Hello again! I’m back with the PrintrBot Metal Plus, I’m back with good news and bad news. So let me start out with the bad news..
some backstory of why this sucks.. I work a full time job, 8-5 and have weekends off which i really look forward to. Saturday and Sunday are my main printing days and unfortunately for me I woke up Saturday June excited to start printing and to my surprise… My printer would not connect to my computer, I felt that the power supply failed and fried the board. I’m not entirely sure yet but that’s what I was guessing. Here is a video I sent to Printrbot in hopes of identifying the issue and to give me an explanation.. Exactly what is going on before I dissect. This has me as really quite disapointed. I’ve had this printer for a month and already main board issues? All i wanted to do was print, it was working fine the day before! All my equipment is on a APC battery backup… Sigh…
Now that you’ve seen the video you understand my frustration, lets go to the good news
I wrote Printrbot and they got back to me within two days. They flat out said in the email that according to this video it looks like the USB has failed on the board and asked if i could try to print with an SD card. Well i couldn’t print with the SD card which was strange since I figured if it was the USB connection that went faulty why isn’t the SD card working? Anyways i wrote them back saying that it didn’t work either. They sent out a replacement board, i received it in just a few days. They also attached a shipping label, but i’m going to hold on to this until i know for sure that its the board.
It was a success!
Installing the board was an easy project that took about 30 minutes to fully replace and start printing again. The new board did the trick and the printer is up and running. The only thing I had to do was re-level the Z axis in the code, “M212 Z-1.18” was the leveling for me. There we go..
So its time for me to vent. Why did this board break? is it because USB Micro is made for small devices and not for 3D printers? Does it really matter? I would love to hear your thoughts. But from my stand point i personally think it was the power that failed. The USB Micro socket went with it.. The USB Micro was on there nice and tight with a solid connection. The printer never moves so it’s not like i’m traveling with it and constant disconnection/re-connection. Everytime i used the machine i would shut off the power supply. I shut my devices off. The power supply seemed kinda cheap, some off brand so i replaced the one it came with; with one of mine. I’m currently using an OCZ 850W Power Supply. It will be interseting to see how this holds up after a few more months.
Again, i would love to hear your thoughts and opinions on this matter.
Thanks for reading!
