I recommend you the Orballo MK42 heatbed. The bed from orballo is made in pcb fr4 3.2mm like the original. Be careful with the aluminium mk42 heatbed from aliexpresss. With aluminium the autoleveling dont work really well and of course will not work the XY calibration. The quality of orballo mk42 heatbed is the same as original. The shipping was really fast.von Dan_1986 - Prusa i3 and variants
hallo, Ich kaufte ein paar Monaten die Struktur. Gute Qualität. Der Auftrag wurde in 3 Tagen durch UPS geliefert! Sie haben auch eine neue Struktur http://orballoprinting.com/en/home/115-prusa-steel-v4-300x200-mm.htmlvon Dan_1986 - Mechanik
Hi! I made a order some month ago. The experience was very good. I bought my second frame to my new printer from orballo printing again. In this case i bought a 300x200 frame because I need more print area for big pieces. The delivered time to Germany was 3 days, Impressive! The frame has holes to fix the bowden extruder like the 2.5 version.von Dan_1986 - Prusa i3 and variants
Hi! I ordered a Prusa Steel 3d printer from Orballo. I received it in about 5-6 days and well packaged ( candy bag included! ) I'm very impressive with the laser quality of the frame. The parts fits correctly and is very robust. I'm doing my firsts prints. I will share my progress. Greetings!von Dan_1986 - Prusa i3 and variants
