Step Slider

Steps is the number everyone tweaks constantly and nobody wants to reach into a KSampler to change. Step Slider puts it on the front panel of the Flux Continuum workflow as a simple 0–50 dial, default 25, and hands the result to whichever sampler is active. It's the sampling-steps equivalent of a volume knob: one moving part, does exactly one thing, and does it fine.

How it works

The node takes a FLOAT slider and rounds it to an INT before outputting - the source explicitly rounds rather than truncating, so you can't accidentally land on 24.999 steps. There's no scheduling math, no sigma manipulation; it's a UI convenience that produces the integer your KSampler's steps input expects.

The default of 25 sits right in the working range for Flux Dev: the standing guidance for the family is Euler + normal/beta scheduler at 20–30 steps. If you're running a distilled variant (Lightning/Turbo-style LoRAs), you'd want this much lower - the slider goes down to 0, and those models are tuned for 4–8 steps. That's not this node's problem, but it's worth remembering that "default 25" is a Flux Dev default, not a universal truth.

Inputs and outputs

• value - FLOAT, 0 to 50, default 25, step 1.

Output is one INT (the rounded value). It feeds the sampler's steps input through the workflow's unified control layer, so switching output modules keeps your step count.

Installing it

Ships in robertvoy/ComfyUI-Flux-Continuum:

cd ComfyUI/custom_nodes
git clone https://github.com/robertvoy/ComfyUI-Flux-Continuum

or ComfyUI Manager → "Flux Continuum", then restart. No standalone dependencies.

Where people get burned

The trap isn't the node, it's the assumption that more steps always means better. On converging samplers like Euler, past ~30 steps on Flux Dev you're paying for pixels that stopped changing - the image is already converged and the extra steps are pure render time. If your images look identical at 25 and 50 steps, that's normal, not a broken slider. The slider's 50-step ceiling is generous; in practice you'll spend most of your time between 8 and 30, depending on how far from a distilled model you are.
