454 Control: quick start

Opening the app to a finished cut. About ten minutes the first time, once you have your machine details entered; a minute or two after that. Every part of the screen is covered in the Control reference.

  1. Open 454 Control in Chrome or Edge on a desktop. Nothing to install.
  2. Press Connect when it asks, and pick your controller from the browser’s list. After the first time the button says Reconnect and skips the picker.
  3. Home the machine when prompted. 454 Control asks as soon as you connect, and a job won’t start without it.

Once, in Settings (the gear, top right). Everything saves in your browser as you change it.

  • Work area — filled in from the controller when you connect, or pick your machine from the list (or type a size) and it stays as you set it.
  • Spindle — router or VFD, and the spin-up wait after the spindle starts. Default 7 seconds.
  • Start & stop high — leave this on. It keeps the bit above clamps.
  • Lift at tool changes and job end — how far below the top of travel to go. Default 2 mm.
  • Tool-change position — front centre by default, or capture your own.
  • Park at the end of a job — the back centre by default, like Carbide Motion; capture a position to park somewhere else.
  • Controller config — the controller’s own $ settings, read when you connect. Check controller settings looks them over for anything that would trip 454 Control up, and shows each axis’s range.
  • BitSetter — tick it, jog the tool over the button, press Capture position, then Test: it touches off once and reports, without changing anything.
  • BitZero — tick it, choose v1 or v2, and enter the plate thickness you measured with calipers. Measure your own, to a tenth of a millimetre: a BitZero v2 is about 15.5 mm from its bottom face to the top, and every depth you cut is off by whatever this number is off.
  1. Fit the first bit and jog over the corner of your stock with Jog & zero.
  2. Set X and Y where the job’s origin should be, matching how the file was posted.
  3. Probe Z with the BitZero: clip the lead to the tool, put the plate on the stock, jog the tip 2–10 mm above it, verify the circuit by touching the pin to the plate, then probe.
  4. Paper-test it: jog to Z0 and check the drag on a sheet of paper.
  1. Say yes to the BitSetter. If you have one set up, setting Z zero offers to measure the tool straight away. That makes it the reference every other tool is measured against. The Probe section shows the BitSetter’s status; if it’s switched on but can’t be used, it says why.
  1. Open a G-code file and look at the 3D view. Drag to orbit, scroll to zoom.
  2. Read the Checks tab. Anything GRBL would reject is listed there with its line.
  3. Look at Toolpaths. Each operation with its tool, depth, feeds and time. Click one to jump the preview to it.
  4. Scrub the preview to watch the cut before it happens.
  1. Press Start. A summary appears before anything moves: extents, tools, what will be added, where the bit waits during spin-up, and how the job will end.
  2. Read it, then press Start job. The control bar over the preview shows progress, position, and Hold, Resume and STOP.
  3. At a tool change the machine lifts, stops the spindle, moves to the tool-change position and waits. Change the bit, then press Tool changed — continue. With a BitSetter the new tool is measured automatically.
  4. At the end it lifts, stops the spindle, returns to the job’s XY zero, then parks at the back centre.

A new tool is a different length from the last one, so without a BitSetter to measure it, Z has to be zeroed again before it cuts. 454 Control won’t let that be missed:

  1. You choose at Start. If the file changes tools after cutting has begun and the BitSetter isn’t set up, a dialog says so before anything moves. Set up the BitSetter opens Settings instead of starting; Re-zero at each change starts the job.
  2. At each change, zero Z for the new tool. The tool-change prompt offers Probe with BitZero and Jog & zero Z. The job waits, stopped, while you do it.
  3. Then continue. Tool changed — continue stays disabled until Z has been zeroed for the new tool. When you continue, the machine lifts to the top before moving back to the work, since the tip is still down on the stock.

The first tool, loaded before anything is cut, doesn’t need re-zeroing: that’s the one you zeroed with.

Situation What to do
Need to pause Hold. The machine stops with the spindle running; Resume carries on.
Something is about to be hit STOP (red). Immediate halt: motion and spindle stop at once.
Need to end the job early End job. The machine slows to a stop, then lifts clear, stops the spindle, returns to XY zero and parks, the same as a finished job.
Stopped and want to carry on The Recover box is filled in with the line where cutting stopped. Check it in the preview, then press Recover.
Probe failed The tool was too far from the plate. Unlock when asked, jog closer, probe again.
Machine says Alarm Home it, or unlock if you know why it alarmed.
