Why not update FW for M2 printers?

Post by bratan » Sun Oct 07, 2018 1:44 am

I love MakerGear and printers, but you guys dropped the ball on Firmware updates for M2.

Problem 1.

Firmware doesn't work with latest Arduino IDE and version 1.5.5 needed. The "fix" for this can be implemented in less than 15 minutes by replacing variable types. I've done it and was able to update FW using Arduino 1.8.x, why can't you release this easy fix?

Problem 2.

I recently upgraded Rev D printer to V4 hotend. Because mine uses older "silver" stepper I had to use really old version of Marlin FW that doesn't even support FAN AUTO OFF feature... Is there something special in REV E firmware? Nope! Just needed to change few lines of code to get it working with reverse endstop switch and different Z stepper. Works like a charm.

Please please, update Firmware on your site, I can send you my modified version if it helps :)

Mainly it's just a support headache for MakerGear. I am an open source software developer, so I know this routine very well: When you're dependent on someone else's software, they can change it at any time and break all your code. It's a fact of life in open source development. That doesn't mean it isn't a royal pain.

So your "Problem 1" looks like a fairly major update for Arduino with the (unfortunately very typical) backwards incompatibility, and really does need to be brought to the attention of MakerGear, as it affects all existing users.

Your "Problem 2" involves those with old but upgraded printers: A vanishingly small portion of MakerGear's customer base. Not to mention that most (all?) of the people who own a MakerGear printer from that far back and are willing to upgrade it are probably, like you, technically fluent enough to figure out how to configure the most recent Marlin code to work with the M2. Your best bet is probably to make your own fork of the Marlin code on github (from https://github.com/MarlinFirmware/Marlin) and then post a link to it on the forum.

I have just recently upgraded a *very* early version of the M2 to the latest 1.x Marlin release with BLTouchSupport. The only outstanding issue is false thermal runaway errors on the bed heater. I've currently got thermal protection for the bed heater disabled, but plan to work on getting a real fix when I get time.

If there is interest I can fork Marlin and put it up on my github.
