IDEX Setup problem

Chriss

Hi *,

I have a strange problem with my IDEX 2nd print head, the first head works as expected. So I created a 2nd extruder in PS/SS and tried to print with that. The result is that the left head moves (T0) and the right head heated and extrudes. :?
The heater at the left (T0) gets heated too.

I'm missing the kinematic declaration for the corexy

Put it right below the printer name

Where do you see "M593 ..." ? I'm unable to find it

M669 K1
I agree that it is missing, bit "K1"? The printer is a Cartesian. I guess that I need "M669 K0", don't I?

@chriss
If it's cartesian, you won't need the M669 line, sorry my bad.

Why is the line with 'X3' outcommented? It should work IMHO

The M593 line is near the end of config.g.

I added it anyway, I thik that it is a good habit.

I have no idea to be honest. I think that it is a glitch from the build time. I changed that and added a X0 to the "T0" too.

The M593 line is near the end of config.g.

Found and fixed it.

Anyway, THANK you very, very much! The missing X3 in the M563 did it. That is obvious that it can not work if the mapping is not correct.

I have a other question now.. regarding the standby temperature... Is there a way to calculate that? Something like "StandbyTemp={Temp-50}" ? I see no way (at the moment) to set the standby temp in PS.

Your config.g doesn't set G10 P0 Rnnn Smmm temps at the moment. Same for P1...

AFAIK, you can't refer to a temp you just have set. But you can try to use config-override to calculate stdby temp when you've set active temp in config.g. (with G10...)

True, I had no reason to do so till now. The slicer sets the temp based on the filament, this printer is my first multitool setup.

AFAIK, you can't refer to a temp you just have set. But you can try to use config-override to calculate stdby temp when you've set active temp in config.g. (with G10...)

Got it. I will not over engineer for now. I will set a fixed standby temp in the tool change files and that's it. This printer is mainly for PLA and PETG, so the standby temp will be very much the same for both materials.

Thanks again for your help and your input! I appreciate it....

Cheers, Chriss

o_lampe

@chriss
Setting standby temps (and start the heaters) will only work for tools in either active or standby state.
Unfortunately T1 is off at the beginning, so I wrote a few lines in config.g to toggle between tools

T0 P0   ; activate tool 0 but don't run the toolchange macros
G10 P0 Rnnn Smmm
T1 P0    ; activate tool1 without macros
G10 P1 Riii Sjjj
T0   ; activate T0 again (T1 is in standby then)

Chriss

@o_lampe

Yes.... true... that is a good idea. I have to think about that.
My idea was to set the standby temp only when I release the tool.

In theory is there no need to heat up a tool when you do not use it for printing. My idea is to pint a purge line with the 2nd tool too if I'm going to use it, or better: Always have a purge tower when I use both tools.
The 2nd tool will get activated when it gets used the first time.
With the downside that this first use takes longer than for the heatup time.

It depends of the future use of the printer:
Mainly two filaments=Standby heating from beginning
Mainly one filament=Standby heating at the first use of the tool.

@chriss for my chimera, I have a few lines in my start gcode in the slicer that are very similar to @o_lampe 's code. I set the standby/active temps using the placeholders in PrusaSlicer and cycle the tools to set them active/standby.
If you only want to preheat one tool, then you can always comment out that line when slicing that file (or make the standby temperature very low).
I find it's a per-print setting so tend to cover those things the the slicer rather than in the machine

o_lampe

@engikeneer @Chriss
that's even better! Having various printer profiles for single or dual extrusion you don't have to comment out or overwrite anything. Just select the propper profile.
