First Print diagnosis please

Hi, finally got my printer built up and working (however I think my print fan is dead on arrival). Below is my first print. Could anyone please tell me the cause of the jagged artifacts on the print. The rest of the print is pretty good.

Regards

Rob

Re: First Print diagnosis please

Hi Rob

Print fan. Test it with a 9volt battery. It probably is OK. You need it only with PLA and it has to be turned on is the slicer, usually after a couple of layers have been printed. If it doesn't work when it is turned on, then it's probably that you have the connector wrong way around.

The marks on the print - that looks like the seam; the point at which the perimeters start and finish.

Generally, you will always get this, but there are things you can do to hide it. You will have to look at the various settings in your slicer to see what settings are available for seam hiding.

You may also need to reduce the filament feed rate slightly - there should be some sort of "flow tweak" setting - set at about 97% to start with.

Thanks for the reply. I have double checked the fan connector and it is in the correct orientation. I have tried checking it is working with the lcd display. Like Joseph shows in his video. But it doesn't spin up. I'll use a 9v battery when I've popped to the shop later. I assume I'll need to remove the connector to check it across the terminals.

As for the seam. I'm using the 1.75mm slic3r settings from the drivers package. I'll try and adjust the flow rate down to 97 as you suggested. Do you have any idea what else I could improve in slic3r?

Regards

Hi Rob

Yes, just remove the connector, push 2 wires into it and then connect them to the battery.

If it's working with the battery but not working via the LCD panel, then either the polarity is incorrect, it is plugged into the wrong socket.

Really sorry, but I don't use Slic3r so I can't advise regarding settings. All printers are different and the default settings published by PR are just a guide to get you started. You then have to make adjustments based on part tolerances, build, environment and filament used.

Yes, it's a bit of learning, but you will get there quickly.

Hi Rob,

I thought also that my fan was not operational. When doing the fan test shown in the video, you must activate the fan at the setting by pushing the control knob in the same manner used to activate the menu and select items from the menu. Just going to the setting without pushing the button does nothing.

Hey Rob, If your fan doesnt work with the 9V test mentioned by peter, you may wanna peel the sticker off of it and check the solder connections. I had an issue with a loose solder joint on my fan. Fixed pretty easily just by resolding it back into place. See picture:

The fan did indeed work it just didn't have the gcode required to turn it on! Used Cura and it came on 🙂 just gotta sort my 1st layer issues out now
