I think the issue from the board.
The last step is:
Replace the thermistor .


I think that you are correct - so I have decided to build a hybrid.

I have an older GT2560 board - not one designed for the A10 and a 2004 LCD on their way - in theory, with a few cabling changes and some new LCD ...

More information.

unplugging everything except power/motors from the board gives me the same temp readings, a quick check of resistance on the thermistors gives me readings in the 100k region - which leads me to think that the board is fried, not the bed/hot end.

Does this feel likely ?

1.Check the thermistor
100K ,ntc(80~120K is normal)
2.Remove the thermistor off then check the LCD info correct or not

Yes I do have one - do you have some potted instructions on what / how to check please ?

Unfortunately all connections are solid - at least all of the non-soldered ones are solid.

It is very frustrating that I cannot find a decent trouble-shooting guide..

What I am thinking of doing it buying a new GT2560 board, because it appears that the issue is there, from the limited information ...

My A10 has been pretty good for the last couple of months, but mid-print last night the temperature sensors are reading wildly incorrectly and the ensuing chaos was pretty funny.

However I cannot see a reason for this.

The measured room Temp is 21C.
- The IR Measured Nozzle Temp is 20.7C
- The ...

I thought I would update this after a couple of months.

Short Answer - Cura is awesome and with a large amount of trial and error I have a pretty decent 3d printer.

Much longer answer -

I have no desire to install windows, never have, never will, it is just not my thing.

Issues I hit

In 'Manage Printers' / Machine Settings take a look at the Start G-Code


I BET that the two lines
are in there and either commenting them out with a semi colon or deleting them entirely will fix this.

I am not sure that the following two lines are useful in the Start G-code section.


M109 S200;Heating nozzle
M190 S60;Heating bed


This appears to override Nozzle and Bed temp to 200/60 that are taken from Filament or Custom profiles.

Commenting them out, or zapping them entirely returns ...

I am a Mac user.

I do not have, and nor do I want or need, a Windows machine.

One of the selling points of this A10 printer was that it works with Windows/Mac/ Linux.

This is my first foray into the world of 3D printers and thus far I have been goofing around with Slic3r, which seems to be ...
