Geeetech

Hi,

I have install the new firmware A20T_G05_V1.1.8-2.1-3DTOUCH.hex on my A20T. I have follow the steps provide by Geeetech by video.
Unfortunately I'm facing a lot of issue to setup the 3DTouch.

1) During the callibration of the auto-home, the Z-axis will beat against the bed and tries to force 2-3 times.
2) After that If I do a Bed Levelling then The Z Axis beat the Bed.
3) If I re-do an Auto-Home then the Z Axis go only up.

What is wrong. I have to much issue with this printer. I solve it one by one, but every times a new one occurs.
Also the download of the firmware is very hard to process.

Best bregards,

Hi，you can enter the following suggestions in Repetier Host and send them to test one by one:
M280 P0 S10; push the pin down
M280 P0 S90; pull pin
M280 P0 S120; self-test – continue until you pin up / down or release alarm
M280 P0 S160; release alarm

Modify the z offset of 3d touch,
Whether to remove the limit switch of the z-axis
