FA81 sounds right.

Thanks for the reply, I thought that may be the case, with regards to the serial number could it be FA81? I’m not sure if it’s an a or a 4.

An F serial number means fully assembled, which was only offered during the Kickstarter if memory serves, but I don't think that many fully assembled Kickstarter units were produced. At any rate, that unit is ~5 years old.

It is normal for a power supply to change slightly in voltage output when load changes. Typically this is 3-5%. This is very audible as our ears are finally tuned to frequency shifts, but a speed change of the motor of even 5% is not enough to cause noticeable diameter differences.

At any rate, if you want to solve it, the best bet is to require to use two separate power supplies.

How do peeps! I have machine number F481, I got it second hand and the only thing I can tell you is it hadn’t been used until I received it, I believe it to be a pre built one so it only needed a few little bits doing to get it ready for extrusion which I did and then ran through the checks. I’m having a problem with the motor bogging down when ever the pid kicks in.

Is there a fix for this or am I doing something wrong?
I’m extruding pla (I know it’s the difficult one to extrude but that’s all I print with and I don’t want to contaminate it with abs) I’m running it at 180 degrees and until the motor bogs down I’m getting quite consistent diameters.

Thanks in advance.
