I found I can do it with 3D builder from Microsoft. Works good. I'm now looking for the front corners with the feet on them. I find the four corners but I don't see the feet. thx

 

Yo Keith! I have tuned and calibrated and set up my printer now. Yesterday i uploaded the XYZ_Cube and tried to print it. The nozzle didnt touch the bed and the result was bad. I upped the bed temp and got the filament to stuck. it was good. I also needed to add some baby stepping. But when i continued the print the result was really bad I quess its the z steps per mm but my calculations seems right. I really need help i dont know what to do.

 

Ohh i got it to work. I used the prusa reprap calculator for zsteps per mm and got a value of 1600 with T8 2mm pitch rod and 1:1 gear ratio. But with some calculation i found out that 400 steps per mm was right. Dont know why. But now i got my first calibration cube ready and it looks pretty good. there is some oscillations that can be seen on leyer lines and i need to adjust the initial layer speed to 10mm/s to get the filament to stuck.

 

Jumpers? Im using duet 2 wifi and the microstepping is set with gcode in config. I have set it to 16x with interpolation. Im using petg and the first layer height is 0.4mm. I think the problem is with bed adhesion so it has nothing to do with the build itself im running some tests today and try to calibrate the accelerations and jerk settings. This build is great! i did make some artistic changes that did not make the build any better... But im happy to got something working.

 

PETG is the my bain! I have so much problem with first layer adhesion. Sometimes it adheres and sometimes it doesn't even when I don't change anything. Once it adheres the part comes out marvelously.

 

Hello everybody here.
I'm quite new to 3D printing, and I'm thinking on building my first printer.
I'm taking a deep look into this beautifull project and at first glance 2 questions came to me.
There's no need for a belt tensioner in any of the printer's axis ?
Would the printer get any profit on using a 0.9 deg stepper motor on the Z axis or is it useless taking onto account the manufacturing precission of the Z axis M8 threaded rod and the nylon M8 nuts ?
Sorry if my comments looks stupid, I'm quite experienced on mechanics, but very poor in 3D printers

 

Thanks a lot Keith. I really apreciate your comments and your effort to answer me.
I know you're having a bad time.Please, get better

 

I'll be expecting your new releases

 

I like the BldrBot design Keith. I'm just starting to get up and around after the leg surgery. Spent the last three weeks mostly in bed with the leg elevated and heavy meds. Still cant' sit up very long because of the swelling. Think about you often. Guess you are kind of my inspiration and a mentor, when I start feeling sorry for myself for a bum leg I think of you and how it could be much worse. Funny I don't even know you but connected with these printers somehow. Cut all the aluminum and set up three workbenches in the living room before surgery so ready to start assembly of my Vulcan. Can you share your Marlin configuration files? Have been spending time going through all the options in Marlin and Cura that I really didn't understand before. (Not that I do now, but a little better maybe).

Thanks Sam

 

Yes, people ask how I can sit a drive for 11 hours a day after day. That seat is incredible, heating and cooling, everything adjusts. My wife passed with ALS and I got to see some really high-end chairs. Can always be improved on, but you got some work to do. I was always amazed at the ones that could jack up the person so they could see over a crowd. Talking in the $20-30k.

On the Vulcan, on the BOM you call for 2-20x20 cut at 440mm and 2 at 460mm. Step 8 is calling out 2-480mm. Also, step 22, M5 x 150mm screw. That is a really long screw. Might want to look at that.

I edited post 77 when you were sending. did you see step 22?

 

Hello is the max the better build? I see there is a pro as well
was just about to start building my own and saw this looks like a good buid
can someone please tell me if this is built with commonly found parts i have lots on order from aliexpress i was aiming for a build of a 328mm bed
thanks

 

hello
i have been ordering the parts for this could someone please tell me the following thanks

1meter? s this correct should i order 5metres?
1080 belt 0.1 35.00 3.50 976mm or 1000mm closed-loop gt2 belt - RobotDigg 1 meter

is this correct?
GT2 16T 5mm 5pk 0.2 9.96 1.99 https://www.amazon.com/Saiper-Aluminum-Synchronous-Compatible-Printer/dp/B07MN2C5WJ

 

thank you keith can you please tell me if this is the best printer out of the from the designer the vulcan max ? as ive seen a few there is a pro? as well

1, Not sure on what thread size to g for the y axis screws? is it best to get the finest pitch one there is a 2mm one for better accuracy??
2, ive also seen white bearings? are they the best ones?
3, what size are the 2 vertical vertical screws? 5mm dia, not sure on pitch 2mm?
4, what size is the bed screw 8mm? not sure on the pitch 2mm?

thanks

 

thank you keith, so the x axis is 2 x 8mm is the bed screw 8mm also

 

Great I get it now thanks for helping me Keith

I don't have a printer at the moment, is there any brackets that are available to buy for the fixings on the x axis bar fot the hot end and fixings.
Really impressed with this design think it's the ultimate.
I'm from the UK BTW are the plastic parts available to buy or Maby I could get them printed somewhere Maby
Thank you

 

Thanks so much
