@Michael_Scholtz just to be clear I know this, was just pointing out that some do not explain their answers. The logical reasoning why a solution would work.
Thanks for clarifying for the others who read these post.
@Adam_Steinmark try just swapping the stepper drivers around and see if there is a change.
What brand and make of printer is this?
I offer one on one via Skype or phone through my online store. Just in case you want it done quicker.
Printrbot Simple Metal is the machine. Replacing the motor seems to have helped a lot but hasn’t completely solved the issue. I’ll post a new pic once the new benchy finishes printing. I don’t think skype would help too much but thank you for the offer, I may change my mind and take you up on it if I can’t seem to fix the issue. I checked the printrboard and everything looks fine but I did notice a burn mark on the connector from the ATX PSU.
Final update. Issue was that the PC blower I installed was drawing too much power. Swapped back in the tiny stock fan and its running fine now. Thanks for the help guys.
lol, no fair, i would have said the fan had you said you added a bigger fan.
and i would have told you tune pid loops, set fan for cooling filament to low speeds and change fan profiles as that much more air movement causes heat loss at hotend. even the mk2 prusa, newest prusa design, had issues with the blower fan and had to adjust the profiles
Yeah I didn’t think it was relevant information sorry. Is it possible to set fan speed to vary based on print speed or layer time? And the hotend pid loop is perfectly fine.
@Adam_Steinmark yes,settings are in Slic3r configs or under cooling for other programs like simply 3d.
You can adjust the fan however you want as long as your board supports it. Some label it pwm fan.
Probably the easiest way is to check via your lcd menu options and look for a fan adjustments.
Or the real easy way, via PC interface like repetier host via manual tab and easy settings off.
Check out makers muse on YouTube for his many tutorials, or Joel 3d printing nerd, etc.
I will be putting up more I do on this soon and will try to do a live stream on how to save an air print.
@Adam_Steinmark also, if fan moves a lot of air, it is possible that the hotend could not keep up or your fan draws too much current and your pulling too much power for the MCU side of control board. MCU and hotend plus any accessories are usually on one rail while other 10-15amp side is just for the heat bed.
So can try pulling power from other side as ground is shared and use just the signal via a jumper
@Adam_Steinmark and one last thing forgot to mention about Skype, I use the share screens feature to help you walk through the whole process as I see what you see or you can see me make changes to firmware plus if on a web cam can just point and shoot to show something.
Most always think it’s just to video conference, but it’s a tool and it’s how you use the tool(s) that make them useful.
Just had to get that out.
