Geeetech

Thanks Gerry, some more great tips there. I did also lubricate the smooth rods, though already did it with WD40 not the 3 in 1 you suggested. Any particular reason I should avoid WD40 by the way, I'm curious?

What's happening is on raising (sometimes falling) one side starts to stick, when that ...

It was definitely a power supply issue. I have a replacement power supply of a different max capacity now that is working correctly (though it doesn't fit on the frame)

I replaced the couplings with two new ones I bought separately, as well as lubricated the threaded rods to ensure that they move smoothly using the 'drop test'. I also filed out the hole in the acrylic a little more to make sure it was rotating smoothly.

The z-axis is still not moving correctly and ...

I bought a Geeetech i3 pro-c and it's unusable. I've spent hours and had lots of replacement parts and still the z-axis is sticking (the original power supply that came with wasn't powerful enough to even work the heat bed). I bought the ender-3 afterwards and it's been very simple to build and get ...

Update. The heating for Extruder 1 and Extruder 2 appears to be functioning, but fails completely when enabling the Heat Bed. Setting the heat bed target temperature back to 0 again seemed to restore life.

I also note that whilst Extruder 1 or 2 is enabled the axis movement becomes unresponsive or ...

I'm having some trouble with the Z-axis sticking when going up, and this is more common when the Z-axis is starting from a low point. There are sometimes small issues when going down, but it is more pronounced when going up. It is only the right side sticking, which causes the height to become ...

By motherboard do you mean the GT2560 or within the power supply?

After building my Prusa i3 Pro C from Geeetech I'm trying to diagnose an issue with printing. When setting the temperature for the heat bed and extruders, the power seems to cut out (fans disabled, and some of the LEDs get disabled). This is only fixed if I reconnect the USB cable (or if USB is not ...
