Hi
My new printer dose not home to front and left side
It gos to front center?
When I manually move it with the control panel nob it only gos to about the center of the build plate
Also looking for x y and z end stop calibration help
And Bed leveling help

First thing I will ask is, did you inspect the printer mechanically? With the printer switched off does the print head move freely from front to back and side to side?

If mechanically the printer is fine and you have no spots where the print head is being mechanically restricted, then that leaves us with firmware.

Why firmware because the printers XYZ limits or some refer them as print bed limits etc are defined in the firmware.

There are some sketchy workarounds but the best and only way is to configure proper bed offsets in firmware and configure your slicer with actual bed printable area.

But this is the biggest problem and that is that editing the firmware and compiling is not for the faint hearted.

Question is why did this happen? Did you flash any firmware yourself? Any mechanical changes to the 3d printer?

By the way did you buy it new or used from someone else? Just trying to make sure you actually know all the history of the printer.

Did you try downloading the official firmware from the Creality google drive: https://drive.google.com/drive/folders/1...YVLFXKBFBi

There are 2 versions of the firmware there, depending on whether you have a BLTouch installed or not. I assume not since you were talking about bed leveling help

Usually the process is simple, copy the firmware file onto and SD card, insert SD card into the SD card slot on the printer, switch on the printer and the firmware update should be done, power-cycle the printer and test to see if everything is functional.

XYZ end stops? You mean the physical ones? Just un-tighten the screws using a hex key, move to desired position and tighten them back. Not much too it as long as they does hit the physical limits of the machine. The Z limit is more important as this will limit how much you can adjust the leveling on the bed.

Leveling the bed? Tons of videos out there. But what exactly is it you would like to know?

New printer from Sainsmart , xy and z all move freely ,no fw flashing yet
I found I knocked the x micro switch and broke it putting it together
if I start the extruded at the far left side It will home
I guess not having the limit switch is making it not home correctly

Under the heat bed one of the springs is lammed up under the pad we're the wires Connect to it
There's a plastic guide that the spring sits on top of or under?how is that supposed to be ?
So 3 springs look consistently the same and that one spring is jammed up and compressed more
Yes there are too many Bed leveling videos and techniques
I ordered a new switch and I'll look into firmware
Thank you for your response!
looks like my fw is 1.0.4
your link shows fw 1.0.2

Yes the limit switch is important for the printer to reset its home reference which is why its not homing correctly and the nozzle doesn’t not travel across the entire print bed when you move along the axis via manual control.

Can you show a photo of that particular bed corner where you mention excessive compression of the spring?

Too many videos on youtube but just pick one Ender series by someone whose format you like and follow it.

The link I gave you is from Creality’s official google drive. Sainsmart may have compiled some custom firmware for reasons unknown to me.

I can take a picture but
I took it apart and reset it
Going to put the replacement switch on and then play with it before I update the firmware
Also got spring upgrades coming
Thanks again
