Ha! Series 1! I have serial number 34 and it was still printing great!
I say was because I recently decided to rebuild it just to get rid of the wood.
Really good printers. Too bad they priced themselves out of business.
The end is loose.
You need to re-tighten it occasionally.
Here's the instructions.
Your best bet is to take the whole thing apart, clean it very well, then reassemble.
Unless I'm missing something the Palette doesn't attach to the extruder at all. It fuses filaments together internally then feeds them to the printer like any other filament. The work is done in the slicer so as long as you use their slicer, it just works.
So you have to figure out why it's not homing.
Does the X axis make it to the homing switch? If not, what's stopping it.
Does the Y axis make it to the homing switch? If not, what's stopping it.
If you can post a video of the homing sequence, there may be something obvious in it.
Look for loose...
Isn't good?? It's 2.5mm across a 18" glass bed. The glass itself is probably that uneven.
We're talking mm's.
Here's mine and it prints perfectly.
Can you show us what yours looks like? Must be close to perfect if you think these are bad.
Extrusion width isn't just some arbitrary number.
It might be printing better but you need to tune your extruder to make sure 20mm is really 20mm.
I find the default settings are way off.
Here's a good guide.
Pay attention to the extruder...
Can't really tell from those pictures. Don't see the fan wires in them.
Try this, find the fan connection on the board and flip it the other way. They are polarity sensitive so maybe it's backwards.
A meter is your best bet
If you want help from here a few pictures would really help, otherwise, you can call support directly and they may be able to walk you through it.
First thing to do is follow the wires coming off the fans. Are they connected to constant 12v?
Do you have a meter to measure the voltage?
