What are the default settings for velocity, accel & push\_length in your buffer\_stepper.cfg file?

Just found the post which mentions the settings I used.

I put accel back to its default setting of 5000, & the filament fed fine from that point on. I now have velocity set to 30, rather than its default of 150. Doesn’t seem to have any adverse effect with regard to buffering/feeding, but it does make a notable difference to the noise level.
