I was reading on the website under the MK3 GCode generator and read that you can set up as a Direct drive mode. Beneath are the exact words used.
"Direct Drive Mode - Where the 3D Chameleon is replacing your stock extruder (but using the stock motor and wiring) and all filament motions or pauses are skipped to allow stock extruder commands to move the filament."
Does anyone know more about this and how to set it up? I am using the default installation method on my ender 3 but I am having trouble getting it to load and unload properly. It will send the filament to the extruder but my extruder wont grab the filament. I was hoping if I could just bypass my extruder altogether and use the chameleon and the extruder it would be a lot simpler. Not sure if its possible just thought I would ask.
Would you have a profile for an Ender 5? I'm trying to do the same
In Direct Drive, you simply use the Y adapter to feed the hotend directly with no extruder in between. To control it, you use the stock extruder cable to drive the 3D Chameleon's drive motor instead of our electronics. The Mk2 allowed this installation method... you can see the full installation video here for it: https://youtube.com/video/GaWiYqWP_s4 Ignore any of the commands or the assembly instructions in it... the original one was a kit version. But in it, you can see the 3D Chameleon replaces the Ender 3 extruder directly. (Here's a quick snapshot of the entire thing installed:
From there, you need to follow this video to install the post processor for PrusaSlicer to drive it. https://youtube.com/video/4mpSn5O6pAQ Place it in direct drive mode, by using 10 pulses. Then, 1-4 pulses switch directly to that color... and 5 pulses home it. (Technically, so does 6 and 7.) You'll need to add the specific commands in your gcode to drive the extruder forward and backwards to load/unload the filament. You can see our PrusaMini installation as an example. If you take a look at the same code attached to that installation video, you can see how I did it on the Mk2. You can also see the Prusa Mini profile for the commands I used... yours will be very similar. Here's the Prusa Mini Mk3 profile: https://1drv.ms/u/s!Av2Y103sCRZ3m-1BEGOERH2t7oJbBA?e=3sRFu8 Bill
