Thank You,

I tried this on bread board it works. but during raspberry boot motor get some steps, motor rotate but skipping steps and making noise. simply motor rotate but not properly. i sat steeper current by set screw of A4988.

i am making printer with just HDMI lcd, no UV so i skipped that. and i want simple circuit so i skipped i2c, led and stop ray also. is this affects?
and also advice resin for just LCD printer?

I changed by paint

Thank You.
