We at TFM will start to put out our 3D Printers to produce as much face shield parts as we can. Parts will be delivered to FabLab for final assembly and delivery.
We will put to work our new finished 3d printer ( HCube CM3D ) and our lab printer ( Prusa mks3 ) that we used for prototyping other projects we had.
HCube is a HyperCube printer that was adapted to be as stable as possible. Built with 20×40 v-slot profiles, e3dv5 hotend and linear rails on all axis. By far it’s the most stable 3d printer we built so far. And printing this shields will be a stress test for it. We will try to print with it 24 / 7 for as long as parts will be needed. We wanted to improve it a lot more ( and trying to produce it with Romania produced parts ) before we announce it, but given the situation we are putting it to work as it is.
For some time we have a Tevo Tarantula 3d printer. Usually we keep it connected to a desktop computer and while we were printing we didn’t do much on it. However last night while printing a piece that took a long time to print we decided that we should use the computer. Big mistake. Computer hanged ( We assume something related to video card but that remains to be tested), printer hanged so we have to print that piece again.
You can imagine the frustration. Luckily we have several raspberry pi 4 around ( for a Kubernetes cluster project ) and we decided to take one and build a print server.
You will see a message like this :
root@pveg7:~# hponcfg -f reset.xml
HP Lights-Out Online Configuration utility

Integrated Lights-Out will reset at the end of the script.
Please wait while the firmware is reset. This might take a minute
At this point controller should be up again. Hope it helps.
