplify things Rob

And 60GB is not enough to do the three builds rwillett@MD-Dev:~/mod_dwarf$ df -h Filesystem Size Used Avail Use% Mounted on tmpfs 391M 1.7M 390M 1% /run /dev/nvme0n1p2 59G 56G 0 100% / tmpfs 2.0G 0 2.0G 0% /dev/shm tmpfs 5.0M 4.0K 5.0M 1% /run/lock /dev/nvme0n1p1 512M 5.3M 507M 2% /boot/efi tmpfs 391M 168K 391M 1% /run/user/1000 rwillett@MD-Dev:~/mod_dwarf$ How did you get away with 64GB. It must be right on the edge. Oh well, lets have another go this morning. I only have 20TB of disk left on the network box. Will that be enough? Rob

Much the same spec as mine then. Depending on workload I might have a look tomorrow.

No big deal, rolled back, extended to 60GB and now loading the toolchain [INFO ] ================================================================= [INFO ] Installing GMP for host [EXTRA] Configuring GMP [EXTRA] Building GMP [EXTRA] Installing GMP [INFO ] Installing GMP for host: done in 28.07s (at 03:05) [INFO ] ================================================================= [INFO ] Installing MPFR for host [EXTRA] Configuring MPFR [EXTRA] Building MPFR [EXTRA] Installing MPFR [INFO ] Installing MPFR for host: done in 17.77s (at 03:22) [INFO ] ================================================================= [INFO ] Installing ISL for host [EXTRA] Configuring ISL [EXTRA] Building ISL [EXTRA] Installing ISL [INFO ] Installing ISL for host: done in 20.36s (at 03:43) [INFO ] ================================================================= [INFO ] Installing MPC for host Daughter in school so will leave it for a few hours as I attend that,.

Now back to step 0, apparently 20GB isn't enough for a dev environment Ran out of space, I never even thought about it. Oh well lets roll back and extend the disk space I'm sure that this is documented somewhere. As a matter of interest, can I do all of this from the command line? is there any need whatsoever for a web interface. I'm very, very happy with the command line, that plus Emacs is good. Thanks Rob

I’m just at step 1, building the dev end up. I left it a few hours ago and it was still building GCC. That’s under VMware on a M series Mac. Who knows how that will work out 😊 I do have other intel boxes I can use but let’s see how this one goes. Much prefer a command line TBH. might get to step 2 later in week

Thanks for this. Is the issue now that you can’t package it for downloading to the Dwarf?

I suspect between us we may manage to make it work. I’ve now built the dev environment but have not done anything else. what I was trying to find was a sample project that simply moved the input to the output and nothing to it. That should be the simplest project of all. rob

last chance for two free mats. I can't believe that nobody on Basschat has a Ender 3 Pro. They'll go in the bin otherwise. Rob

So pretty much like every other open source project .... I hate watching videos as well. I agree that they are pretty much useless for development. I like paper, I used to develop in C on SunBSD (and that shows my age), but behind my desk was approx 2M of ring binders with every command and system function documented along with examples. I recall putting together a proof of concept network sniffer in an afternoon as the code was all there to turn the network adapter into promiscous mode, and how the structs for each network packet was formatted. <sigh> Now I have to look at StackOverflow and work what actually works from what doesn't as my version of the framework is 1 minor version out. 64bit ARM Ubuntu is now installed in VMWare Fusion on the Mac, so I'll have a look. I saw the dependency list and noted ncurses and wondered what the hell used that. I suppose that could be the menu system on the Mod Dwarf. One advantage of VMWare is that I can snapshot it, load up some new stuff and try it out, and then if that doesn't work, roll back. The fact you thought that getting to the mod device is opaque is worrying. So you never found a complete here's "how to build a simple plugin that copies data from one input to the other and does nothing else and here's how to download it to the Mod Dwarf"? Thanks Rob
