12V Y Carriage Magnetic PCB Heated Bed MK52 Heatbed Hotbed Without Magnets for Prusa i3 MK3 3D Printer, with Cables, thermistor

This product is exactly as advertised. Bear that in mind as I describe why I gave it five stars. It is a stripped down mk52 12volt board for upgrading any prusa mk2 lineage. Converting using this board is not for light hearted and requires a working knowledge of the printer to get correct. First you need to reuse the screws and standoffs from your existing mk42 bed to attach to the frame or buy equivalent elsewhere. If you reuse you need to strip the pei off the old board to get the screws out which is bit tricky so suggest googling that. Others have posted that the power wires for the board were not compatible with the original prusa board. You can either reuse the previous board cables which involves soldering, or remove just the connector end of the old cable assembly band attached to the ends of the new bed cables. I did the latter which saved me a board upgrade and was easy enough to crimp the connector ends to fit into the screw down aspect of existing connector end. Finding the magents has been problematic as they are sold out everywhere. I have just used binder clips to keep the separately bought steel sheet down. This seems like a lot of work and it is. However the board works, is of high quality, and the price point is perfect for those that have the know how to use this and rebuild it. Do not buy this product expecting a straight up plug and play. I could not find a cheaper option for this quality and since I missed out on the prusa full upgrade deal which was significantly more expensive this was an amazingly cheap opportunity to keep me printer relevant and maintenance free for years to come.

Dislike - no option to include the correct glue for attaching magnets.Like - price, speed of delivery, accurate mounting hole placement, overall quality.

and I'm glad I got it, because printing with a magnetic print bed is a game-changer!Some words of Caution though! This may not work with the standard 240W psu that comes with the Prusa i3 MK2. I had to replace my PSU with a 360W unit, because the whole printer would reset when it tried heating this plate. I honestly thought this product was defective at first, but after reading several forums the actual cause came to light.Also, you will have to cannibalize your old build plate for screws and the thermister, because this doesn't come with them (the thermister isn't accurate with the MK2, from what I've read.)

This was a perfect fit for the upgrade Prusa MK2 to MK2.5S. While the heated board is great, it did not come with magnets and you will need to buy the correct ones and glue them in yourself.

I just finished the simple task of replacing my crappy PEI coated garbage heap of a heatbed that I never had any shortage of adhesion issues with this MK52 version. It's literally a drop-in replacement for the Prusa mk2 heatbed, and doesn't even require any firmware updates to start using.The heatbed also comes with a thermistor, which is completely different from the stock Prusa thermistor and WILL NOT WORK with your prusa printer, but you can still re-purpose it in a second printer running Marlin if you tweak the firmware to the exact thermistor parameters. The good news is that you can re-use your old headbed thermistor with no issues.The heatbed also come with a pair of shoddily crimped together cables and neatly caused a huge short on my board when the hot cable popped out of the crimped end. Thankfully the bed was off, or I would be writing a completely different review. Just do yourself a favor and buy silicone wire and solder it to the power pads on the board.Also, you have to purchase the spring steel sheet and high-temp resistant neodynium magnets elsewhere, although I suggest getting the magnets from somewhere other than amazon, as the listings for those magnets are exorbitantly highAs for performance, it works with no issues, and even heats up more quickly than the older heatbed. Issues, aside, it's the perfect upgrade to your old MK2.

And it was not damaged it works pretty good
