Finally finished, its my first attempt at building anything so learnt a lot, 3d printing wasnt perfect on a few pieces, I am now printing only in PETG which seems to product far better results for me on Prusa mk3s In my opinion only things that can be much better in the motorised version (which is my next build plan!) is the parking brake seems very hit or miss, I think i need to reprint the bracket , almost like something isnt lined up correctly, I would much prefer the NG parking brake design on that - which is probably more simple Also the speedbrake handle isnt anything like the original which is much more flat and rounded. The text on parking brake handle, and the side of the throttles would be nice to have STL versions without so I can print stickers and put them there - I think it looks way better than 3d printed text. And finally would be nice to have a way to attach a small clamp somehow on the front so i can attach to the table and use it without pushing the whole thing around, although if i go full on simulator build i would screw it down from inside the end caps i think. All in all, kept me busy for a few weeks while work is slow and enjoyed every minute, thanks a lot Karl!
Stunning work!! I have printed most of the parts, now I need to start putting things together.
I was so looking forward to starting to print the new throttle until I noticed it needs a c10 size print bed…. ðŸ˜
Hi Sarah,
I just took a few days away from the Sim and I am now catching up. First disclaimer from me! I have 6 rolls of PETG but have never used it yet. Are you still using the standard 0.4mm nozzle?
Disclaimer 2! When I remove the nozzle with filament in, I always heat the nozzle up to operating temperature and use heatproof gloves and a 6mm ratchet to remove the nozzle. It usually comes away very easily. (Dont burn your fingers. I say this because so many people do!)
As for the parts failing, thats how they usually fail for me, I always check the printers before I go to bed, make sure the smoke alarm works above them and then wait until morning. Usually, the printers clog and the partial print is left with the printer still going on its merry way. Worse is the spaghetti monster comes to visit.
I am just starting to learn with PETG and so far my results have been less than consistent, sometimes disastrous. I know that you have to use higher heat with PETG but all of the references seem to differ widely on just what the best settings are. I am using an Ender 3 V2 with Cura for the slicing. What are you using and what settings have you found that are working out for you. Any information you can pass along will be a big help.
Right now my printer is shut down as the print head seemed to have jammed up and stopped feeding, the extruder eventually ground through the filament and now the feed tube is full of filament and will not release from the print head. I tried to remove the printer nozzle using my metric crescent wrench but the nozzle refused to turn. I have a proper set of metric wrenches on the way from Amazon along with a new hot end so one way or another I will get the printer back in action. It was kind of funny when I checked the printer after leaving it overnight to keep running, the part only printed for about the first inch but the print head was about two inches above that dutifully moving as if it was still working.
Hi Chris!
Great feedback and thank you! Sorry to hear you have had issues with the parking brake. Not sure what's going on there, perhaps the fits are a bit tight.
Moving forward, I will now included non raised text STLS.
I will also see if I can add a screw clamp to the base unit in the new V3.4 mods.
I have added both of these points to my to do list.
As for the speed brake, I took the dimensions off this throttle:
I'm guessing the design has changed on the newer NG and Max variants?
Hopefully you will like Version 5 throttle, this is already a monster unit and have worked every spare moment I have on it. But i can this being a very fun build.
Kind Regards,
Karl
Nice Work, looks Great
That looks so good. Nice job!
Awesome work on that Chris!
