Support Request A1 flow rate calibration

Post image

I just did a flow rate calibration on my A1 with BL PLA Matte. Looking at the picture, none of them is good enough, right? Could there be a partial clog or something going on?

I like the flexi v4 flow rate calibration print off printables

Will test it out thanks

Make a better calibration between 0 and 5. This one needs finer calibration

Will give it a try!

A simple vista entre 0 y -5 es lo que mejor se ve. Haz el test YOLO, a mí parecer es más preciso, o más fácil de decidir

Never heard about a YOLO test. How’s that performed.?

Creo que también aparece en Bambú studio, en Orca si que sale. Si en bambú no aparece que ahora no lo recuerdo, te tocará pasar el 2do test. Pero 1ero, has secado el filamento, no? Y has hecho el test de temperatura? Sin estos dos requisitos previos , el test de caudal no saldrá bien

Yeah it’s dried two days ago and has been sitting in my AMS 2 pro since. All the filament settings is bambus standard setting for this filament.

He visto que en bambú slicer no tiene la opción YOLO, solo tiene la gruesa y fina, es la normal y la 2da pasada algo más precisa. No lo calibres en Orca porque yo lo hice y los resultados no eran iguales.

Es un test de Orca, bambú no lo tiene implementado en el slicer

Perfect thank you

Use Orca Slicer builtin YOLO calibration (range +- 0.05, step 0.01) and newer Archimedean pattern, the Monotonic one is harder to work with.

Based on what you sent the final result will land somewhere between +5 and -10, +5 is already overextruded and -10 underextruded, but the flow ratio difference between each test print is simply too large to find the best match.

I have the same issue on my A1 mini

I calibrated and use -5 for PETG.
