I’m trying to z-probe but when I give a G30 command the Z motors lockup, and make a terrible loud buzzing sound. I then have to hit the kill switch. The Z value also goes to -400 when this happens.

This one is easy : you are trying to probe too fast.
Reduce your probing speeds and it’ll work fine.
Also note you want to read the documentation before asking questions : http://smoothieware.org/troubleshooting#my-stepper-motor-does-not-turn-at-all-and-makes-a-very-high-pitched-sound
Yes, this is not the problem I have set low a very low Z probe speed and there is no change. Additionally the Z axis works fine when homing and moving under normal commands.
Can I see your config ? What command do you send exactly to ask it to probe ?
I use G30 or G29 commands to probe, here is my current config but I have tried many other settings trying to fix this

Also uncomment z_acceleration
Still no change, G0 and jogging still work fine, g30 fails. Putting a metal object underneath the induction sensor changed the pitch of the noise and eventually returned a Z offset value
This is a very strange one, first time I see a problem like this.
Would you mind :
- Saving your config file
- Formatting the sd card
- Pasting to the card the very latest example config file and firmware
- Only modify strictly what is required to test G30 : steps per millimeters and zprobe module, nothing else
- Test
OK, I re-downloaded the firmware (apr7build), the example config file, I replaced the pin assignments, set the step/mm, and turned on the network interface. I issued a G30, same thing happens. I tried pulling the probe and max z jumper, still no difference. I enabled the gamma endstop pin, homing works, G30 still does the same thing.
It’s been some days, is there a solution or should I just move on?
Did you actually format the SD card ? Can you try another sd card ? This is really odd behavior it’s like it’s not taking your config into account.
Yes, I actually formatted the card after zeroing all the data, a process that took a long time. There is no change.
Before you ask I took the step of completely redoing every step. That means from a completely blank media, uploading the firmware and completely new example config, minus changes to get the z probe to work. Again the printer moved on it’s axis using manual controls completely fine and only when a g30 command was given responded with the loud lockup noises.
Can you move the Z axis at all after power up? Your config has dual extruders set up, and a gamma driver current setting of 1.0.
The Prusa i3 is a dual Z motor machine, and you’re only putting 500ma into each motor. I had this problem with my Z motors sucking too much power and ended up splitting them up onto separate drivers. Crank up you gamma current to 1.8 and try again.
My Z axis works fine. Again, the only place it has any problems is when running the probing Gcodes.
Is there a fix to this? Please let me know, otherwise I’m just going to have to switch back to Marlin and sell my board. Having Z probing working is important to me and was working perfectly fine before moving to smoothie.
Well it’s working fine for everyone else, so we need to figure out what’s wrong with your setup, but the last person to suggest something, you dismissed them …
Please try cranking up the current on your Z axis, it’s probably not going to fix things but we might learn something useful in the process.
Also can you try doing G30 F20 instead of G30 ?
I am also getting a load buzzing noise when G32 goes run and get -173 in axis axis etc
still will look into this and try and get more specific info for you.
