Ok, make that update 78. Apparently I didn’t update the exported JAR files in the github project.
You should be able to run the files in last_official_release and see the new features.

Thanks to deanville for noticing the oversight!

Two steps forward, one backward…

The update 78 jar does now show all the new conversion modes and appears to generate ngc just fine. However, with update 78 I have lost communication with the arduino, no pen movement, no jog, no “>” replies.

If I drop back to the environment in the download on the Makelangelo 3 product page, I do get pen and motor movement.

The arduino firmware is the same between environments (according to a hex diff). I’m starting the jars with their appropriate batch files. I did note that when starting update 78 I see the cmd window reporting a “WARNING: Could not open/create prefs root node SoftwareJavSoftPrefs at root 0x800000002. Windows RegCreateKeyEx(…) returned error code 5.”

Also, a “check for updates” with update 78 running yields a message that an update (4?) is available.

Can I run any tests to narrow this down?

Some progress. The warning in the cmd window goes away if you create a “Prefs” key under “ComputerHKEY_LOCAL_MACHINESOFTWAREJavaSoft” with regedit. No idea why it wasn’t there, did a completely clean uninstall and install of the jre two days ago.

However there is still no pen control or motor jog here with update 78. All works a treat with the version available via the product page.

Will continue digging around.

Are you using the AMS version? I have done most of my testing on the RUMBA firmware.

Edited to correct date/time.

I was using the firmware_asm1 as contained in the makelangelo-master.zip downloaded on 09/30/14 at 3:54 PM Eastern. Looking closely at that zip there is a last_official_releaseWindowsfirmware_asm1 directory containing firmware_asm1. In that same zip is a tree arduinofirmware_ams containing a firmware_asm. I just grabbed the firmware under the windows tree and ran.

I have downloaded (10/02/14 8:32 PM Eastern) the master zip again from github again and find that there is a firmware_asm (not firmware_asm1!) in the windows directory tree.

I’ll upload the asm firmware to the arduino and test again.

Did the master.zip change after I downloaded the first time? Or did I somehow cross-contaminate it (although the extracted time stamps are consistent for all content, puzzling).

OK! Progress. After dropping the library directories from last_official_release into my Arduino library and editing firmware_asm to define my AdaFruit motor shield #1 in and swap motor 1 and 2, then uploading I have a working drawbot again! I’m still stumped by the existence of firmware_asm1 in the first master.zip download.

Should I be seeing a “>” heartbeat every second though?

Thanks for the help Dan!

seeing a regular > is part of a plan to help the PC software detect when the arduino has disconnected silently.

It’s pretty rare, but it happens. In that case I’d like the software to say “hey, we disconnected. Reconnect to the robot, tell it where we left off (assumes that the robot finished the last move command it was given) and then continue from there.”

But this is an edge case that happens very rarely and I won’t personally be writing it any time soon. I leave this as an exercise to a young Java programmer that wants to contribute to a well known open source project.

Ah, I asked a very ambiguous question.

What I should have said is “I noticed in another thread that there is a “>” heartbeat every second in the terminal panel. Should I be seeing the heartbeat with update 78, because I do not see it.”

I hope that is a little clearer.

we’re currently up to #80. the RUMBA version should show it. the ams version might not.
