MakerGear Forum

Just got a used MakerGear Prusa and need help with firmware?

After dusting the entire unit I regrettably started by updating the code on the Arduino. Edit: Short version, I need to re-do firmware.


So my questions are...

What Firmware is recommended?

Do I need to Modify the firmware?

How do I check if there were any recalls on my unit? As a 2nd owner, I understand if I need to pay for the recall service, I just don't want a fire in the house.

I know nothing about the Prusa models, but MakerGear does have a Wiki page for it here:

Hope that helps.

I followed the steps on the Google doc linked on that page (https://docs.google.com/document/pub?id ... zywzu3k4w1) But it is out of date and their definitions for Configuration.h don't match up to existing definitions very well. For example there is no more "#define THERMISTORBED 1". I'm guessing that is now called "#define TEMP_SENSOR_BED" so I set it to 1. It is still wrong somehow because I still can't get Pronterface to get a bed temp reading.

Try the old stock Sprinter firmware from MakerGear: http://makergear.wikidot.com/firmware

You can certainly try to work up a recent Marlin version, but that will require going through Configuration.h and Configuration_adv.h line by line and applying the correct settings, either from the doc or from the Sprinter settings.

Thanks, that is just what I was looking for, I hope that one works for my Prusa (with RAMPS 1.2). I'm now seeing the matrix of possibilities and wondering if I should save myself a week of headache and upgrade to the latest RAMPS?

The latest RAMPS is like $15 from China, so you might as well.

The old stock firmware JSC shared plus a lot of configuration tweaking was needed to get it up and moving. The wiki for my model has a few errors I have found, but hell, it made me work for it.


I'm now stuck on a new place. The y stop is good, but the X and Z stop are in the opposite direction from where the software thinks it should be. I can easily move the z-stop from under to above depending on whats better for a Prusa Mendel, but the x stop is pretty set in stone right now. How do I invert it?

I just inverted the entire x and turned the whole printer around....solved.
