I have a checklist pinned next to my controller that I always glance over before pressing go. I find it a helpful reminder as I sometimes proceeded without checking z between tool changes, not changing the endmill, wrong gcode file, spanners on the surface.
Does anybody else have a similar checklist or have suggestions about what else to add?
What a great idea - and for visual learners as well.
Is it helpful to add ‘… in correct location with respect to program set-up’ to ‘Z probed’ (i.e., work surface vs waste board surface), or is that covered in your ‘Home X Y Reference’?
I am very new to CNC work, so this may not be an important addition.
To me, “Home XY reference” covers it.
Are not a lot of us, but you do come across as quite the machine builder!!
Great Idea…guess what I am going to make for my CNC?
Andy. Nice. Did you draw all those symbols by hand? I would add “Correct speed/feed/depth of cut?” and “Dust extraction on?”
Last step. Push play. Keep finger on digital estop button and hope we programmed everything right!
Critical steps I’ve tried to integrate into the post processor to produce controller prompts, forcing me to acknowledge (and check).
Examples of my workflow include,
- prompting me to verify bit and RPM for Makita router
- prompting me to adjust WCS offset (if any)
I’ve also tried to automate certain parts like connecting router and vacuum to turn on together.
Great feedback. Thank you.
Interesting. I suppose a checklist is a means to capture best practice. Takes me back to shipping; they guys on the refinery docks had so many checklists that they had a checklist for their checklists.
I do little sketches as i can scan them quickly as i find reading words cumbersome. What i do note is that drawing my own sketches i find more noticeable no matter how rough they maybe.
I am a well practiced pause-button-hoverer. The recent FAQ on controller locking and waiting for the buffer to clear following a stop was a great tip.
Looks like you are using a VFD, otherwise I’d add “turn spindle and dust collection on”
Maybe “remove and stow probe magnet” BEFORE the turn on spindle part
I have the pleasure of owning a “dodgy” probe that is wired backwards: no magnet needed, happy days.
“Vacuum on”: interesting one. I often dont start the vacuum until a carve gets going so that i can hear if anything is going wrong.
I do have a spindle, but i have to check that it is on and not in a tripped state. Fortunately since getting a braking resistor tripped states are rare but me firgetting to switch it on is quite common and probably why created the checklist in the first place.
I have thought of one more myself: “saftey specs on”. After tinkering i can find them propped on my head rather than over my eyes.
Id Bitmap that and carve it out next. My plan is to carve everything I want for my machine to help me learn before I tackle some some other projects with it. why buy when you can make you own right lol
Thats exactly how i’m feeling right now! Built my table - But i’d love to make some drawers, enclosure, etc - Figured the best practice is on things I need and can use, instead of just putting it in the garbage once I make something I don’t need.
