Testing with a bigger knob on the A10[edit]

Geeetech Sensor[edit]

see facebook post The following Sensor works on a Geeetech A10: https://www.amazon.de/gp/product/B07M5JHKYP

BLTouch[edit]

I had the Geeetech Sensor in operation for a while but it did not work as satisfactory as hoped. I am trying the "original" BL Touch now see http://www.BLTouch.com

Firmware 1.1.9 with BLTouch[edit]

• http://www.geeetech.com/forum/viewtopic.php?t=61959

has a link to:

• Marlin-1.1.9_A10_with bltouch.zip

that i used as a Basis. Please check the BLTOUCH_DELAY in Configuration.h which i have seen with other values in other bltouch firmwares

/**
 * The BLTouch probe uses a Hall effect sensor and emulates a servo.
 */
#define BLTOUCH
#if ENABLED(BLTOUCH)
  #define BLTOUCH_DELAY 375   // (ms) Enable and increase if needed
#endif

I compiled and uploaded things with Arduino 1.8.9 on a Mac

Configuration[edit]

I ended up with a Z-Level offset of -2.28. I tried -2.4 and did a 0.15 mm DIN A4 paper test moving the Z-Axis down and still having 0.1 mm to go - the paper was a bit thight so i went for 0.02 less. With Octoprints Bed Visualizer plugin i got: which i consider decent. The print results are o.k.

Installation[edit]

I had to follow both of the following videos to get the Sensor working:

The firmware outlined in the first video is available from

• Geeetech's github site

Alternatives are the links below and see my own installation above.

• https://github.com/jakobend/Marlin-A10
• https://drucktipps3d.de/forum/topic/mein-geeetech-a10-neue-revesion-und-ich/?part=2

see videos and Marlin on how to compile and flash the firmware onto the device.
