Z-20 slider and homing

Original/PRO Series (Buildbotics) (Gen 1) Troubleshooting (X35/X50)
1

I installed a new Z-20 slider with a air cooled spindle. Everything was fine when first installed. I did have to upgrade the BB firmware to the latest to include the EM60

After setting for a while I fired up the machine today and z-axis homing just vibrates away. I had to e-stop the machine and look up how to fix this issue. I have the stall amps set at 4 to get it to work but it sounds terrible. Is this normal? Is it safe to leave the setting at 4 from the factory setting of 1.

Ran a sample run and it worked well but wanted to make sure I am not going to damage anything.

PS>. downgraded the firmware to 1.2 (latest gold code) and had the same issue. Back up to latest beta for BB.

Thanks!

Well…wink,wink…it helps to LISTEN to the video. DECREASED the amperage rather than increased and all is well.

Whew!

Thanks everyone!

Hey st,

it’s just like with eggs. You can boil them, and boil them, and boil them, they don’t get soft! :slight_smile:
