Shift Cards
A workshop note on job cards that record tooling, feeds, speeds and material for the next run.
Small handovers prevent expensive repeats. In South African shared workshops, the next person often needs to know which bit is fitted, where zero was set, and whether the last sheet already shifted once. Shift Cards turns that into a simple record for desktop CNC use.
Shift Cards are written for the moment after a cut, when the useful details are still on the bench and not yet lost to memory. A card should capture cutter type, stick-out, zero position, hold-down method, and any sheet movement noticed during the run.
Details worth writing on the card
- Machine name and operator noted
- Photo shows cutter, clamps, and zero position
- Job file name matches the saved folder
- Bit size, material, and datum written clearly
A Shift Card sits between the bench and the saved file. The machine settings belong on the card, while the hardware choice belongs on the relevant machine pages. That split helps the next operator repeat the part without hunting through old messages.
Handovers between afternoon and morning
Shift Cards keep the next run from starting with guesswork. Job cards that record tooling, feeds, speeds, and material make it possible to cut the same part again without rebuilding the process from memory.
In a shared workshop, the second person often meets a part-finished setup with only chips and offcuts as clues. Shift Cards records the sheet size, feed, spindle speed, pass depth, and any change made after the first test cut. That matters on desktop CNC work where MDF, birch ply, acrylic, and aluminium can all appear on the same bench in one week.
Write the card before the spoilboard is swept clean. Include where X0 Y0 and Z0 were picked up, whether tabs held properly, and if the vacuum or clamps needed repositioning. One small card near the controller can prevent a repeated mistake on the next sheet.
What the next operator needs
A useful Shift Card gives the next person enough information to load the right cutter and check the setup before pressing start. It should mention the material thickness measured on the day, not only the nominal stock size. Notes about chatter, melting, chip packing, or edge finish are often more valuable than a perfect-looking screenshot.
Use Shift Cards with the related workshop records, not as a replacement for drawings or CAM files. Keep the completed card with the job folder, then check tooling and workholding before moving the machine or packing anything for collection. For a desktop CNC comparison, tell us what you cut most often and how much bench space the machine will have.
- Recorded feeds and spindle speed
- Zero point marked before teardown
- Operator notes kept with the file
Bench realities in South African workshops
Many small shops here share one router across prototypes, signage, fixtures, and student work. That makes handover notes more important, because the person starting the next run may not be the person who dialled in the first one. Shift Cards works best when each card names the exact stock used, including offcut origin if the full sheet was broken down earlier.
Humidity at the coast can affect storage condition and board flatness before clamping. Inland dust can hide witness marks and make it harder to see whether the cutter has rubbed instead of cut. Power cuts also matter, so note whether the previous run was interrupted and where the job was restarted.

Card fields that earn their space
A workshop note on job cards that record tooling, feeds, speeds and material for the next run.
The most useful card is filled in on the same day as the cut while the bench still shows what changed. Pair it with the project record, cutter list, and any spoilboard notes when a lecturer, buyer, or workshop lead asks how the part was produced.
