Hallo,
ich habe folgende Frage:
Kann man den KTC auch mit als manuellen Wechsler einrichten?

[TypQxQ]

Hi! If I understand your question, you want to manually change tool?
KTC can do that. The toolunlock macro can then be set to issue a M600 pause for example.

[ott-Klaus]

Ok, danke!
Ich habe von BTT Hiermit Crab V2, und möchte so meine Werkzeuge wechseln bzw. Anlegen.

Hi. Thanks for the project. I'm working on switching an implementation to version 2. It's not entirely clear what the preferred way would be to establish that a tool is already loaded at startup (which I know from sensors). I'm using the command KTC_SET_ACTIVE_TOOL to manually set the active tool, but I also need to set the offsets and other tool parameters like shaper parameters and I don't think I'll have access to those parameters in a regular macro like I do in the tool select gcode which has access to the myself object. Any guidance would be appreciated.

[TypQxQ]

Hi! Sorry for late reply 😞
It's easy to get the selected tool from any macro. Here is a sample:

[gcode_macro test_get_offset]
gcode:
  {%set selected_tool = printer['ktc_tool '~printer.ktc.active_tool]%}
  RESPOND MSG="Selected tool is: {selected_tool.name}."
  RESPOND MSG="Tool parameter: {selected_tool.offset}."

I use Search Printer Objects macro in mainsail to search and browse the objects I need.

Hope this helps and good luck!

Thanks Andrei. Very helpful.

A few other things I came across. It looks like you have to change the tool state at the end of the select/deselect GCODE using something like KTC_SET_STATE TOOL={myself.name} STATE=SELECTED. Easy enough to do, but it's not in the examples you provided. Additionally, there are some references in the deselect gcode example that access {myself.park} instead of {myself.params_park}. I'm happy to update these and do a pull request if it helps.

I welcome all the help 😄
I have some limited time right now...

Hi,

I just wanted to say this project looks awesome. I'm trying to get it installed on a custom 8ft printer I have but honestly I'm quite confused on what to set up after installation. I'm using a metal version of the RatRig VCore 3 Tool Changer I bought on Aliexpress but I don't know what exactly I need to set up after installation.

I'm currently using the sample config and the tool macros but that's as far as I've gotten.

Any help would be super appreciated

[TypQxQ]

Hi,

I have no experience with the RatRig VCore 3 Tool Changer.
This is not plug and play and I don't know if anyone uses it on this system. You can try asking on the RatRig Discord for help.
Any specifics, I can try to help.

What is causing this issue? I ran the T0 macro

T0
KTC Tool 0 Selecting.
Unknown tool already mounted.Can't automatically deselect unknown tool before selecting new tool.
KTC Tool 0 failed to select: Unknown tool already mounted.Can't automatically deselect unknown tool before selecting new tool.
KTC Toolchanger is in ERROR state.

Then if I press it a second time this happens
Internal error on command:"KTC_T0"
Internal error on command:"_SET_ACTIVE_TOOL"
Internal error on command:"T0"

I have the same problem, did you figure it out eventually?

[mg1975-hub]

I am also having the same issue. Were either of you able to correct it?

[goldenfaeron]

Nope sadly not. I just went on and wrote my own small set of macros which work perfectly in combination with orca slicer. It will generate the T_ calls and you can trigger e.g. wipe /purge macros in e.g. in the filament start / stop section and so on

[mg1975-hub]

Thanks for the heads up. Ive been trying to get my IDEX to work with ERCF and HH with no luck. Was hoping the KTC would be the answer as it shows the layout on the complete config. Would you mind sharing the macros?

[goldenfaeron]

Sure, I can do that as soon as I am in my Lab again. But that's probably around Wednesday-Friday next week. Might have a somewhat recent backup on my laptop with me, can check later

[TypQxQ]

Please attach logs.

Did you get this sorted?
Sorry I missed your reply, Try opening a new topic so I can follow it. Gets a bit messy inside the welcome topic.
Also please attach klippy.log and ktc.log

[Fuppdisch]

Thanks for your work, it really looks good.
I also learn at the moment how your ktc has to be set up. Not being a programmer its of course not that easy.
A short youtube video that shows the steps to set this up would be a dream.
