Issue on Printrbot Smalls. I flashed it with wrong firmware.

Postby taronagano » 2018-Nov-Sat-13-Nov

My Printrbot Smalls has an issue.

I am a beginner of 3D printing and that is my first 3D printer.

I flashed the firmware of printer board with wrong one that is for Printrbot Play.
Then, my printer became not working correctly.
When I order to print by using Cura, the hot end moves in the air, it can't recognize proper distance to print bed.

I need anyone's advice how can I fix the issue.

Let me tell the story why it happened.

I built up the kit about three weeks ago and enjoyed 3D printing for a while.
For small objects, the printing quality seemed OK for me.
But, I found an issue when I was printing large size object that had large footprint.
The first layer wasn't print well.It wasn't even because the hot end nozzle touches print bed when the arm reached at some point along Y-axis.
I did G-code M212 to adjust Z-height, but I couldn't fix the issue.

While googling solution, I found a site explaining how to flash firmware.
Then, I decided to flash it.
After re-flashing the firmware, I tried to print and I found the things became worse.
The hot end moves in the air, it can't recognize proper distance to print bed.
I realized the firmware that I downloaded wasn't correct.
I think the firmware works only for Play instead of universal.
I didn't know each Printrbot uses different firmware even they use same version of Printrboad.

Since then, I was searching the firmware for Smalls.
But I haven't found it.Printrbot website that the firmware had been uploaded was already closed because of their out of business.

Now, I am thinking to flash it to Marlin firmware and tune it for Smalls by Arduino.
But, I feel like it difficult for me. I don’t know about programming.

Are there any way to fix my Smalls? I hope somebody give me an advice. :)

You may be able to find a suitable hex file here: https://github.com/Printrbot/Marlin/releases
Also, there are instructions that I wrote some time ago in the Wiki. Many things have changed, but the overall description and flow is still valid. Click on the red-beige-white "Printrbot Wiki" icon next to the "Search..." box, and then select Firmware Update.

Hi RetireeJay,
Thanks for your advice.
I try the firmware that you linked.
Also, I check the instruction of Firmware Update that you wrote.
