It worked!!! Thanks for the support!!!by ferdaze - Controllers
Because of logic level of Raspberry PI is 3.3v, the RESET pin is also inverted so you can't use it with a standard AVR programmer that expects nRESET. The only thing I'm wondering is 5v vs 3.3v on the UNO source pin.by ferdaze - Controllers
I think this is how the connections go. What do you think?by ferdaze - Controllers
I'm not sure which pins to use on the Einsy board. It only has a ICSP 32u2 connector so need to find the correct pins elsewhere. Anyone know?by ferdaze - Controllers
Looks like that's it. When I verify it with Arduino it shows "Sketch uses 248452 bytes (96%) of program storage space. Maximum is 258048 bytes.". Thank you sooo much!!! So now I need to update to the bootloader to use Prusa. Any good guides on doing that using an UNO?by ferdaze - Controllers
I built a clone of a Prusa MK3 and bought 2 Einsy Rambo from Ultimachine but when I try to load Prusa firmware to them I always receive errors. The errors happen on both new Einsy boards. I have tried Windows and OSX. Downloaded file many different times on many different computers same result. I have downloaded source of the 3.2.1 and also get the same result. I can load Marlin 1.1.8 and 2.0.x wby ferdaze - Controllers
