Send me an email and we can talk if your interested in just running the same setup. I have gt2560 rev a in stock. Online store is georges3dprinters.com 45 yeah I know the store needs work, soon… Can email me at george@georges3dprinters.com if your interested in buying and have some technical support to go with it.
Impressed with that too. Also been watching to see if/when their “MK42” board becomes cloned and available at cheaper prices. Prusa Research never seem to have it in stock by itself yet due to such a demand for the whole printer.
Interesting how their open source views are becoming more “fenced in” to help sell their printers. I’d love to buy the new addons such as the new bed and the multicolour setup as separate items and add them to my own setup, but it seems for now you need to buy into the whole “Original i3” system to benefit from all of Josef’s cool upgrades and developments with the least amount of headaches and cost.
I can’t ever remember his last name, thanks for that. I used knock off in the context it was being referred to at the comment, in response. I agree with your statement of open source hardware. Not a knock off in most cases. More like “kinda” a knockoff situation on some out there. However, the gt2560 was never “open source” technically as they at the time did not release the schematic and layout for PCB. Like other open source boards. But I assume you have never pushed a heatbed to 300 watts or adjusted the pid loops on your own machine based on your answer of never having an issue with the MOSFET cooling as they are rated far above what they are used for if one incorporates Infinite cooling, which is near impossible. Your rate of heating depends on what MOSFET was Installed by any one of the manufacturer. And the firmware being used. The person designed it based on (The ramps 1.4 as the state in wiki page they link to from there site). I Skype with him here and there. Do a little more research dude and you will see what I mean. And if you also have provided personal Input of the newer version. Like adding back ing the open pins so that others can add things like a servo or Bluetooth or filament breakage sensor or a measurement sensor like I put and Incorporated in my own i3. Others stated that Joseph Prusa newest version say not open sourced in other comments below. But I stated he took open sourced ideas and improved on them and said if you look it’s actually there they just don’t make it easy. Have you seen toms latest video of when he interviewed Mr Prusa about the new quad color upgrade? You may want to listen to what he says there. I k ow this comes off wrong so my apologies now. I only am stating what I know and learned on my own and may be wrong as information does change from time to time anf is hard to stay up to date o “everything” at once. So have a good day/night dude.
The 24 volt is not really set up correctly. As it puts out 24 volt to everything instead of 12 for the fans. And is or can be finicky at times. 3d printed life is building another machine and has stopped using the gt2560 for that reason. The Rambo board can have up to three different voltage Inputs for the bed, extruder and stepper, etc. That’s the board by the way that is the actual generational improvement of that board, again, designed by ultimaker, who also designed the ramps and ultimaker board and a couple others that I just can’t remember at the moment. But yes, double the voltage and amperage is cut in half. Simple ohms law deal. All about the watts. Lol.
At least GT2560 is still readily available at a decent price.
youre right, I haven’t tampered with that simply because I’ve never had to. My printer has printed everything I’ve wanted it to with minimum issue for a sling as I’ve had it, so no. I do know what you mean, first thing I did when I got my RAMPS was compare all the important components to the official schematics.
I haven’t done any serious mods like Bluetooth or filament diameter sensors because I don’t have to ATM, though may add a filament end sensor at some point! Got it hooked up to Octoprint though, rather enjoyable, printing across the country.
Yeah, I agree with the Prusa team statement. Lulzbot do the same, they have a beautifully laid out website but the source files you really want are ambiguously hidden away.
I did see the video and I did listen! Though it was half-heartedly because I was also getting some work done.
Hahah don’t worry! Your demeanour is pretty cordial
