Geeetech

More testing and trying, I feel like single Z Axis Motor is one of the reasons 3D Touch fails intermittently on this design printer, because of the Rocking tolerance in this A20M, sometimes it nails it, sometimes it fails, about 50/50

Can Geetech make an Upgrade to Dual Z Axis ?
i.e
Like this one ...

1, This thread is not specific to the A20M and is in the wrong place (I want to discuss the A20 Series here)
2, Jfkerekes !! I had more luck when I moved the Z Sensor lower where it won't fight with the 3D Touch,
3, I had the Most Luck without the 3D Touch and Manually leveling the Bed

The Sensor ...

The Problem with using a 3D printed Part as the Fan cover on this A20M

Is it just Melts

Ok that was certainly part of my Big Issues, what I did do to mess things up was use the Current version of ArdwinoIDE to load firmware
(Because when you order 3d Touch the thing does not shop from factory without the 3D Touch Firmware, so you got to mess around for weeks figuring it out
Indeed ...

Into my Third week of utter frustration with this printer, I am learning, though getting really close to heave it out the window
I just noticed this note
You need to upload the firmware via Arduino IDE 1.8.5(Use the 1.8.7 or higher version may cause the motor work abnormal)
Yeah I did use 1.8.7 ...

Everything started working after ArdwinoIDE released a new version, from there Marlin would compile without errors and I was then able to sent up the Marlin changes for 3D Touch and to reduce the Baud rate to Windows Max 115200
From there (As the Geeetech Software doesn't yet support or work with ...

Though I have this on Windows 7, what I had to do was use the Ardwino IDE to edit the Baud Rate in the Firmware down to 115200 (The Max windows seems to support) so I'm talking about the Marlin firmware, editing the configuration.h file ...

Ok, Miracles happen, once I used the new release Arduino 1.8.7 then Marlin firmware for A20M with 3D Touch compiled AND uploaded, AND my 3D touch appears in the menu, Great
In the Front Panel, Auto Leveling goes on, though how to Calibrate? as it seems to level at about 5mm off the deck, so I ...

What did he say?

Geeetech Can I pay for Techncal Help on this?
What I need is for the Easyprint3D to include support for the A20M, I do guess this will happen eventually, I guess the product is a little premature
Most every person who gets a A20M product will be looking for this
