LC Sampler Configure Simple (pipe)

This is the pipe-flavored version of LC Sampler Configure Simple, and it has a nice trick up its sleeve: it speaks both pipe-world and single-CFG world. You get one CFG, steps, denoise, sampler, and scheduler - but instead of just spitting out sockets, it also packs everything into an LC_PIPE that plays nice with the dual-pass machinery.

The headline behavior is in the author's own description: when it packs the pipe, it sets step_swap = 0 and cfg_2 = cfg. What that means in practice: a consumer that expects the full dual-pass key set (like the pipe-fed sampler stack) sees a "swap at step zero, second CFG equals the first" schedule, which effectively degrades to the single-pass behavior you asked for. You don't have to know whether your downstream graph wants the dual-pass shape - this node satisfies both.

How to use it

• pipe (optional) - an incoming LC_PIPE. This node's sampler keys overwrite matching keys; every other field passes through. Leave it empty and it builds a fresh bundle from the widgets.
• Widgets: total_steps, detailer_steps, denoise, cfg, sampler_name, scheduler - same dials as the non-pipe Simple variant.

Outputs: pipe, then total_steps, cfg, denoise, sampler_name, scheduler, detailer_steps. So you can ride the pipe onward for the rest of the graph and still wire the plain values straight into a KSampler if that's more convenient at the edge.

Install

Same pack as the rest of LC123 - Manager (search "LC123") or:

cd ComfyUI/custom_nodes
git clone https://github.com/lonecatone23/ComfyUI_LC123_nodes

Restart. No extra pip packages (ComfyUI's torch/numpy suffice), MIT licensed. On cloud-hosted ComfyUI, LC123 must be requested or run locally.

The take

It's a nice compatibility bridge rather than a must-have: if your graph is all pipes, this is the single-CFG config node that doesn't force you to abandon the bundle. If your graph is all explicit wires, the plain Simple version is cleaner - fewer sockets to trip over, and no LC_PIPE type hanging in the middle of it. Pick based on whether the pipe is already your pattern.
