If you are still running stock firmware then your hard limit is about 230 and there is nothing you can do to change it as long as you are running stock.

That's the bit I needed to know/understand. Thanks for the help, Carl.

So .... what is the hard limit?

If you had access to the firmware you could set that hard limit to whatever. But there is no material out there that should require more than 320.

So are you saying here, Carl that the hard limit is set for 320? That should be more than adequate. I have some cleaning filament that I've run through at the normal setting (220) and it's helped quite a bit but could be better. They say to truly clean it you need to get the temperature up as high as you can within reason. I figure around 260 should help - higher if I can safely get it for a few minutes.

I am saying that if you have access to the firmware then there is no hard limit as you can change it to whatever you want. If you did have access and change it then you should never go over 320.

If you are still running stock firmware then your hard limit is about 230 and there is nothing you can do to change it as long as you are running stock.

If you are running Repetier firmware then you just need to go into configuration.h and change the following setting to whatever you feel is SAFE.

#define MAXTEMP 275

275 is the default value for Repetier.

I believe it would be 220. The machine is designed for their filament which is a special formula that melts at 10 to 20 degrees lower than the standard materials.

Thanks, Carl but it's not really the question I was asking. I'm presuming (*) I can demand any temperature I want by suitably  configuring a gcode file. What I want to know is the maximum temperature I can ask for before the extruder/heater won't go up any higher.

* Unless XYZ limits it outside of the gcode - wouldn't put that past them.

The firmware has a built in limit to keep you are a failure from damaging the hot end. Unless you are running Repetier firmware you will not be able to change that hard limit. Even then changing it carries the risk of damage since that stock hot end is not made for higher temps. It lacks adequate cooling and the pcb and stuff located above it can be damage by the excessive heat it was not intended to be exposed to. If you had access to the firmware you could set that hard limit to whatever. But there is no material out there that should require more than 320.

Can anyone tell me what is the maximum extruder temperature the Da Vinci 1.0 will go to please?
