• Yep, I know about the RX connected to TX thing. I tried the same procedure I did before (i.e. just changing the BLUETOOTH_SERIAL and BLUETOOTH_BAUD) values using the v0.92 firmware and it worked! I was able to connect and control the Arduino through…

  in Communicate with RUMBA board via alternate TX/RX connections? Comment by k_eckes January 2017
• So, I modified the firmware to use Bluetooth (#define BLUETOOTH_SERIAL 3, #define BLUETOOTH_BAUD), compiled, and uploaded the firmware to the test Arduino Mega board via USB.  When I tried to connect via the TX3/RX3 pins, I wasn't able to open a con…

• OK. With the new version I was able to compile it using Arduino 1.6.12. Didn't try on v1.8.1. NOTE: the new version would not compile unless the HAVE_HEATED_BED parameter was true ('1'). When it was false ('0'), the compiler threw the following erro…

• Downgraded to v1.6.12 and I receive the same error. I'm wondering if my libraries are updated to newer versions and that's the reason for the error.

• Thanks for that, I'll try an older version. Before trying with v1.8.1 I had tried with v1.6.4 and it also did not compile. Guess there's a sweet spot!

• Great, thanks for the tip. I didn't realize the E position register was shared for multiple extruders. Regarding the firmware, I tried to update to the dev version but it won't compile on Arduino 1.8.1. I'll go ahead and start a new thread about tha…

• Just to be sure, I ran the same script using Repetier-Host in Linux and got the same result as on the Mac. Thus, I'm more confident this is a firmware issue.

• OK, tested it again. I am not able to move the x or y axis while the long extrusion is running. Actually it does seem like a firmware hang or connection timeout, sorry for giving the opposite information before. I can also confirm that in manual mod…

• I set the max extrusion length to 700mm. The reason is because I'm not actually using an extruder, I'm just using the extruder pins and gcode commands to control a stepper motors for a different purpose. I was running E1 very slowly (gcode speed F50…

• I am having a similar problem. E0 works exactly as expected, both in manual mode and while running a gcode script. E1 mostly works as expected in manual mode (i.e. when I change to extruder 2 using the T1 command and then send a single G1 Fxxx Exx c…
