excellent tutorial Chris, as always 👌😎
Thanks so much for watching! Congrats on your success with your videos, they are always very entertaining.
Great Video, Chris! I appreciate your efforts!
Thank you
Thank you, I just received my upgrade kit a few days ago and I will be upgrading shortly with your video.
I hope it helps. Thanks
I don't have a MK2, but I like watching the older machines getting up to date... That was a great benchy! Thanks!
Glad you enjoyed!
Thanks for the video chris this will help me out when i goto do mine
You bet, thanks for watching
Thanks for this amazing video, Chris! I’ve just completed my 2.5 upgrade following your video, everything is perfect! The only problem I did have, was seating the nuts into the PETG, it was a right pain to do, especially on the circuit board cover where the wire Loom goes in at the top! I’m just about to build an enclosure, and will be following your video on that too! Thanks dude!
Awesome, glad the video was helpful. Yes, the ones on the door are the worst.
amazing video, thank you for your help!!
Happy to help, thanks for watching!
I am going to use your video to upgrade my mk2s to mk2.5s, I ordered the kit on the 2nd last time before they discontinued haha, thanks so much this is so perfect and modern
Great, good luck with your projects!
Nice video, I've been working on rebuilding my first 3d printer, A Prusa I3 Mk1 clone.
As I work on it I am amazed at just how far 3d printing has come comparing it's features to my Ender 5 pro. lol
No kidding, it's amazing what just a year or two can do.
4:23 Super pinda. What a cursed name they picked :D
There are a few names out there that have this same problem. ;) Mingda for example.
I don't own a Prusa but who cares, it's a Chris Riley video to help me through these winter nights😊
I'm here to help! Thanks
Great video, I hope there is a video to get high quality print resolution
I am currently working on some prints with a .25 nozzle.
Great instructional! I just stretched my Mini clone to a 180x250 bed. Maybe we can look forward to a video on how to build custom firmware for it (and the MK3S) to take advantage of the additional build volume/custom setups?
This might help you. th-cam.com/video/rn3sv8M4CvM/w-d-xo.html
The bed power wire(red) has damage! exposed copper of the old bed. Good thing you are upgrading!
Yeah, I have patch that thing like 3 times.
@@ChrisRiley I just upgraded to 10 gauge on both my version of log and my ender 3. Both of them the wires were getting too hot and breaking in spots. Figured the 10 gauge would help with both problems.
Thanks Chris. I might actually go this route instead of the MK3S upgrade path since full kits are no longer available. It's really only the magnetic sheet, extruder and fan that are killing mew right now. Cheers, JAYTEE
Awesome Jaytee, I'm glad this was at least some what useful.
@@ChrisRiley Indeed it was. 👍
Thanks for another great video. I have an original MK2 (not even a 2S) that I have procrastinated upgrading for too long and apparently have missed out on the official Prusa upgrade kit. So, how about doing another video on upgrading Mk2 to Mk2.5s, but this time using third party parts for those of us who missed out.
The hardest item to find appears to be the 12V Mk52 heated bed. There are a couple on Amazon with and without magnets, but dozens of others on AliExpress. Some of the comments indicate compatibility issues between Prusa firmware and the supplied thermistor. That would be interesting to see you sort out. I think such a video would be well received.
Those beds have been hard to get and expensive. I got mine from Prusa, but it was around $90.
@@ChrisRiley I found a Mk52 12V heated bed with magnets for $56 on eBay and have ordered it. (www.ebay.com/itm/254951801505).
AliExpress has the same item from numerous vendors but with much longer lead times. Apparently there may also a version of the MK52 heated bed with connections for both 12v and 24v, but that was not well documented in the ads. So I was wary.
Other parts needed for the upgrade that I found on Amazon:
(1.) PINDA v2 probe:
(www.amazon.com/P-I-N-D-Sensor-Leveling-MK2-5S-Printer/dp/B07ZVLJPDY/
the filament run out sensor from Amazon)
(2.) filament run out sensor:
(www.amazon.com/IR-Sensor-Filament-Magnets-Printer-Upgrade/dp/B07PYQWGK1)
(3.) metal gears for the extruder:
(www.amazon.com/BCZAMD-Printer-Accessories-Extruder-Extrusion/dp/B07SW8HCL4/)
(4.) Noctua cooling fan:
(www.amazon.com/Noctua-Cooling-Blades-Bearing-NF-A4x10/dp/B009NQLT0M/)
I am still debating changing out the original steel rods and linear bearings with polished/hardened rods and upgraded linear bearing. Also replacing the cable tie mountings of the bed support with "U" bolts. These are also available on Amazon. What are your thoughts as to whats to be gained in doing this?
I think a video of how to hook up and configure these 3rd party parts to effect the Prusa i3 mk2 ---> i3 mk2.5s upgrade would make for an interesting video and would be a great contribution to the community, especially for those of us who missed out on the official upgrade kit. I am sure there is going to be some compatibility issue to be resolved to make this a successful upgrade.
@@alanoestacado That would make a good video, Prusa was trying to build a BOM for this, I need to get an update on that.
A screwdriver is no hammer :-P
The update to 2.5 is definitely worth it. Did it a longer time ago. Last Dezember I upgraded to the 2.5S but I wasn't that happy with it, because I find it more complicated to take the Hotend apart.
If one doesn't want to print transparent filament, it's better to stay with the 2.5.
Sure it is! ;) Same hear, I am loving it so far.
Great video! I did my 2.5 upgrade just after Christmas and it was worth it just for the magnetic bed and firmware update alone. Next up is a VMOD silent stepper upgrade. As I got my parts in for that.
Nice! I am loving my upgrade so far.
Dang , I wished you did this 3 years ago , I upgraded mine waiting on a cure for MMU2 (replace extruder with Bondtech) .. now that you upgrade it , what about an upgrade to SKR board or something to quiet these dang stepper .. As always Great video
Thanks Dan, that might make a good upgrade. I will see what I can do.
Hi Chris, could you make a video or give me a reference to study, explaining the difference between different types of bed leveling. like linear , mesh, bilinear. I made a bear mk3 clone with 32 bit board and looking for the most effective bed leveling technique. I am having first layer problems. it could be the fystec pinda 2 being inaccurate probing or measuring temperature. I just wana rule everything else out before I buy another one.
There really isn't much of a difference. The biggest one would be UBL, but for your issue I would look at running some probe consistency tests. //#define Z_MIN_PROBE_REPEATABILITY_TEST
LOL- I got that upgrade back when it first came out. Was waiting for something to break so I was forced to take it apart and do the upgrade then. It just keeps printing....
I know what you mean man, It always hurts to pull a part a working printer.
I just completed this upgrade and I am running into one issue that others have mentioned. Have you had any issues with thermal runaway on any prints due to the new setup of the print fan? Seems to be a common problem. Prusa chat mentioned to try and lower print fan speed, but others mention that lowers print quality. So most recommend a silicone sock. Have you had any thermal runaway issues? (hotend cooling too fast due to the new angle of the print fan once the print fan kicks on)
I haven't yet, but I could see where that would be a problem. I did see it on my Prusa Bear build. I did "fix it" with a sock.
I also have this problem. I'm thinking of using a silicone sock in the hotend, but some people already complaining about the sock not fixing well or melting over time
Can you still use the old PINDA if you don’t have the new superPINDA?
Yes you can, shouldn't be an issue.
Do you think the parts would be strong enough if printed in a much higher resolution and with ironing?
Sure, they should be.
Where can i get the magnets for the filament sensor
The best way to get them is in the sensor kit. They are hard to find by themselves. www.amazon.com/IR-Sensor-Filament-Magnets-Printer-Upgrade/dp/B07PYQWGK1/ref=sr_1_1_sspa?crid=37U8RGQTX4GY7&dchild=1&keywords=prusa+filament+sensor&qid=1634295910&sprefix=prusa+filament+%2Caps%2C194&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExNDZVVFpRTEtPUjRBJmVuY3J5cHRlZElkPUEwODkwNTg5MTBKSVZYUTdRM05IRCZlbmNyeXB0ZWRBZElkPUEwMTE4MjU2M0gxUVhFVUpLNERISiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= Amazon Affiliate.
bashing my head, i finaly got around to upgarding, new heatbed got the hotend all printed and everything wired, and i get a left hand fan failed error, calbes are good, try a different fan, same issue, bu a gunine noctua, still the same issue, I'm ready to through this thing in the trash!. the fans are all good, with the correct voltage. any help
nm i just figured it out! stupid V cable switch.
😁👍
Would to be possible to Just upgrade the Bed and not the extruder?
Sure, you can get the 12v beds from Prusa. Not sure how the pinda location effects the calibration routine, but I think it's the same as the MK42 bed.
Thanks. I did this upgrade some time ago, and am re-calibrating it after it being shelved for a year or so. I got an error message "Calibration Failed check the axes and run again." while going through the calibration wizzard. Do you have a video or pointer on how to do the axis checks? It passes the z axis calibration.
I have been over all I could find on the Prusa site. Any help is really appreciated. I have loaded the latest 2.5S firmware, 3.10.0 at this time.
It's probably just a bit skewed. Make sure the frame is 100mm away from the back feet. Make sure the probe lines up in the center of the front leveling spots on the bed. Pay close attention to the one on the right.
@@ChrisRiley if the probe isn't in the center of the target spot (even the first one), how should I adjust it. The PINDA is 1/4in left and forward of the spot on the target. (viewing everything from the front of the machine). And thanks for your help. It is appreciated.
@@servant74 Scratch that, that's not the same on a 2.5. The probe should be in the front 2 white lines when the Y endstop is triggered. You might have to adjust the center belt tensioner back or forward to get it there.
Just wondering If I only switch the bed, will it work? Do I still need to do firmware upgrade?
If you just swap the bed no firmware change would be needed.
@@ChrisRiley thanks for your response. Appreciated.
Are you sure you are supposed to change hardware setting to super pinda? i did this kit a few months ago and didnt change it, i watched this video and changed that setting and it wont calibrate xyz with it set to super pinda.
Do you have the 4 wire pinda? Maybe it's a v2.
@@ChrisRiley oh yeah, i think it is just a v2..
I tried for years to get an mk52 bed for one of my Prusa's, every time I tried buying one they were either out of stock or unavailable, even the main supplier for Prusa in my area which is Voxel Factory was never able to get a hold of a spare one for me. Eventually, I just gave up on the idea of an MK52 12V, now they do have them in stock at Prusa but the price has gone through the roof in comparison to what I would have paid if I was able to get one at the time. Who in their right mind would pay 100$ USD for a headed bed FFS lmaoo
Yeah, they are pricey, I wonder if Orballo still makes one? I will have to check.
@@ChrisRiley They do Chris, however, they are almost priced the same. Thank you nonetheless, Beiseds I got used to the idea that the Prusa I had made years ago will never see a bed upgrade. you know its bad when you can pay less for a 400X400 bed than one nearly half the size lol
I wish Prusa sold a bigger bed printer.
I think we all do. Hopefully, we will see one this year.
Friend please give me an orientation, after almost 2 years trying to have my printer I got all the parts already assembled the mechanics of the prusa mk2.5s, but I don't know how to upload her firmware I thought it was just download slicer and flash update, but no how can I put firmware on Rambo, would it be via arduino? Guide me if possible I'm looking forward to running this printer. I thank you in advance.
You should be able to use Prusa Slicer.
@@ChrisRiley Chris, I did it through arduino upload, on geithub it was also updated for mk2.5s I did it for your previous video (I3 Log). Thanks.
Mmmmmmm old Gummie Bears, still better than no Gummie Bears! - Oh holy yucky heat block! put your sock on. LOL
That's true! Thanks for watching
MK2.5 to 3S next?
Working on it!
i love the clones, lol
Thanks!
