Beta test of GCode Simulator v0.99 for Android started !
The new version adds a printer control panel which can control a 3D printer (Sprinter,Marlin,…) using a USB OTG cable.
It does not support printing yet (next step)

Google offers a new feature for the Play Store to run new Apps through a closed beta test. The beta test is restricted to members of this community (3D Printing) . If you are interested in trying GCode Simulator v0.99 Beta just follow the link below. I tested with Samsung Galaxy Tab 2 only, feedback is highly welcome.

Says it is not compatible with my nexus 4. I will try it out on my nexus 7.

3

installing on my 1st gen xoom!

4

Ooh, I have a Tab 2 …
Damn, it is under my wife’s ID.

5

Hmm says it is incompatible with all of my devices. oh well.

Can’t wait for the printer control. I’m sure I can pick up a used Android for less than a good LCD panel, and it’s already got wifi, a good processor, touch screen, etc. After being able to control a printer, if you could work on fitting the UI onto a phone screen that would be perfect – I’ll just have to find a device that has USB-OTG capability built into a ROM. (My SGS Vibrant supports USB-OTG with a kernel driver, but you have to splice in 5v)

@ThantiK I agree, a cheap Android device with print support has many benefits over a LCD.

8

HTC One supports USB-OTG but rejects my reprap with “Unsupported Device” :frowning: . Will try my old Nexus S next.

9

on my xoom it recognizes the otg device but it wont connect.

is there any way to get a debug info?

10

@Nicolas_Arias there are some usb debug apps in the play store. “USB Host Controller” and “USB Host Diagnostics” helped me. Gcode Simulator will connect to the first USB device with 115200 Baud. Does it show “USB Device found…”?

11

USB OTG does not work on my Nexus S. Tried with custom kernels and y-kabel but no success.

12

@Mathias_Dietz , that should really be settable. 250000 baud is becoming more common. Or maybe have it attempt both?

13

@Nicolas_Arias @ThantiK
try the new version V1.02. A long click on the connect button will toggle the Baud rate (115200 vs 250000)

14

@Shawn_Moore
did the nexus 7 work ?

15

@Mathias_Dietz , just updated - I’ll connect to my printer in the morning. 5am almost here.

16

@Mathias_Dietz installed and runs. Haven’t done much with it yet.

17

It will not download directly to the tablet I am wanting to use (listed as an incompatible device) but what I’ve done is side-loaded the apk. First I downloaded to my DroidMaxx from Google Play store, and then used APK manager to export the apk to the phone SD card. Mount phone SDCard in windows, transfer apk to a fresh microSD card, insert microSD card into cheap chinese android tablet and install… viola! GCode simulator is working on what google play store claims is an unsupported device.

18

@Steve_Graber this version requires the android.hardware.usb.host capability which your device probably does not support. I guess you will not be able to USB connect to your printer without the capability.

19

@Mathias_Dietz You’re absolutely right. Even though this tablet comes with a supposed OTG support and full-size USB ports, they are not recognized by USB Host Diagnostics or your software. I think I will need to find a list of inexpensive tablets that include hardware.usb.host capability. :slight_smile:
