3D Rotary Printer: A Step-by-Step Guide - Space Engineers

[@SoundShunter72]

This one looks really cool and functional! Makes a lot more sense in survival, much better than just making a grid of welders on a piston.

[@pedropimenta896]

I will do the inverse operation: I will use a single rotor, in the middle, with a fully extended piston. As the piston retracts, the rotor will spin. The arms will do the retracting/extending as you'd expect.

[@doot4246]

@@termiusprime you do, but you have to buy your own private server and add the mods in server side. its an inconvenient workaround but it still exists :D

[@mikemarkwilka4135]

They also could not initiate FTL jumps. I think they could mine on their own but they'd have to be set up that way from the start, and could not expand. But with scripts... well, that opens up other possibilities. Even without scripts, you could have event controllers that detect the absence of a grid upon a proscribed circumstance. Which makes them build a replacement. So AI ships that have recorders to dock and undock and patrol on a schedule, but if they don't come back on schedule, new ones are built. Or interceptors are dispatched.

[@BookBurnersStuff]

AI factions have only one problem and that is the sync distance. Servers usually don't synchronize and run code when no players are around, making the space without players frozen. What we did on our servers is for example carrier type NPC's or hangar stations, which when spawned produce their own support craft. So players can't just deal with one and then wait for cleanup. They have to actively deal with the threat.

[@히히-p8u1k]

I felt that if the performance of the computer is not good, there are some parts that are not made because of the program block when making the middle part. If the performance of the computer is not good, I recommend removing the merge block part from the timer block at first, turning it off and on from the control sheet, and turning the printer twice.

[@spartanicus1337]

This works great on survival. Pay close attention to each step or you might spend extra time troubleshooting (like me). I really like this as you can change the merge block on top of the projector to a light armor block, use that to connect to the projector build, and then build your blueprint in more than one go with more materials. You can also use MMaster's AutoLCD mod to output the projector's remaining tiles to a screen to easily monitor your progress.

[@mikemarkwilka4135]

With more pistons, you could do this to weld a large grid. Time consuming, but more PCU efficient than a welding wall.

[@MRC673]

awesome and efficient, much superior to welder walls.

[@JarredRidley]

I love the design. I seem to be having issues with the printer arms not moving around the subgrid when printing so the welders get caught. I have set up the sensors as you did, and even though they sense the subgrid, they do not move the pistons. I'm going to try a few other ship designs in case, but thought I'd see if you had any ideas.

[@newdess467]

Do you have an idea for a bigger printer? I mean medium/large ships + if I want to extend the printer by one piston up, one to the side (on both sides) and give the piston to doo welders - so that they can go down when I increase the printer, how to do it with assigning an action? (I would like to print a larger ship

What's the point for the merge block?

[@Pro100tv9]

It's over there to hold the projected grid and easily detach it after printing

[@joshuabaker6971]

So it works as intended but it keeps detaching my ship before it is fully built and when i take away access to the merge block it will only weld to where it would have disconnected anyways. What do i need to change different blueprints

[@Pro100tv9]

Hey @joshuabaker6971, there's an event controller that checks piston position. By default it is set to 55%. At this threshold it will end printing cycle. If the ship you are trying to print is bigger, lower the threshold - for instance to 30 or even 10%, depending on the grid size, it should help

[@joshuabaker6971]

Yes that helped a lot

[@eliasmancias6163]

i built the plan step by step and when i go to trigger now for the start/stop timer it triggers the final timer, and turning it off from there messes with the other blocks, making arms go in and out

I don't get where's the problem.

Hmm, can you switch the merge block off while the printer is not running? I think this should help

[@Manuelando]

@@Pro100tv9 Nothing. The welders still not create anything. I even tried to hand-weld the projection (in admin-creative. Survival savegame) but the projection didn't react at all. Im still wondering how works te projector. First time i use it x)

[@Pro100tv9]

It seems like the issue is related to the projection that is not attached to the projecting grid. Perhaps the blueprint you are trying to print has its merge block switched off? If that's not the case, could you make a blueprint of your printer, upload it to workshop and post a link to it over here? I could troubleshoot it this way

[@NowThatsRadio]

Does this work for any small grid ship? Or is this thing tuned to your ship alone?

[@Pro100tv9]

It should work for most small grids. Sometimes, when a ship that you try to print is bigger, you will need to adjust the event controller slider or turn off the event controller completely

[@masochistpasta8807]

I tried this verbatim, following the steps to the T, and still have not been able to get the piston arms to extend/retract to print properly.

[@Pro100tv9]

Hey, are sensors "ON" when you start the printing cycle? If not, try switching them OFF while the printer is idle, and then start printing and let the printer go for a full cycle

[@masochistpasta8807]

@Pro100tv9 Sensors were in fact off when I triggered the start/stop timer block

It might be that you have both extend and retract on the activate side of the sensor

Does my blueprint need to have merge block at the end? Also for me I have to trigger multiple prints for it to fully finish the build, is that normal?

[@Pro100tv9]

It doesn't need a merge block, but you will need to grind down the connecting block between blueprint and printer once the printing is complete. I think the event controller setting may need to be adjusted to the size of your blueprint

[@docsnmschannel335]

I followed your instructions to the tee (video was great). However, it looks like it is working but nothing gets built. I took a video so you can see what it is doing. I usually use a metal sheet block to link my model to the projector. I have never used a merge plate. Do I have to weld a block to the merge plate? The merge plate is Red, I don't know if that matters???? Here is a link to the video kzbin.info/www/bejne/anSnn413ptl8oZY

[@Pro100tv9]

Thanks for the video, it helped me a lot to understand what is the problem. The projection is sticking to the projecting grid via the top of a drill - this will not allow to print it, because it is not possible to attach any block to the top part of a drill. Instead, try to rotate the projection 180 degrees, so it sticks to the printer via a light armor block (for example), this should allow you to print the craft.

It looks like it is working but nothing is being printed. kzbin.info/www/bejne/anSnn413ptl8oZY Thank you for the great work you do! Doc

[@Pro100tv9]

Hi Anthony, thank you for the video it helps a lot to recognise the problem! It seems like you are trying to attach the projection with the forward part of the drill, unfortunately it's not possible as there's no mount point there (you cannot attach any other block to this part of the drill). To solve this issue try rotating a projection 180 degrees so it is attached via (for example) a light armor block, or any other block that has available mount point

[@anthonydallalio5716]

Thank you for your quick response. I will try it and get back to you.

[@anthonydallalio5716]

That did it. However, it did not build all the blocks. It was just a few parts (a Parachute, 1 gyro and the reactor). also, when I filled my H2O generators and the hydrogen thrusters came on my whole base started to shutter. I thought it was all going to break apart. I jumped out and ground down the part attached to the merge block and it stopped. It is really neat but very unstable on a multiplayer server (which is what I am playing on). How do you release the ship from the merge block? I think I would need to do that before starting the thrusters. Also, when I checked that option you mentioned in your video to make it slower, it started shaking my whole base and this was even before I tried a projection. It was shaking just like it did when I added the ice to my O2 generators, so I unchecked it real quick and it stopped. So I can't check that option you mentioned at the end of your video to make it go slower for stability. Again thank you for taking the time to help me figure this out.

[@Pro100tv9]

I'm not sure if I understand it correctly - you did check the "share inertia tensor" option? Also I would recommend adjusting 2 things about the blueprint you are trying to print before printing it - toggle off its thrusters and add another merge block to the ship. Merge block can be attached to another blocks but can detach only from another merge block. The printer's event controller will detach the printer's merge block when the printing is done automatically if set to do so. About some blocks missing after printing - I think the only solution I can recommend here is to further slow down the rotors, it sgould allow for more precise printing

[@anthonydallalio5716]

Yes, I did check. “share an inertia Tenser”, but even with no projection up, the whole thing just starts shaking so I immediately unchecked that. So the answer is no I do not have that checked because I can’t do it without the whole thing shaking. I will try your other options. So you are saying that any blueprint that I use must have a merge block to use this printer correct? Most of the prints that I download do not have a merge plate on them so if you use a merge plate on your printer then you must have one on your blueprints, is that correct? Is it possible that I can get rid of the merge plate and just weld a block on like I normally do? Again, thank you for all of your input and I hope to get it working because I think it looks awesome.
