[@Chefmagnum88]

Thank you so much for all the selfless work on this awesome project!

[@MihaiDesigns]

Thanks Charles, glad you enjoy it!

[@digitalkid56.]

Finished the 1.1 build today, got everything calibrated and working properly! Just wanted to say thanks for all your efforts and hard work! Your tutorial on setting everything up was perfect! Very detailed and did not miss a single step.. I was able to follow along and got everything printed on the very first assembly attempt!

[@MihaiDesigns]

Wow nice work!

[@przemysawsolich9896]

Great initiative. Ton of work and self learning process. Thank you. I will give it a try.

[@kthec1298]

i thank you very much for this extruder, i built it yesterday and im so happy, i used a different part cooling shroud tho, it was postet by some one on thingiverse under your extruder there, now i have so much better overhangs and overall the new extruder looks so cool, best feature is the fast access to the hotend, NO MORE problems with cleaning the bondtech gears and much easyer access to the filament sensor keep up the amazing work and cant wait for you to release the filament box

[@MihaiDesigns]

So happy to hear! Have fun with it! 🥳

[@jordifernandezarmenta13]

thanks for everything, love it !!

[@MihaiDesigns]

You're welcome. More updates coming up.

[@guinhill]

Sir, you have gone above and beond the call of duty. Thank you for these comprehensive guides. I think your extruder is the best thing to hit the Prusa i3. now to find the time for this project

[@MihaiDesigns]

So nice of you. Only do the mod if you really need it; it takes a while to assemble.

[@K12SXXFire]

Thank you VERY much ! Can't wait to try this !

[@MihaiDesigns]

Enjoy!

[@AdrianLuben]

Very good, well detailed video! I feel that you analyse and design them better than the manufacturers 👏😎

[@MihaiDesigns]

Wow, thank you!

[@MySpeedVision]

All I can say is wow, PitStop extruder is working fantastic. Extruder motor stays cool as a cucumber… Noctua fan is dead silent, magnets work great, prints better than ever before…. Fun to print, fun to build and your videos cheer me up when I’m having a bad day!

[@MihaiDesigns]

I'm glad you're happy with it. Working on a new design and it's taking a while.

[@geordieboy77]

This is amazing, congratulations on this design. Have you had any requests for the hemera extruder?

[@geordieboy77]

If you need a hemera I could loan you one if required

[@MihaiDesigns]

Can't remember such a request. Geared extruder is a different beast, super hard to do with magnets. Maybe in the far future...

[@GoranMilici]

i got all the stuff from the bom list and now just need to put it together

Awesome. Have fun!

[@ayourk1]

For the Quick Change Extruder that I use, we were using Micro DEANS connectors for the 2 hotend pins: www.amazon.com/dp/B000BOTWJU

I have found that the Magnets appear to be available thru Ebay.com. I have placed an order for 20 6mmx12mm N50 magnets. I hope they work!

[@MihaiDesigns]

Cool, thanks for the info! Those should work.

[@reality-builder7909]

Thankyou! I thought about switching to the dragon hotend however because of the better heatsink cooling I decided to stick to the V6 but get brass copper plated heat block, A bi-metal heartbreak and a 50 watt heater cartridge + new thermistor and IKO bearings because I want to be able to reach at least 350C extruder temp (all these parts are from triangle labs) these should all replicate the dimensions of the V6, I will try to get the highest possible temp plastic to print the pitstop with, do you have any recommendations? or is it possible to print PC on a stock m3ks. cheers!

[@MihaiDesigns]

Cool! What kind of materials do you plan printing at 350? PEEK and the like? PC is probably the best affordable material for heat resistance. You might be able to print it on a stock extruder, but I expect permanent damage and parts melting at those temperatures.

[@reality-builder7909]

@@MihaiDesigns My plan is to be able to at least print pure PC, I may look into the other filament types but PC looks more comforting to use than Peek or PEI, I think I will try to print the Pitstop extruder in the purest PC blend available for a higher temp resistance, I was initially going to do it in ABS because it is the lightest material available, petg is one of my favourite but it very heavy, heavier than PC.

[@brianfoster7064]

Would you look into creating a version that accepts the Precision Piezo Orion, please.

[@MihaiDesigns]

First time I hear about it. Is that a pressure sensor for probing? I'd look into it if it becomes more popular. I'll keep an eye on the requests.

[@brianfoster7064]

@@MihaiDesigns it's a bed leveling sensor. Unlike the others, it is very small and doesn't require any off-sets. It straddles the filament tube above the hotend, but below any DD extruder. www.precisionpiezo.co.uk/product-page/precision-piezo-orion-kit

[@Sembazuru]

If you are looking for a replacement part cooling nozzle, check out the RHD nozzle. He designed this nozzle using airflow simulations to get good air flow at all directions around the nozzle. There was a long thread on the Prusa forums about the designing of this extruder. It does require a slightly different mounting angle for the fan (and comes with a replacement bracket for the stock Prusa extruder assembly). This might be a good candidate to remix for fit for your PitStop extruder. www.thingiverse.com/thing:4124587/files

[@MihaiDesigns]

Yup, I think that's the best part cooling shroud I've seen. I'll try adapting it if nobody else does.

[@Sembazuru]

@@MihaiDesigns Someone beat both of us to this idea. Check out www.thingiverse.com/thing:4624355

[@MihaiDesigns]

@@Sembazuru right, I forgot about that one. It does use countersunk screws with an adapter, but should work.

I would be interested in alpha for your x and z redesign. I have original MMU2S, let me know if you need any help.

[@MihaiDesigns]

I've published the X ends that go with the extruder. Is that what you mean?

[@klemenzupancic]

@@MihaiDesigns I meant that what you say in the video that you have an idea that would require a complete redesign of x and z.

@@klemenzupancic Oh, I haven't worked on the redesign as there hasn't been any interest. Having said that, I might start a larger project that involves this redesign.

[@klemenzupancic]

@@MihaiDesigns No rush :) let me know if you need any help, if and when you decide to start the work. Good luck with everything and thank you for sharing!!

[@lorddingo3]

what is the point to switch from PETG to ABS/ASA to printing pitstop,, original prusa is with petg and look good, pitstop use better cooling then should be also better with petg

[@MihaiDesigns]

It's only for enclosure printing.

[@brandonallen2372]

PETG is generally fine if you aren't running your Prusa in an enclosure, but I did couple of back-to-back 3 day long prints in ABS using my Prusa and it warped the Extruder body (especially the PINDA mount) on my MK3s. I'm using the Bondtech BMG extruder now (their products are printed in Nylon using SLS) and I've had no such issues with ABS prints.

[@MihaiDesigns]

@@brandonallen2372 yup, that tends to happen if you print ABS.

[@FischOderAal]

You make me feel sad that I am happy with the Skelestruder. Otherwise I would try out your extruder immediately!
