When I auto home my printer my nozzle will ram the bed and the light won’t turn off, when a put the plate directly under the probe above the nozzle it’ll detect it, hi have tried, a new probe, lowering there probe, and z offset changing, what can I do to fix this ---

I would check the wiring as it connects to the mainboard. I fitted the 3D Touch to my SV02 and initially the printer wouldn’t turn on. I rechecked the pins on the board and found the instructions I followed had the pinouts wrong and I had shorted the 5V rail. Once this was sorted I had the same issue as you are experiencing with the nozzle trying to get through the bed. I had put the trigger wire on the wrong pin so the mainboard wasn’t seeing the probe had triggered. ---

I tried putting the plate up to it while homing and it worked but it seems the range of the probe has gone down, is the plate screwed up or should I not use the sensor they provide ---

It sounds like you need to reset the Z-Offset. Do all the leveling again, like when you 1st got it. ---

[SV06 Plus Wiki](https://wiki.sovol3d.com/en/SV06PLUS) Download links at top of page. Try to set the probe back where it was before you start. ---

I’m sorry but I don’t understand how this fixes the probe not detecting the bed I mean it does but not before the nozzle drying into the bed ---

You posted above that you didn’t do the setup when you got the printer. You need to put the probe as close as you can to where it was & follow the leveling guide. ---

Oh… yeah it won’t let me get to the leveling menu cause it rams into the bed when it auto homes the z axis automatically, I don’t know what prompted the problem but it’s all kinda sudden cause it was fine one day finicky the next and broken the next ---

Could it be the bed? Did the bed somehow lose magnetism or soemthing ---

Never heard of that happening. If the plate sticks to the bed, it’s magnetized. You have the bed, then a rubber magnetic sheet, then the steel print plate. ---

Can you post some pics like the user did. > [@Auto Home crashes into bed](https://forum.sovol3d.com/t/auto-home-crashes-into-bed/4909): > > Hello, Had to buy a new sensor and after I’ve installed the new one I can’t get the printer to work right. Whenever I try to calibrate it, it has to do an auto home first and it always crashes into the bed so I have to power it off. The sensors red light is on, it is mounted correctly and at the correct height. I flashed the firmware and I reset the eeprom several times. I’ve had the problem before and fixed it but that was a while ago and I can’t recall exactly what I did. Post them here in this thread, so things don’t get confused.
