[Grbl_Esp32 Issue#196] Made a nonworking pcb About GRBL HAL

Issue #196 | 状态: 已关闭 | 作者: mac7988 | 创建时间: 2019-08-23

I made a pcb using some tips on buildlog and can’t seem to get it to work. I am connected via bluetooth. I am only trying to job X axis with no result. MPOS changes but no cigar.
I tried another board (uno) to verify my stepper driver was not fault but that seems to work just fine.

Confused on what I am doing wrong. Is there a configuration that needs to be entered?

Can someone point me in the right direction. I been trying to figure out what is wrong for 2 days.( I am also dumb)=(.

@mac7988 Pololu says: If you are connecting more than 20 V or your power leads or supply has high inductance, we recommend soldering a 33 μF or larger electrolytic capacitor close to the regulator between VIN and GND. The capacitor should be rated for at least 50 V.

No capacitors shown in your PCB.

Thank you Misan for a quick response.currently I have a 9v power supply hooked up instead of 24v.

I get no movement at all from my stepper motor.
I even tried a new stepper drive and a new esp32.

I am puzzled

mac7988 I cannot know what type of wiring you did. Is it explained anywhere
else? I presume you get the USB/Web/BT working and answering properly but
again I do not really know that.

When you have a problem and need help, first let us know all details about
your setup so maybe we can help.

I figured it out! Turns out I had my transistor wired wrong. Fixed and working
