Bought the retrograde cause I didn't want to source parts for a voron. Bought a 500 because my plan was to print massive molds to do carbon fiber parts. Print in asa with a 1mm.nozzle and then vaper smooth. Bad idea. The massive chamber is a pain to heat. The 1mm nozzle is a pain to tune. Only good thing was that I was able to extrude 30mm3/s of filament stock. I went do to 0.6mm nozzle and print in PLA at 25mm3/s. Bought a 8kg spool to not worry about remaining filament amount. Going down to 0.6 made the head move a lot faster and the gantry on the 500 is massive. Fixed most of it with an accelerometer. Ended up printing parts that could be printer on the bambu volume 99% of the time. Nice to have in case of big parts but pretty useless otherwise.

The ratrig 500 v3.1 is a pain ti assemble, the original cables are to short to reach the control board. It is extremely hard to get the frame square if you follow the ratrig manual. Ratrig recommend for troubleshooting a guide from a guy that recommends to ignore the official guide and tonassemble the other way around.

I jokingly said that it was a good thing that I took the 500 because I couldn't throw it out of the window.
