[SOLVED] Bad arg letter.... on 12864 display with Maestro board

Bikerbuz

Just tried yet another menu, but I get the same result. "Bad arg letter" on the first line thats not commented out.
I'm getting more and more convinced that my printer is possessed by evil goblins.
Or maybe the display only understands mandarin and the only line in english it knows is Bad arg letter

Well, you maybe right about your Maestro being haunted. I just loaded your files onto my board and the menu works fine. I wasn't expecting to see .g files in the menu directory instead of the macro directory but it all works. The only obvious difference is that I'm using firmware 2.03beta2 where you are on 2.02a. Maybe try to update the firmware. I did notice that the 2.03beta2 has a specific firmware file for the Maestro and that is the one I used.

Ok, Thanks for the tip and for trying the menu out.. I'll try that tomorrow. I just shut everything down and I'm just about to make me some dinner and then it's netflix and chill for the rest of the night.

My Maestro-powered printer is busy right now, but I'll try your menu file when it's finished its current job.

Thanks. I'm sure it's going to work perfectly on Your Maestro just as it did on DaveA's though.
I'm almost certain that it's something wrong with my wiring or the Maestro itself. I just can't figure out how it can miss read the files and then respond with clear and readable text if the wiring is to blame, but I'll re check all that tomorrow. For now it's a printer free night for me

Yes it works perfectly on my Maestro.

Please check that you really are running firmware 2.02. You can do that by sending command M115 from DWC or over USB.

Well, I downloaded ver. 2.02a from here and installed it Without any errors. It had ver 1.something before and It now reports ver '2.0(RTOS) (2018-06-05b3' from the software information tab on the settings page. With M115 in DWC I get this:
FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 2.0(RTOS) ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2018-06-05b3
Do You mean that it could somehow be another version? Should I try installing the latest beta?

@bikerbuz You're still not running 2.02.

Download this zip file https://github.com/dc42/RepRapFirmware/releases/download/2.02/Duet2Firmware-2.02a.zip
Upload the whole zip file through the DWC and everything should get updated properly. Use M115 again to check.

Ok, Thanks. I had already gone to bed when You posted and I'm at work now, but I'll do that when I get home tonight.
I reeeally hope that will fix it This time difference is a bitch...

Bikerbuz

@Phaedrux
Downloaded the file here at work and thats the exact same file that I already installed, so I guess I did something wrong (go figure) when I installed it. I'll let You know how it goes tonight

dc42

It might be that the version of Duet Web Control you were running initially didn't handle the case of a main firmware file being included in a zip file. If so then it might work second time.

@dc42

Ahh, ok. I hope that's the issue. I've already done a couple of tests and it prints great.
If the display starts working, that's the last "hurdle" in my rebuild of the Mecreator2. For now that is.

The next step is to make the extruder all metal, so I can increase the temp and hopefully print nylon.
Maybe even PC at some point as I have a couple of rolls of that stuff.
If that works, I might try out a bowden setup so it can use all of the bed surface. Now it doesn't quite reach the front edge, due to the bulky extruder setup. An extra 5-10mm would be great for printing RC car bodies... I'll let You know tonight if things worked out

A big thanks to all of You for Your help and Your patience. It's greatly appreciated.
It's a bummer that I can't return the favor. At least not any time soon...
I'm officially retracting my claim in my first ever post on here, that I thought I understood the basics of how the Duet boards work.
That's clearly not the case, but I hoping to slowly learn as I go along in this endeavor.
