## Code
**!! I AM OPEN FOR ANY SUGGESTIONS OF IMPROVEMENT TO THIS CODE !!**
Copy mmu_additional.cfg to your printer config directory mmu/base/ and include it in your printer.cfg below all of the mmu includes via [include mmu/base/mmu_additional.cfg]
[thisiscam](https://github.com/thisiscam) has created the ercf_additional.cfg which, once you include it in your printer.cfg should do the work and the modification of the ercf_software.cfg listed below is no longer needed. As I am currently rebuilding my ERCF this is untested by me and thisiscam already announced an update :)
-> For know I will leave the code below as information.
I use [Happy Hare](https://github.com/moggieuk/ERCF-Software-V3) with my ERCF. So I only tested it with this code. On your running ERCF config you'll need to modify the "_ERCF_FORM_TIP_STANDALONE" macro in your "ercf_software.cfg"
You will need to adjust the parameters in mmu_addtional as well like setting up your cutter location, speeds, etc. More information in the cfg file itself.
As I am still testing I am really open for improvements of the Code. As I have no drag chain due to canbus the best position for me was in the back of my printer. If you use a drag chain you maybe need to adjust the gcode below to avoid any collision with your drag chain.
In the Machine start g-Code you need to add this (i a separate line)
```
ERCF_CHANGE_TOOL TOOL={initial_tool} STANDALONE=1
```
### Modification of "ercf_software.cfg"
We will use the STANDALONE=1 mode and repleace the tip forming macro. So set the
```
variable_standalone = 1 # 0 slicer, 1 Happy Hare macro (turn off in slicer)
```
Adjustment of the Tip Forming macro
