''Only use this method if you are experiencing all the known issues below.'' |
|||
Reboot the machine or try setting an arbitrary Z zero and reset things. |
|||
'''Known Issues''' |
|||
* The Touch Top and Measure Tool feature works without errors |
|||
* Before loading any G-Code, the Z Soft Limit is exceeded without the tool being close to the Spoilboard |
|||
'''Resolution''' |
|||
* Attach a tool to the spindle |
|||
:* Any tool will work, but using the standard 1/4” flat end is ideal |
|||
* Turn off all soft limits with G-code L21 |
|||
:* This allows the ability to jog the Z past the Z bottom soft limit |
|||
* [https://youtu.be/zhRtr7aMlVw Jog the bottom of the bit down to the spoil board] |
|||
:* Jog the bit bout 1 inch over the spoil board |
|||
:* Switch the speed to move by 0.1 steps (not using fast, medium, or slow) |
|||
:* Jog the bit to about 1/4 inch from the spoil board, then switch the speed to move by 0.01 steps |
|||
:* Use printer paper under the bit and move it back and forth |
|||
::* Lowering the Z until the bit snags the paper |
|||
:* Jog the Z axis up by 0.01 steps to leave it the width of the paper away from the bed |
|||
* [https://youtu.be/r9-QHmy459o Click the calibrate button] |
|||
:* The command log will first asks you to jog the bit to the bed, which is already completed |
|||
:* This step will start the process to reset the Z bottom soft limit at the current position of the bottom of the bit |
|||
* Press enter then the command log will say it will now use the Measure Tool feature and to ensure it can move freely |
|||
:* This step will take into account the length of whichever tool used |
|||
* Press enter and the machine will move up to the world Z0 (the Z top hard limit), then move to the built in touch plate to measure the tool |
|||
:* The machine, in theory, knows the location of the collar and the Measure Tool allows the machine to figure out where the Z bottom soft limit is, relative to the world Z0 |
|||
* After the Measure Tool operation is completed, the Z bottom soft limit has been set |
|||
* Test if the calibration has worked |
|||
:* Click the Park button to move the spindle to the world XYZ 0 |
|||
::* This should be off the edge of the spoil board |
|||
:* Jog the bit downwards towards the bed |
|||
This should trip the Z bottom soft limit when the bottom of bit is just above the spoil board |
